Wall Street Journal (or was it business week?) said recently that world oil production will historically peak at thanksgiving this year and will (decline) never be as high again. It went on to state that recent exploration (discoveries) for new oil is coming up empty in most cases.
Because of the added and increasing demand China is placing on the worlds resources, we may be in dire straits in the 'very' near future (it said) . And it said most experts are agreeing.
Fewer 'other' experts are countering and saying we have another generation worth of oil.
I don't think another generation ( best case scenario - 2 or 3 decades) is a long time (not long enough to be still dickering with the internal combustion engine). One thing I agree with Al Gore on- "The internal combustion engine is the scourge of the 20th century".
