Oh Can-a-da!!
That's the plan anyway. I do not believe the US has thought much beyond that.
At these prices the Canadian oil sands profitabiity is in question however and I hope our good friends to north were asked if they would please go along with it all. Without them we have no truely friendly source. Eventually someone may start asking us to maybe try not using so much. As you point out, it is truely an impressive decline and we will be facing a decision quicker then most expect.

There is an incredible article today on the Oil Drum highlighting the massive decline in Mexican oil production. You can find it here:

The article includes a chart showing the rise and fall of U.S. oil imports from Mexico. How will the U.S. replace these supplies?
