There isn't any poltical power to be had in an energy abundance.
The word "scarcity" is often seen with the word "managed" in front of it. There's a reason for this. If there's plenty of clean power to go around, why would we need the overlords controlling our lives?
When it was looking like cold fusion was going to work for a little while back there, the "small is beautiful" contingent of environmentalists had a cow.
These people don't WANT a solution that will stop pollution, yet allow people to drive big cars and have hot tubs in the back yard. The idea of national energy rationing gives them a stiffy you could cut glass with.
