Electric car versus hybrid – which emits less co2 – drive zero bp gas prices chicago


I’ve ordered a Hyundai Ioniq Electric and whenever I bring it up or someone asks about it, the issue of Australia’s electricity grid being so full of coal rears its ugly head. gas tax rates by state The theory is that by driving an EV all I’m doing is replacing CO2 emissions from fuel, with CO2 emissions from electricity generated by coal. I want to know if this is true in Australia in 2018, so I’ve done some basic investigation to answer the question: does driving an EV result in lower CO2 emissions than a hybrid car like a Prius? Well-to-wheel emissions

A vehicle’s CO2 emissions are more than what comes out of the tailpipe. For a hybrid, there’s the extraction, refining and distribution of petrol. That’s called “well-to-tank” emissions (i.e: an oil well to a car’s petrol tank). When combined with the emissions from the tailpipe as the petrol is combusted to make the car move, they’re called “well-to-wheel” emissions – an overview of all the CO2 emitted by the hybrid, excluding its production.

For the purposes of this comparison, I am not considering the CO2 used in the manufacture of an EV or an ICE, as various studies have shown that the vast majority of emissions from cars are a result of their use, not their manufacture. That’s not to say low CO2 manufacturing isn’t important, it’s just that over the lifetime of the car, it’s a small portion of its CO2 emissions. 76 gas station jobs The Green Vehicle Guide

The GVG generates the Lifecycle Emissions from Fuel Production via data contained in the National Greenhouse Accounts Factors. This document is produced by the Department of the Environment and contains info how much CO2 is emitted by dozens of different activities including electricity generation, oil production, oil transport, oil refining and oil storage. eseva electricity bill payment It’s not perfect, but it’s the best we have here in Australia.

The GVG takes the values in the NGAF, mushes it all together and comes up with 2436g of CO2 per L as the “well-to-tank” figure for fuel in Australia. For CO2 generated by electricity, the GVG uses a figure of 0.9kg per kWh, also compiled from the NGAF – an average of Australia’s CO2 from electricity. The GVG publishes a spreadsheet containing the current algorithm for this at the bottom of their FAQ. CO2 emitted per kilometer

If like me, you’re scratching your head and thinking how in the hell does a car using petrol emit more CO2 than a car using electricity, the answer is our grid is pathetic, and by our grid, I really mean VIC, NSW and QLD. gas x side effects liver Check out the beautiful electricityMap, where you can see in real time where our electricity comes from and how much CO2 it emits. The east coast states are all above 600g of CO2 per kWh. o gascon It’s a pathetic state of affairs. TAS & SA however, do a much better job of controlling CO2 from electricity.

What about GreenPower? Most energy retailers let you pay a bit more for your electricity per kWh and claim it is 100% renewable. electricity quiz 4th grade The government even manages and certifies it. It’s a great program and I think all EV owners should pay that little extra for GreenPower electricity, as that money goes towards your energy retailer purchasing and investing in new sources of renewable energy.

The electricity you’re supplied with from the grid is a mixture of fossil fuels and renewables – you cannot choose where your energy comes from via the grid. Adding GreenPower to your bill definitely helps to add renewables to the grid so everyone’s electricity gets a bit cleaner over time, and assauge some guilt, but even if everyone purchased GreenPower right now, that doesn’t magically make the whole grid clean overnight. electricity towers health risks An EV purchased now will get cleaner, but a Hybrid will remain dirty!

The grid is getting greener very quickly right? Which would mean soon, an EV to emit less CO2 as more renewable energy is added to the grid, whilst cars with an internal combustion engine will output the same amount of CO2 for their entire lifetimes. That’s 100% correct, but the timeframe for NSW, QLD & VIC to phase out coal is quite slow.

Does that mean nobody should buy an EV? Not at all! There are other reasons to enjoy an EV like a superior driving experience, low running costs and true zero emissions by charging from domestic rooftop solar. Supporting EVs in Australia needs to go hand in hand with harassing politicians to implement 100% renewable electricity as soon as possible!
