Why Mr Bean is being blamed for decreasing electric vehicle sales

Rowan Atkinson has been blamed for a decrease in electric car sales, with a "damaging" article being debunked in the House of Lords. The actor and comedian, who is also a well-known car enthusiast, wrote an article for The Guardian, claiming he felt "duped" by electric vehicles, saying they aren't as eco-friendly as they are often portrayed. Atkinson says the problem with the vehicles' sustainable marketing focuses on just one part of the car’s operating life: what comes out of the exhaust pipes and ignores other elements such as the manufacturing and the mining of rare earth minerals, shipping and building of the batteries. These claims, and the article itself, have been addressed by the UK's House of Lords, with politicians blaming the story for a decrease in electric vehicle sales. UK think tank the Green Alliance says, “One of the most damaging articles was a comment piece written by Rowan Atkinson in The Guardian which has been roundly debunked.” Other deterrents identified by the committee were the high purchase price and insufficient charging infrastructure. Social media users were quick to take Atkinson's side in the debate, with one person writing on X, “If Rowan Atkinson is responsible, then give him a knighthood.” Another user says, “Rowan Atkinson with a degree and masters in Engineering. Knows more than those pushing electric cars.” "Apparently it's Mr Bean's fault for the poor take up of electric cars. Cancel him," another said. For the last 12 months, high power costs in the UK have meant that fast charging your electric car can be more expensive than refuelling a petrol or diesel vehicle. The UK is planning to ban sales of petrol and diesel vehicles from 2035, despite the slip in sales. Image credits: Getty Images

5 ultimate tips before you schedule heating and cooling maintenance in Adelaide

<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 Adelaide's climate, a reliable heating and cooling system isn't just a luxury – it's a must-have! Beyond comfort, maintaining these lifesavers at peak efficiency helps you tackle the temperature swings. But how do you ensure they're up to snuff year-round? <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;">Walk about our <a style="text-decoration: none;" href="https://www.metropolitanheatingandcooling.com.au/blog/how-often-should-i-schedule-heating-and-cooling-maintenance/"><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;">Maintenance and Routine Services Guide</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;">. They'll arm you with everything from understanding your unique system, spotting trouble early on, the cleaning nitty-gritty, right to zeroing in on the best time for that crucial maintenance in Adelaide. <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;">Now, let’s dive into these handy pointers and get you sorted, shall we? <h2 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 You Need to Remember</h2> <img src="https://oversixtydev.blob.core.windows.net/media/2023/12/HeatingCooling02.jpg" alt="" width="1280" height="720" /> <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;">Aside from air conditioner repairs and ducted gas heating repairs, diligently scheduling heating and cooling maintenance in Adelaide is just as important. Whether it's your first time scheduling one or you've done this before, these five tips can surely help you. <h3 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;">Tip #1: Understand Your Air Conditioning System</h3> <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 kind of air conditioning unit you have can make a big difference to your maintenance schedule. Could be split systems, ducted gas heating systems, or the lot. Most Adelaide homes use evaporative coolers, and servicing these units is quite a different ball game compared to reverse-cycle systems. <h3 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;">Tip #2: Recognise Signs of Trouble</h3> <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;">Today's air conditioning units are excellent at giving you a heads-up about an upcoming hassle. If it's not putting out enough cool air, or it's not running as it should, it might be time to call someone for those heating and cooling repairs. Nipping these problems in the bud is what you should be aiming for. <h3 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;">Tip #3: Regular Cleaning and Air Filter Changes</h3> <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;">Keeping your air conditioners' filters clean and changing them regularly is a clever way to keep your air conditioning service in tip-top shape. The air filters, in particular, play a big role in this. Blocked air filters can lead to poor airflow and overworking of the system, which bumps your running costs up the wall. <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;">However, don't stop at just swapping out the generic filters. Give the other components like the coils and fins in your air conditioner system a good clean as well. <h3 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;">Tip #4: Regular Cooling and Heating System Checks</h3> <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;">Keeping up with regular air conditioning repair services makes sure your system is always raring to go. Your system needs to be a ripper, ready to go the minute you need it. Maintenance involves cleaning and checking big brands like Mitsubishi Electric, making sure any faults are out of the picture. <h3 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;">Tip #5: Knuckling Down the Right Time for Check-up</h3> <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 best time to schedule air conditioning services or ducted gas, heating, and cooling systems repairs is before peak use - early autumn for heating systems and early spring for your cooling systems. This way, you're sorted with a climate-controlled environment just when you need it. <h2 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 Importance of Scheduling Heating and Cooling Maintenance</h2> <img src="https://oversixtydev.blob.core.windows.net/media/2023/12/HeatingCooling03.jpg" alt="" width="1280" height="720" /> <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;">We have our busy days, and there are times when scheduling maintenance for our heating and cooling unit is the last thing on our list. However, there are plenty of reasons why sticking to heating and cooling maintenance like glue is so important: <h3 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;">It Keeps Your Systems Efficient</h3> <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;">Routine maintenance keeps your system running efficiently. A well-maintained unit uses less energy to run and is therefore less likely to punch a hole in your wallet when the energy bill shows up. <h3 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;">It Helps Prevent Breakdowns</h3> <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;">Regular maintenance can spot potential problems and get them sorted before you're left stuck without climate control on a stinking hot day or a freezing cold night. It's a lot cheaper and less hassle to prevent problems than to fix them once they've happened. <h3 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;">It Prolongs the Life of Your Unit</h3> <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;">Frequent maintenance can extend the lifespan of your heating and cooling system. Like a meticulously serviced engine, it promises to function efficiently for a long haul. <h3 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;">It Keeps You in Warranty</h3> <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 lot of manufacturers require regular maintenance to keep the warranty valid. You'd want to avoid voiding your warranty for lack of looking after your investment well. <h2 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;">Choosing the Right Professionals</h2> <img src="https://oversixtydev.blob.core.windows.net/media/2023/12/HeatingCooling04.jpg" alt="" width="1280" height="720" /> <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 air conditioning installation, repairs, and maintenance, make sure you're seeking out the right professionals.

5 tips for getting off gas at home – for a cleaner, cheaper, healthier all-electric future

<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/nicola-willand-441807">Nicola Willand</a>, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a> 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>. 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. 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. 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. <figure><iframe src="https://www.youtube.com/embed/2JuZgXz6zNo?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption>Homes must switch away from gas by 2050, says policy think tank (ABC News)</figcaption></figure> <h2>Tip 1 – Find trusted, independent information</h2> 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>. 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. 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. The <a href="https://www.facebook.com/groups/MyEfficientElectricHome">My Efficient Electric Home</a> group on Facebook is another active and helpful forum. 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>. <h2>Tip 2 – Plan your approach</h2> 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. There are three main ways to go all-electric: <ul> <li> Replace all your gas appliances at once. 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. </li> <li> Replace your gas appliances one at a time, 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. </li> <li> Just stop using gas appliances 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. </li> </ul> You could even borrow portable appliances to see how they work before committing to buying your own. <figure><iframe src="https://www.youtube.com/embed/tLjWZicC4mE?wmode=transparent&start=2" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption>Households share their electrification journey (Renew)</figcaption></figure> <h2>Tip 3 – Access available rebates and resources</h2> 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: <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> 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. <h2>Tip 4 – Wait for a sale or negotiate a better deal</h2> 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. <h2>Tip 5 – Know the issues</h2> While the shift to all-electric will likely provide many benefits there are some things you need to consider: <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> 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. 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. <img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/211261/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/trivess-moore-12580">Trivess Moore</a>, Senior Lecturer, School of Property, Construction and Project Management, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a>; <a href="https://theconversation.com/profiles/alan-pears-52">Alan Pears</a>, Senior Industry Fellow, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a>, and <a href="https://theconversation.com/profiles/nicola-willand-441807">Nicola Willand</a>, Senior Lecturer, School of Property, Construction and Project Management, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Choosing the best LED lighting for your room

