Well other sources of energy that Congress wont let us tap (because their all a bunch of evil, selfish, self-righteous sub-human pieces of garbage).

Shale Oil
Oil off of our Coastlines (Though they WONT protest that the Chinese are trying to tap it)
Coal-to-gas conversion
Liquid Natural Gas
Nuclear Power
Hydropower
Offshore Windfarms.

Yeah, Dont blame the oil companies and "Peak oil", blame those IDIOTS in Congress.
