Which is worse for the environment: driving an average car powered by gasoline, or driving an electric car powered with electricity that was obtained by burning coal?

gasoline is worse.   the pollution in inner cities causes respiratory and health problems that aren't even accounted for properly.   Estimated 10,000s of deaths every year.

electricity need not be generated by coal, but eve  if it is, we can confine the environmental damage better, and it's easier to keep tabs on that, than emission standards for a billion cars.
