Your gas stove might be making your asthma worse. Here’s what you can do about it

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/nusrat-homaira-1199433">Nusrat Homaira</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a></em></p> <p>We may think of air pollution as an outdoor problem, made up of car exhaust and smog. But if the air inside our homes is polluted, this can also affect our health.</p> <p>In Australia, around 12% of childhood asthma can <a href="https://pubmed.ncbi.nlm.nih.gov/29642816/">be attributed</a> to gas stoves and the toxic chemicals they release into the air. And while there’s a growing push to phase out gas indoors, some 38% of Australian households <a href="https://www.mja.com.au/journal/2018/208/7/damp-housing-gas-stoves-and-burden-childhood-asthma-australia">rely on natural gas</a> for cooking.</p> <p>Recommended interventions – such as replacing a gas stove with electric – may not be possible for those who are renting or struggling with the cost of living. This is important because, as our <a href="https://ghrp.biomedcentral.com/articles/10.1186/s41256-024-00361-2">research</a> shows, childhood asthma is more common in socioeconomically disadvantaged areas.</p> <p>If you’re living with gas, here’s how it can affect you or your child’s asthma, and what you can do to improve air quality.</p> <h2>What is asthma?</h2> <p>Asthma is the most common chronic condition in Australian children. The respiratory condition affects <a href="https://www.aihw.gov.au/reports/chronic-respiratory-conditions/asthma">almost</a> 400,000 of those aged aged 14 and under – close to 9% of that age group.</p> <p>Asthma narrows the airways and obstructs airflow, making it hard to breath. Many people manage the condition with inhalers and <a href="https://asthma.org.au/manage-asthma/asthma-action-plan/">asthma action plans</a>. But it can be serious and even fatal. Australian emergency departments saw <a href="https://www.aihw.gov.au/reports/chronic-respiratory-conditions/asthma">56,600 presentations</a> for asthma in 2020-21.</p> <p>While there is no single cause for asthma, both indoor and outdoor air pollution play a <a href="https://pubmed.ncbi.nlm.nih.gov/38247719/">significant role</a>.</p> <p>Being exposed to small <a href="https://aafa.org/asthma/asthma-triggers-causes/air-pollution-smog-asthma/#:%7E:text=Air%20pollution%20can%20increase%20your,if%20you%20already%20have%20asthma.&amp;text=Small%20airborne%20particles%2C%20found%20in,%E2%80%9Cparticulate%20matter%E2%80%9D%20or%20PM.">airborne particles</a> increases your risk of getting asthma, and can aggravate symptoms if you already have it.</p> <h2>Gas stoves release nitrogen dioxide</h2> <p>The gas stoves commonly found in Australian homes release toxic chemicals into the air. They include carbon monoxide (CO), PM₂.₅ (small particles, often from <a href="https://www.epa.vic.gov.au/for-community/environmental-information/air-quality/pm25-particles-in-the-air">smoke</a>), benzene, formaldehyde and nitrogen dioxide (NO₂). All are harmful, but nitrogen dioxide in particular is <a href="https://go.gale.com/ps/i.do?id=GALE%7CA656312383&amp;sid=googleScholar&amp;v=2.1&amp;it=r&amp;linkaccess=abs&amp;issn=00220892&amp;p=AONE&amp;sw=w&amp;userGroupName=anon%7E7027bb9f&amp;aty=open-web-entry">associated</a> with asthma developing and getting <a href="https://www.atsjournals.org/doi/10.1164/rccm.200408-1123OC">worse</a>.</p> <p>Gas heaters can also <a href="https://pubmed.ncbi.nlm.nih.gov/9731022/">produce</a> nitrogen dioxide.</p> <p>As nitrogen dioxide is a tasteless, invisible gas, it’s difficult to know how much is in your air at home unless you have an air monitor. However one US <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2662932/">study</a> showed houses with gas stoves can have nitrogen dioxide levels three times higher than houses with electric stoves.</p> <p>This is particularly concerning for households with children, given children tend to spend <a href="https://pubmed.ncbi.nlm.nih.gov/11477521/">most</a> of their time indoors.</p> <h2>Banning gas</h2> <p>There is a growing push across Australia to replace gas stoves with electric stoves, which are more energy efficient and can reduce indoor air pollution.</p> <p><a href="https://www.premier.vic.gov.au/new-victorian-homes-go-all-electric-2024">Victoria</a> and the <a href="https://www.climatechoices.act.gov.au/energy/canberras-electrification-pathway/preventing-new-gas-network-connections">Australian Capital Territory</a> have announced bans on gas connections in new homes from 2024. Sydney’s Waverley council recently made a similar <a href="https://www.waverley.nsw.gov.au/environment/climate_resilience_and_reducing_emissions/go_electric">move</a>.</p> <p>But until a ban on using household gas appliances is implemented across the country, the problem persists for children who are currently living in old homes or rented properties with gas stoves.</p> <h2>Do exhaust fans in the kitchen help?</h2> <p>Using a high-efficiency <a href="https://pubmed.ncbi.nlm.nih.gov/24750219/">exhaust hood</a> placed over an existing gas cooktop can be effective. They can <a href="https://www.mja.com.au/journal/2018/208/7/damp-housing-gas-stoves-and-burden-childhood-asthma-australia">capture</a> more than 75% of air pollutants and direct them outside.</p> <p>Cooking on the back burner – rather than the front burner – can also <a href="https://pubmed.ncbi.nlm.nih.gov/24750219/">improve their efficiency</a>.</p> <p>However exhaust hoods with lower flow rates, or hoods that don’t vent the air outside, are less effective.</p> <p>And an exhaust hood only improves air quality if you use it. One <a href="https://pubmed.ncbi.nlm.nih.gov/10520075/">study</a> in Melbourne found more than 40% of people didn’t use an exhaust hood regularly while cooking.</p> <p>For many people, installing high-efficiency exhaust hoods will not be practical – especially for those renting or experiencing socio-economic disadvantage.</p> <h2>Natural ventilation</h2> <p>There is a free way to ventilate your home. Keeping windows open during and after cooking will increase air flow and <a href="https://pubmed.ncbi.nlm.nih.gov/32970538/">evidence shows</a> this can improve overall air quality.</p> <p>However this is not always possible, especially during cooler months of the year which can be especially chilly in places such as Victoria and Tasmania.</p> <p>Unfortunately, people are also more likely to use gas heaters during those cooler months.</p> <h2>What about heaters?</h2> <p>There are two kinds of gas heaters, flued and unflued.</p> <p>Like cooking with gas, unflued gas heaters release air pollutants including nitrogen dioxide directly into the home. Flued heaters are better for air quality because they use a chimney, or “flue”, to send emissions outside.</p> <p>If you can, replacing your unflued gas heater with a flued one – or even better, an electric heater – can significantly <a href="https://pubmed.ncbi.nlm.nih.gov/15075170/">alleviate</a> asthma symptoms.</p> <p>If you can’t replace your unflued gas heater, <a href="https://www.health.nsw.gov.au/environment/factsheets/Pages/unflued-gas-heaters.aspx">do not use it overnight</a> in the room where you or your children sleep.</p> <p>Asthma can’t be cured, but its symptoms can be controlled by managing triggers – and this may be easier to do indoors than out. Improving air quality, even in a rented or old property, can help people with asthma breathe more easily.<!-- Below is The Conversation's page counter tag.

How household gas leaks affect your home in Adelaide

<p dir="ltr" style="line-height: 1.38; margin-top: 12pt; margin-bottom: 12pt;"><span style="font-size: 11pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">If you're an Adelaide local, you'll know the city is as notorious for its hot summers as it is for its icy winters. One common necessity across all seasons is the reliance on gas. Be it for the central heating in winter or that gas oven whipping up a delightful roast, we can't really do without it. However, any discussion about gas and electricity supply here would be incomplete without addressing household gas leaks in Adelaide.</span></p> <p dir="ltr" style="line-height: 1.38; margin-top: 18pt; margin-bottom: 4pt;"><span style="font-size: 17pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: bold; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">The Silent Stalker: Gas Leaks</span></p> <p dir="ltr" style="line-height: 1.38; margin-top: 12pt; margin-bottom: 12pt;"><span style="font-size: 11pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">Often undetected and woefully underestimated, gas leaks can become a real concern if not addressed promptly. The main culprit in residential settings usually boils down to faulty gas appliances. An incorrectly installed gas appliance or ageing unit can develop leaks over time, silently emitting gas into your living space.</span></p> <p dir="ltr" style="line-height: 1.38; margin-top: 18pt; margin-bottom: 4pt;"><span style="font-size: 17pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: bold; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">Signs of a Gas Leak</span></p> <p dir="ltr" style="line-height: 1.38; margin-top: 12pt; margin-bottom: 12pt;"><span style="font-size: 11pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">So, what are the </span><a style="text-decoration: none;" href="https://cyberairconditioning.com.au/blog/what-do-gas-leaks-smell-like/"><span style="font-size: 11pt; font-family: Arial,sans-serif; color: #1155cc; background-color: transparent; font-weight: bold; font-style: normal; font-variant: normal; text-decoration: underline; -webkit-text-decoration-skip: none; text-decoration-skip-ink: none; vertical-align: baseline; white-space: pre-wrap;">indicators of a gas leak</span></a><span style="font-size: 11pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">? In the absence of an instinctive warning, we might unknowingly be dealing with a perilous scenario right at our fingertips. Luckily, nature offers us a clear heads-up: our sense of smell. Indeed, that rotten-egg-like aroma you sniff is likely due to the addition of a chemical called Mercaptan to your natural gas supply, which serves as a leak alert. Thus, if your nose detects something unpleasant in the air, it's a credible signal that a gas leak is present.</span></p> <p dir="ltr" style="line-height: 1.38; margin-top: 12pt; margin-bottom: 12pt;"><img src="https://oversixtydev.blob.core.windows.net/media/2023/12/GasLeaks02.jpg" alt="" width="1280" height="720" /></p> <p dir="ltr" style="line-height: 1.38; margin-top: 12pt; margin-bottom: 12pt;"><span style="font-size: 11pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">Apart from the smell, other signs include a higher-than-usual gas bill, dead patches on your lawn, or the persistent sound of a hissing near gas lines.</span></p> <p dir="ltr" style="line-height: 1.38; margin-top: 12pt; margin-bottom: 12pt;"><span style="font-size: 11pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">So what do you do if you suspect a gas leak? Well, common sense and caution are your top mates here.</span></p> <p dir="ltr" style="line-height: 1.38; margin-top: 18pt; margin-bottom: 4pt;"><span style="font-size: 17pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: bold; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">When a Gas Leak Occurs</span></p> <p dir="ltr" style="line-height: 1.38; margin-top: 12pt; margin-bottom: 12pt;"><span style="font-size: 11pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">Start by making sure you're not creating an ignition source. This means avoiding lighting matches or using a cigarette lighter inside your home. Similarly, don't operate electrical equipment close to the suspected leak area.</span></p> <p dir="ltr" style="line-height: 1.38; margin-top: 12pt; margin-bottom: 12pt;"><span style="font-size: 11pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">Ensuring good air circulation is paramount in such situations, so swing open your doors and windows to facilitate the diffusion of the gas. If the odour is overpowering, promptly guide your loved ones and pets to a secure location outdoors.</span></p> <p dir="ltr" style="line-height: 1.38; margin-top: 12pt; margin-bottom: 12pt;"><img src="https://oversixtydev.blob.core.windows.net/media/2023/12/GasLeaks03.jpg" alt="" width="1280" height="720" /></p> <p dir="ltr" style="line-height: 1.38; margin-top: 12pt; margin-bottom: 12pt;"><span style="font-size: 11pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">Once you're in a safe position, immediately dial emergency services. And remember, attending to a gas leak isn't a task you just anyone can do.</span></p> <p dir="ltr" style="line-height: 1.38; margin-top: 18pt; margin-bottom: 4pt;"><span style="font-size: 17pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: bold; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">What Happens If a Gas Leak Goes Unnoticed</span></p> <p dir="ltr" style="line-height: 1.38; margin-top: 12pt; margin-bottom: 12pt;"><span style="font-size: 11pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">A frequently unobserved gas leak can pose significant dangers in your home. While it's crucial to heed the signs, smell gas, and call in professional help, it's also vital to understand what can happen if a gas leak goes unnoticed. As Adelaide homeowners, it's our responsibility to remain well-informed on the consequences of an ignored gas leak and be prepared to take swift action.</span></p> <p dir="ltr" style="line-height: 1.38; margin-top: 14pt; margin-bottom: 4pt;"><span style="font-size: 13pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: bold; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">Health Hazards</span></p> <p dir="ltr" style="line-height: 1.38; margin-top: 12pt; margin-bottom: 12pt;"><span style="font-size: 11pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">The primary danger of an unnoticed gas leak is its potential health impacts. Being exposed to leaking gas—from devices like stoves, heaters, or your gas water heater—can induce an array of symptoms, including <a href="https://www.oversixty.com.au/health/body/6-ways-to-combat-headaches-without-painkillers" target="_blank" rel="noopener">headaches</a>, dizziness, nausea, and weariness. These minor symptoms could potentially worsen to more critical health conditions, such as breathing difficulties, memory impairment, and in severe situations, unconsciousness.</span></p> <p dir="ltr" style="line-height: 1.38; margin-top: 12pt; margin-bottom: 12pt;"><span style="font-size: 11pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">Furthermore, carbon monoxide, an invisible and odourless hazardous gas that occurs from malfunctioning gas or electrical appliances, can lead to carbon monoxide poisoning. This condition can display symptoms resembling flu but can escalate to chronic neurological impairment or even prove fatal in the long run.</span></p> <p dir="ltr" style="line-height: 1.38; margin-top: 14pt; margin-bottom: 4pt;"><span style="font-size: 13pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: bold; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">Fire or Explosion Risk</span></p> <p dir="ltr" style="line-height: 1.38; margin-top: 12pt; margin-bottom: 12pt;"><span style="font-size: 11pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">A more immediate danger of an unnoticed gas leak is the potential for a fire or explosion. When the concentration of leaked gas in the air reaches a threshold level, even the smallest spark or open flame can ignite it. This might result from someone lighting a match or a cigarette lighter or inadvertently switching on an electrical device near the gas leak source.</span></p> <p dir="ltr" style="line-height: 1.38; margin-top: 12pt; margin-bottom: 12pt;"><span style="font-size: 11pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">Consequently, the ignited gas can cause a destructive fire or explosion, leading to significant property damage, serious injuries, or fatalities.</span></p> <p dir="ltr" style="line-height: 1.38; margin-top: 14pt; margin-bottom: 4pt;"><span style="font-size: 13pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: bold; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">Environmental Impact</span></p> <p dir="ltr" style="line-height: 1.38; margin-top: 12pt; margin-bottom: 12pt;"><span style="font-size: 11pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">Say, for example, your outdoor gas metre is damaged or the gas pipes buried in your garden develop leaks. The escaped gas can cause harm to your plants and lawn, creating dead patches of grass, discoloured vegetation, or stunted growth. Furthermore, prolonged leaking of natural gas can contribute to greenhouse gas emissions, aggravating the issues of air pollution and climate change.</span></p> <p dir="ltr" style="line-height: 1.38; margin-top: 18pt; margin-bottom: 4pt;"><span style="font-size: 17pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: bold; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">Call in the Experts: Licensed Gas Fitter</span></p> <p dir="ltr" style="line-height: 1.38; margin-top: 12pt; margin-bottom: 12pt;"><span style="font-size: 11pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">When it comes to gas leaks, it's critical not to mess with things you're not licensed to handle. In Adelaide, turn to a licensed gas fitter for gas leak repairs. Your gas fitter is trained in gas leak detection and repair gas leaks to ensure the safety of your home.</span></p> <p dir="ltr" style="line-height: 1.38; margin-top: 12pt; margin-bottom: 12pt;"><img src="https://oversixtydev.blob.core.windows.net/media/2023/12/GasLeaks04.jpg" alt="" width="1280" height="720" /></p> <p dir="ltr" style="line-height: 1.38; margin-top: 12pt; margin-bottom: 12pt;"><span style="font-size: 11pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">Further, regular inspections and proper installation of gas appliances can prevent gas leaks in the first place. If you've been regularly revamping your home with advanced gas installations and didn't already know this, well, you've been living under a rock, mate.</span></p> <p dir="ltr" style="line-height: 1.38; margin-top: 12pt; margin-bottom: 12pt;"><span style="font-size: 11pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">Proactive steps in your gas supply system, like the installation of carbon monoxide detectors and reviewing your gas metre's location, can help identify potential leaks and prevent dangerous carbon monoxide poisoning, exhibiting your perfect gumption.</span></p> <p dir="ltr" style="line-height: 1.38; margin-top: 18pt; margin-bottom: 4pt;"><span style="font-size: 17pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: bold; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">Wrapping Up</span></p> <p dir="ltr" style="line-height: 1.38; margin-top: 12pt; margin-bottom: 12pt;"><span style="font-size: 11pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">As part of the Adelaide community, it's essential to be aware of the potential hazards that household gas leaks can introduce into our homes. A gas leak can spell disaster, from health risks to damage to our property. Being alert for the signs and knowing when to call in the professionals is our best defence against these leaks.</span></p> <p dir="ltr" style="line-height: 1.38; margin-top: 12pt; margin-bottom: 12pt;"><span style="font-size: 11pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">Secure your home from gas leaks with trusted </span><a style="text-decoration: none;" href="https://cyberairconditioning.com.au/locations/sa/air-conditioning-adelaide/"><span style="font-size: 11pt; font-family: Arial,sans-serif; color: #1155cc; background-color: transparent; font-weight: bold; font-style: normal; font-variant: normal; text-decoration: underline; -webkit-text-decoration-skip: none; text-decoration-skip-ink: none; vertical-align: baseline; white-space: pre-wrap;">Air Conditioning Services in Adelaide</span></a><span style="font-size: 11pt; font-family: Arial,sans-serif; color: #000000; background-color: transparent; font-weight: 400; font-style: normal; font-variant: normal; text-decoration: none; vertical-align: baseline; white-space: pre-wrap;">. Remember, it's always better to have a professional tend to leaks or complications with your plumbing gas system, rather than trying to be a hero and tackling it yourself.

