Date Posted: 13:25:17 03/08/07 Thu In reply to: Bev 's message, "How green in nuclear power ?" on 10:57:37 03/08/07 Thu And to heavily use those sources we pocess here in the US. That includes Nuke, coal, oil, Nat gas, water, wind and solar. Some are better for greenhouse gases than others but we need them ALL. Technology for clean coal burning is advancing rapidly and coal can be turned to liquids. Nuke power is the best in my opinion until we get solar cost effective on large scale projects. Then that will probably be the best. Wind is great but I doubt we have enough places to build wind turbines and it would bother me to see giant wind turbines wherever I looked. But the idea there is some magic bullet that will replace all other sources is not going to happen in our lifetimes IMO. > In the meantime I came across a catalog that is >mainly aimed at the Amish people.
