Where I live in Ohio (and perhaps surprising to most people) there is abundant gas and oil. The local drillers say that if prices are sustained long enough above 30-35 dollars per barrel drilling here will commence (again.) This is also the case, as far as I know for Pennsylvania, Indiana, Illinois and other midwestern states. Now we add in Texas, the Gulf of Mexico and ANWAR and we just might find enough domestic production to sustain ourselves. Using up the Saudi oil first is, of course, a good conservation practice. Someday, however, it will be that the cost in dollars and political capital for Saudi oil is not worth it. When that someday will be is the question we should try to answer.