<p><a href="https://theconversation.com/profiles/trivess-moore-12580">Trivess Moore</a>, <em><a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a></em>; <a href="https://theconversation.com/profiles/alan-pears-52">Alan Pears</a>, <em><a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a></em>, and <a href="https://theconversation.com/profiles/nicola-willand-441807">Nicola Willand</a>, <em><a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a></em></p> <p>Burning gas in our homes to cook food or heat air and water has become a contentious issue. Gas is an expensive, polluting fossil fuel, and there’s mounting evidence to suggest it’s also <a href="https://www1.racgp.org.au/ajgp/2022/december/health-risks-from-indoor-gas-appliances">bad for our health</a>.</p> <p>Five million existing Australian households will need to <a href="https://grattan.edu.au/report/getting-off-gas/">get off gas</a> within the next 30 years. But for homeowners, the upfront cost can be a major barrier to action. Renters rarely get a say over the appliances installed in their homes. And apartment owners can struggle to make individual changes too.</p> <p>In most cases it’s worth making the switch, for the energy bill savings alone. For example, analysis suggests a household in Melbourne switching from gas to electricity can save <a href="https://theconversation.com/all-electric-homes-are-better-for-your-hip-pocket-and-the-planet-heres-how-governments-can-help-us-get-off-gas-207409">up to A$13,900</a> over a decade.</p> <p>If you’re contemplating upgrading gas appliances in your home, or even disconnecting from the gas network altogether, here are a few handy tips and resources to cut through the confusion.</p> <figure><iframe src="https://www.youtube.com/embed/2JuZgXz6zNo?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption><span class="caption">Homes must switch away from gas by 2050, says policy think tank (ABC News)</span></figcaption></figure> <h2>Tip 1 – Find trusted, independent information</h2> <p>There is no shortage of information on how to make the switch from gas to all-electric appliances. The challenge is finding <a href="https://theconversation.com/we-need-a-lemon-law-to-make-all-the-homes-we-buy-and-rent-more-energy-efficient-204369">trusted and independent information</a>.</p> <p>Not-for-profit organisation <a href="https://renew.org.au/">Renew</a> has compiled a range of <a href="https://renew.org.au/resources/how-we-can-help/efficient-electric-homes/how-we-can-help-going-off-gas/">presentations, guides, case studies and research</a>. <a href="https://www.choice.com.au/">Choice</a> provides independent reviews of household appliances, including operating costs. The Australian government’s <a href="https://www.energyrating.gov.au/">Energy Rating website</a> provides information on appliances to help consumers compare performance. Some <a href="https://www.yarracity.vic.gov.au/services/take-climate-action">local councils</a> and <a href="https://totallyrenewableyack.org.au/">community groups</a> also provide information, support and bulk-buying schemes.</p> <p>You could also visit some of the all-electric homes open to the public for <a href="https://sustainablehouseday.com/">Sustainable House Day</a>. This can help you learn what works from people who have already made the change.</p> <p>The <a href="https://www.facebook.com/groups/MyEfficientElectricHome">My Efficient Electric Home</a> group on Facebook is another active and helpful forum.</p> <p>If you are going all-electric as part of a wider retrofit, consider an independent <a href="https://www.homescorecard.gov.au/">Residential Efficiency Scorecard assessment</a>. This will help you understand what to else you can do to maximise <a href="https://theconversation.com/the-other-99-retrofitting-is-the-key-to-putting-more-australians-into-eco-homes-91231">thermal comfort, environmental benefits and financial outcomes</a>.</p> <h2>Tip 2 – Plan your approach</h2> <p>Once you understand what to do, the next step is planning how to go about it. Think about what is most important to your household. What is driving the change? If it’s your health, you might like to start by eliminating indoor air pollution from the gas stove. Or if you want to save money, start using reverse-cycle air conditioning to heat your home, rather than gas.</p> <p>There are three main ways to go all-electric:</p> <ul> <li> <p><strong>Replace all your gas appliances at once</strong>. Making the change quickly minimises disruption to your home. You may save money on installation costs by doing everything in one go. You will avoid ongoing fixed gas supply charges once you disconnect from the gas network, but you may be required to pay an “<a href="https://energy.act.gov.au/switching-off-your-gas-connection/">abolishment fee</a>” for permanent disconnection. That fee can vary significantly, depending on your location and gas provider. Costs <a href="https://www.smh.com.au/environment/sustainability/would-you-pay-1000-to-get-off-gas-consumer-dismay-over-disconnection-cost-20230223-p5cmw9.html">could be up to $1000 (or more)</a> but some states like Victoria have capped the price a <a href="https://reneweconomy.com.au/fossil-gas-death-spiral-regulator-sets-exit-fee-to-socialise-cost-of-mass-disconnection/">household can be charged at $220</a>. Renters wouldn’t be able to permanently disconnect without permission from the landlord, so they would still be open to paying the daily connection fee even if they found alternative electric options for everything else.</p> </li> <li> <p><strong>Replace your gas appliances one at a time</strong>, as finances allow. However, there will come a point where <a href="http://www.ata.org.au/wp-content/projects/CAP_Gas_Research_Final_Report_251114_v2.0.pdf">financially you will be better off</a> replacing all the remaining gas appliances. This is largely because it will not be affordable to keep paying the daily connection cost for gas if you just have one gas appliance remaining.</p> </li> <li> <p><strong>Just stop using gas appliances</strong> in favour of existing electric appliances that do the same job, such as a <a href="https://reneweconomy.com.au/the-traps-laid-by-the-fossil-gas-industry-for-uninformed-households/">reverse cycle air conditioner for space heating</a>. You may have – or can buy – plug-in electric alternatives, such as a microwave ovens, portable induction cooktops, air fryers and heaters. These can be a good option for renters when landlords won’t make changes.</p> </li> </ul> <p>You could even borrow portable appliances to see how they work before committing to buying your own.</p> <figure><iframe src="https://www.youtube.com/embed/tLjWZicC4mE?wmode=transparent&amp;start=2" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption><span class="caption">Households share their electrification journey (Renew)</span></figcaption></figure> <h2>Tip 3 – Access available rebates and resources</h2> <p>Most states offer various rebates for households to reduce the upfront cost of replacing gas appliances. These could reduce costs by thousands of dollars. Some rebates also target rental housing. Here is a list of key rebates available in different states:</p> <ul> <li><a href="https://www.epw.qld.gov.au/about/initiatives/household-energy-savings-program">Queensland</a></li> <li><a href="https://www.energy.nsw.gov.au/households/rebates-grants-and-schemes">New South Wales</a></li> <li><a href="https://www.climatechoices.act.gov.au/policy-programs/home-energy-support-rebates-for-homeowners">ACT</a></li> <li><a href="https://www.energy.vic.gov.au/for-households/victorian-energy-upgrades-for-households">Victoria</a></li> <li><a href="https://recfit.tas.gov.au/household_energy/energy_saver_loan_scheme">Tasmania</a></li> <li><a href="https://www.sa.gov.au/topics/energy-and-environment/using-saving-energy/retailer-energy-productivity-scheme">South Australia</a></li> </ul> <p>Some not-for-profit organisations (such as the <a href="https://www.bsl.org.au/services/energy-assistance/">Brotherhood of St Laurence</a>) offer financial and other support for lower-income households struggling to pay their energy bills.</p> <h2>Tip 4 – Wait for a sale or negotiate a better deal</h2> <p>It might sound simple but you can always save money by waiting until these electric appliances are on sale. If you are buying multiple appliances you can try to negotiate a better price. Factory seconds outlets offer lower prices as well.</p> <h2>Tip 5 – Know the issues</h2> <p>While the shift to all-electric will likely provide many benefits there are some things you need to consider:</p> <ul> <li>The carbon emissions from electricity are falling fast, and many homes have rooftop solar. Combining <a href="https://grattan.edu.au/report/getting-off-gas/">all-electric with solar panels</a> will maximise returns.</li> <li>You may have to adjust to how new technologies operate and perform. For example, you may need <a href="https://www.theage.com.au/goodfood/tips-and-advice/do-you-really-have-to-buy-new-cookware-all-your-burning-questions-about-induction-cooking-answered-20230810-p5dvd0.html">new, metallic cookware for an induction cooktop</a> and become familiar with their fast response. Additionally, some people find heat from reverse cycle air conditioners to be drier and/or draughtier than gas heating. Floor-mounted units heat more effectively.</li> <li>It is not just the energy performance of appliances that matters. For example, noise from heat pump hot water services can vary across different brands. They can also require more space for installation.</li> <li>Undertaking a wider energy retrofit (for example, increasing insulation in walls, ceiling and underfloor, upgrading windows to double glazing) may mean you can buy a smaller, cheaper reverse cycle air conditioner when replacing gas heating.</li> <li>Electric appliances also need maintenance to make sure they perform optimally. For example, reverse cycle air conditioners have filters that must be regularly cleaned. While this can be done by households, it can be hard for people with mobility issues.</li> <li>Depending on the capacity of your electricity switchboard or wiring, extra electric appliances may require upgrades.</li> <li>For renters, while you could use portable appliances, you may not be able to disconnect from gas completely, meaning you would still have to pay a daily connection fee.</li> <li>Gas and electricity prices can change over time, for many reasons. For example, if fixed gas distribution costs are spread over fewer customers.</li> </ul> <h2>A worthwhile investment</h2> <p>Australian states and territories have started banning gas in new builds. Victoria and the ACT will soon require <a href="https://theconversation.com/cooking-and-heating-without-gas-what-are-the-impacts-of-shifting-to-all-electric-homes-210649">new housing and major renovations to be all-electric</a>. Others are likely to follow.</p> <p>For people in existing housing around Australia, it can be daunting to make the switch. Many of us have grown up with gas in our homes and when one appliance breaks, the easiest thing to do is replace like-for-like. But the weight of evidence shows it’s worth taking the time to look at the alteratives and invest in upgrading to all-electric appliances. The benefits far outweigh the costs. <!-- Below is The Conversation's page counter tag.

