As you say, electric vehicles relocate pollution rather than eliminate it if the electricity is produced by a fossil fuel plant. I'm not sure I've read any estimates in overall efficiency of an electric vehicle vs an IC engine powered vehicle. Neither is very efficient.

The benefit of the electric is in improving air quality in cities where there are a lot of vehicles. I suspect, though, that many Asian cities could clean up the air a lot with the less extreme measure of replacing their many 2-stroke engine powered mopeds and scooters with machines with 4-stroke engines. The 2-strokes are very dirty, and they use considerably more gas than 4-strokes. I was in Shanghai a few years ago, and the air was blue and smelly with exhaust from the small 2-stroke bikes, and I'm sure there are cities with much worse air than Shanghai.
