Carlo: Nuclear is one option, but I am not so sure it's the only one. For
example, Denmark right now generates 15% of their electricity with wind
factories.

Of course, wind and solar, which are true renewable sources of energy, should
be used wherever they are feasible. But, NIMBYs aside, the resulting
electricity cannot power reciprocating engines. Hydrogen can, but it takes lots
of energy to make it. The only feasible way is to use electricity -- the
electrolysis method. But then, again, it would take a lot of electrical energy.
Thus the only source of seemingly unlimited electricity is from a breeder
reactor. Even for a conventional reactor there is something like 500 year's
worth of uranium available. But the breeder would take care of the waste
problem, too.

The electrolysis method, which is certainly better than the negative result of
converting methane, requires water, another commodity that is getting scare.
There is, in Florida I believe, an experimental site that is mating a
desalinating plant with a nuke power plant. The possibilities there seem
endless. Between sea water and nuclear energy, all the water and energy needs
of the world could be fulfilled.
