With all these articles about global warming, I thought I'd throw out the theory of peak oil. The theory is that the world has reached or is about to reach it's maximum capacity to produce oil. If this is in fact true, all these problems of global warming may be a moot point in the not so distant future.

Here's the one statistic that leads me to believe there's a lot of truth to the theory:

Saudia Arabia has oil reserves of 262 billion barrels and they are producing around 10 million barrels a day. If you do the math it works out to 72 years of oil.

Sure there are many other areas producing oil, but Saudi seems to be the bench mark. I don't think we'll run out in 72 years, but I do think oil is going to start getting a lot more expensive when everyone realizes the easy oil is running out and we're going to have to start drilling in much more difficult areas.