When it comes to illuminating your room, LED lighting has become the go-to choice for many homeowners due to its energy efficiency, versatility, and long lifespan. However, with many available options, finding the perfect LED lighting solution for your room can take time and effort. Aside from enhancing safety and security, incorporating an <a href="https://www.metropolitanelectrical.com.au/blog/led-lighting-for-outdoor-spaces-safety-and-security/" target="_blank" rel="noopener">LED light in outdoor spaces</a> and creating a well-lit and inviting area inside your room is equally crucial to meeting your needs and preferences. LED lighting provides the perfect solution to achieve a warm and cosy ambience while offering energy efficiency and long-lasting performance. You can transform your room into a comfortable and visually appealing haven by carefully selecting the right LED fixtures and considering essential factors. 1. Assess Your Room's Requirements The first step in choosing the best LED lighting is to assess your room's specific requirements. Consider the size of the room, its purpose, and the existing lighting setup. Identify areas that require more illumination and softer lighting for a cosy ambience. 2. Determine the Lighting Type LED lighting comes in various types, each designed to serve specific purposes. Some common types include: Ambient Lighting Ambient lighting provides overall illumination and sets the mood of the room. Choose LED fixtures like ceiling lights or wall-mounted fixtures that offer a wide dispersion of light. Task Lighting Task lighting is essential for focused activities such as reading, working, or grooming. LED desk lamps or under-cabinet LED strips are ideal choices for task lighting. Accent Lighting Accent lighting helps create visual interest and highlights specific features in the room, such as artwork or architectural elements. LED spotlights or track lights work best for accent lighting. <img src="https://oversixtydev.blob.core.windows.net/media/2023/08/Choosing-the-Best-LED-Lighting-for-Your-Room02.jpg" alt="" width="1280" height="1022" /> 3. Consider Colour Temperature LED lights are available in different colour temperatures, measured in Kelvin (K). Lower values like 2700K-3000K produce warm white light suitable for living rooms and bedrooms, while higher values like 5000K-6500K provide cooler white light more ideal for task-oriented areas like kitchens and workspaces. 4. Energy Efficiency One of the significant advantages of LED lighting is its energy efficiency. Look for LED bulbs with the ENERGY STAR label, as they meet strict energy efficiency guidelines and can significantly reduce your energy consumption. 5. Check the Lumens Lumens measure the brightness of LED bulbs. Consider the lumens required based on the room's size and purpose. For instance, a 60-watt incandescent bulb is equivalent to approximately 800 lumens. 6. Dimmability If you prefer adjustable lighting levels, choose dimmable LED bulbs and fixtures. This feature lets you control light intensity to suit different activities and create the desired ambience. 7. Longevity and Warranty LED bulbs are known for their long lifespan, ranging from 20,000 to 50,000 hours. Additionally, reputable manufacturers often provide warranties that cover their products for several years, ensuring peace of mind. 8. Compatibility with Smart Home Systems For those looking to integrate their lighting with smart home systems, ensure that the LED bulbs you select are compatible with the preferred smart lighting technology. 9. Aesthetics and Fixture Design LED lighting comes in various shapes and sizes, including vintage filament-style bulbs or sleek modern fixtures. Consider the overall aesthetics of your room and choose LED lighting that complements the existing decor. 10. Budget Considerations While LED lighting may have higher upfront costs than traditional incandescent bulbs, remember that they save energy and last much longer, making them a cost-effective choice in the long run. 11. Sustainable Lighting Choices In this increasingly eco-conscious era, making sustainable choices is paramount to preserving our planet's well-being. Regarding lighting solutions, LED technology stands at the forefront of sustainability. Some of the environmental benefits include the following: <ul> <li>Reduced Energy Consumption</li> <li>Longevity and Durability</li> <li>Mercury-Free Lighting</li> <li>Lower Carbon Emissions</li> <li>Optimised Outdoor Lighting</li> <li>Energy Savings on a Global Scale</li> </ul> Choosing LED lighting for your room can have a far-reaching impact on the planet, making it a brighter and more sustainable place for future generations to enjoy. 12.

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

<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> 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. 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>. <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. 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. <h2>How does this ban help?</h2> 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. 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. The government appears to be offering wide support to ensure these changes happen, but this will need to be monitored closely. 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. 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. 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. <h2>Challenges of change must be managed</h2> 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. 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). 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. In addition, existing housing may face building quality and performance issues. Some may require electrical wiring upgrades as part of the transition. 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. Consumer education and modifications to appliances and buildings may be needed to increase acceptance and avoid backlash. 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. 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. 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. 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.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/210649/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/trivess-moore-12580">Trivess Moore</a>, Senior Lecturer, School of Property, Construction and Project Management, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a>; <a href="https://theconversation.com/profiles/alan-pears-52">Alan Pears</a>, Senior Industry Fellow, <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>, Associate Professor, Sustainability and Urban Planning, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

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

<a href="https://theconversation.com/profiles/esther-suckling-1220357">Esther Suckling</a>, <a href="https://theconversation.com/institutions/grattan-institute-1168">Grattan Institute</a> 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. 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. 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. But many households face hurdles that stop them, or make it hard for them, to go all-electric. Governments could make it easier for people and bring emissions-reduction targets closer to reality. <h2>Most households save by upgrading to electric</h2> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/532139/original/file-20230615-29-h20bv5.png?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/532139/original/file-20230615-29-h20bv5.png?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/532139/original/file-20230615-29-h20bv5.png?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=393&fit=crop&dpr=1 600w, https://images.theconversation.com/files/532139/original/file-20230615-29-h20bv5.png?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=393&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/532139/original/file-20230615-29-h20bv5.png?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=393&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/532139/original/file-20230615-29-h20bv5.png?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=493&fit=crop&dpr=1 754w, https://images.theconversation.com/files/532139/original/file-20230615-29-h20bv5.png?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=493&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/532139/original/file-20230615-29-h20bv5.png?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=493&fit=crop&dpr=3 2262w" alt="A chart showing estimated savings for each household switching from gas to electricity, over 10 years, in each capital city" /></a><figcaption>Over 10 years, the estimated savings for each household switching from gas to electricity range up to $13,900 in Melbourne. It’s a flat $3,890 figure for Brisbane, rather than a range, because there’s no gas heating. Grattan Institute, Author provided</figcaption></figure> 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. 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. 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>. <h2>Households face a series of hurdles</h2> 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. 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. 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. 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. <h2>Here’s how governments can help</h2> 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. 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. 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. 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. 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. 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%. <figure><iframe src="https://www.youtube.com/embed/K9ytSh5TM9M?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption>Induction cooking with Chef David Wei at Ginninderry.</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&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/532117/original/file-20230615-23-n0wdqe.png?ixlib=rb-1.1.0&q=45&auto=format&w=754&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&q=45&auto=format&w=600&h=572&fit=crop&dpr=1 600w, https://images.theconversation.com/files/532117/original/file-20230615-23-n0wdqe.png?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=572&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/532117/original/file-20230615-23-n0wdqe.png?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=572&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/532117/original/file-20230615-23-n0wdqe.png?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=719&fit=crop&dpr=1 754w, https://images.theconversation.com/files/532117/original/file-20230615-23-n0wdqe.png?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=719&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/532117/original/file-20230615-23-n0wdqe.png?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=719&fit=crop&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>Hydrogen is more expensive than electricity and will remain so for decades. Grattan Institute, Author provided</figcaption></figure> 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. 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. Meanwhile, more than three million Australian homes already run on electricity alone.

