Suppose the leaders of this country were wise enough to put a moratorium on traditional coal (the most urgent climate policy needed, as discussed here)? How will we meet our steadily growing demand for carbon-free power over the next decade? And to get on the 450 ppm path, we don't just need to stop U.S. emissions from rising -- we should return to 1990 levels (or lower) by 2020.
Nuclear
Nuclear is an obvious possibility, beloved of conservative Francophiles like McCain and Gingrich, but energy realists understand that it is very unlikely new nuclear plants could deliver many kilowatt-hours of electricity by 2018, let alone affordable kwh. Indeed, back in August, Tulsa World reported:
American Electric Power Co. isn't planning to build any new nuclear power plants because delays will push operational starts to 2020, CEO Michael Morris said Tuesday ...
Builders would also have to queue for certain parts and face "realistic" costs of about $4,000 a kilowatt, he said ...
"I'm not convinced we'll see a new nuclear station before probably the 2020 timeline," Morris said.
And that in spite of the amazing subsidies and huge loan guarantees for nuclear power in the 2005 energy bill (see here).
