And, as, always, glosses over the fact that even if EVs are simply just equivalent to ICE vehicles, moving a million point sources of pollution (cars) to a small number of single point sources (power plants) makes the pollution problem much easier to solve and improves the air quality in cities dramatically.

One number I challenge, though, is "0-4% for auxiliary use". My AC on an EV looks to be closer to 15% of cruising energy in a hot clime, and I know that my ICE cars always had a significant drop in MPG when I ran the AC, too. In addition, heating is "free" in an ICE car while it's probably a similar 15% in an EV car.

It would also be easier to solve if we moved from millions of consumers (cars) to 10000s (trains). And we wouldn't even need batteries. That is even less talked about.

I wonder if there are any EVs that combine the battery cooling system with the heater! There is still some waste heat in an EV though I don’t know if it’s being well utilized yet.

And EVs in cold climates heat the batteries.
