How long will our oil supply last?

Here's an interesting but simple math problem (from a sidebar article in Yes, current issue, p. 39):

Say we have a 100 year supply of oil at the current rate of use. If demand increases 5% per year, the oil supply will last only 36 years.

If we underestimated our oil reserves and we have instead a 1,000 year supply at current use, then how many years do we have if demand increases 5% per year? Answer: 79 years.

Say we vastly underestimated our reserves and we have 10,000 years left at the current rate of use. How many years do we have left if demand increases 5% per year? Answer: 124 years.

THIS IS PRECISELY WHY BUSH'S IDEA OF INCREASING SUPPLY BY MORE DRILLING IS A NON-STARTER.
