Interesting point
Chris Arnold at NPR points out that Cap-n-Trade was part of the driving force behind the recent regrowth of nuke-plant construction. Because even the green wackos finally started to understand that nukes were non-polluting, they were reluctantly allowing nukes to count as "carbon credits" for power companies.
Now that Cap-n-Trade has been turned down by Congress several years in a row, the
cost advantage of nuclear disappears, because the real cost of a nuke plant, even aside from all regulatory crap, is well above the cost of coal or natural gas. If Atmungsführerin Lisa Jackson (Heil! Heil! Heil!) manages to bring back full-fledged Cap-n-Trade through pure raw brute force, this could change again.
The real cost structure could also change when thorium-based power technology matures, but that hasn't happened yet. It won't happen here anyway, because no meaningful research happens here. That goes for everything, not just power tech.
Thorium is happening in China. From now on everything new will happen in China. America (wholly-owned subsidiary of Goldman Sachs) will only invent new financial crimes. We will continue to lead the world in innovative ways to transfer money from productive people into the Swiss bank accounts of fat Jews. We will continue to fail in everything else.
