Coal powered electric cars still produce 21-58% less CO2 than gasoline powered equivalent cars, according to this:
Greenhouse gas emissions

Efficiency. ICEs are 25% efficient on a good day. EVs are 80%+ efficient. A bad fuel source (coal producing electricity) with good efficiency becomes good, or at least decent, doesn't it?

Hydrogen? Horrible. 6X the CO2 of an ICE when the hydrogen is produced from natural gas, which is most hydrogen. When it's not derived from natural gas, it comes from lots of electricity + water. Where does the electricity come from? Wait for it.......COAL.
