For all those complaining about "where the electricity comes from"...
Yes, some of it might be coming from burning coal and other fossil fuels, but those energy conversion systems are much better than what you have in your personal car engine.

A typical car engine might get 10%-50% energy conversion from gasoline to actual car movement while the rest is wasted as heat ( that's why you need to cool down your car engine! ) and mechanical waste.
Huge industrial plants on the other hand are designed for efficiency and have a much higher and constant/sustained rate of energy conversion efficiency.
Long story short, even if the energy you use for your electrical vehicle comes from a coal-burning plant, we are much better off that way than converting the fossil fuel in our personal, inefficient engines