An El Niño looms over Australia’s stressed electricity system – and we must plan for the worst

<a href="https://theconversation.com/profiles/dylan-mcconnell-1602">Dylan McConnell</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a> and <a href="https://theconversation.com/profiles/iain-macgill-576">Iain MacGill</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a> The Bureau of Meteorology this week declared a 70% chance of an <a href="https://media.bom.gov.au/releases/1170/the-bureau-of-meteorology-issues-an-el-nino-alert/">El Niño</a> developing this year. It’s bad timing for the electricity sector, and means Australians may face supply disruptions and volatile prices. <a href="http://www.bom.gov.au/climate/updates/articles/a008-el-nino-and-australia.shtml">El Niño events</a> are <a href="https://theconversation.com/from-floods-to-fire-a-climate-scientist-on-the-chances-el-nino-will-hit-australia-this-year-197408">associated with</a> increased temperatures and heatwaves. These conditions drive demand for electricity, especially in summer. These same conditions can also mean some generators don’t produce at full capacity. And unfortunately, the likely El Niño comes as the electricity sector grapples with other significant headwinds. Australia’s electricity grid may be fine this summer. But given what’s on the horizon, it would be prudent to plan for the worst. <h2>How does hot weather affect energy supplies?</h2> Increased air conditioning use in summer can cause <a href="https://aemo.com.au/-/media/files/electricity/nem/planning_and_forecasting/nem_esoo/2022/forecasting-approach-electricity-demand-forecasting-methodology.pdf">demand to peak</a>, particularly during heatwaves, as the below graph shows. <figure class="align-center "><img src="https://images.theconversation.com/files/530604/original/file-20230607-27-m1kddg.png?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/530604/original/file-20230607-27-m1kddg.png?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=208&fit=crop&dpr=1 600w, https://images.theconversation.com/files/530604/original/file-20230607-27-m1kddg.png?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=208&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/530604/original/file-20230607-27-m1kddg.png?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=208&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/530604/original/file-20230607-27-m1kddg.png?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=262&fit=crop&dpr=1 754w, https://images.theconversation.com/files/530604/original/file-20230607-27-m1kddg.png?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=262&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/530604/original/file-20230607-27-m1kddg.png?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=262&fit=crop&dpr=3 2262w" alt="Scatterplot of New South Wales demand and temperature, example based on 2017 calendar year" /><figcaption>Scatterplot of New South Wales demand and temperature, example based on 2017 calendar year. AEMO</figcaption></figure> At the same time, electricity generators – including coal, gas, <a href="https://www.climatechangeinaustralia.gov.au/en/projects/esci/esci-case-studies/case-study-heat/">solar and wind</a> – can become less efficient in hot temperatures, and so provide less energy to the system. And the hotter transmission lines get, the less electrical current they can safely carry. This lowers their capacity to transport energy. When the electricity grid is under stress, this can lead to “load shedding” or blackouts – when power companies deliberately switch off the power supply to groups of customers to prevent the overall system from becoming dangerously unstable. This happened in Victoria in early 2019, when more than <a href="https://www.abc.net.au/news/2019-01-26/victorian-blackouts-what-caused-them-and-is-this-the-new-normal/10751412">200,000 customers</a> lost power during a period of extreme heat. El Niño events are also associated with reduced rainfall. Among other effects on the electricity grid, this can reduce output from hydroelectricity generators (which produce electricity by pumping water through turbines). This <a href="https://theconversation.com/praying-for-rain-50085">occurred</a> in Tasmania in 2016, and contributed to an energy crisis in that state. <h2>Other headwinds are blowing</h2> Aside from facing a likely El Niño, the electricity sector faces other headaches. Earlier this year, the Australian Energy Market Operator <a href="https://aemo.com.au/newsroom/media-release/aemo-issues-nem-reliability-update">warned</a> electricity demand “may exceed supply” at times over the next decade due to factors such as weather conditions or generator outages. The market operator pointed to delays to the Snowy 2.0 hydro project and the gas-fired <a href="https://www.afr.com/companies/energy/new-snowy-ceo-can-t-rule-out-further-delays-at-projects-20230213-p5cjzr">Kurri Kurri Power Station</a>, both in New South Wales. The Kurri Kurri project has been delayed for a year. It was scheduled to begin operating in December this year – in time for the first summer since the Liddell coal-fired power station closed. The Australian Energy Market Operator said the electricity system was expected to meet the “reliability standard” in all regions for the next five years. The <a href="https://www.aemc.gov.au/energy-system/electricity/electricity-system/reliability#:%7E:text=What%20is%20the%20Reliability%20Standard,to%20be%20met%20each%20year.">standard requires</a> at least 99.998% of forecast demand be met each year. Unmet demand can lead to interrupted supply, or blackouts. But the operator also said delays to the Kurri Kurri project posed risks to reliability in NSW this summer. Adding to the pressures on the system, Queensland’s Callide C coal-fired power station is still not back to capacity more than two years after an explosion at the site. The station’s owners last week <a href="https://www.afr.com/companies/energy/energy-grid-fears-as-callide-c-return-delayed-until-mid-2024-20230529-p5dc90">announced</a> the plant would not be fully operational until mid-2024. Combine all this with a likely El Niño, and the electricity sector may be facing a challenging summer. <h2>El Niño years are not normal</h2> In August, the Australian Energy Market Operator is due to publish a new <a href="https://aemo.com.au/-/media/files/electricity/nem/planning_and_forecasting/nem_esoo/2022/esoo-and-reliability-forecast-methodology-document-2022.pdf">assessment</a> of the grid’s expected reliability over the next decade. It may well show reliability standards will be achieved. On first blush, that sounds like good news. However, the way the assessment is derived may mask the real risk during El Niño periods. The assessment combines a number of scenarios, which are based on different <a href="https://aemo.com.au/en/energy-systems/electricity/national-electricity-market-nem/nem-forecasting-and-planning/forecasting-and-reliability/projected-assessment-of-system-adequacy">forecasts</a> of electricity demand. The scenarios based on average weather conditions are given the most weight. But if an El Niño arrives, this summer will not be average. We’re likely to experience very hot and dry conditions. This may lead to higher demands on the energy system, and a greater likelihood of blackouts. This won’t be properly reflected in the assessment. So the grid may be deemed reliable even though electricity supplies are under immense pressure. <figure class="align-center "><img src="https://images.theconversation.com/files/530771/original/file-20230608-30-lb28wc.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/530771/original/file-20230608-30-lb28wc.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=450&fit=crop&dpr=1 600w, https://images.theconversation.com/files/530771/original/file-20230608-30-lb28wc.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=450&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/530771/original/file-20230608-30-lb28wc.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=450&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/530771/original/file-20230608-30-lb28wc.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=566&fit=crop&dpr=1 754w, https://images.theconversation.com/files/530771/original/file-20230608-30-lb28wc.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=566&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/530771/original/file-20230608-30-lb28wc.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=566&fit=crop&dpr=3 2262w" alt="repair person climbs power pole" /><figcaption>The grid may be deemed reliable even though it’s under pressure. Shutterstock</figcaption></figure> <h2>What can be done?</h2> You might find all this news worrying. But there are measures and technologies in place to help reduce the risks. <a href="https://aemo.com.au/en/energy-systems/electricity/emergency-management/reliability-and-emergency-reserve-trader-rert">A mechanism</a> exists that allows the market operator to secure emergency energy reserves. It could mean, for example, calling on a large industrial plant to pause operations to reduce its electricity use, or starting up a standby diesel generator. The operator can start procuring this months ahead of time, and will no doubt be monitoring the situation closely. In the medium term, the uptake of so-called “consumer energy resources” such as rooftop solar farms and small-scale battery storage shows promise. These technologies are located at homes and businesses. They can reduce demand on the grid at peak times and can potentially be built faster than big projects. Longer term, we need to build more “stuff”. This includes renewable energy and other “dispatchable” resources – which can provide energy when it’s needed – as well as more transmission infrastructure. Several federal funding measures – the <a href="https://www.energy.gov.au/government-priorities/energy-supply/capacity-investment-scheme">Capacity Investment Scheme</a> and <a href="https://www.energy.gov.au/news-media/news/rewiring-nation-supports-its-first-two-transmission-projects">Rewiring the Nation</a> – might help realise these projects. The reality is that ageing coal plants are closing – and while they remain open, they’re contributing to reliability challenges in the energy system. Unchecked climate change will also add considerable strain, through natural disasters and more extreme weather. Unfortunately, investment in renewable and other low-emission technology has been <a href="https://www.cleanenergycouncil.org.au/news/clean-energy-construction-peaks-as-investment-pipeline-battles-headwinds">slower than necessary</a>. This has slowed Australia’s emissions reduction efforts and cast questions over the reliability of our energy supplies as an El Niño looms.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/207210/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/dylan-mcconnell-1602">Dylan McConnell</a>, Senior Research Associate, Renewable Energy & Energy Systems Analyst, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a> and <a href="https://theconversation.com/profiles/iain-macgill-576">Iain MacGill</a>, Joint director, Collaboration on Energy and Environmental Markets, and Professor, School of Electrical Engineering and Telecommunications, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a> This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Electric blankets can be a convenient alternative to switching on your heating system. They typically consume between 100 to 150 watts, which makes them an energy-efficient solution for most people who want to stay warm during the colder months. Are electric blankets waterproof? Most electric blankets are machine washable when you disconnect the controllers. However, it's crucial that you keep the power switched off and the remote disconnected until the blanket is bone dry. And for precautionary reasons, avoid using the heat setting to quicken the drying process.

