Al Gore lays down green challenge to America

[Hog1]

IMO, we need to promote a more balanced portfolio of energy sources in this country (as has already been touted in your article). Naturally, that would relieve some, and hopefully enough of the dependence on petroleum. Diversity, I believe is the answer. If any one thing goes South, we have the other sources to fall back on. It should allow us to back off from foreign suppliers, and use our own production. The appropriate technology in the appropriate places, as not everything will work everywhere.
AND, T. Boone Pickens is not an idiot. I have some info someone emailed me, but it is lengthy and I have not read it yet.
For what it's worth, I am investigating alternatives for myself (as in converting my vehicles I currently have).
Possibly, the bio-diesel, Hydrogen, and Propane assist to determine if it's just smoke and mirrors, or has some merit.
