I have a bit of a problem. I am researching the topic of oil supply in the US and one thing that I need to know for my class is, if the US decided not to import any oil from outside the country, how long would our oil resources last? I would appreciate it if you could help me. I have been searching the internet and found all of the other information I need but this question has not been touched upon. Thank you.

Good question! I'm not surprised that you've had problems finding an answer. It seems easy enough to calculate when the US would run out of oil: just take proven reserves and divide by annual consumption. If we take one expert's figures - consumption of about 7 billion barrels a year, proved reserves of 22 billion barrels - we'd run out of oil in just 3-4 years! But the calculation is clouded by a number of factors. First, you have to make assumptions about future consumption; for instance, that it will remain the same. Second, you have to make assumptions about production; history shows it cannot be maintained at the current rate (in fact, it's been in decline since 1971). Third, you have to consider the impact of alternative energy sources: wind and solar power, hydrogen fuel cells, natural gas, biomass, etc., as well as non-conventional sources of petrolelum, such as oil shales.Finally, nobody knows how much oil is out there: the oil companies are very secretive about their reserves and nobody knows how much oil awaits being discovered, particularly in the deep ocean. So, you've probably asked a question impossible to answer, and maybe not worth answering as the answer would have to be so hypothetical. I encourage you to visit the website of the Association for the Study of Peak Oil & Gas (www.peakoil.net), particularly issue #23 of their newsletter, which discusses the oil history of the United States, to learn more.
