So I was looking though some documents, with my calculator in hand (always a bad habit), and started to look into this. Assuming no other changes are made, what fraction of electricity production would have to move from fossil to nuclear for the US to meet its Kyoto target? Choices are above. More than 100% means that even if all the energy were produced from nuclear power, we still wouldn't meet the Kyoto target.

Today, 19.3% of US electricity is from nuclear.

I put more than 100% because I was thinking we would need to move a lot of non electricity energy use away from fossil to bring emissions low enough for CO2 levels to stop rising. But that's not the question. Kyoto targets aren't enough to stop CO2 levels rising.

Moving a lot of traffic that's no road or air to electric railway, & making new cars plug in hybrids would require extra nuclear electricty.

Whether Kyoto is enough is a separate issue. I needed some number to stick in, and that was as good as any. (Anothe rseparate issue is whether ratifying the treaty and not meeting your targets gives a country the right to wag its finger at countries which didn't ratify it and have come closer to their targets)

If it helps, here's another fact. To meet Kyoto would require that the carbon emissions per capita reach 1969 levels. (We might have barely hit that level during the recession of 1981-1982, but I don't think the data quality is good enough to tell. It surprised me how easy it is to see recessions on that particular plot)
