A power plan for the US

Bob Cringely proposes an upgrade to the US grid as well as a moratorium on incandescent light. Not sure about the underlying statistics, but I have always wondered about the puny 110V and ancient (often spaghetti) cabling found even in affluent neighborhoods over there. Not to mention the efficiency loss from the thin copper. 18% less power use? On the surface, this seems like a good idea to me.
