I'm reading more and more the last year or so, that nuclear power is going to expand dramatically to meet the needs for power generation for homes and offices.  I had not realized how much power is nuclear today--78% of power provided by nuclear plants in France, 20% in the US.  I just didn't realize it was that big.  And many people make the point that it has been extremely safe--though I don't think the issue of disposal of spent rods has been adequately addressed, and of course that is a huge issue.

Transportation seems to be the problem, in the sense that their is no clear, it works now, kind of solution to replace oil.