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

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. 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. 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. But where do you start? And how do you get the best bang for your buck? Here, I offer a few tips. <h2>A quick guide to home energy use</h2> Australian home energy use can be separated into a few categories: <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> 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%). This varies between states. Victoria, for example, is particularly dependent on gas. 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. 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. 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. 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. 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. <h2>So what’s the payback?</h2> 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. The payback period can vary depending on: <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> 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. Both scenarios included installation costs and $3,000 for electrical upgrades and other costs. 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. Rolled out at scale, household electrification is also a feasible way to reduce gas demand. It may be the only practical option available to decarbonise residential energy. As research <a href="https://www.sciencedirect.com/science/article/pii/S0196890422013802#b0130">recently suggested</a>, so-called “green” hydrogen – made by using low-carbon electricity to split water into hydrogen and oxygen – is unlikely to emerge as a cheap replacement for gas boilers. And why look for a technological solution to a problem we already know how to solve? 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. 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. <h2>The bigger picture for all-electric homes</h2> 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. We can work together to speed up the transition to renewable energy and reduce the demand for gas.

Explainer: Why are electricity prices expected to rise, yet again?

<div> <div class="copy"> Households in three states could be facing electricity price increases of up to 23.7% from July following a report from the Australian Energy Regulator. The increase will affect customers on standard power plans, known as the “default market offer” in South Australia, New South Wales and south-east Queensland. Small businesses could be facing price increases of between 14.7% to 25.7% depending on their location. The default market offer represents the maximum price is an electricity retailer can charge retail customers for their electricity in those states which have opted in to the system. There are around 540,000 household and 91,000 business customers in NSW, SA and Qld on the default market offer. In Victoria, an <a href="https://www.esc.vic.gov.au/electricity-and-gas/prices-tariffs-and-benchmarks/victorian-default-offer/victorian-default-offer-price-review-2023-24#toc--victorian-default-offer-2023-24-draft-decision" target="_blank" rel="noreferrer noopener">equivalent default offer</a> set by the Essential Services Commission is expected to rise by 31.1%. In Australia, energy is largely the domain of state and territory governments, and other states have different approaches. Price changes are likely to apply from 1 July 2023 to 30 June 2024. According to the Australian Energy Regulator, the <a href="https://www.aer.gov.au/news-release/default-market-offer-2023%E2%80%9324-draft-determination" target="_blank" rel="noreferrer noopener">largest factor driving the price increase</a> is the higher cost and volatility of generating electricity. In announcing the increase to the default market offer, AER Chair Clare Savage said the regulator carefully considered the need to protect consumers from unjustifiably high prices. “We know many households and businesses are already struggling with cost-of-living pressures. This is certainly a challenging environment for people to hear that further electricity price rises are on the horizon. “Energy prices are not immune from the significant challenges in the global economy right now; that’s why it’s more important than ever that we strike a balance in setting the [default market offer] to protect consumers as well as allowing retailers to continue to recover their costs and innovate. Energy Consumers Australia CEO Lynne Gallagher says the slated increases come “on top of double digit increases the previous year” and are a blow for consumers struggling with cost-of-living pressures. “These electricity price increases will hurt, heaping more pressure on household budgets and on small businesses,” she says. The default market offer represents a safety net for consumers, not the best price available. Savage and Gallagher both encouraged customers to <a href="https://www.energymadeeasy.gov.au/" target="_blank" rel="noreferrer noopener">look for a better deal from electricity retailers</a>. <h3>What does my electricity bill pay for? </h3> A <a href="https://www.accc.gov.au/regulated-infrastructure/energy/electricity-market-monitoring-inquiry-2018-25/november-2022-report" target="_blank" rel="noreferrer noopener">November 2022 report</a> by the Australian Competition and Consumer Commission says average household electricity costs comprise: <ul> <li>49% network costs (the poles and wires that deliver the electricity from power plants to consumers)</li> <li>28% wholesale costs (the cost of generating electricity from solar, wind, hydro, gas or coal-fired power stations)</li> <li>11% environmental costs</li> <li>10% retail costs</li> <li>2% electricity retailer profit margins.</li> </ul> These relative shares change over time. The Australian Energy Regulator says generation <a href="https://www.aer.gov.au/news-release/default-market-offer-2023%E2%80%9324-draft-determination" target="_blank" rel="noreferrer noopener">makes up around 30 – 40% of the price</a>, a larger share than the ACCC reports. <h3>Generation driving up costs now</h3> The cost of generating electricity – from solar, wind, gas or coal – is reflected in the wholesale energy cost. According to the energy regulator, wholesale price increases reflect higher prices for gas and coal, reliability issues with ageing coal-fired power stations and the expected closure of Liddell Power Station in NSW in April 2023. Some regional issues also affected prices, such as SA’s extreme weather in November. Energy economist Bruce Mountain is Director of the Victorian Energy Policy Centre. He says the volatile price of generating electricity is due to a range of factors. These include developments in Europe like the shift away from reliance on Russian gas which is increasing global demand for fossil fuels from other countries including Australia. Mountain says the combined demand from export contracts and local coal and gas use is higher than supply. Which is why when prices increase overseas, those higher international prices flow through into higher domestic prices. “We’ve got plentiful gas and coal, but we don’t have enough gas on our south and eastern seaboard to meet both domestic consumption and export demand,” he says. “And then on top of all of this coal and gas producers, power producers are profit-maximising. They will look for opportunities to take advantage of constraints to exercise market power.” While new renewable electricity are adding to supply, and reducing reliance on coal and gas, it’s not yet enough to counteract these effects. Mountain says the effects of higher coal and gas prices aren’t limited to fossil-fuel reliant states like Queensland, New South Wales and Victoria. Interstate connections mean electricity prices in renewable-dominated states like South Australia and Tasmania are influenced by market prices elsewhere. <h3>In the future, transmission </h3> Getting off fossil fuels might ultimately reduce generation costs and exposure to international prices for coal and gas. But Mountain expects current proposals for new major transmission lines (<a href="https://aemo.com.au/en/energy-systems/major-publications/integrated-system-plan-isp" target="_blank" rel="noreferrer noopener">connecting to new Renewable Energy Zones</a>) will “cost a fortune”, and factor in to future prices. He doesn’t believe the Integrated System Plan outlined by the Australian Energy Market Operator – involving a complete redesign of electricity infrastructure – will actually be fully implemented. “It’s of such huge magnitude, and it will have such massive implications for the environment and for landowners. I cannot imagine it’s going to be built.” Mountain says he thinks this could delay the transition to renewable energy. He says, a better, more achievable approach would be to maximise wind and solar resources as close to existing demand as possible minimising the need to build enormous transmission lines.

Why are electricity prices going up again, and will it ever end?

