Uncache economic liberal dogma and consider real world experience for a moment? Because just going from observation, I would have to say that Electric Grids do in fact work better when centrally planned. TVA, EDF and the rest of the regulated utilities beat the stuffing out of every example of places that attempt to have competitive markets in electricity. That said, if we actually cared about the problems of fossil fuels, we would long ago have transitioned to a fission based grid, because that would actually solve that problem.
