Hi I am a middle school student in Virginia. I was wondering, What info can I get on PG&E and whether the US will be using nuclear power plants in the near future?  What kind of nuclear wastes are there in the world?

     Your question is an interesting one!   Some people support nuclear power very strongly as it results in much less waste than conventional power plants powered by coal or natural gas.  The problem is that treating the waste from nuclear plants (ie. making it non-toxic) is very expensive and much of it end up being stored in placed in the desert (such as Nevada).  At this point, I don't expect the U.S. to embrace nuclear power just yet.  Nearly all of the power plants currently under construction (and there are many of them) are based on burning coal and natural gas.  Currently, nuclear power generates only about 17% of the electricity worldwide.  Some countries use it much more than the U.S.  For example, France gets about 75% of their electricity from nuclear power plants, whereas the U.S. only gets about 15% of their power from nuclear sources (this amounts to about 100 nuclear power plants in the U.S.).  For more information on this topic, see "Nuclear Power" at "How Stuff Works"
