There be something else we have not talked about; oil shale and tar sands.
Estimates are varied but my neighbors to the north, the Canadians, estimate that Alberta alone might have enough oil locked away in tar sands as Saudi Arabia. Of course the echo nazis declare the process to refine oil sands and oil shale emits 3 times as much green house gases as regular oil does. The good old USA has a lot of oil shale. Tar sands and oil shale were looked at after the Middle East shut off oil to the West. It is expensive to process the stuff, but estimates in Canada say it costs $18 a barrel to refine tar sands. With oil above $140, its game on.
Once again this is a market driven solution. I can see lawsuits and government hindering this solution just like off shore drilling which a democratic controlled congress won't pass.
here be some sources from the news that support my claims
