How about the oil consumption today?

Royal Dutch/Shell this year downgraded its proven oil reserves by 20 per cent, or nearly 4bn barrels. Other companies and even governments have hyped up the estimates of how much oil they have. Geologists and analysts have been saying for some time that estimates of global oil reserves may be dangerously exaggerated.

Oil will not just "run out" because all oil production follows a bell curve. This is true whether we're talking about an individual field, a country, or on the planet as a whole.

Oil is increasingly plentiful on the upslope of the bell curve, increasingly scarce and expensive on the down slope. The peak of the curve coincides with the point at which the endowment of oil has been 50 percent depleted. Once the peak is passed, oil production begins to go down while cost begins to go up.

In practical and considerably oversimplified terms, this means that if 2000 was the year of global Peak Oil, worldwide oil production in the year 2020 will be the same as it was in 1980. However, the world’s population in 2020 will be both much larger (approximately twice) and much more industrialized (oil-dependent) than it was in 1980. Consequently, worldwide demand for oil will outpace worldwide production of oil by a significant margin. As a result, the price will skyrocket, oil-dependant economies will crumble, and resource wars will explode.
