Leaf And Tesla S On CO2 Emissions In Australia<\/strong><\/p>\n<p>It has become clear to me there is some confusion over whether electric cars offer an environmental benefit in this country.\u00a0 Craig Kelly, who is an extremely honorable Member of Parliament, has told the nation they result in more greenhouse emissions than conventional petrol cars.<\/p>\n<p>If you are standing up while reading this you may want to sit down due to your shock when I tell you Craig Kelly is actually wrong on this.<!--more--><\/p>\n<p>When charged from the grid an electric car will result in around half the CO2 emissions per kilometer driven than the average Australian passenger car.\u00a0 When the greater emissions resulting from its manufacture are taken into account, EVs emit around one-third less per kilometer.<\/p>\n<p>But at the moment what beats <em>both<\/em> conventional petrol powered cars and electric vehicles charged from the grid is a fuel-efficient hybrid.\u00a0 Currently the most efficient model of Toyota Prius is almost certain to beat a grid charged electric car on total emissions over an average lifespan of 10+ years.\u00a0 But as Australia&#8217;s grid becomes cleaner, grid charged electric cars will eventually beat hybrids on total emissions.<\/p>\n<h2>How Much CO2 Does A Petrol Car Emit?<\/h2>\n<p>According to the Department of Environment and Energy a litre of petrol contains 629 grams of carbon<sup class='endnote'><a href='https:\/\/www.solarquotes.com.au\/blog\/electric-cars-environment-kelly\/#en-20255-1' id='enref-20255-1' onclick='return

Australian passenger car is driven around 14,000 kilometers a year this comes to around 4.8 tonnes of CO2 equivalent emissions per year.<\/p>\n<h2>Not All Petrol Powered Cars Are Equal<\/h2>\n<p>The modern internal combustion engine is a miracle of engineering and is pretty much at the limit of what can be achieved without adding an extra layer of complexity and expense to what is already an extremely sophisticated machine.\u00a0 While there are always <a href=\"http:\/\/www.autonews.com\/article\/20180128\/OEM06\/180129795\/mazda-pitches-skyactiv-3-engine-tech-to-rival-evs\" target=\"_blank\" rel=\"noopener\">reports<\/a> of new improvements that can be made to boost efficiency, not a lot is likely to come from them because the resulting price increase means it will probably make more sense to get a hybrid or go electric<sup class='endnote'><a href='https:\/\/www.solarquotes.com.au\/blog\/electric-cars-environment-kelly\/#en-20255-4' id='enref-20255-4' onclick='return hhEndnotes_show(20255)'>4<\/a><\/sup>.<\/p>\n<p>Because of this, the main way to reduce the fuel consumption of petrol powered cars is to buy a small one with low performance.\u00a0 While having a car with poor performance has little effect on our lives and is more likely to keep you out of trouble than put you in a situation where low acceleration stops you getting out of trouble, a lot of people want good performance and all electric cars capable of highway speeds (which is all of them in Australia) offer this.<\/p>\n<p>So if you get a little petrol powered car like a <a href=\"https:\/\/www.drive.com.au\/new-car-reviews\/2017-fiat-500-range-review-20170709-gx7x5l.html\" target=\"_blank\" rel=\"noopener\">Fiat Cabrino<\/a> it will burn less than half the petrol per kilometer of the average passenger car and only result in around 155 grams of emissions per kilometer, but regrettably it doesn&#8217;t have the size or performance most people are looking for.\u00a0 The proper comparison would be a small, poor performance hybrid or electric car, but they don&#8217;t really exist in this country.\u00a0 (The smaller and cheaper Prius C has worse fuel efficiency than the larger one.)\u00a0 But if it&#8217;s all you need, a small, low performance, petrol powered car can result in less emissions than an electric car such as the Nissan Leaf charged with today&#8217;s grid power.<\/p>\n<h2>How Much CO2 Does A Fuel Efficient Hybrid Emit?<\/h2>\n<p>According to the Australian Government&#8217;s <a href=\"https:\/\/www.greenvehicleguide.gov.au\/\"

average passenger car, which comes to around 107 grams per kilometer driven.\u00a0 Using the 14,000 kilometer a year average, that comes to 1.5 tonnes a year or 3.3 tonnes less than the average conventional petrol powered passenger car.<\/p>\n<p>There are a number of hybrid cars in Australia but this is the most efficient one.\u00a0 Note that while the Prius does have a battery onboard, it is only charged by the petrol motor or by braking and this model is never plugged in to charge.<\/p>\n<div id=\"attachment_20536\" style=\"width: 1010px\" class=\"wp-caption aligncenter\"><img