Households and businesses are set for more hip-pocket pain after regulators on Wednesday released draft details of electricity price rises in four Australian states. The Australian Energy Regulator <a href="https://www.aer.gov.au/news-release/default-market-offer-2023%E2%80%9324-draft-determination">revealed</a> residential customers on standard plans should brace for price increases of up to 24% in the next financial year. The price rises apply to households in Queensland, New South Wales and South Australia. The Victorian regulator <a href="https://www.esc.vic.gov.au/media-centre/victorian-default-offer-2023-24-draft-decision">also flagged</a> an electricity price hike of up to 30% in that state. It’s another blow in an already difficult financial situation for many, as interest rates continue to rise and inflation soars. Consumers are justified in asking: why is this happening? And is there an end in sight? <h2>The basics, explained</h2> The regulator released a draft of what’s known as the “default market offer”. It’s basically the maximum amount energy retailers can charge customers on default energy plans. So what’s a default energy plan? It’s the standard plan you’re on if you didn’t negotiate a special deal with your energy retailer, or if a deal you were on has expired. According to the ABC, <a href="https://www.abc.net.au/news/2023-03-15/australian-energy-regulator-default-market-offer/102094290">around one million</a> electricity customers in the four states mentioned above are on default market offers. Many consumers are on default plans because they don’t have the time or inclination to engage with their electricity retailer to negotiate a better deal. Others, quite understandably, find the whole process too confusing to navigate. That’s why default market offers were introduced. Both the federal and Victorian policies were developed <a href="https://www.esc.vic.gov.au/electricity-and-gas/inquiries-studies-and-reviews/electricity-and-gas-retail-markets-review-implementation-2018">after</a> <a href="https://www.accc.gov.au/media-release/accc-releases-blueprint-to-reduce-electricity-prices">reviews</a> found competition in retail electricity markets was not leading to lower prices for households or small businesses. The Victorian default offer began <a href="https://www.esc.vic.gov.au/electricity-and-gas/inquiries-studies-and-reviews/electricity-and-gas-retail-markets-review-implementation-2018">in 2019</a>. The federal measure <a href="https://www.aer.gov.au/retail-markets/guidelines-reviews/default-market-offer-prices-2023%E2%80%9324">was applied</a> <a href="https://www.aer.gov.au/retail-markets/guidelines-reviews/default-market-offer-prices-2020%E2%80%9321">in 2020</a>. The regulators release a draft determination ahead of a final decision, expected soon. <h2>So why the price hike?</h2> Your electricity bill comprises several different charges. The biggest ones are: - wholesale energy costs: the price generators such as coal and gas plants charge your retailer for the electricity delivered to you - network costs: the price charged by companies that own the “poles and wires” – transmission lines, transformers, electricity poles and the like – needed to get the electricity to your home - retail costs: the total amount needed by an electricity retailer to operate – such as issuing bills, providing customer service, marketing themselves – as well as to make a reasonable profit. Regulators calculate the default market offer by considering each of these price components. The increased default market offers are mostly due to increases in wholesale prices. Wholesale prices increased in recent months almost entirely as a result of sanctions imposed on Russia following its invasion of Ukraine. It led to a global shortage of natural gas. This was exacerbated when Russia <a href="https://www.bloomberg.com/news/articles/2022-05-31/russia-to-cut-gas-exports-to-shell-orsted-over-rubles-dispute">withdrew gas</a> supplies from the European market. Even though the energy shocks were happening half a world away from Australia, it affected domestic gas prices here. Why? Because most of Australia’s east coast gas is exported, which means its price is largely determined by the global price. This could have been avoided if the federal government has a mechanism to keep some of that gas for the domestic market – in other words, if it had a so-called “gas reservation policy”. But the current and previous governments have <a href="https://www.smh.com.au/business/companies/it-s-ridiculous-architect-of-wa-policy-calls-for-national-gas-reservation-20220616-p5au8q.html">refused</a> to implement this. The federal regulator said the planned retirement of AGL’s ageing Liddell coal-fired power station in the NSW Hunter Valley contributed to its decision. Liddell is one of the biggest coal-fired generators in the national electricity market, and the closure is likely to lead to a short-term tightening of supplies. Another factor affecting the regulators’ decision relates to a strategy electricity retailers use to protect themselves against volatile wholesale prices in future. The strategy, known as hedge contracts, <a href="https://www.aemc.gov.au/energy-system/electricity/electricity-market/spot-and-contract-markets">fixes the wholesale price</a> retailers pay for electricity over a long period – up to several years. The price set in hedge contracts struck over the past year or so was influenced by Australia’s <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/1467-8462.12492">domestic gas crisis</a> in 2022, which caused massive rises in wholesale electricity prices. <h2>What to expect down the track</h2> Australian Energy Regulator chair Clare Savage on Wednesday said the price increases <a href="https://www.abc.net.au/news/2023-03-15/australian-energy-regulator-default-market-offer/102094290">could have been much higher</a>, if not for intervention by the Albanese government late last year to cap prices in Australia’s gas and coal markets. Climate Change and Energy Minister Chris Bowen says those price caps have saved households between A$268 and $530. The caps are likely to cause further falls in the default market offer in coming years. But the policy appears to be only an interim measure until the global supply shortage eases. In the longer term, renewable energy offers a ray of hope. The federal government has set a target of 82% renewable electricity by 2030. But of course, a few significant <a href="https://www.climatecouncil.org.au/understanding-whats-next-for-australias-main-electricity-market/">complementary measures</a> – such as more investment in transmission networks and energy storage – are needed. This investment would support the transition to a zero-emissions electricity sector. Importantly, it would also insulate long-suffering consumers from volatile fossil fuel prices.

Why does lightning zigzag?

Everyone has seen lightning and marvelled at its power. But despite its frequency – about 8.6 million lightning strikes occur worldwide every day – why lightning proceeds in a series of steps from the thundercloud to the earth below has remained a mystery. There are a few textbooks on lightning, but none have explained how these “zigzags” (called steps) form, and how lightning can travel over kilometres. My <a href="https://iopscience.iop.org/article/10.1088/1361-6463/aca103" target="_blank" rel="noopener">new research</a> provides an explanation. The intense electrical fields in thunderclouds excite electrons to have enough energy to create what are known as “singlet delta oxygen molecules”. These molecules and electrons build up to create a short, highly conducting step, which lights up intensely for a millionth of a second. At the end of the step, there is a pause as the build-up happens again, followed by another bright, flashing leap. The process is repeated again and again. An increase in extreme weather events means lightning protection is increasingly important. Knowing how a lightning strike is initiated means we can work out how to better protect buildings, aeroplanes and people. Also, while the use of environmentally friendly composite materials in aircraft is improving fuel efficiency, these materials <a href="https://www.compositesworld.com/articles/lightning-strike-protection-strategies-for-composite-aircraft" target="_blank" rel="noopener">increase the risk of lightning damage</a>, so we need to look at additional protection. <h2>What leads up to a lightning strike?</h2> Lightning strikes happen when thunderclouds with an electric potential of millions of volts are connected to the earth. A current of thousands of amps flows between the ground and the sky, with a temperature of tens of thousands of degrees. Photographs of lightning reveal a host of details not observed by the naked eye. Usually there are four or five faint “leaders” coming from the cloud. These are branched and zigzag on an irregular path towards the earth. The first of these leaders to reach the earth initiates the lightning strike. The other leaders are then extinguished. Fifty years ago, high-speed photography revealed still more complexity. The leaders progress downwards from the cloud in “steps” about 50 metres long. Each step becomes bright for a millionth of a second, but then there is almost complete darkness. After a further 50 millionths of a second another step forms, at the end of the preceding step, but the previous steps remain dark. Why are there such steps? What is happening in the dark periods between steps? How can the steps be electrically connected to the cloud with no visible connection? The answers to these questions lie in understanding what happens when an energetic electron hits an oxygen molecule. If the electron has enough energy, it excites the molecule into the singlet delta state. This is a “metastable” state, which means it is not perfectly stable – but it usually doesn’t fall into a lower energy state for 45 minutes or so. Oxygen in this singlet delta state detaches electrons (required for electricity to flow) from negative oxygen ions. These ions are then replaced almost immediately by electrons (which carry a negative charge) again attaching to oxygen molecules. When more than 1% of the oxygen in the air is in the metastable state, the air can conduct electricity. So the lightning steps occur as enough of the metastable states are created to detach a significant number of electrons. During the dark part of a step, the density of metastable states and electrons is increasing. After 50 millionths of a second, the step can conduct electricity – and the electrical potential at the tip of the step increases to approximately that of the cloud, and produces a further step. The excited molecules created in previous steps form a column all the way to the cloud. The whole column is then electrically conducting, with no requirement of an electric field and little emission of light. <h2>Protecting people and property</h2> The understanding of lightning formation is important for the design of protection for buildings, aircraft and also people. While it is <a href="https://www.uwa.edu.au/study/-/media/Faculties/Science/Docs/Lightning-facts.pdf" target="_blank" rel="noopener">rare for lightning to hit people</a>, buildings are hit many times – especially tall and isolated ones. When lightning hits a tree, sap inside the tree boils and the resulting steam creates pressure, splitting open the trunk. Similarly, when lightning hits the corner of a building, water from rain that has seeped into the concrete boils. The pressure blasts off the whole corner of the building, creating the risk of deadly collapses. A lightning rod invented by Benjamin Franklin in 1752 is basically a thick fencing wire attached to the top of a building and connected to the ground. It is designed to attract lightning and earth the electric charge. By directing the flow through the wire, it saves the building from being damaged. These Franklin rods are required for tall buildings and churches today, but the uncertain factor is how many are needed on each structure. Furthermore, hundreds of structures are not protected, including shelter sheds in parks. These structures are often made from highly conductive galvanized iron, which itself attracts lightning, and supported by wooden posts. The new version of Standards Australia for lightning protection recommends such shelters be earthed.

