any semi-educated person who builds a house or commercial building without some thought to solar etc. is to stupid to be even given a permit. Even 20 years ago the high school drafting classes in a Maine high school I worked at couldn't turn in a non-solar project....Anyone capable financially of some retrofitting who doesn't is just irresponsible, especially as they wail about the oil companies. The oil companies undoubtedly will ride this monster as long as they can, but of course they have plans for all kinds of alternative energies..ready to roll out at a moment's notice.