Unseen photo of Dan Andrews slammed after gas ban fury

<p>Dan Andrews has come under fire after a photo emerged of him cooking on a gas stove, just weeks after announcing a state-wide ban on natural gas in new homes. </p> <p>The Victorian premier has been slated online after Liberal MP for Mornington Chris Crewther shared a photo of Mr Andrews cooking on a gas stove inside his home during Covid-19 lockdown in April 2020.</p> <p>“I agree with what Dan does: cooking with gas. It’s much better!” the Liberal MP wrote alongside the photo.</p> <p>“But I don’t agree with what Dan says: banning gas cooking in new homes from next year. Future cooking quality is going to go downhill!”</p> <p><iframe style="border: none; overflow: hidden;" src="https://www.facebook.com/plugins/post.php?href=https%3A%2F%2Fwww.facebook.com%2FCrewtherChris%2Fposts%2Fpfbid0cbvPq9wQyCJXLcfBXyPj9fucoxTvNUiaRnTYXtS35m3G1xmSPaGcyWqgGu1Q6rcJl&show_text=true&width=500" width="500" height="658" frameborder="0" scrolling="no" allowfullscreen="allowfullscreen"></iframe></p> <p>Angry Victorians were quick to slam the premier in the comments of the photo, which has racked up over 6,000 comments. </p> <p>One person on Facebook said it was “proof we are truly living in a socialist dictatorship”.</p> <p>Another described Mr Andrews as a “menace”, while someone else asked “Why can’t we just have a Dan ban?”</p> <p>Slamming the new initiative, one commented wrote that “homeowners should be free to have the choice of gas or electricity”.</p> <p>The photo comes just weeks after Dan Andrews announced that from January 1st 2024, no new homes or residential subdivisions requiring a planning permit in Victoria would be connected to gas. </p> <p>The state government is dubbing the move as a measure to reduce cost of living pressures, claiming households will save up to $1,000 off their annual energy bills while reducing household emissions.</p> <p>The all-electric requirement would also apply to all new government buildings which have not yet reached design stage, including schools, hospitals, police stations and public housing.</p> <p>Despite the public backlash of the initiative, the Energy Efficiency Council applauded the decision.</p> <p>CEO Luke Menzel said “all-electric homes are all-good for Victorian families. They are cheaper to run, healthier to live in, and help lower emissions.”</p> <p>“Given the upfront costs of building an all-electric home are comparable to building a home with a gas connection, that makes going all-electric a no-brainer,’’ he said.</p> <p><em>Image credits: Facebook / Getty Images</em></p>

Cooking (and heating) without gas: what are the impacts of shifting to all-electric homes?

<p><em><a href="https://theconversation.com/profiles/trivess-moore-12580">Trivess Moore</a>, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a>; <a href="https://theconversation.com/profiles/alan-pears-52">Alan Pears</a>, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a>, and <a href="https://theconversation.com/profiles/joe-hurley-157161">Joe Hurley</a>, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a></em></p> <p>Gas connections for all new housing and sub-divisions will be <a href="https://www.premier.vic.gov.au/new-victorian-homes-go-all-electric-2024">banned in Victoria</a> from January 1 next year. The long-term result of the state government’s significant change to planning approvals will be all-electric housing. The ACT made <a href="https://www.climatechoices.act.gov.au/policy-programs/preventing-new-gas-network-connections">similar changes</a> early this year, in line with a shift away from gas across <a href="https://www.bbc.com/news/science-environment-47559920">Europe</a> and <a href="https://www.theguardian.com/environment/2023/jan/19/gas-stove-culture-war-united-states">other locations</a>, although the NSW Premier Chris Minns has <a href="https://www.theguardian.com/australia-news/2023/jul/31/nsw-wont-ban-gas-in-new-homes-as-premier-declares-i-dont-need-another-complication">baulked</a> at doing the same.</p> <p>Around <a href="https://www.energy.vic.gov.au/renewable-energy/victorias-gas-substitution-roadmap">80% of homes</a> in Victoria are connected to gas. This high uptake was driven by gas being seen as more affordable and sustainable than electricity over past decades. The situation has <a href="https://www.iea.org/events/net-zero-by-2050-a-roadmap-for-the-global-energy-system">changed dramatically</a> as renewable electricity generation increases and <a href="https://www.abc.net.au/news/2023-07-27/aemo-wholesale-electricity-prices-fall-impact-power-bills/102654498">costs fall</a>.</p> <p><a href="https://theconversation.com/all-electric-homes-are-better-for-your-hip-pocket-and-the-planet-heres-how-governments-can-help-us-get-off-gas-207409">Research</a> has suggested for more than a decade that the benefits of all-electric homes <a href="https://bze.org.au/research_release/energy-efficient-buildings-plan/">stack up in many locations</a>. New homes built under mandatory building energy performance standards (increasing from <a href="https://thefifthestate.com.au/innovation/building-construction/victoria-kicks-the-can-down-the-road-again-on-the-national-construction-code/">6 to 7 stars</a> in Victoria in May 2024) need smaller, cheaper heating and cooling systems. Installing reverse-cycle air conditioning for cooling provides a cost-effective heater as a bonus.</p> <p>Savings from not requiring gas pipes, appliances and gas supply infrastructure help to offset the costs of highly efficient electric appliances. Mandating fully electric homes means economies of scale will further reduce costs.</p> <h2>How does this ban help?</h2> <p>To achieve environmentally sustainable development, reforms of planning policy and regulation <a href="https://theconversation.com/sustainable-cities-australias-building-and-planning-rules-stand-in-the-way-of-getting-there-84263">are essential</a> to convert innovation and best practice to mainstream practice. Planning policy is particularly important for apartment buildings and other housing that may be rented or have an owners’ corporation. Retrofits to improve energy efficiency can be difficult in these situations.</p> <p>Banning gas in new and renovated housing will <a href="https://grattan.edu.au/report/getting-off-gas/">cut greenhouse gas emissions</a>. It’s also <a href="https://theconversation.com/gas-cooking-is-associated-with-worsening-asthma-in-kids-but-proper-ventilation-helps-151591">healthier for households</a> and <a href="https://www.sustainability.vic.gov.au/research-data-and-insights/research/research-reports/the-victorian-healthy-homes-program-research-findings">reduces healthcare costs</a> as well as <a href="https://grattan.edu.au/report/getting-off-gas/">energy bills and infrastructure costs</a>. The Victorian government suggests the change will save all-electric households <a href="https://www.premier.vic.gov.au/new-victorian-homes-go-all-electric-2024">about $1,000 a year</a>. Houses with solar will be even better off.</p> <p>The government appears to be offering wide support to ensure these changes happen, but this will need to be monitored closely.</p> <p>Some households will face extra costs for electric appliances and solar panels. The government’s announcement of <a href="https://www.premier.vic.gov.au/new-victorian-homes-go-all-electric-2024">$10 million</a> for Residential Electrification Grants should help with some of these costs while the industry adjusts.</p> <p>There will be impacts and benefits for the local economy. Some jobs may be lost, particularly in the gas appliance and plumbing industry. The government has announced financial support to retrain people and they will still have essential roles in the existing housing sector.</p> <p>Many gas appliances are imported, including ovens, cooktops and instantaneous gas water heaters. Some components of efficient electric products, such as hot water storage tanks, are made locally. Local activities, including distribution, sales, design, installation and maintenance, comprise much of the overall cost.</p> <h2>Challenges of change must be managed</h2> <p>Sustainability benefits will depend on what <a href="https://grattan.edu.au/report/getting-off-gas/">happens with the energy network</a>. We need more renewable energy, energy storage and smarter management of electricity demand.</p> <p>The shift to all-electric homes may mean winter peak demand for heating increases. Energy market operators and governments will have to monitor demand changes carefully to avoid the reliability issues we already see in summer. However, improving energy efficiency, energy storage and demand management will help reduce this load (and household costs).</p> <p>While the benefits are clear for new homes, the changes may <a href="https://www.bsl.org.au/research/publications/enabling-electrification/">increase gas costs and energy poverty</a> for residents of existing housing who don’t shift to efficient electric solutions. The government has reconfirmed financial rebates to help households switch from gas.</p> <p>In addition, existing housing may face building quality and performance issues. Some may require electrical wiring upgrades as part of the transition.</p> <p>Social acceptance of some electric appliances may also be an issue. For example, <a href="https://www.rmit.edu.au/about/schools-colleges/property-construction-and-project-management/research/research-centres-and-groups/sustainable-building-innovation-laboratory/projects/heet-housing-energy-efficiency-transitions">our research</a> has found some households dislike the way heating from reverse cycle air conditioners feels. Others do not like cooking on induction cooktops.</p> <p>Consumer education and modifications to appliances and buildings may be needed to increase acceptance and avoid backlash.</p> <p>Some electric appliances are available overseas but not in Australia. Higher demand may increase the range of imports. For example, floor-mounted heat pumps can make heating feel similar to gas heating while still providing effective cooling.</p> <p>We should not assume electric appliances are all equal. To improve consumer protection, action is needed on weak standards and limited and inconsistent public information. For example, information on noise levels and efficiency under a range of weather conditions must be standardised.</p> <p>Moving housing away from gas is an <a href="https://link.springer.com/book/10.1007/978-981-99-2760-9">important step</a> in the transition to a zero-carbon economy and energy system. Careful management is needed to ensure this transition is effective, accepted and fair.</p> <p>Continued planning reforms are also essential to ensure environmentally sustainable development of housing and communities. Other urgent priorities include urban cooling and greening, and <a href="https://theconversation.com/turning-the-housing-crisis-around-how-a-circular-economy-can-give-us-affordable-sustainable-homes-208745">circular economy approaches</a> to reduce the material and waste impacts of housing and thus the carbon that goes into building and running homes.<!-- Below is The Conversation's page counter tag.

Keen to get off gas in your home, but struggling to make the switch? Research shows you’re not alone

<p><em><a href="https://theconversation.com/profiles/sangeetha-chandrashekeran-330214">Sangeetha Chandrashekeran</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> and <a href="https://theconversation.com/profiles/julia-de-bruyn-1250694">Julia de Bruyn</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a></em></p> <p>More than five million households in Australia are connected to the gas network. Tackling climate change requires homes and businesses to move away from gas, and instead embrace electric appliances as the power grid shifts to renewable energy.</p> <p>People can <a href="https://grattan.edu.au/wp-content/uploads/2023/06/Getting-off-gas-why-how-and-who-should-pay.pdf">save</a> considerable money by switching away from gas – even more so if they have solar panels installed. But still, millions of Australians haven’t yet made the move. Why?</p> <p>Our new research, <a href="https://www.bsl.org.au/research/publications/enabling-electrification/">released today</a>, seeks to shed light on this question. We focused on lower-income households in Victoria and found while most participants supported the transition from gas, few owned electric appliances for heating, cooking and hot water.</p> <p>There were two main barriers: people couldn’t afford the upfront cost of buying new electric appliances, or were renting and so had little or no say over what appliances were installed. Overcoming these and other challenges is crucial to ensure no-one gets left behind in Australia’s energy transition.</p> <h2>Making it fair for all</h2> <p>Victoria has <a href="https://www.climatechange.vic.gov.au/climate-action-targets">committed</a> to net-zero greenhouse gas emissions by 2045. To help achieve this, the state government is developing a <a href="https://www.energy.vic.gov.au/renewable-energy/victorias-gas-substitution-roadmap">plan</a> for the state to electrify.

