My own fetish has always been family sized power packs, solar (urban) plus wind (urban and rural) or whatever; problem (aside from cost) has always been what to do during down times (batteries).
Oh yeah: Electric cars are a dead end unless and until they are capable of charging themselves. Which, of course, will require some other means of power while the batteries are being built back up. And while new nuclear generating plants are being debated by powers that be.
