Steven Chu, Obama's energy secretary, has called coal plants his "worst nightmare."
He is the head of the national research lab in Berkley, Ca, and put together a thorough tech-oriented overview of the climate, CO2, and energy problem. He is quite obviously a very intelligent fellow and, based on the style of his powerpoint presentation alone, much more of a thinker than a politician. He is a physicist rather than an engineer, though, so I'm a bit concerned about how capable he is of balancing reality against theory.
As energy secretary, he will preside over a nation that gets roughly half of it's electricity from his worst nightmare. And his favorite new energy supply option? Conservation. In a close second, though, come my favorites of wind/EVs and a new layer of high voltage DC power transmission lines.
