The US uses 20million barrels of oil a day, and that is increasing by 500k each day. IF we only used 20 million a day, and we had no increasing needs for oil, then the reserve alone would last for a little over 27 years. The thing is, it is a reserve and not a main supply. We don't have a main supply big enough to sustain everything here. If we isolated ourselves, our oil use would increase a lot due to the fact that we would have to produce so many more things for our survival. Maybe after we tap ANWR we may find there is much more oil there than once thought. I don't want to be isolated anyways, I like imported goods.
