Real environmentalists (like me!) have known this was coming. Solar power sounds great at small scale. When it is ramped up to the size needed to really contribute to national energy needs, it looks very ugly indeed. Ditto for wind.
Nuclear energy is the only truly environmentally friendly solution available. Especially looking ahead the huge demand electric vehicles would put on the grid.
I would say build a nuke plant in the desert, but then you have the cooling issue.
The US Navy has been producing safe Nuke power for years, I see no problem with %100 of the us power coming from nuke plants, we have plenty of trained sailors that would be happy to retire and run a power plant.
