Yeah, but there's a companion angle to this. Carr explains well in "The Big Switch" about why centrally generated power made economic sense. But it only made sense just because the technology catered to that solution. It may be the case that, as with computer technology, market and materials drive costs of solar technology to zero. Then you might have peer cooperatives set up for sharing the load of home power consumption. Panels might become so cheap that whole neighborhoods go off the grid, or install their own distribution system. Decentralization of power generation becomes more economical than centralized power generation. I watched some alternative energy documentary one time that had one of the contributors suggesting that half of all the roofs in Cali would have to be covered with panels to take care of the state's power needs. Uh well, ok.
