Building more nuclear plants
In a world concerned about greenhouse gas emissions and imported oil, many say nuclear power is the way to go.

Supporters of nuclear power say it produces no carbon dioxide, and the uranium comes mostly from this country or countries friendly to it. And as the number of electronic devices grows -- which could someday soon include large numbers of electric cars - supporters say expanding nuclear power is the best way to meet our energy needs.

But detractors are uneasy with nuclear power -- recalling the Chernobyl and Three Mile Island disasters of the past -- especially in an age of heightened terrorist concerns. Plus, they say there is still no long term solution for the waste, which stays radioactive for thousands of years.
