Nukes . . .
Nuclear has a lot of advantages, but one nasty problem . . . what to do with the waste, which is highly toxic and doesn't leave the environment for centuries. It may be part of the solution, but what we really need to focus on first is how to reduce our use of energy (any by "our" I mean that of all of us around the world . . . we in the US are by far the biggest per-captia consumers of energy and need to show far more leadership in conservation and efficiency - - - but energy consumption is growing very fast all around the world, so this needs to be addressed with global cooperation --- and there too the US needs to show more leadership).
