If we build 80 new nuclear plants per year we'd reach a stable global inventory of about 4,000 plants in about 50 years, 10 times higher than today's roughly 400 plants world-wide. A1T and B1 are two scenarios that stabilize atmospheric CO2 concentrations by 2100. http://www.grida.no/climate/ipcc_tar/wg1/figspm-5.htm In A1T, coal rises to almost double the current level in 2050, then drops to about half the current level in 2100, with the gap filled by biomass and other renewables. The nuclear power plant build-up is scheduled for the first half of the century, to be completed by 2050. In the other stabilization scenario (B1), nuclear power increases only 6-fold by 2050 consistent with construction of about 50 plants per year. It looks as though we should soon resume the 30-per-year pace of new nuclear power plant construction that was achieved during the late 1970's and early 1980's if we want to put the world on a course to stabilize atmospheric CO2 concentrations by 2100. -dl --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups Global Change ("globalchange") newsgroup.