This is despite those households using less energy.</p> <p>The affordability of gas will become worse as more households electrify. That’s because part of a gas bill includes the fixed cost of running gas infrastructure – so as progressively fewer people use gas, the remaining users pay more.</p> <p>And those who don’t make the move away from gas miss out on the long-term economic benefits. <a href="https://www.energy.vic.gov.au/__data/assets/pdf_file/0039/579882/Victorias-Gas-Substitution-Roadmap-Embracing-electricity-to-cut-your-bills-at-home.pdf">Analysis</a> last year suggested a typical Victorian household could reduce its annual energy costs by A$1,020 by replacing gas heating, cooking and hot water systems with electric ones. The figure rises to $1,250 for those with solar power. These savings will be amplified if the price of gas continues to rise relative to electricity.</p> <p>That’s why it’s important to help as many lower-income people as possible to make the switch to electric appliances. Our research set out to understand what might prevent or enable that shift.</p> <p>We studied households in Victoria: the state with the highest prevalence of residential gas use in Australia and where plans for an economy-wide transition away from fossil gas are underway.</p> <h2>What we found</h2> <p>We conducted an online survey, which received 220 eligible responses. We also undertook focus groups with 34 people. All participants were from lower-income households.</p> <p>Most participants – 88% – used gas in the home, reflecting its prevalence in Victoria.</p> <p>More than two-thirds indicated some level of support for a transition away from household gas to cleaner energy sources. Support was greater with higher levels of education. There was no significant difference based on financial stress, housing tenure, location or age.</p> <p>But this support had not translated into action. Just one in ten surveyed households had replaced gas appliances with electric ones within the past five years. Among those who had switched or planned to switch, the main reasons were lower running costs and environmental benefits.</p> <p>Respondents considered electric appliances to be safer and better for the environment. Gas appliances were considered better for heating and cooking. Many respondents were unsure about the relative benefits of electric versus gas appliances when it came to cost, reliability, safety and the environment.</p> <figure class="align-center "><img src="https://images.theconversation.com/files/538548/original/file-20230720-15-61nj78.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/538548/original/file-20230720-15-61nj78.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=175&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/538548/original/file-20230720-15-61nj78.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=175&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/538548/original/file-20230720-15-61nj78.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=175&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/538548/original/file-20230720-15-61nj78.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=221&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/538548/original/file-20230720-15-61nj78.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=221&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/538548/original/file-20230720-15-61nj78.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=221&amp;fit=crop&amp;dpr=3 2262w" alt="" /><figcaption><span class="caption">Graph showing the benefits of gas versus electric appliances, as perceived by participants in the study.</span> <span class="attribution"><span class="license">Author provided</span></span></figcaption></figure> <p>Preferences were strongly linked to what people were currently using.

And lower-income households, as well as others facing barriers to getting off gas, must be included when planning the transition.</p> <p><em>Researchers David Bryant and Damian Sullivan from the Brotherhood of St Laurence contributed to this article and co-authored the research upon which it is based.<!-- Below is The Conversation's page counter tag.

All-electric homes are better for your hip pocket and the planet. Here’s how governments can help us get off gas

<p><a href="https://theconversation.com/profiles/esther-suckling-1220357">Esther Suckling</a>, <em><a href="https://theconversation.com/institutions/grattan-institute-1168">Grattan Institute</a></em></p> <p>If every Australian household that uses gas went all-electric today, we would “save” more than 30 million tonnes of carbon dioxide emissions over the next ten years. That’s because there are more than <a href="https://www.energynetworks.com.au/resources/fact-sheets/reliable-and-clean-gas-for-australian-homes-2/">5 million households</a> on the gas network, and the <a href="https://grattan.edu.au/report/getting-off-gas">avoided emissions per home</a> ranges from 5-25 tonnes over the coming decade, depending on the location.</p> <p>Most people would spend less money on energy too. Electric appliances use less energy than gas appliances to do the same job, making them cheaper to run.</p> <p>Our <a href="https://grattan.edu.au/report/getting-off-gas">new report</a> shows how much most households can save by switching from gas to electricity for heating, hot water and cooking. The extra cash couldn’t come at a better time: about <a href="https://www.rmit.edu.au/news/all-news/2023/may/hidden-energy-poverty">a quarter of Australian households</a> say they found it difficult to pay their energy bills this year.</p> <p>But many households face hurdles that stop them, or make it hard for them, to go all-electric.

It’s a flat $3,890 figure for Brisbane, rather than a range, because there’s no gas heating.</span> <span class="attribution"><span class="source">Grattan Institute</span>, <span class="license">Author provided</span></span></figcaption></figure> <p>Households in Melbourne tend to use more gas than those in other mainland capitals, mainly because the winter is so cold. Our report found Melburnians who replace broken gas appliances with electric ones, or move into an all-electric home, could save up to A$13,900 over ten years. Households with rooftop solar will save even more.</p> <p>It’s a similar story in most parts of Australia except the west, where gas is relatively cheap. This mainly reflects differences in the historical development of the gas markets between the west and east coasts.</p> <p>Getting off gas could also be <a href="https://www1.racgp.org.au/ajgp/2022/december/health-risks-from-indoor-gas-appliances">good for your health</a>. Several studies link cooking with gas to <a href="https://www.nationalasthma.org.au/living-with-asthma/resources/patients-carers/factsheets/gas-stoves-and-asthma-in-children">childhood asthma</a>.</p> <p> </p> <h2>Households face a series of hurdles</h2> <p>Renters make up nearly a third of all households, and they have little or no control over the appliances that are installed. As most electric appliances cost more to buy than gas ones – and the subsequent bill savings flow to tenants – landlords have little incentive to upgrade their properties from gas to all-electric.</p> <p>Apartment living can increase the level of complexity. Multi-unit dwellings often bundle gas bills into body-corporate fees, limiting the occupants’ incentive to go all-electric. There can also be space constraints in these buildings. Centralised electric heat pumps, for example, take up more space than centralised gas water heaters.</p> <p>Then there are households that simply can’t afford the upgrade. Induction stoves and heat pumps are more expensive than their gas equivalents, by up to a combined $2,000. This initial outlay will soon be recovered by cheaper energy bills, but that doesn’t help households that don’t have the cash up front. The <a href="https://melbourneinstitute.unimelb.edu.au/data/taking-the-pulse-of-the-nation-2022/2023/energy-poverty">12% of households that skipped meals</a> to pay their energy bills in the past year are the most likely to remain locked into high gas bills.</p> <p>Some people also simply prefer cooking with gas. Some think induction cooktops will be no better than the poor-performing electric cooktops they may have used in the distant past. Others haven’t ever heard of a heat pump for hot water.</p> <h2>Here’s how governments can help</h2> <p>Governments, both state and federal, should lower the hurdles on the path to all-electric homes -– to reduce people’s cost of living and to cut carbon emissions.</p> <p>As a first step, state governments should ban new gas connections to homes. In 2021, more than 70,000 households joined the gas network. Trying to shift households off gas while allowing new connections is like pouring water into a bucket with a hole.</p> <p>Then, governments should provide landlords with tax write-offs on new induction stoves and heat pumps for hot water, for a limited time. After that, they should require every rental property to be all-electric. Governments should pay to upgrade public housing to all-electric, where they are the landlords. And they should pay not-for-profits managing community housing to do the same.</p> <p>The federal government should help all households to spread the cost of electric appliances over time. It should subsidise banks to offer low-interest loans for home electrification, via the Clean Energy Finance Corporation.</p> <p>And governments should set out to change people’s preferences, from gas to electric. They should embark on a multi-decade communication campaign, not unlike the campaign to upgrade from analogue to digital television in the early 2000s.</p> <p>A key challenge will be shifting people’s ideas about the best way to cook. There are precedents. In Gininderry, a new all-electric suburb of Canberra, one developer recruited chefs to run demonstrations on induction cooktops at the display village. The proportion of potential homebuyers <a href="https://ginninderry.com/wp-content/uploads/2021/08/Ginninderry-2017-Householder-Attitudes-to-Residential-Renewable-Energy-Futures.pdf">willing to consider buying an all-electric home</a> rose from 67% to 88%.</p> <figure><iframe src="https://www.youtube.com/embed/K9ytSh5TM9M?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption><span class="caption">Induction cooking with Chef David Wei at Ginninderry.</span></figcaption></figure> <h2>‘Green gas’ is no panacea: electricity is cheaper</h2> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/532117/original/file-20230615-23-n0wdqe.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/532117/original/file-20230615-23-n0wdqe.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/532117/original/file-20230615-23-n0wdqe.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=572&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/532117/original/file-20230615-23-n0wdqe.png?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=572&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/532117/original/file-20230615-23-n0wdqe.png?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=572&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/532117/original/file-20230615-23-n0wdqe.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=719&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/532117/original/file-20230615-23-n0wdqe.png?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=719&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/532117/original/file-20230615-23-n0wdqe.png?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=719&amp;fit=crop&amp;dpr=3 2262w" alt="Chart comparing the cost of hydrogen to electricity over time, showing hydrogen is more expensive and will remain so for decades" /></a><figcaption><span class="caption">Hydrogen is more expensive than electricity and will remain so for decades.</span> <span class="attribution"><span class="source">Grattan Institute</span>, <span class="license">Author provided</span></span></figcaption></figure> <p>The gas industry has another solution in mind: instead of switching from gas to electricity, it suggests using “green gas” -– biomethane or “green” hydrogen. Biomethane is chemically identical to natural gas, but is derived from biological materials such as food waste, sewage or agricultural waste. Green hydrogen is made by using electricity to split water into hydrogen and oxygen.</p> <p>But both options are <a href="https://theconversation.com/hydrogen-where-is-low-carbon-fuel-most-useful-for-decarbonisation-147696">too expensive and too far away</a>. Under the most generous of assumptions, green hydrogen will only become cost-competitive with electricity after 2045. And there is not enough biomethane commercially available to replace gas in households.</p> <p>Meanwhile, more than three million Australian homes already run on electricity alone.</p> <p>Getting the five million homes that use gas to the same point won’t be easy. But with good policy, it is doable. For households, and the climate, there is much to be gained.<!-- Below is The Conversation's page counter tag.

Want an easy $400 a year? Ditch the gas heater in your home for an electric split system

<p>Earlier this month, regulators <a href="https://theconversation.com/why-are-electricity-prices-going-up-again-and-will-it-ever-end-201869">flagged</a> power price rises in Queensland, New South Wales, Victoria and South Australia. Like many people, you’re probably wondering how you can minimise the financial pain.</p> <p>Getting rid of gas and electrifying everything in your home can save you money. <a href="https://renew.org.au/wp-content/uploads/2022/11/Report-Limiting-energy-bills-by-getting-off-gas.pdf">Modelling</a> by not-for-profit organisation Renew showed annual bills last year for a <a href="https://www.nathers.gov.au/owners-and-builders/home-energy-star-ratings">seven-star</a> all-electric home with solar power were between 69% (Western Sydney) and 83% (Hobart) cheaper than bills for a three-star home with gas appliances and no solar. </p> <p>There are other reasons to kick the gas habit, too. As renewables form an ever-growing part of Australia’s energy mix, electrifying the home increasingly helps tackle climate change. What’s more, there are sound <a href="https://www.unsw.edu.au/news/2023/02/a-heated-debate--how-safe-are-gas-stoves--">health</a> reasons to get rid of gas appliances.</p> <p>But where do you start? And how do you get the best bang for your buck? Here, I offer a few tips.</p> <h2>A quick guide to home energy use</h2> <p>Australian home energy use can be separated into a few categories: </p> <ul> <li>space heating and cooling</li> <li>water heating</li> <li>cooking</li> <li>vehicles </li> <li>other appliances (many of which are largely already electric). </li> </ul> <p>Of the appliances that typically depend on gas, the <a href="https://www.rewiringaustralia.org/report/castles-and-cars-discussion-paper">largest component</a> (37%) is space heating, followed by hot water (24%) and cooking (6%). </p> <p>This varies between states. Victoria, for example, is particularly dependent on gas. </p> <p>But the breakdown above gives some insight into the largest contributors to energy costs in the average Australian home – particularly in the cooler southern regions.</p> <p>While both gas and electricity costs are rising, as they are now in most states, all-electric homes can expect lower overall increases. <a href="https://renew.org.au/wp-content/uploads/2022/11/Report-Limiting-energy-bills-by-getting-off-gas.pdf">Analysis</a> by Renew has shown ditching the old gas heater in favour of a split system/reverse cycle air-conditioner (without solar panels) can lead to average savings of A$546 each year in Canberra, $440 in Adelaide, $409 in Melbourne and $256 in Perth. </p> <p>Heating a space with a reverse-cycle air conditioner is about four times more efficient than using natural gas. And when the electricity is generated by renewables, it can be done with zero greenhouse gas emissions.</p> <p>And what about heating water? Using the existing electricity grid, the cost of using an electric heat pump is around half that of using a natural gas water heater. </p> <p>The costs fall even lower if a household shifts to solar panels subsidised or financed by government, backed by a home battery providing the energy. In this case, heating costs are around a third of using gas.</p> <h2>So what’s the payback?</h2> <p>Buying new appliances costs money. So it’s important to examine the “payback” period - in other words, the length of time it takes for energy bill savings to equal the cost of the initial investment in a new appliance. </p> <p>The payback period can vary depending on:</p> <ul> <li>cost and quality of the appliance</li> <li>an appliance’s energy rating</li> <li>size of the system</li> <li>for space heating, whether a split system is replacing an existing ducted system or being added on externally.</li> </ul> <p>A <a href="https://www.climatecouncil.org.au/wp-content/uploads/2022/10/CC_MVSA0323-CC-Report-Gas-vs-Electricity_V4-Single.pdf">report</a> last year by the Climate Council calculated the approximate cost differences between higher and lower-end electric appliances. Lower-end hot water heat pumps, reverse-cycle air conditioner and induction stoves were priced around $7,818 all together, while higher-end appliances cost around $14,936 together.</p> <p>Both scenarios included installation costs and $3,000 for electrical upgrades and other costs. </p> <p>The payback period for low-priced appliances ranged from five years in Hobart and Canberra to 15 years in Perth and Sydney. Higher-priced appliances were in the order of eight to ten years for most cities and 12, 16 and 19 years for Melbourne, Perth and Sydney respectively.</p> <p>Rolled out at scale, household electrification is also a feasible way to reduce gas demand.

