As background, my current view is that the anthropogenic signal in climate change is not significant, too much swamped by natural variability. But I live in a democracy (of sorts, anyway) and a perhaps bare majority of people are frightened, so I had hoped for nuclear power as the way. The current catastrophic situation in Japan is an absolute tragedy on many levels – one of which is that nuclear power is dead here as an option. This is very saddening for me, since the “options” of wind and solar can only supply about 35% of current demand – my country is at political risk of becoming 3rd world. Using gas is an option on the replacement basis you have noted for Colorado, but a very expensive one for Aus … about 60% of the country’s manufacturing capacity, including alumina smelters, is supplied through brown coal deposits, and these power plants are not upgradeable to gas
