The Solution to Our Energy Problems: Decentralization
The great debate of alternative energy versus fossil fuels or nuclear is missing the point. The answer is decentralized energy production and storage.
As I noted last year:
A scientist has figured out how to make and store energy by splitting water with sunlight. He says: “You’ve made your house into a fuel station [and we can get] rid of all the … grids” [he's recently discovered an even cheaper way to do this]
And this TED talk gives a breathtaking overview of the potential of using nanotechnology to generate, store and distribute energy:
