As for electric cars, what are you going to plug them into? A windmill? A solar cell? I can see it now, "Sorry boss, I can't make it into work today. There wasn't much wind last night and the sun hasn't been up long enough to charge my car." After all, if we follow the demands of the greenies we won't be allowed any other energy sources. Right now the electric cars are largely powered by coal fired electric plants. Sounds pretty "green" to me.
