Why can't we decentralize power generation and energy and like tehe Victory Garden of WWII, have everyone invested somehow in generating energy or else joining a coop locally that would band together and put in alternative energy and pull the rug out from under the backward looking oil monopoly of big oil in bed with crony corporatism. We should generate power locally and have many involved in supporting it. This would force the big politicians to stop pushing dead end policies.
