I am by no stretch of the imagination, a fan of Al Gore. But, as my old uncle used to say, 'even a blind hog finds an acorn every once in a while'.
Gore has proposed we get off carbon based sources of electricity in 10 years. I believe this is a doable goal. Gore goes on and (of course) brings politics into the proposal, but if you take the idea - no use of oil or coal or oil shale etc to produce electricity in the US within the next 10 years - it makes sense.
The list of potential power sources is extensive. Wind, geo-thermal, tidal, solar, atomic, agricultural. These things, some of which already are producing, have the potential to lower the need to import oil and slow the drain on American resources.
There was a article this AM on one of the net work news shows of a man in California with a dairy farm with 3 thousand cows. He has a system that collects methane from the lagoon where the liquid wastes are stored and this methane runs a generator to produce enough electricity to run the entire farm. Now a dairy with a 3000 cow herd uses an awful lot of power for coolers, pumps, fans, feed augers etc., and this guy is getting it for nothing except his initial investment to cover the lagoon (aboout 3 acres) and pipe the methane to the generator.
The 10 year plan has a doable goal, but we have to use imagination, innovation and determination (sounds like a Jesse Jackson speech doesn't it?

) to make it work.