Cheaper gas and electricity are within our grasp

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. 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. 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%. 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. Chalmers had “more work to do” and would work with the states. Here is the key step I think should be taken. To restrain electricity prices, cut gas prices 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. 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. Once those industries close, they are unlikely to return. Here’s what’s been done so far. 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. ‘Sufficient supply’ isn’t affordable supply The agreements require the supply of sufficient gas to meet the needs of east coast gas consumers. 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. 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. 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. 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. We need to be clear on two points. 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. 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. 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. Other exporters reserve gas Second, what I am suggesting is akin to what all other gas exporting countries do. 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. The gas companies need to come to the party, either to earn their “licence to operate” or to avoid the threat of export controls. 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. 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. 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.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/193388/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> Writen by Rod Sims.

5 tech mistakes not to make while travelling

In the hustle and bustle of preparing for a holiday away we sometimes forget about the small little things. We’re sure you’ve checked off all those big things you needed to do before you jet off but have you considered these simple tech mistakes people often made? We’ve rounded up the top five you’ll want to avoid to ensure your trip is easier and more enjoyable. Not backing anything up You might only be away for a week and it’s just a few hours away so it’s unlikely anything will happen, right? But what if the unexpected does happen and you lose your photos from your phone? What if your tablet gets stolen or lost? What if the memory card goes bust? Back up your phone, tablet and digital camera before you go away and if you’re holidaying for a while, it’s worthwhile to bring a USB stick to periodically back-up. Using your cell data For those going overseas, roaming rates can cost an arm and a leg. Either check if your mobile company has a reasonable international package or switch off the cellular data so your phone won’t use it. Instead limit yourself to wi-fi – most countries have public wi-fi hotspots and most accommodation usually has internet. Remember not to do anything personal on an unsecure wi-fi connection. Making calls instead of using Skype Rather than paying for international calls and texts, Skype will let you stay in touch with friends and family for free. Just make sure you’re connected to wi-fi so you’re not paying for cellular data. Stowing electronics in your check-in luggage You might be tempted to throw some of your electronics in your big luggage, after all you’re not going to be using them on the plane. But remember your check-in bag has to survive manhandling and an unpredictable luggage belt and we’ve all heard stories of items mysteriously disappearing from bags. Keep your expensive electronic with you on your carry-on. Not keeping devices close When you’ve settled into a hotel room, it’s easy to forget they’re not very secure. Think of all the people who have access to your room when you’re not in it. Even leaving valuables behind the desk can bring with it certain risks depending on the establishment you’re staying at. The best advice is to keep your electronics on you at all times. Image credits: Getty Images

Producing electricity from your sweat might be key to next wearable technology

Imagine a world where the smart watch on your wrist never ran out of charge, because it used your sweat to power itself. It sounds like science fiction but researchers have figured out how to engineer a <a href="https://cosmosmagazine.com/science/biology/bacterial-biofilm/" target="_blank" rel="noreferrer noopener">bacterial biofilm</a> to be able to produce continuous <a href="https://cosmosmagazine.com/science/electricity-from-sweaty-fingertips/">electricity fr</a><a href="https://cosmosmagazine.com/science/electricity-from-sweaty-fingertips/" target="_blank" rel="noreferrer noopener">o</a><a href="https://cosmosmagazine.com/science/electricity-from-sweaty-fingertips/">m perspiration</a>. They can harvest energy in evaporation and convert it to electricity which could revolutionise wearable electronic devices from personal medical sensors to electronics. The science is in a <a href="https://www.nature.com/articles/s41467-022-32105-6#ref-CR7" target="_blank" rel="noreferrer noopener">new study</a> published in Nature Communications. “The limiting factor of wearable electronics has always been the power supply,” says senior author Jun Yoa, professor of electrical and computer engineering at the University of Massachusetts Amherst (UMass), in the US. “Batteries run down and have to be changed or charged. They are also bulky, heavy, and uncomfortable.” But the surface of our skin is constantly moist with sweat, so a small, thin, clear and flexible biofilm worn like a Band-Aid could provide a much more convenient alternative. The biofilm is made up of a sheet of bacterial cells approximately 40 micrometres thick or about the thickness of a sheet of paper. It’s made up a genetically engineered version of the bacteria Geobacter sulfurreducens to be exact. G. sulfurreducens is a microorganism known to <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3209890/#:~:text=Interestingly%2C%20Geobacter%20sulfurreducens%20also%20called,electron%20transfer%20through%20the%20biofilms." target="_blank" rel="noreferrer noopener">produce electricity</a> and has been used previously in “<a href="https://www.nature.com/articles/s41579-019-0173-x" target="_blank" rel="noreferrer noopener">microbial fuel cells</a>”. These require the bacteria to be alive, necessitating proper care and constant feeding, but this new biofilm can work continuously because the bacteria are already dead. “It’s much more efficient,” says senior author Derek Lovley, distinguished professor of Microbiology at UMass Amherst. “We’ve simplified the process of generating electricity by radically cutting back on the amount of processing needed. “We sustainably grow the cells in a biofilm, and then use that agglomeration of cells. This cuts the energy inputs, makes everything simpler and widens the potential applications.” The process relies on evaporation-based electricity production – the <a href="https://www.nature.com/articles/s41565-018-0228-6" target="_blank" rel="noreferrer noopener">hydrovoltaic effect</a>. Water flow is driven by evaporation between the solid biofilm and the liquid water, which drives the transport of electrical charges to generate an electrical current. G. sulfurreducens colonies are grown in thin mats which are harvested and then have small circuits etched into them using a laser. Then they are sandwiched between mesh electrodes and finally sealed in a soft, sticky, breathable polymer which can be applied directly onto the skin without irritation. Initially, the researchers tested it by placing the device directly on a water surface, which produced approximately 0.45 volts of electricity continuously. When worn on sweaty skin it produced power for 18 hours, and even non-sweating skin generated a substantial electric output – indicating that the continuous low-level secretion of moisture from the skin is enough to drive the effect. “Our next step is to increase the size of our films to power more sophisticated skin-wearable electronics,” concludes Yao. The team aim to one day be able to power not only single devices, but entire electronic systems, using this biofilm. And because microorganisms can be mass produced with renewable feedstocks, it’s an exciting alternative for producing renewable materials for clean energy powered devices.  <img id="cosmos-post-tracker" style="opacity: 0; height: 1px!important; width: 1px!important; border: 0!important; position: absolute!important; z-index: -1!important;" src="https://syndication.cosmosmagazine.com/?id=200509&title=Producing+electricity+from+your+sweat+might+be+key+to+next+wearable+technology" width="1" height="1" />  <div id="contributors"> <a href="https://cosmosmagazine.com/technology/electricity-from-sweat-biofilm/" target="_blank" rel="noopener">This article</a> was originally published on <a href="https://cosmosmagazine.com" target="_blank" rel="noopener">Cosmos Magazine</a> and was written by <a href="https://cosmosmagazine.com/contributor/imma-perfetto" target="_blank" rel="noopener">Imma Perfetto</a>.

