Although they are a small percentage, nuclear and wind aren't as earth friendly as you may think. Typically when they change turbine blades, the old ones are buried on sight (due to high transportation costs I suppose). Also nuclear fuel has to be stored in a cooling bath for 10 years after it is spent (or else a meltdown could still occur like what happened in Japan a while back), and the nuclear fuel is in use for about 18 months iirc (I worked at a nuclear power plant once and was told the number, but it has been nearly 20 years).
I will say that I am surprised, yet pleased, about the solar power usage out there. I know there are programs here in Ohio to help people go solar, I would really like to with my next home.
