One thing that few people think about: until somebody can build an electric motor that is 100% efficient there will be a "cost" for running an electric motor. That cost is the inefficiency of the motor, which manifests itself as heat! So, in the end electric motors actually cause global warming!

Not with renewable power. Just completes the natural thermodynamic cycle when the power comes from wind, solar, hydro.

Right now as I post... renewables are providing over 50% of the electricity in CA. This percentage is growing every year. Zero % coal BTW. Nationwide coal is dropping every year.
