1) A great site about alternative energy production, which addresses the problem of making the windmills, panels, etc. without industrial production, is
www.otherpower.com
Hope that comes through as a link. The folks at otherpower make their own stuff. If oil disappears, there will be plenty of cars lying around for handy people to salvage the alternators from, rewire them for lower RPM, and if you can't make some kind of wind/hydro turbine out of found junk you're just not trying. Batteries are a problem, but don't forget that power doesn't have to be stored to be used. Without batteries electric power would be limited by numerous factors, but limited is better than nonexistant.
2) Personally I agree that ANWR shouldn't be drilled, but just to correct some misconceptions...it isn't pristine, drilling/exploration wouldn't hurt the caribou population any more than the existing pipeline has (not at all), and the chances that drilling would be very profitable to Alaskans are minimal. The oil companies always bring in the vast majority of their employees from Outside.
As far as buying a better brand of beer, most of the villages around the Arctic National Wildlife Refuge are dry, and alcoholism is a serious serious problem for Natives- so a different quip regarding use of potential income would be wittier and less offensive. The very minimal local hire would be Native Preference, so a statement like that comes across as unbelievably insulting even if it's not intended to be.
Just my two cents.
