- Overall, the (US) electricity mix is lower-emitting than gasoline.
- The US electricity mix is trending greener. (Gasoline cars are also getting more efficient, but many of those changes also apply to electric cars)
- The electricity sector is easier to move than automobiles. We’ve already seen a couple of major shifts (coal->nat gas->renewables), while we’re still very slow on the first big paradigm shift for cars.

It’s worth remembering that this does have the effect of concentrating pollution. If a coal plant opens near you, that might be worse on your health than even a broad change to EVs. Happily, nobody is really building much coal anymore, and natgas/renewables are much better for air quality than either coal plants or gasoline engines.
Anyway, it seems patently obvious that a massive coal power plant should be cleaner per unit of energy than a janky disposable ICE powerplant shoved under the hood of a cheap little mass-produced car.
I'm not sure it's entirely worth your time to engage with intellectually un-curious people not capable of thinking in shades of grey.
But the catch here is that when the politicians get their shit together and more to more renewable and less polluting methods of electricity production, suddenly ALL EVs in use will instantly become less polluting.
ICE cars don't mysteriously grow new particle filters or catalytic converters with a free OTA update. They pollute the same amount (or more) for their whole existence.
