Hear is a good resource of information on various forms of energy sources. It is produced by a pronuclear site but offers some good information about the different forms of energy generation now available.
Their Conclusion:
"Throughout the world, we need every energy source we can get - including nuclear. As one can see from the table above, all energy sources have BOTH advantages AND disadvantages. Nuclear has a number of advantages that warrant its use as one of the many methods of supplying an energy-demanding world. Even with conservation efforts, energy demand has been and will continue to increase. Other factors can accelerate that increase, e.g. the proposed shift to electric cars to meet environmental air quality goals. In using each and every one of these forms of energy production, we need to make sure we conserve as much as we can so we leave sources for future generations. Energy suppliers need to ensure that they do not contribute to short and long-term environmental problems. Governments need to ensure energy is generated safely to that neither people nor the environment are harmed.
In the United States, many of the existing nuclear plants will reach the end of their currently authorized U.S. Nuclear Regulatory Commission license during the next 25 years. If nuclear is not used, other energy sources must be obtained."
