I just picked up a free old book about oil from the local school. It's for children and published in 1980. It explains everyhting from what oil is, to how it's extracted, refined and used. And interestingly enough it also had a chapter about the future of oil. It mentioned that by the end of the century probably only 45MB/d will be available which is less than in 1980.
Funny how they got it wrong. I'm wondering if we too, are wrong and in fact supply will climb to 100, or 120 MB/d?
