I think every form of energy has its use. Nuclear is great for submarines, because it is long-lasting, and doesn't need air for combustion. A submarine can decompose water into usable oxygen for breathing, and stay under for months, maybe years, if need be. That doesn't mean that a nuclear reactor is the best idea for every person's house. Solar is wonderful for this sort of thing, both to heat water, and generate electricity. It's not cost-effective for everyone now, but the idea of both candidates is that solar would be encouraged by incentives. Obama's support of solar is somewhat easier to believe, as he's no friend of Big Oil. As far as China not being interested in solar, I've heard quite the opposite. They're hungry for all forms of energy, solar included. At the Olympics, panels from one of their domestic manufacturers, Suntech, powered some of the displays.