And why look for a technological solution to a problem we already know how to solve?</p> <p>Modelling by <a href="https://environmentvictoria.org.au/wp-content/uploads/2020/06/Vic-Gas-Market-Demand-Side-Study-Final-Report-1.pdf">Environment Victoria</a> has shown installing heat pumps for heating and cooling would reduce statewide gas use by 48 petajoules a year, compared to the relatively minimal 0.5 petajoules saved by installing induction cooktops. </p> <p>At the same scale – and using a similar technology – replacing gas hot water with heat pump hot water reduces household gas use by 10 petajoules each year. That’s an enormous saving of gas.</p> <h2>The bigger picture for all-electric homes</h2> <p>Existing homes can benefit from a combination of electrification, rooftop solar and batteries. They can also benefit from energy efficiency measures such as installing insulation, stopping draughts, closing off rooms and wearing the right clothing for the season.</p> <p>We can work together to speed up the transition to renewable energy and reduce the demand for gas.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://theconversation.com/want-an-easy-400-a-year-ditch-the-gas-heater-in-your-home-for-an-electric-split-system-201941" target="_blank" rel="noopener">The Conversation</a>. </em></p>

Cheaper gas and electricity are within our grasp

<p>Virtually every country in the world is facing a crisis in energy costs, yet while other countries can’t do much about it, Australia can.</p> <p>Australia could get its east coast gas producers to supply the domestic gas market for less than A$10 a gigajoule. Earlier this year, prices were more than $40 a gigajoule, and now sit at $25-30 a gigajoule.</p> <p>Tuesday’s budget factored in retail electricity price rises of <a href="https://images.theconversation.com/files/492030/original/file-20221027-18797-tg4woh.JPG">more than 50%</a> over two years. The increases in retail gas prices exceeded 40%.</p> <p>Outlining the budget on Tuesday, Treasurer Jim Chalmers said any responsible government facing these kinds of price hikes needed to “consider a <a href="https://ministers.treasury.gov.au/ministers/jim-chalmers-2022/transcripts/joint-press-conference-main-committee-room-parliament-house">broader suite of regulatory interventions</a>” than in the past.</p> <p>Chalmers had “more work to do” and would work with the states.</p> <p>Here is the key step I think should be taken.</p> <p><strong>To restrain electricity prices, cut gas prices</strong></p> <p>The quickest way to get electricity prices down is to significantly lower the cost of gas. Gas generators come online after cheaper forms of generation have already been pressed into service, and so help set the final price charged.</p> <p>Getting gas prices below $10 a gigajoule would also help households that are facing crippling gas bills, as well as industries that rely on sensibly priced energy for their existence including Australia’s glass, paper and fertiliser industries.</p> <p>Once those industries close, they are unlikely to return.</p> <p>Here’s what’s been done so far.</p> <p>The Turnbull, Morrison and recently the Albanese governments have each reached agreements with the three liquid natural gas producers operating out of Gladstone in Queensland that together control around 90% of east coast reserves.</p> <p><strong>‘Sufficient supply’ isn’t affordable supply</strong></p> <p>The agreements require the supply of sufficient gas to meet the needs of east coast gas consumers.</p> <p>For a while they worked to reduce then-high domestic prices to sensible levels, because international prices were low. But now international prices have climbed to multiples of usual levels, agreements to supply without specific reference to prices are no longer enough.</p> <p>An agreement to supply “sufficient” quantities of gas at $25-40 per gigajoule is an agreement to not supply much. After industries close, supply will be “sufficient” for the remaining users who can afford it, but it won’t be what we want.</p> <p>We need to get the east coast liquefied natural gas (LNG) producers to supply sufficient gas to the east coast at prices below $10 a gigajoule. They would continue to make a profit at those prices, albeit much less than otherwise.</p> <p>As it happens, the Commonwealth has the power to get such commitments, because it has the power to stop exports. That power gives it complete leverage.</p> <p>We need to be clear on two points.</p> <p>First, there is no suggestion here that the LNG producers’ long-term contracts are at risk. Asian buyers need not be concerned. All three LNG projects were underwritten by long-term contracts at fixed prices.</p> <p>What we are talking about is the gas the three producers have available beyond their need to service these long contracts. This gas can either be exported to the spot, or short-term, market at very high prices or sold domestically.</p> <p>They should be told they can only export gas to the currently lucrative international spot market if they sell sufficient gas domestically to get prices clearly below $10 a gigajoule.</p> <p><strong>Other exporters reserve gas</strong></p> <p>Second, what I am suggesting is akin to what all other gas exporting countries do.</p> <p>Australia has by far the highest domestic gas prices of any gas exporting country. No other country would tolerate its gas being exported while its domestic market is paying the same high prices as international customers.</p> <p>The gas companies need to come to the party, either to earn their “licence to operate” or to avoid the threat of export controls.</p> <p>If they know the threat of export controls is real, I believe they will do what’s necessary without the need to actually control exports.</p> <p>A final point: there can be no argument about “<a href="https://sersolutions.com.au/what-is-sovereign-risk-and-how-does-it-affect-australia/">sovereign risk</a>”, the idea that foreign companies will no longer do business with Australia if it changes the rules.</p> <p>The long-term gas exporting contracts would remain intact. Australia would simply be aligning itself with all other gas exporting nations – and, by the way, with <a href="https://www.wa.gov.au/government/publications/wa-domestic-gas-policy">Western Australia</a>, which has long looked after its residents and businesses by reserving gas to ensure reasonable domestic prices.<!-- Below is The Conversation's page counter tag.

The magnificent Lake Eyre Basin is threatened by 831 oil and gas wells

<p>The heart-shaped Lake Eyre Basin covers about one-sixth of Australia. It contains one of the few remaining pristine river systems in the world.</p> <p>But new research shows oil and gas activity is extending its tentacles into these fragile environments. Its wells, pads, roads and dams threaten to change water flows and pollute this magnificent ecosystem.</p> <p>The <a href="http://www.publish.csiro.au/MF/MF22063" target="_blank" rel="noopener">study</a>, by myself and colleague Amy Walburn, investigated current and future oil and gas production and exploration on the floodplains of the Lake Eyre Basin. We found 831 oil and gas wells across the basin – and this number is set to grow. What’s more, state and Commonwealth legislation has largely failed to control this development.</p> <p>State and national governments are promoting massive gas development to kickstart Australia’s economy. But as we show, this risks significant damage to the Lake Eyre Basin and its rivers.</p> <h2>A precious natural wonder</h2> <p>The Lake Eyre Basin is probably the last major free-flowing river system on Earth – meaning no major dams or irrigation diversions stem the rivers’ flow.</p> <p>This country has been looked after for tens of thousands of year by First Nations people, including the Arrernte, Dieri, Mithaka and Wangkangurru. This care continues today.</p> <p>The biggest rivers feeding the basin – the Diamantina, Georgina and Cooper – originate in western Queensland and flow to South Australia where they pour into Kathi Thanda-Lake Eyre.</p> <p>As they wind south, the rivers dissect deserts and inundate floodplains, lakes and wetlands – including 33 wetlands of national importance.</p> <p>This natural phenomenon has happened for millennia. It supports incredible natural booms of plants, fish and birds, as well as tourism and livestock grazing. But our new research shows oil and gas development threatens this precious natural wonder.</p> <h2>Massive industrial creep</h2> <p>Our <a href="http://www.publish.csiro.au/MF/MF22063" target="_blank" rel="noopener">analysis</a> used satellite imagery to map the locations of oil and gas development in the Lake Eyre Basin since the first oil wells were established in late 1950s.</p> <p>We found 831 oil and gas production and exploration wells exist on the floodplains of the Lake Eyre Basin – almost 99% of them on the Cooper Creek floodplains. The wells go under the river and its floodplains into the geological Cooper Basin, considered to have the most important onshore petroleum and natural gas deposits in Australia.</p> <p>Our research also shows how quickly oil and gas mining in the Lake Eyre Basin is set to grow. We identified licensing approvals or applications covering 4.5 million hectares of floodplains in the Lake Eyre Basin, across South Australia and Queensland.</p> <p>The <a href="https://www.bioregionalassessments.gov.au/assessments/geological-and-bioregional-assessment-program/cooper-basin/cooper-gba-region-stage-two-report" target="_blank" rel="noopener">CSIRO</a> recently examined likely scenarios of 1,000 to 1,500 additional unconventional gas wells in the Cooper Basin in the next 50 years. It predicted these wells would built be on “pads” – areas occupied by mining equipment or facilities – about 4 kilometres apart. They would typically access gas using horizontal drilling and hydraulic fracturing, or fracking.</p> <p>Fracking is the process of extracting so-called “unconventional gas”. It involves using water and chemicals to fracture deep rocks to extract the gas. This polluted water, known to be <a href="https://www.nature.com/articles/srep46582" target="_blank" rel="noopener">toxic to fish</a>, is brought back to the surface and stored in dams.</p> <p>Two locations we focused on were in South Australia at the protected, <a href="https://www.environment.sa.gov.au/topics/water/wetlands/coongie-lakes" target="_blank" rel="noopener">Ramsar-listed Coongie Lakes site</a>, which was recognised as internationally significant in 1987. The other site was in Queensland’s channel country, also on the Cooper floodplain.</p> <p>In total across the Coongie Lakes sites, we found a three-fold increase in wells: from 95 in 1987 to 296 last year. We also identified 869 kilometres of roads and 316 hectares of storage pits, such as those that hold water.</p> <p>Some of these dams could potentially hold polluted fracking water and become submerged by flooding, particularly at Coongie Lakes.</p> <h2>A disaster waiting to happen?</h2> <p>Examples from around the world already show oil and gas exploration and development can reduce water quality by interrupting sediments and leading to elevated <a href="https://www.mdpi.com/2073-4441/12/4/941" target="_blank" rel="noopener">chemical</a> <a href="https://www.pnas.org/doi/10.1073/pnas.1213871110" target="_blank" rel="noopener">concentrations</a>. Production waste can also degrade floodplain <a href="https://iopscience.iop.org/article/10.1088/1742-6596/1515/3/032037" target="_blank" rel="noopener">vegetation</a>.</p> <p>The <a href="https://www.bioregionalassessments.gov.au/assessments/geological-and-bioregional-assessment-program/cooper-basin/cooper-gba-region-stage-two-report" target="_blank" rel="noopener">CSIRO says</a> risks associated with oil and gas development in the Cooper Basin include:</p> <ul> <li>dust and emissions from machinery that may cause habitat loss, including changes to air quality, noise and light pollution</li> <li>disposal and storage of site materials that may contaminate soil, surface water and/or groundwater through accidental spills, leaks and leaching</li> <li>unplanned fracking and drilling into underground faults, unintended geological layers or abandoned wells</li> <li>gas and fluids contaminating soil, surface water, groundwater and air</li> <li>changes to groundwater pressures could potentially reactivate underground faults and induce earthquakes.</li> </ul> <p>Fracking for unconventional gas also requires drawing <a href="https://www.bioregionalassessments.gov.au/assessments/geological-and-bioregional-assessment-program/cooper-basin/cooper-gba-region-stage-two-report" target="_blank" rel="noopener">large amounts of water</a> from rivers and groundwater.</p> <h2>The laws have failed</h2> <p>Our findings raise significant questions for Australian governments and the community.</p> <p>Are we prepared to accept industrialisation of the Lake Eyre Basin, and the associated risk of pollution and other environmental damage? Have the companies involved earned a social licence for these activities? Where do the profits end up, and who will bear the social, environmental and financial costs of such intense development?</p> <p>Clearly, state and federal environmental protections have failed to stop unfettered development of the basin.</p> <p>These policies include the Lake Eyre Basin <a href="https://www.dcceew.gov.au/water/policy/national/lake-eyre-basin/agreement" target="_blank" rel="noopener">Agreement</a>, signed by the states, the Commonwealth and the Northern Territory, which has been in place since 2000.</p> <p>Australia’s federal environment law – the Environment Protection and Biodiversity Conservation Act – is supposed to protect nationally important areas such as Ramsar wetlands. Yet our research identified that just eight developments in the basin were referred to the Commonwealth government for approval and with only one deemed significant enough for assessment. This legislation does not deal adequately with the cumulative impacts of development.</p> <p>And finally, gas extraction and production is <a href="https://theconversation.com/1-in-5-fossil-fuel-projects-overshoot-their-original-estimations-for-emissions-why-are-there-such-significant-errors-177714" target="_blank" rel="noopener">associated with</a> substantial “fugitive” emissions - greenhouse gases which escape into the atmosphere. This undermines Australia’s emissions reduction efforts under the Paris Agreement.</p> <p>The governments of South Australia and Queensland should restrict mining development in the Lake Eyre Basin. And stronger federal oversight of this nationally significant natural treasure is urgently needed.</p> <p>In response to this article, Chief executive of the Australian Petroleum Production &amp; Exploration Association, Samantha McCulloch, said in a statement:</p> <blockquote> <p>The oil and gas industry takes its responsibilities to the environment and to local communities seriously and it is one of the most heavily regulated sectors in Australia. The industry has been operating in Queensland for more than a decade and the gas produced in Queensland plays an important role in Australia’s energy security.</p> </blockquote> <p><strong>This article originally appeared on <a href="https://theconversation.com/the-magnificent-lake-eyre-basin-is-threatened-by-831-oil-and-gas-wells-and-more-are-planned-is-that-what-australians-really-want-191078" target="_blank" rel="noopener">The Conversation</a>.</strong></p> <p><em>Image: Shutterstock</em></p>