Nissan Leaf will need to be charged with 0.18 kilowatt-hours of electricity to drive 1 kilometer.\u00a0 On average 910 grams of CO2 are emitted for each kilowatt-hour of grid electricity consumed in

or uncomprehending.<\/p>\n<p>What the study does conclude is that manufacturing an electric vehicle in China emits 50% more greenhouse gases than manufacturing an internal combustion engine vehicle.\u00a0 It&#8217;s about cradle-to-gate emissions, which means from the start of manufacture to out the factory gate.\u00a0 I can only guess that Kelly misunderstood and thought it was cradle-to-grave, which is until the vehicle gets scrapped.<\/p>\n<p>The study found manufacturing an electric car resulted in around 5.1 tonnes more CO2 emissions<sup class='endnote'><a

China.\u00a0 Assuming the same figure applies for the Nissan Leaf manufactured in Japan, if it is charged from the grid and driven the average number of kilometers per year it will result in around 2.5 tonnes less CO2 per year than a conventional car.\u00a0 This means it will only take two years to make up for the additional emissions from its manufacture.<\/p>\n<p>The average car age in

emissions would be 63% that of the average petrol passenger car with the same lifespan.\u00a0 That&#8217;s more than one-third less.<\/p>\n<p>I hope Kelly realizes that after a mistake of this