How Australia’s gig workers may remain contractors under Labor’s reforms

Uber Australia’s historic <a href="https://www.twu.com.au/wp-content/uploads/2022/06/Statement-of-Principles-28-June-2022.pdf" target="_blank" rel="noopener">agreement</a> with the Transport Workers’ Union, on the need to regulate the gig economy, is the first step in fundamental reform of gig work. It suggests the direction the Albanese government will to take to deliver better conditions for gig workers. The “statement of principles” agreed to between Uber and the union supports “regulatory certainty for platforms” and “minimum benefits and standards for platform workers who aren’t engaged as employees”. It does not agree that gig workers should be classified as employees instead of independent contractors. The response of federal workplace relations minister Tony Burke to <a href="https://ministers.dese.gov.au/burke/important-step-rights-gig-workers" target="_blank" rel="noopener">the agreement</a> suggests the government will take the same route – not changing the classification of gig workers but giving the federal industrial relations umpire, the Fair Work Commission, the power to set minimum standards for any workers in designated sectors. A precedent for this approach comes from <a href="https://www.ntc.gov.au/sites/default/files/assets/files/Safe-payments-report-October-2008.pdf" target="_blank" rel="noopener">New South Wales provisions</a> enabling regulation of payments to owner-drivers of trucks. Those provisions have been in place for more than 40 years, and have inspired the proposal <a href="https://statements.qld.gov.au/statements/95479" target="_blank" rel="noopener">before the Queensland parliament</a> to regulate the work of independent courier drivers. <h2>Leaving gig workers as contractors</h2> There are good reasons to aim to regulate gig economy workers as contractors, rather than attempting to bring them under the umbrella of being employees. Yes, their relationship with platforms can look an awful lot like an employment relationship – hence the reason for <a href="https://theconversation.com/an-employee-not-a-contractor-unfair-dismissal-ruling-against-deliveroo-is-a-big-deal-for-australias-gig-workers-161173" target="_blank" rel="noopener">court cases</a> supported by the Transport Workers’ Union seeking to have gig workers deemed employees. As the <a href="https://en.wikipedia.org/wiki/Duck_test" target="_blank" rel="noopener">saying goes</a>, if it looks, swims and quacks like a duck, it probably is a duck. But the outcome of trying to define gig workers as employees has been mixed. Around the world these attempts have sometimes <a href="https://www.theguardian.com/business/2017/feb/10/pimlico-loses-appeal-against-plumbers-worker-status-in-gig-economy-case" target="_blank" rel="noopener">succeeded</a>, <a href="https://btlaw.com/insights/blogs/currents/2018/philadelphia-u-s-district-court-determines-uber-drivers-are-independent-contractors" target="_blank" rel="noopener">sometimes not</a>. <h2>Roadblocks to becoming employees</h2> Platform companies have worked against these attempts, leveraging the fact quite a number of gig workers like to imagine themselves as <a href="https://www.cipd.co.uk/Images/to-gig-or-not-to-gig_2017-stories-from-the-modern-economy_tcm18-18955.pdf" target="_blank" rel="noopener">independent</a>, self-employed people, as well as customers’ preference for cheap services. The best (but not only) example is their success against California’s <a href="https://www.acslaw.org/expertforum/ab5-regulating-the-gig-economy-is-good-for-workers-and-democracy/" target="_blank" rel="noopener">AB5</a> law, passed in 2019, that tightened the rules for companies to hire workers as independent contractors. Uber and rival Lyft first <a href="https://calmatters.org/economy/2020/08/california-gig-work-ab5-prop-22/" target="_blank" rel="noopener">threatened to suspend operations</a> in California rather than comply with the law. They then teamed up with other platform companies such as DoorDash and spent a reported <a href="https://www.theguardian.com/commentisfree/2020/nov/12/uber-prop-22-law-drivers-ab5-gig-workers" target="_blank" rel="noopener">US$200 million</a> in 2020 to secure and a win a “ballot proposal” (known as Proposition 22) <a href="https://www.nytimes.com/2020/11/04/technology/california-uber-lyft-prop-22.html" target="_blank" rel="noopener">exempting</a> app-based transportation and delivery companies from the new law. A Californian court has since found <a href="https://www.nelp.org/blog/prop-22-unconstitutional/" target="_blank" rel="noopener">Proposition 22 unconstitutional</a>, but it remains in place pending an appeal. Even when a rule is devised to interpret the contracts that gig workers sign as employment contracts, gig companies could <a href="https://www.hcamag.com/au/specialisation/industrial-relations/uber-eats-announces-new-business-model-and-contracts-for-riders/245068" target="_blank" rel="noopener">amend their contracts</a> to get around that. But in the end, a company such as Uber will adhere, grudgingly, to most standards that are imposed on it — other than defining its workers as employees. Thus it has accepted <a href="https://www.uber.com/ca/en/drive/montreal/get-started/training-requirement/" target="_blank" rel="noopener">training requirements in Quebec</a> (after first <a href="https://www.thedrive.com/article/14652/uber-threatens-to-leave-quebec-over-new-driver-training-requirements" target="_blank" rel="noopener">threatening to quit</a> the Canadian province), <a href="https://www.masslive.com/politics/2016/08/gov_charlie_baker_signs_law_regulating_uber_and_lyft_in_massachusetts.html" target="_blank" rel="noopener">fare regulation in Massachusetts</a> and driver accreditation requirements in <a href="https://www.transport.nsw.gov.au/newsroom-and-events/media-releases/transport-for-nsw-statement-regarding-ride-sharing-apps" target="_blank" rel="noopener">several</a> <a href="https://www.intellinews.com/uber-reaches-agreement-with-the-czech-government-138071/" target="_blank" rel="noopener">jurisdictions</a>. <h2>Regulating contractors as contractors</h2> Regulating gig work without redefining gig workers as employees is not just politically easier, and hence more sustainable. It is also more effective policy. It enables regulation to be <a href="https://research-repository.griffith.edu.au/bitstream/handle/10072/405187/Peetz498000-Accepted.pdf?sequence=2&isAllowed=y" target="_blank" rel="noopener">tailored to circumstances</a>. For example it may mean applying an hourly wage rate in one sector, and a piece rate of some sort in another. For example, a New York state inquiry into how to regulate passenger transport came up with an amount expressed like taxi charges – that is, dollars per kilometre travelled – drivers needed to be paid to earn the <a href="https://news.yahoo.com/judge-rules-lyft-must-york-rules-driver-minimum-010416081.html" target="_blank" rel="noopener">equivalent of the state’s minimum wage</a> (taking into account waiting times, average speeds and so on). Different panels of the Fair Work Commission could determine different forms of gig economy regulation for different industries. Legislation does not need to specify how regulation should be expressed. It just needs to make sure that the Commission has all the power it needs, to regulate in whatever way it sees fit. <h2>Levelling the playing field</h2> The Transport Workers’ Union – which has a number of former officials in the Albanese government – has a long history of successfully promoting regulation of safety conditions for independent contractors (such as truck owner-drivers) without rebadging workers as employees. In the 1970s, for example, it persuaded the Wran government in NSW to introduce amendments to the NSW Industrial Relations Act that have made roads safer. The Albanese government does not need to legislate specific regulation. It just needs give the Fair Work Commission the power it needs to regulate in whatever way it sees fit, setting a minimum hourly rate or something else. The law must also direct the commission to set minimum standards in a way that ensures gig workers are paid as much as comparable award-covered employees, taking account of expenses. (Contractors often pay for costs that, if they were employees, would be covered by their employer.) This sort of direction is important to ensure neutrality between the costs of using employees or contractors.