Warming oceans may force New Zealand’s sperm and blue whales to shift to cooler southern waters

<p>The world’s oceans are absorbing more than <a href="https://www.un.org/en/climatechange/science/climate-issues/ocean-impacts" target="_blank" rel="noopener">90% of the excess heat and energy</a> generated by rising greenhouse gas emissions.</p> <p>But, as the oceans keep warming, rising sea temperatures generate unprecedented cascading effects that include the melting of polar ice, rising seas, marine heatwaves and ocean acidification.</p> <p>This in turn has profound impacts on marine biodiversity and the lives and livelihoods of coastal communities, especially in island nations such as New Zealand.</p> <p>In our latest <a href="https://www.sciencedirect.com/science/article/pii/S1470160X22007075?via%3Dihub" target="_blank" rel="noopener">research</a>, we focused on great whales – sperm and blue whales in particular. They are crucial for maintaining healthy marine ecosystems, but have limited options to respond to climate change: either adapt, die, or move to stay within optimal habitats.</p> <p>We used mathematical models to predict how they are likely to respond to warming seas by the end of the century. Our results show a clear southward shift for both species, mostly driven by rising temperatures at the sea surface.</p> <h2>Computing the fate of whales</h2> <p>Data on the local abundance of both whales species are <a href="https://www.int-res.com/abstracts/meps/v690/p201-217/" target="_blank" rel="noopener">deficient</a>, but modelling provides a powerful tool to predict how their range is likely to shift.</p> <p>We used a <a href="http://macroecointern.dk/pdf-reprints/AraujoNew2007.pdf" target="_blank" rel="noopener">combination of mathematical models</a> (known as correlative species distribution models) to predict the future range shifts of these whale species as a response to three future climate change scenarios of differing severity, as outlined by the Intergovernmental Panel on Climate Change (<a href="https://www.ipcc.ch/" target="_blank" rel="noopener">IPCC</a>).</p> <p>We applied these models, using the whales’ present distributions, to build a set of environmental “rules” that dictate where each species can live. Using climate-dependent data such as sea-surface temperature and chlorophyll A (a measure of phytoplankton growth), as well as static data such as water depth and distance to shore, we applied these rules to forecast future habitat suitability.</p> <p>We chose a scenario of “<a href="https://www.nature.com/articles/d41586-020-00177-3" target="_blank" rel="noopener">modest</a>” response to cutting greenhouse gas emissions (the IPCC’s mitigation strategy RCP4.5), which is the most likely given the current policies, and a worst-case scenario (no policy to cut emissions, RCP8.5), assuming the reality will likely be somewhere between the two.</p> <p>Our projections suggest current habitats in the ocean around the North Island may become unsuitable if sea-surface temperatures continue to rise.</p> <p>These range shifts become even stronger with increasing severity of climate change. For sperm whales, which are currently abundant off Kaikōura where they support eco-tourism businesses, the predicted distribution changes are even more evident than for blue whales, depending on the climate change scenario.</p> <p>While our results do not predict an overall reduction in suitable habitat that would lead to local extinctions, the latitudinal range shifts are nevertheless bound to have important ecological consequences for New Zealand’s marine ecosystems and the people who depend on them.</p> <h2>How whales maintain ecosystems</h2> <p>Great whales are marine ecosystem engineers. They modify their habitats (or create new ones), to suit their needs. In fact, these activities create conditions that other species rely on to survive.</p> <p>They engineer their environment on several fronts. By feeding in one place and releasing their faeces in another, whales convey minerals and other nutrients such as nitrogen and iron from the deep water to the surface, as well as across regions. This process, known as a “<a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0013255" target="_blank" rel="noopener">whale pump</a>”, makes these nutrients available for phytoplankton and other organisms to grow.</p> <p>This is very important because phytoplankton contributes about <a href="https://education.nationalgeographic.org/resource/plankton-revealed" target="_blank" rel="noopener">half of all oxygen to the atmosphere</a> and also captures <a href="https://www.imf.org/Publications/fandd/issues/2019/12/natures-solution-to-climate-change-chami" target="_blank" rel="noopener">about 40% of all released carbon dioxide</a>. By helping the growth of phytoplankton, whales indirectly contribute to the <a href="https://theconversation.com/tiny-plankton-drive-processes-in-the-ocean-that-capture-twice-as-much-carbon-as-scientists-thought-136599" target="_blank" rel="noopener">natural ocean carbon sink</a>.</p> <p>On top of this, each great whale accumulates about <a href="https://www.arcticwwf.org/the-circle/stories/protecting-the-earth-by-protecting-whales/" target="_blank" rel="noopener">33 tonnes of carbon dioxide in their body</a>, which they take to the ocean floor when they die and their carcass sinks.</p> <p> </p> <p>Ultimately, the impact of warming oceans on whale distribution is an additional stress factor on ecosystems already under pressure from wider threats, including acidification, pollution and over-exploitation.</p> <h2>A way forward to help whales</h2> <p>Sperm whales are the largest toothed whales (odontocetes) and deep-diving apex predators. They primarily feed on squid and fish that live near the bottom of the sea.</p> <p>Blue whales are baleen whales (mysticetes) and filter small organisms from the water. They feed at the surface on zooplankton, particularly dense krill schools along coastlines where cold water from the deep ocean rises toward the surface (so-called <a href="https://oceanservice.noaa.gov/facts/upwelling.html" target="_blank" rel="noopener">upwelling areas</a>).</p> <p>These differences in feeding habits lead to divergent responses to ocean warming. Blue whales show a more distinct southerly shift than sperm whales, particularly in the worst-case scenario, likely because they feed at the surface where ocean warming will be more exacerbated than in the deep sea.</p> <p>Both species have important foraging grounds off New Zealand which may be compromised in the future. Sperm whales are currently occurring regularly off Kaikōura, while blue whales forage in the South Taranaki Bight.</p> <p>Despite these ecological differences, our results show that some future suitable areas around the South Island and offshore islands are common to both species. These regions could be considered sanctuaries for both species to retreat to or expand their habitat in a warming world. This should warrant <a href="https://environment.govt.nz/assets/Publications/Files/Environmental-Report-Card-Marine-Areas-with-Legal-protection_0.pdf" target="_blank" rel="noopener">increased protection of these areas</a>.</p> <p><strong>This article originally appeared on <a href="https://theconversation.com/warming-oceans-may-force-new-zealands-sperm-and-blue-whales-to-shift-to-cooler-southern-waters-188522" target="_blank" rel="noopener">The Conversation</a>.</strong></p> <p><em>Image: Shutterstock</em></p>

“Split second” moment leaves little boy severely burned

<p><span style="font-weight: 400;"> Looking away for a “split second” was all it took for a little boy to suffer horrific injuries from a common household item.</span></p> <p><span style="font-weight: 400;">In July last year, aged care nurse Georgette Lysaght went to work and left her husband to look after their two children, six-month-old Ben and older sister Brooklyn, in the family room of their Moree home in northwest NSW.</span></p> <p><span style="font-weight: 400;">Mr Lysaght was sitting on the floor while the children played, with Ben using a walker to make his way around the room, when Mr Lysaght turned to reach behind him for his ringing phone.</span></p> <p><span style="font-weight: 400;">The room had a gas heater built into a faux fireplace that served as the home’s only heat source.</span></p> <p><span style="font-weight: 400;">“He had turned to pick up the phone and answer it because it had rung and in that split second Ben had pushed himself to the gas heater and grabbed hold of the bars,” Ms Lysaght said.</span></p> <p><span style="font-weight: 400;">“Initially his hands got stuck to them and he didn’t make a sound … [Ben was] red in the face from that pain where you can’t even talk.”</span></p> <p><span style="font-weight: 400;">What Mr Lysaght did next saved his son from having to receive a skin graft, doctors would later say.</span></p> <p><span style="font-weight: 400;">The quick-thinking dad picked up Ben and ran his burned hand under a tap.</span></p> <p><span style="font-weight: 400;">When Mr Lysaght then called his wife, she could hear Ben now screaming in the background.</span></p> <p><span style="font-weight: 400;">“All [my husband] said was ‘burn’ … my husband couldn’t even talk, he was just in so much shock,” she said.</span></p> <p><span style="font-weight: 400;">When Ms Lysaght got home the parents rushed Ben to Moree Hospital, after wrapping his hand in a damp cloth and using ice to keep cool water running over the burn.</span></p> <p><span style="font-weight: 400;">“Ben actually wasn’t crying when [hospital staff] were touching it. I didn’t know at the time and I was like ‘that’s good right? It doesn’t hurt as much’,” Ms Lysaght said.</span></p> <p><span style="font-weight: 400;">“They said no, it’s bad because it means it’s gone down so deep he can’t feel it on the top layers ... he had basically fried all his nerves.”</span></p> <p><span style="font-weight: 400;">As a result of his third degree burns, the tips of two of Ben’s fingers were removed as that part of the hand had ‘died’.</span></p> <p><span style="font-weight: 400;">After the surgery, Mr and Ms Lysaght had to take Ben to The Children’s Hospital in Westmead, Sydney, for fortnightly and monthly physio and fitting of new casts to protect the burn.</span></p> <p><span style="font-weight: 400;"><img style="width: 500px; height: 500px;" src="https://oversixtydev.blob.core.windows.net/media/7841549/80aa7e1439b7f4b51eb4e56e44d4b953.jpg" alt="" data-udi="umb://media/a4dad41b3d3147558e2be39d86207622" /></span></p> <p><span style="font-weight: 400;">Nearly a year later, Ben’s hand has now mostly healed, but he is yet to regain feeling in his hand. Doctors have said the sensation will eventually come back.</span></p> <p><span style="font-weight: 400;">“If he picks things up with that hand and he puts it in his mouth, he gets a shock, he’s not expecting it to be cold or hot,” Ms Lysaght said.</span></p> <p><span style="font-weight: 400;">While too young to fully remember the incident, Ben does get upset whenever he sees a gas heater and the Lysaghts have since moved to a new home with split-cycle air conditioning and heating instead.</span></p> <p><span style="font-weight: 400;">By sharing their story, Ms Lysaght hopes to help other families become more aware of the dangers heaters pose and how knowing first aid is so vital.</span></p> <p><strong>What to do after a burn</strong></p> <p><span style="font-weight: 400;">After a burn, run the affected area under cool running water for 20 minutes - and avoid using butter, gel, cream, iced water or ice.</span></p> <p><span style="font-weight: 400;">“When a burn occurs, the first step in treatment should always be cool running water. This can reduce the thickness of the burn, as well as the time a burn will take to heal,” said Dr Torey Lawrence, head of the burns unit at The Children’s Hospital in Westmead and Sydney Children’s Hospital Randwick.</span></p> <p><span style="font-weight: 400;">He said using cold water was the “only effective first aid for burns”.</span></p>

