I often hear people saying "But where does the electricity for the EV come from? Driving an EV is not better than driving a diesel."
They have to realize that the thiny ICE in your car is optimised for weight, and has an efficiency of 30-35%. So about ⅔ of the fossil fuel is turned into heat and blown out of the exhaust. Compare that to the turbine in a coal or gas plant, which can archive up to 90% efficiency.
And don't forget that an EV is an investment, which will likely still be on the road in 20 years time. The electricity mix at the moment is still rather fossil fuel heavy, but this will change completely within the next 10 years.
Edit: not 90% but 40% efficiency. See comments below
Last time I looked (a few years ago), a 100% coal powered EV had similar emissions to a 60mpg car.
I doubt anywhere will still be coal powered in a decade, with how fast plants are closing. But that EV will still be there on its 3rd owner.
Different countries and states obviously have different electricity source mixes.
Here in the UK, coal accounts for around 1% of electricity. Natural gas is about 35%, biomass about 5%, and the rest is various clean renewables (wind, solar, hydro) or nuclear.
So although charging an EV is by no means fossil-fuel-free, it's considerably less fossil-fuel than an ICE car.
That was my point. Even in the worst case it's comparable to 60mpg.... No ICE gets 60mpg. And in a decade it'll be even better.