example above I assumed the grid will remain as dirty as it is now for 12 years but, fortunately, that is not going to be the case.\u00a0 Over the past 10 years the amount of CO2 emitted per kilowatt-hour of grid electricity consumed has fallen by around 11% and this will accelerate as Australia&#8217;s aging coal power plants are shut down and replaced with renewable energy<sup class='endnote'><a href='https:\/\/www.solarquotes.com.au\/blog\/electric-cars-environment-kelly\/#en-20255-13' id='enref-20255-13' onclick='return hhEndnotes_show(20255)'>13<\/a><\/sup>.\u00a0 The next big planned closure is Liddell Power Station in 2022 and AGL is planning to mostly replace its capacity with <a href=\"https:\/\/www.solarquotes.com.au\/blog\/liddell-power-plans-mb0354\/\">renewables and demand management.<\/a><\/p>\n<h2>Batteries Will Become Cleaner<\/h2>\n<p>Battery technology has come a long way over the last 10 years and while the rate of improvement may slow, it&#8217;s not about to stop.\u00a0 Battery manufacture will become more efficient over time and the energy requirements less.\u00a0 In addition, the energy used will become cleaner as more renewable capacity is added to the world&#8217;s electricity grids.\u00a0 Hybrid cars may become more efficient in the future, but there doesn&#8217;t seem to be a lot of room for further improvements.\u00a0 At least not when it comes to burning petrol.<\/p>\n<h2>Electric Cars Will Eventually Beat Hybrids<\/h2>\n<p>For a grid charged electric car to beat a current fuel-efficient hybrid on total emissions including manufacture, the amount of CO2 emitted by grid generation would have to fall by almost half.\u00a0 If the manufacture of an electric car results in 4 tonnes more emissions than manufacturing a hybrid, then over a 12 year lifespan grid electricity emissions would have to average 54% of what they are now for a electric cars to be cleaner than hybrids.\u00a0 While I hope emissions from Australia&#8217;s electricity sector will fall by almost half within 6 years, this is not what is generally predicted.\u00a0 So it looks like a fuel efficient hybrid will beat a grid charged electric car on total emissions for years to come.<\/p>\n<h2>What If I Live In A State With Lots Of Renewables?<\/h2>\n<p>So far I&#8217;ve assumed <a href=\"https:\/\/www.solarquotes.com.au\/electric-vehicles\/\">electric cars<\/a> will be charged with grid electricity with average CO2 emissions for Australia.\u00a0 But South Australia and Tasmania both generate huge amounts of electricity from renewables.\u00a0 In Tasmania emissions from grid electricity are less than 19% of the nation&#8217;s average.\u00a0 This makes it appear an electric car would already result in less emissions than a hybrid there, but in practice this isn&#8217;t the case.<\/p>\n<p>This is because Tasmania&#8217;s grid is connected to Victoria and any clean electricity that isn&#8217;t used in state is exported to the mainland where it reduces emissions there.\u00a0 So charging your electric car in Hobart will result in greater emissions across Bass Strait.\u00a0 Because of transmission losses it will be slightly greener than charging it in Victoria, but it&#8217;s not a large difference and using a grid powered electric car in Tasmania will result in greater emissions than charging one in mostly fossil fuel powered Western Australia, which is not connected to Victoria&#8217;s extremely dirty grid.<\/p>\n<h2>What If I Charge My Car With Rooftop Solar?<\/h2>\n<p>If you have rooftop solar at the moment then the solar electricity you export to the grid is reducing emissions from fossil fuel generation.\u00a0 If you buy an electric car and start charging it with your surplus solar electricity then it will no longer be reducing emissions and so the net effect will be no better than charging it with grid electricity.\u00a0 Technically, you will only be reducing emissions if you installed extra solar capacity that you wouldn&#8217;t have got if you hadn&#8217;t bought an electric car.<\/p>\n<p>A 2018 Nissan Leaf will require around 2,500 or more kilowatt-hours to drive the annual average of 14,000 kilometers.\u00a0 For a typical Australian household this will only require around 2 kilowatts or less of north facing <a href=\"https:\/\/www.solarquotes.com.au\/panels\/cost\/\">solar panels<\/a> or less, so if you are getting solar I suggest <a href=\"https:\/\/www.solarquotes.com.au\/blog\/fill-your-roof-with-solar\/\">going big<\/a> and telling yourself those extra kilowatts are in case you get an electric car in the future.<\/p>\n<h2>Expanding Renewables Could Change Things Quickly<\/h2>\n<p>At the moment clean renewable energy almost never goes to waste<sup class='endnote'><a href='https:\/\/www.solarquotes.com.au\/blog\/electric-cars-environment-kelly\/#en-20255-14' id='enref-20255-14' onclick='return hhEndnotes_show(20255)'>14<\/a><\/sup>.\u00a0 But this could potentially change in just a few years.\u00a0 If the <a href=\"https:\/\/www.solarquotes.com.au\/blog\/sa-election-renewable-energy\/\">new SA government<\/a> doesn&#8217;t start blocking renewables it may not be that long before before periods when there is more than enough renewable electricity generated to meet demand start to become frequent.\u00a0 If and when this starts to occur electric cars can be charged with clean power that would otherwise go to waste, lowering their average emissions per kilometer and allowing them to beat fuel-efficient hybrids on emissions sooner than in other states.<\/p>\n<h2>Other Environmental Considerations Besides CO2<\/h2>\n<p>In addition to greenhouse gases, petrol and <a href=\"http:\/\/www.abc.net.au\/news\/science\/2017-04-26\/dr-karl-the-real-cost-of-air-pollution\/8472666\" target=\"_blank\" rel=\"noopener\">diesel<\/a> powered cars also spew a wide range of toxins into the air which people then suck into their lungs.\u00a0 It is estimate that vehicle pollution kills over 1,000 Australians per year.\u00a0 Last year there were under 1,300 road accident fatalities so air pollution from cars could be killing more people than car crashes and could be costing Australia over <a href=\"https:\/\/soe.environment.gov.au\/theme\/ambient-air-quality\/topic\/2016\/health-impacts-air-pollution\" target=\"_blank\" rel=\"noopener\">$10 billion<\/a> a year.<\/p>\n<p>If we assume the amount is $10 billion, then with around 1.2 million cars sold in the country each year we could spend $8,000 ensuring each new car sold is electric and the country could still come out ahead overall on cost.<sup class='endnote'><a href='https:\/\/www.solarquotes.com.au\/blog\/electric-cars-environment-kelly\/#en-20255-15' id='enref-20255-15' onclick='return hhEndnotes_show(20255)'>15<\/a><\/sup>\u00a0 Toxic vehicle pollution would be greatly reduced if fuel-efficient hybrids were used, but would not be eliminated.<\/p>\n<h2>Should I Buy A Hybrid Or An Electric Car?<\/h2>\n<p>If you buy a fuel-efficient hybrid you will be reducing your greenhouse gas emissions and exhaust toxins by far more than the average car buyer, so good on you.<\/p>\n<p>If you buy an electric car and a couple of kilowatts of rooftop solar capacity to power it, then you can drive with no emissions per kilometer and, when driven the average amount for an Australian car, you are likely to pay off the extra emissions that result from its manufacture in a little over a year.\u00a0 Also, when you drive, your car will emit zero toxins into the air we breath and you will be saving lives, provided you run over fewer people than average.<\/p>\n<p>Personally I hope you&#8217;ll take the electric car plus <a href=\"https:\/\/www.solarquotes.com.au\/solar101.html\">solar<\/a>