<p><span style="font-weight: 400;">The Climate Council has released new research finding the use of gas is Australian households puts kids at a higher risk of asthma.</span></p> <p><span style="font-weight: 400;">Additionally, the </span><a href="https://www.climatecouncil.org.au/resources/gas-habit-how-gas-harming-health/"><span style="font-weight: 400;">Kicking the Gas Habit: How Gas is Harming Our Health</span></a><span style="font-weight: 400;"> report also found that gas-powered cooking has more harmful impacts on Australia.</span></p> <p><span style="font-weight: 400;">Using gas for cooking and heating harms our health, while the extraction process exposes communities to hazardous substances.</span></p> <p><span style="font-weight: 400;">“Far from the ‘clean and natural’ image that the gas industry markets, gas cooktops are known to produce contaminants that increase the risk of childhood asthma, in particular, nitrogen dioxide and certain forms of particulate matter, like PM2.5,” the report said.</span></p> <p><span style="font-weight: 400;">The Climate Council also found that children and those in poorer households are at the highest risk from gas use in home and schools.</span></p> <p><strong>How does gas at home affect kids?</strong></p> <p><span style="font-weight: 400;">Kate Charlesworth, Climate Council spokeswoman and report author, compared the risk of a child developing asthma from living in a home using gas to a child living with household cigarette smoke.</span></p> <p><span style="font-weight: 400;">“Cooking with gas is estimated to be responsible for up to 12 per cent of the childhood asthma burden in Australia,” she said.</span></p> <p><span style="font-weight: 400;">Asthma Australia CEO Michele Goodman called on families to do everything they can “to improve health outcomes for our children”.</span></p> <p><span style="font-weight: 400;">“Australia has some of the highest rates of asthma in the world, and it is the leading cause of disease burden among school-aged children,” she said.</span></p> <p><span style="font-weight: 400;">“Some people will be shocked to learn that cooking dinner on a gas stove could be contributing to their child’s asthma symptoms, we need education to improve awareness for indoor air pollution,” she continued.</span></p> <p><span style="font-weight: 400;">To reduce the risk, Goodman says people should increase the ventilation at home by using “modern extraction fans over gas stoves, flues for gas heaters, and simple measures like opening windows.”</span></p> <p><span style="font-weight: 400;">But, she said “this won’t eliminate the risk completely.”</span></p> <p><strong>Gas extraction also harms communities</strong></p> <p><span style="font-weight: 400;">The report also found that people living near coal seam gas developments in Queensland’s Darling Downs “were more likely to be hospitalised for tumours, as well as blood and immune diseases.”</span></p> <p><span style="font-weight: 400;">It called on the government to shift away from gas and adopt cleaner energy alternatives like solar or wind power.</span></p> <p><span style="font-weight: 400;">“Gas is a polluting fossil fuel. Governments can prevent health issues, and reduce harm, by helping households and the country move away from gas,” the report said.</span></p> <p><span style="font-weight: 400;">Gas extraction and processing was also found to “involve many hazardous substances, including those that cause cancer, interfere with childhood development, trigger asthma and contaminate the local environment through airborne pollution and wastewater.”</span></p> <p><strong>What is the Climate Council?</strong></p> <p><span style="font-weight: 400;">According to </span><a href="https://www.climatecouncil.org.au/"><span style="font-weight: 400;">its website</span></a><span style="font-weight: 400;">, the Climate Council is the country’s leading climate change communications organisation that has been providing advice to the public on climate change and science-based solutions since its inception in 2013.</span></p> <p><span style="font-weight: 400;">“We’re made up of some of the country’s leading climate scientists, health, renewable energy and policy experts, as well as a team of staff, and a huge community of volunteers and supporters who power our work.</span></p> <p><span style="font-weight: 400;">“As an independent voice on climate change, we get climate stories into the media, produce hard-hitting reports, call out misinformation as we see it and promote climate solutions such as the transition to renewables.”</span></p>

A chemical engineer explains: What makes pepper spray so intense? And is it a tear gas?

<p>In recent weeks, the world has looked on as governments use chemical irritants to control protesters and riots. Whether it’s tear gas, pepper spray, mace or pepper balls, all have one thing in common: they’re chemical weapons.</p> <p>Chemical warfare agents have been used twice in Sydney in the past week alone. Police <a href="https://www.abc.net.au/news/2020-06-07/sydney-police-defend-pepper-spray-use-on-protesters/12330558">pepper-sprayed</a> demonstrators at Central Station, following Saturday’s major Black Lives Matter protest.</p> <p>The next day, tear gas <a href="https://www.abc.net.au/news/2020-06-08/tear-gas-fired-into-exercise-yard-of-sydney-long-bay-jail/12332572">was used</a> to break up a fight at Long Bay jail, as prison guards filled an exercise yard with tear gas canisters – also impacting nearby residents.</p> <p>These events followed the deployment of <a href="https://edition.cnn.com/2020/06/05/politics/park-police-tear-gas/index.html">chemical riot control agents</a> – specifically “pepper bombs” – in Washington DC last week. They were used to clear protesters from a public park so President Donald Trump could walk from the White House to a nearby church for a photo opportunity.</p> <p>The White House made a highlight reel to celebrate Trump’s heroic walk across the street for his bible photo op...</p> <p>US Attorney General William Barr said “<a href="https://www.factcheck.org/2020/06/the-continuing-tear-gas-debate/">there was no tear gas used</a>”, claiming “pepper spray is not a chemical irritant. It’s not chemical.”</p> <p>I’m a chemical engineer and chemist who studies chemicals in the environment. So I thought I’d clear the air about what makes pepper spray such a powerful chemical irritant, and a chemical weapon.</p> <p><strong>What’s inside pepper spray?</strong></p> <p>The active compounds in pepper spray are collectively known as capsaicinoids. They are given the military symbol OC, for “oleoresin capsicum”.</p> <p>The most important chemical in OC is capsaicin. This is derived from chilli peppers in a chemical process that dissolves and concentrates it into a liquid. Capsaicin is the same compound that makes chillies hot, but in an intense, weaponised form.</p> <p>Not all capsaicinoids are obtained naturally. One called nonivamide (also known as PAVA or pelargonic acid vanillylamide) is mostly made by humans. PAVA is an <a href="https://cot.food.gov.uk/committee/committee-on-toxicity/cotstatements/cotstatementsyrs/cotstatements2002/pavastatement">intense irritant</a> used in <a href="https://www.theguardian.com/society/2018/dec/09/pepper-spray-used-in-non-violent-situations-in-prison-pilot">artificial pepper spray</a>.</p> <p><strong>Is pepper spray a tear gas?</strong></p> <p>We’ve established pepper spray is a chemical, but is it also a kind of tear gas?</p> <p>“<a href="https://emergency.cdc.gov/agent/riotcontrol/factsheet.asp">Tear gas</a>” is an informal term and a bit of a misnomer, because it isn’t a gas. Rather, tear gas refers to any weaponised irritant used to immobilise people.</p> <p>More specifically, tear gas is often used to describe weapons that disperse their irritants in the air either as liquid aerosol droplets (such as <a href="https://www.popularmechanics.com/science/health/a28904691/how-tear-gas-works/">gas canisters</a>), or as a powder (such as pepper balls). This definition distinguishes tear gas from personal self-defence sprays which use foams, gels and liquids.</p> <p>Tear gas canisters typically contain the irritants 2-chlorobenzalmalononitrile (CS) and phenacyl chloride (CN). Both CS and CN are man-made chemicals discovered in a lab, unlike capsaicin (the traditional ingredient in pepper spray).</p> <p>But despite capsaicin coming from chilli peppers, pepper spray is still a weaponised irritant that can be delivered as an aerosol or powder. It should unequivocally be considered a type of tear gas.</p> <p><strong>Pepper spray as a weapon</strong></p> <p>The chemical irritants OC, CS and CN have military symbols because they are chemical weapons. They are termed “<a href="https://www.wbur.org/news/2020/06/10/rubber-bullets-protesters-victoria-snelgrove-boston">less-lethal</a>” because they are less likely to kill than conventional weapons. Their use, however, can still <a href="https://www.forbes.com/sites/judystone/2020/06/08/tear-gas-and-pepper-spray-can-maim-kill-and-spread-coronavirus/#47f17a2a725f">cause fatalities</a>.</p> <p>Technically, pepper spray and other tear gases are classified as lachrymatory agents. <a href="https://theconversation.com/what-is-tear-gas-139958">Lachrymatory agents</a> attack mucous membranes in the eyes and respiratory system.</p> <p>Pepper spray works almost instantly, forcing the eyes to close and flood with tears. Coupled with coughing fits and difficulty breathing, this means the targeted person is effectively <a href="https://healthland.time.com/2011/11/22/how-painful-is-pepper-spray/">blinded and incapacitated</a>. Because lachrymatory agents work on <a href="https://www.ncbi.nlm.nih.gov/books/NBK544263/">nerve receptors</a> that help us sense heat, they also induce an intense burning sensation.</p> <p>The combined effects of pepper spray can last anywhere from 15 minutes to more than an hour.</p> <p>Lachrymatory agents emerged on the <a href="https://www.history.com/this-day-in-history/germans-introduce-poison-gas">battlefields of World War I</a>. Artillery shells were filled with chemicals such as <a href="https://www.compoundchem.com/2014/05/17/chemical-warfare-ww1/">xylyl bromide and chloroacetone</a> and fired at enemy soldiers. Agents that induce choking, blistering and vomiting were added as the <a href="https://www.nytimes.com/2018/11/10/science/chemical-weapons-world-war-1-armistice.html">chemical arms race</a> escalated.</p> <p>In the 1920s, the <a href="https://www.un.org/disarmament/wmd/bio/1925-geneva-protocol/">Geneva Protocol</a> was enacted to ban the use of indiscriminate and often ineffective chemical weapons on the battlefield. Today, the unjustified use of chemical riot control agents <a href="https://www.aljazeera.com/indepth/opinion/2012/04/201242913130963418.html">threatens to erode</a> the systems that are meant to protect us from the most dangerous weaponised chemicals.</p> <p><em>Written by Gabriel da Silva.

How countries can recycle more buildings

<p>More than <a href="https://doi.org/10.1016/j.jclepro.2019.118710">35 billion tonnes</a> of non-metallic minerals are extracted from the Earth every year. These materials mainly end up being used to build homes, schools, offices and hospitals. It’s a staggering amount of resources, and it’s only too likely to increase in the coming years as the global population continues to grow.</p> <p>Thankfully, the challenges of sustainable construction, industrial growth and the importance of resource efficiency are now clearly recognised by governments around the world and are now at the forefront of strategy and policy.</p> <p>A critical component of the <a href="https://www.gov.uk/government/publications/securing-the-future-delivering-uk-sustainable-development-strategy">UK government’s sustainability strategy</a> concerns the way in which construction and demolition waste – CDW, as we call it in the trade – is managed. CDW comes from the construction of buildings, civil infrastructure and their demolition and is one of the heaviest waste streams generated in the world – 35% of the world’s landfill is made up of CDW.</p> <p>The EU’s <a href="https://ec.europa.eu/growth/content/eu-construction-and-demolition-waste-protocol-0_en">Waste Framework Directive</a>, which aims to recycle 70% of non-hazardous CDW by 2020, has encouraged the construction industry to process and reuse materials more sustainably. This directive, which favours preventive measures – for example, reducing their use in the first place – as the best approach to tackling waste, has been implemented in the UK since 2011. More specific to the construction industry, the <a href="https://www.sustainabilityexchange.ac.uk/berr-strategy-for-sustainable-construction">Sustainable Construction Strategy</a> also sets overall targets for diverting CDW from landfill.</p> <p>Policies worldwide recognise that the construction sector needs to take immediate action to reduce greenhouse gas (GHG) emissions, tackle the climate crisis and limit resource depletion, with a focus on adopting a <a href="https://theconversation.com/explainer-what-is-a-circular-economy-29666">circular economy</a> approach in construction to ensure the sustainable use of construction materials.</p> <p>Instead of simply knocking buildings down and sending the CDW to landfill, circular construction would turn building components that are at the end of their service life into resources for others, minimising waste.</p> <p>It would change economic logic because it replaces production with sufficiency: reuse what you can, recycle what cannot be reused, repair what is broken, and re-manufacture what cannot be repaired. It will also help protect businesses against a shortage of resources and unstable prices, creating innovative business opportunities and efficient methods of producing and consuming.</p> <p><strong>Changing the mind-set</strong></p> <p>The mind-set of the industry needs to change towards the cleaner production of raw materials and better circular construction models. Technical issues – such as price, legal barriers and regulations – that stand in the way of the solutions being rolled out more widely must also be overcome through innovation.</p> <p>Materials scientists, for example, are currently investigating and developing products that use processed CDW for manufacturing building components – for example, by crushing up CDW and using it to make new building materials.</p> <p>Technical problems around the reuse of recycled materials should be solved through clever material formulations and detailed property investigations. For instance, the high water absorption rate in recycled aggregates causes durability problems in wall components. This is something that research must address.<span class="attribution"><a href="https://www.shutterstock.com/image-photo/manager-engineer-check-control-automation-robot-1104780941" class="source"></a></span></p> <p>Moreover, it is illegal in the EU to use products that haven’t been certified for construction. This is one of the main obstacles standing in the way of the more widespread reuse of materials, particularly in a structural capacity. Testing the performance of materials for certification can be expensive, which adds to the cost of the material and may cancel out any savings made from reusing them.</p> <p>For the construction, demolition and waste management industries to remain competitive in a global marketplace, they must continue to develop and implement supply chain innovations that improve efficiency and reduce energy, waste and resource use. To achieve this, substantial research into smart, mobile and integrated systems is necessary.</p> <p>Radically advanced robotic artificial intelligence (AI) systems for sorting and processing CDW must also be developed. Many industries are facing an uncertain future and today’s technological limitations cannot be assumed to apply. The construction industry is likely to be significantly affected by the potential of transformative technologies such as AI, 3D printing, virtual/augmented reality and robotics. The application of such technologies presents both significant opportunities and challenges.</p> <p><strong>A model for the future</strong></p> <p>As the image below shows, we have developed a concept for an integrated, eco-friendly circular construction solution.</p> <p><img src="https://images.theconversation.com/files/304567/original/file-20191201-156095-1h42cnl.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt="" /> <span class="caption"></span> <span class="attribution"><span class="license">Author provided</span></span></p> <p>Advanced sensors and AI that can detect quickly and determine accurately what can be used among CDW and efficient robotic sorting could aid circular construction by vastly <a href="https://doi.org/10.1016/j.autcon.2018.05.005">improving the recycling of a wide range of materials</a>. The focus should be on the smart dismantling of buildings and ways of optimising cost-effective processes.</p> <p>The industry must also be inspired to highlight and prove the extraordinary potential of this new construction economy. We can drive this through a combination of creative design, focused academic research and applied technology, external industry engagement and flexible, responsive regulation.</p> <p>Only through a combination of efforts can we start to recycle more buildings, but I’m confident that with the right will – and the right investment – we can start to massively reduce the amount of materials we pull from the ground each year and move towards a truly sustainable future.<!-- Below is The Conversation's page counter tag.

