About 60% of electricity in the US comes from fossil fuels, today. About 30% of that comes from natural gas, which is very clean when compared to the other sources. Nuclear could provide all our needs, but it's hard to get them up and running due to how people feel about them. 15 years from now solar energy will probably cost about 10% of what it does today because of nanotechnology, solar paint and other breakthroughs. Clean electricity is the future.
