I get the impression you think that electricity is automatically clean energy. Have you ever thought about how that electricity is generated? Ever heard about coal or nuclear power plants etc.? Do you think they're are environmentally friendly?
Yes, I realize that most of our electricity comes from coal, natural gas, and nuclear. However, that fact doesn't preclude the idea of using solar, wind, tidal, and geothermal energy to generate all electricity. It's much more difficult to use these energy sources to power automobiles than it is for trains.