These easy tips will save you hundreds on petrol

<p>Fuel costs can put a major dent in the family budget, but fortunately there are plenty of things you can do to reduce your consumption.</p> <p>The recent spell of low fuel prices has been welcome relief for many of us who depend on the car for transport, but sooner or later they will start heading north again. It makes a lot of sense, therefore, to do whatever you can to improve fuel efficiency. This can not only save you money, it will also reduce your carbon footprint. Here are a few pointers on what you can do to reduce your consumption.</p> <p><strong>Can LPG or diesel save you money?<br /></strong>This is often a hotly contested debate and the many variables involved can make it difficult to compare, but there is a strong argument that both diesel and LPG can be more budget friendly.</p> <p>LPG certainly uses more fuel to drive the same distance as petrol due to the lower energy content of LPG, but the cost of LPG compared to petrol more than offsets this disadvantage. The downside of LPG is that a car fitted with LPG is more expensive to buy and the cost of converting a car from petrol to LPG is no longer subsidised by the government. This means that the cost benefit of the fuel will take some time to make up for the upfront cost of purchase, but if you are doing a reasonable distance every year then it could well be worth the switch.</p> <p>Diesel too can offer potential savings. It has gone a long way to shedding its image as a smelly and noisy way to get around, thanks to improvements in engine technology over recent years. Diesel engines are getting quieter and cleaner and are now available even in many smaller cars, so it is not surprising that they are taking an increasing share of the new car market.</p> <p>Fuel efficiency is one of the key reasons for this, with diesel having a significant advantage in economy if all other factors are equal. In days gone by the cost per litre of diesel was prohibitive compared to petrol, but this balance has now well and truly swung the other way.</p> <p>The cost of a diesel car will still be greater than its petrol equivalent, but as with LPG, the more driving you do the quicker you will claw back the extra upfront cost.</p> <p><strong>How reliable are the fuel efficiency labels?<br /></strong>If you have been shopping for a new car you will be aware of the mandatory labels that now appear on the windscreen. These supposedly provide an indication of the fuel consumption for both urban and “extra urban” (country) driving.</p> <p>The manufacturers are responsible for testing their own cars and this is done according to conditions set by Australian Design Rules. What many people don’t realise, however, is that they are not done on the road, but rather are done on a dynamometer with artificially created air flow to simulate actual driving conditions.</p> <p>The controlled guidelines for the test mean that they are indeed a good way to compare different vehicles relative to each other, but their usefulness stops there. Because the test conditions are so artificial, they bear little resemblance to actual realistic driving conditions and consequently the results are generally a lot more favourable than what you will experience in reality.</p> <p>In short – you can use them to compare efficiency between different cars, but don’t use them to plan your weekly fuel budget!</p> <p><strong>9 ways to drive for better fuel efficiency<br /></strong>When it comes to the actual driving of your car from week to week, there are many ways to make a big difference to your fuel consumption. Here are our top tips:</p> <p>1. Lazy gear selection in a manual car can chew through the juice. Avoid sitting in a low gear once revs are sufficient to change up and also avoid sitting in a high gear when the engine is straining to maintain revs. </p> <p>2. When driving an automatic stay alert when using the accelerator and ease off slightly when you can hear the engine getting ready to change up.</p> <p>3. Erratic braking and acceleration guzzles fuel, so drive smoothly with gradual acceleration and avoid rushing to the speed limit if you can see that the traffic ahead will likely require you to brake.

Why the increase of gas prices isn’t slowing down anytime soon

<p>“The Liberal-National government will help secure gas supplies, put downward pressure on prices and encourage new investment in gas supplies,” <a href="https://minister.environment.gov.au/taylor/news/2019/government-acts-deliver-affordable-reliable-gas">Tuesday’s announcement</a> says.</p> <p>Only a supreme optimist would expect it to do all three.</p> <p>Ministers Frydenberg, Canavan and Taylor have announced a <a href="https://minister.environment.gov.au/taylor/news/2019/government-acts-deliver-affordable-reliable-gas">suite of measures</a>, none of which are new, hard policy. Some are a continuation of existing measures, some are political weapons directed at state governments, and some are tantalysingly speculative ideas.</p> <p>The background to the announcements is that Asian spot prices for liquefied natural gas have fallen significantly, with increasing international supply and unusually weak demand in the northern hemisphere.</p> <p>Not surprisingly, overseas customers for Australia’s liquefied natural gas locked into long-term contracts and cost-squeezed Australian users are frustrated that they are not paying lower prices. Naturally, they were quieter when spot prices were climbing.</p> <p><strong>Behind the scenes, things are improving</strong></p> <p>At the same time, there has been some good news on supply.</p> <p>Origin and Santos are proceeding with a substantial exploration program in the Northern Territory after that government lifted its moratorium on the use of fracking for gas development. The Territory’s Beetaloo Basin has been identified as a major new onshore gas source.</p> <p>And good news on supply to industrial users. Producers such as APLNG and Santos have been signing new contracts with large users who have in the past have been finding it hard to get reliable supply at acceptable prices, among them Orica, Incitec Pivot and Brickworks.</p> <p>And good news on transparency. The Australian competition and Consumer Commission has started publishing so-called export netback and transportation prices. Netback is the price gas supplier can expect to receive for exporting its gas after taking account of the delivered price and subtracting the costs of liquefying natural gas and shipping it.</p> <p><strong>The new measures can’t hurt…</strong></p> <p>A trigger for this week’s announcements was the government’s deal with Senator Rex Patrick over tax cut legislation. Among the measures promised are three worthy of comment.</p> <p>First, the government will “consider” options for a prospective national gas reservation scheme. This could mean that gas producers wishing to develop new fields on the east coast and the Northern Territory would have to set aside some of what they produce for domestic use, as happens in Western Australia.</p> <p>It is clearly controversial. It could distort incentives for exploration and act as a subsidy for gas users to the detriment of producers and taxpayers. Whether the worst can be avoided and some good delivered will depend on what emerges.</p> <p>And there mightn’t be much that does emerge. It’s not even clear that the Commonwealth has the Constitutional power to unilaterally impose a domestic reservation scheme.</p> <p>The industry will be relieved that it hasn’t proposed price control, or a retrospective reservation scheme, which would have been even worse.</p> <p>Second, the government is hoping its commitment will put pressure on state and territory governments to remove “unwarranted restrictions on gas developments”. A successful move to a consistent, science-based, national approach to gas development, including the use of fracking technologies, would be a big step forward.</p> <p>Third is a list of actions designed to improve transparency and liquidity in the gas market, both wholesale and transportation. It is a worthwhile objective. While “formalised collective bargaining” by industrial users sounds like an intriguing possibility, it is uncertain what will emerge.</p> <p><strong>…but they won’t amount to much</strong></p> <p>Gas supply and prices will not improve without additional supply sources. Prices are most unlikely to fall by two thirds to their historical levels of around a third of current prices.</p> <p>Wishful thinking will not change the hard facts of rising costs and depleting easier-to-extract resources. Equally wishful thinking that governments should just get out of the way of the market fails to understand the economic damage that is being done by a poorly operating, concentrated and largely opaque market. Government intervention was inevitable.</p> <p>If this suite of announced actions prompts even a modest increase in supply, and further improvements in market transparency and liquidity, and confidence that consumers are not being ripped off, it will be a success.</p> <p><em>Written by Tony Wood.

The great divide: How everyday Aussies are picking up Australia’s energy tab

<p>It’s official. Three different regulatory bodies have come out and said it – Australia’s energy market is anything but competitive. First it was the ACCC and IPART – now the AEMC has found that there are savings of up to $1,500 a year* for Aussies if they switch from the worst available service on offer to the best.</p> <p>Even the Prime Minister has proclaimed there are close to 2 million Aussies paying more than they need to for electricity because they’re stuck in contracts that are either too expensive or inappropriate.</p> <p>Every day at <span><a href="https://electricityandgas.com.au/over-sixty/?utm_medium=sponsoredarticle&amp;utm_source=oversixty&amp;utm_campaign=july">ElectricityandGas.com.au</a></span> we hear from Aussies who are fed up with forking out thousands of their hard-earned dollars for their energy bills. And every day we help them find a better deal. We know just how easy it is for people who don’t know the energy market to waste their money AND how easy it is to put a stop to it.</p> <p><strong>Here's how you do it</strong></p> <p>Step 1: Select your state below.</p> <p>Step 2: After answering a few questions, you will have the opportunity to compare quotes in your area and could be eligible for significant savings.</p> <p><span><a href="https://electricityandgas.com.au/form/stepn-tw/over-sixty/?utm_medium=sponsoredarticle&amp;utm_source=oversixty&amp;utm_campaign=july"><img style="width: 500px; height: 122.72727272727273px;" src="https://oversixtydev.blob.core.windows.net/media/7828622/july-cta-state-tiles-880.jpg" alt="" data-udi="umb://media/eb5f1c77ff5742578e4c608a06e571fa" /></a></span></p> <p>All of Australia’s energy market regulators recommend that Aussies review their bills every year. This is because energy providers have been able to change rates without informing their customers, and because cheap introductory offers are used to lure people in before they find themselves hit with a big rate hike.</p> <p>On top of all this, confusing pricing, sparse market competition and higher wholesale costs have caused electricity bills to surge by a staggering 60 per cent over the last 10 years. The result? It’s everyday Aussies, trusting that their provider won’t rip them off, who get stuck with the worst rates.</p> <p>“Market deregulation was supposed to reduce costs and make energy more affordable for everyday Aussies,” says <span><a href="https://electricityandgas.com.au/over-sixty/?utm_medium=sponsoredarticle&amp;utm_source=oversixty&amp;utm_campaign=july">ElectricityandGas.com.au</a></span> founder Jon Leane.</p> <p>“But the reality we have seen is incredible deals for some contrasted with complete rip-offs for others. It’s just not fair for the people stuck with the raw end of the deal.”</p> <p>Leane added, “That’s why we started <span><a href="https://electricityandgas.com.au/over-sixty/?utm_medium=sponsoredarticle&amp;utm_source=oversixty&amp;utm_campaign=july">ElectricityandGas.com.au</a></span> because, with prices on the rise, we think Aussies deserve the chance to find a better deal. Why should you be paying more for the exact same thing simply because you’re not a market expert?”</p> <p>You get access to no mark-up policies from energy providers across Australia, making it easy to find the best deals in your area. This service makes comparison shopping for energy easy, and best of all it’s totally cost and obligation free.</p> <p>Just last month almost 40,000 people chose <span><a href="https://electricityandgas.com.au/over-sixty/?utm_medium=sponsoredarticle&amp;utm_source=oversixty&amp;utm_campaign=july">ElectricityandGas.com.au</a></span> to help them compare, switch and save. Cheaper bills are only a few clicks away. Why not join them?</p> <p><strong>Here's how you do it</strong></p> <p>Step 1: Select your state below.</p> <p>Step 2: After answering a few questions, you will have the opportunity to compare quotes in your area and could be eligible for significant savings.</p> <p><span><a href="https://electricityandgas.com.au/form/stepn-tw/over-sixty/?utm_medium=sponsoredarticle&amp;utm_source=oversixty&amp;utm_campaign=july"><img style="width: 500px; height: 322.15909090909093px;" src="https://oversixtydev.blob.core.windows.net/media/7828621/july-cta-map-880.jpg" alt="" data-udi="umb://media/ade6f57fdecc414ea5a48c39a13e49d9" /></a></span></p> <p><em>*The Australian Competition &amp; Consumer Commission, the Independent Pricing and Regulatory Tribunal, and figures from the Australian Energy Market Commission for South Australians switching from the worst to the best offer.</em></p>
