If you're talking easily extracted oil at a reasonable price, you would need to count Canada as domestic to have any reasonable reserves.
As soon as you are trying to squeeze it out of the expensive to tap sources (deep water, etc.) it starts to look pretty thin.
The day the energy yield per dollar of production is higher for oil than for for wind/solar/natural gas/other, market forces will make the switch for us.
For now, if oil is going to continue to rise in value, why not use the cheaper Mid-east or Venezuela reserves until they are tapped out and then sell ours at the inflated future prices?