Electricity retailer tells customers to leave

A small electricity retailer has told its customers to leave and find another company as they expect their prices to soar. Victorian energy supplier Electricityinabox expects its prices to increase by a whopping 95 per cent on July 1. CEO Morgan Duncan sent out a letter to all customers telling them that "only the lazy or crazy would stay" with the company. The letter begins with a straightforward statement telling customers “you need to find a new electricity provider today". "You need to be aware that smaller low price high value retailers are exiting this market. Four have already exited, some of them closed their doors," it continues. The company will continue to provide certain services but is expected to leave the electricity sector due to the increasing demand making it expensive. Energy companies ReAmped, LPE, Discover, Elysian and Future X have told customers to look elsewhere, while Momentum, Simply, Mojo, CovAU and Nectr have stopped accepting new customers. The news comes just a week after Australian Energy Market Operator (AEMO) called on Aussies to reduce their electricity consumption. Australian Energy Regulator (AER) and Australian Competition and Consumer Commission (ACCC) have warned retailers not to take advantage of the situation. Image: Shutterstock

Bunnings forced to recall electric blower

Bunnings has recalled a popular gardening tool that poses a risk of electric shock and injury. Some models of Ozito's portable electric blower are being taken off the shelves due to a defect with the impeller that can break during use and rupture the casing, releasing sharp objects at high speed and showing live parts. "Bunnings is promoting the recall of a Ozito portable Electrical Blower, model number OZBL1800WA and is green in colour, which customers were first advised about in 2015," Adrian Pearce, Bunnings general manager of merchandise, said. "Bunnings supported our supplier Ozito with their initial voluntarily recall and since then the recall has been advertised many times including on radio, print, and emails to our customers, with the current advertising designed to address any outstanding purchases made between 2009 and 2015. "Bunnings takes the safety of its customers very seriously and we encourage any remaining owners of this model to return the product to their nearest Bunnings." People who have purchased the product have been asked to stop using the blower immediately. They are encouraged to return it to their nearest Bunnings store for a full refund. For further information, customers are urged to contact Bunnings' customer relations team on 1800 811 436. Image: Bunnings

Commuters rejoice! Auckland’s first electric ferries to set sail in 2024

Two electric ferries are expected to be in the waters of Auckland by 2024 after the New Zealand government announced it would contribute $27 million in funding for the project. Minister of Energy and Resources Megan Woods made the announcement outside Auckland’s downtown ferry terminal, confirming that the funds would come from the Energy Efficiency and Conservation Authority, as reported by <a href="https://www.stuff.co.nz/environment/climate-news/128452777/government-commits-27m-for-electric-ferries-in-auckland" target="_blank" rel="noopener">Stuff</a>. The funds will also cover the majority of the project’s costs and will account for approximately 75 percent of the cost to build the two ferries. “This project will be a major boost to the rapidly developing maritime clean technology sector in New Zealand and will further upskill the maritime transport sector in New Zealand,” Ms Woods said. “This is a boost for our climate goals and our economy, which is especially vital as we continue our economic recovery from COVID-19.” With the city’s current, ageing fleet of ferries accounting for nearly seven percent of public transport journeys and about 20 percent of public transport emissions, Climate Change Minister James Shaw said the new ferries were “another important step” in working towards a low emissions future. “As a harbour city, getting around by ferry is the norm for many thousands of Auckalnders,” Mr Shaw said. “Today’s announcement means that instead of fossil fuels powering many of those journeys, people will be getting around in ways that help create a climate-friendly, prosperous future for New Zealand.” The ferries, developed by Auckland-based <a href="https://evmaritime.com/" target="_blank" rel="noopener">EV Maritime</a>, will also contribute to Auckland City Council’s commitment to halve greenhouse gas emissions by 2030, which requires transport emissions to be slashed by 64 percent. They have been developed with a range capable of covering several routes in Auckland’s inner and mid-harbour with a design similar to the electric ferry running in Wellington. Ms Woods announced the government would also be supporting 15 big businesses to move away from using fossil fuels in their production processes, providing $13 million in funding that will be matched by $32.66 million from private industry. “In partnering with the private sector through the third round of the Government Investment in Decarbonising Industry (GIDI) Fund we’re helping clean up production processes, and helping business stay ahead of the curve.” It comes just months after the first electric passenger ferry in the Southern Hemisphere <a href="https://www.stuff.co.nz/dominion-post/wellington-top-stories/127908781/electric-ferry-makes-maiden-passenger-voyage-across-wellington-harbour" target="_blank" rel="noopener">made its maiden journey</a> across Wellington’s harbour. The Ika Rere (“flying fish”) in Wellington can carry a maximum of 135 passengers - compared to the 99-person limit of its diesel predecessors - while its Auckland counterparts will seat up to 200 people.

Adding noise to electric cars for safer driving

<div class="copy"> The low-decibel motors of <a rel="noreferrer noopener" href="https://cosmosmagazine.com/technology/energy/as-the-world-surges-ahead-on-electric-vehicle-policy-the-morrison-governments-new-strategy-leaves-australia-idling-in-the-garage/" target="_blank">electric cars</a> are a blessing to many in noise-polluted cities, where poorly muffled gasoline engines can rattle nerves (and eardrums). But are they too silent? The answer, says Michael Roan, an engineering professor at Penn State University, Pennsylvania, US, is an unfortunate yes, especially for the vision impaired, who rely on their ears to detect approaching danger. In fact, Vision Australia has reported that 35% of the blind or vision impaired report being hit, or nearly hit, by electric vehicles they didn’t hear approaching. Governments are also aware of the problem, Roan says, with Australia, the US, and the EU all setting standards for how much sound electric vehicles must make. But do these standards work? To find out, Roan borrowed a Chevy Volt from General Motors and recruited 16 people, some vision impaired and some with normal vision but blindfolded, to listen to the car approaching on a quiet stretch of road. Sometimes the Volt was unmodified; other times it used speakers programmed to emit four different types of sounds, all meeting the standards. When his volunteers heard the car approaching, he asked them to push a button. When they thought it was gone, they pushed the button a second time. To make it harder, in some of the tests Roan’s team set up speakers to play background noise comparable to that in normal urban settings. Sometimes the car went 20 kilometres per hour, sometimes 10 km/h. The results were disconcerting. In general, Roan said last week in Seattle, Washington, at the 181st meeting of the Acoustical Society of America, people heard the car much better at 20 km/h than at 10 km/h—not surprising, because the faster a car goes, the more its overall sound is dominated by tyre noise. Above 20 km/h, he says, tyre noise dominates, and most cars sound pretty much alike. But at 10 km/h, he found that 20% of his volunteers would have stepped into the path of danger. Worse, in the course of 90 experimental runs, there were two in which nobody heard the car. That’s not a lot, “but when you extrapolate it to millions and millions of people, that’s a lot of people getting injured”, he says. The next step is figuring out what type of noises best reduce this risk, without being unpleasantly loud. Regulatory authorities, Roan says, have ruled against simply making the car sound like an internal combustion engine. In tests, he says, “people really didn’t like that”. Instead, they want something “more futuristic” that points to the vehicle being electric. The sounds that seem most effective at catching attention, he adds, aren’t steady whirs, but ones that change in volume or pitch. “That gets people’s attention really quickly,” he says. “[Though] their annoyance factor tends to go up, so it’s a balancing act.” Another issue is how to make this work as the green energy future fully arrives and electric vehicles are everywhere. “If there are 20 of these cars all in one area, how is that going to affect people’s detection of the one that’s most dangerous?” Roan asks. “I don’t think anyone knows that yet.” Image credits: Getty Images</div> <div id="contributors"> This article was originally published on <a rel="noopener" href="https://cosmosmagazine.com/technology/automation/adding-noise-to-electric-cars-for-safer-driving/" target="_blank">cosmosmagazine.com</a> and was written by Richard A Lovett. </div>
