$4+/gallon is obviously not painful enough. If it were then we’d have the national will to bring out hydrogen fuel cells for commercial use. Or put up solar cells over 3 or 4 Nevada counties and provide electricity to power everything we need in this country. It’s true, just a few desert counties (small counties too, added together about the size of San Diego county + a little bit of Imperial) and we would be able to meet all of our energy needs from a domestic, non-carbon producing, non emissions emitting energy source – we’d just have to put up with those ugly transmission lines – NIMBY!!! Unfortunately, as noted above, it’s a matter of national will. The only thing resembling a national will in the few years is to get and spend a HELOC as quickly as possible.
