End of the world as we know it

You might feel fine, but high oil cost, scarcity mean American Empire is about to come crashing down

Peak oil spells the end of civilization. And, if it's not already too late, perhaps it will prevent the extinction of our species.

M. King Hubbert, a petroleum geologist employed by Shell Oil Co., described peak oil in 1956. Production of crude oil, like the production of many non-renewable resources, follows a bell-shaped curve. The top of the curve is termed "peak oil," or "Hubbert's peak," and it represents the halfway point for production.

The bell-shaped curve applies at all levels, from field to country to planet. After discovery, production ramps up relatively quickly. But when the light, sweet crude on top of the field runs out, increased energy and expense are required to extract the underlying heavy, sour crude. At some point, the energy required to extract a barrel of oil exceeds the energy contained in barrel of oil, so the pumps shut down.

Most of the world's oil pumps are about to shut down.

We have sufficient supply to keep the world running for 30 years or so, at the current level of demand. But that's irrelevant because the days of inexpensive oil are behind us. And the American Empire absolutely demands cheap oil. Never mind the 3,000-mile Caesar salad to which we've become accustomed. Cheap oil forms the basis for the 12,000-mile supply chain underlying the "just-in-time" delivery of plastic toys from China.
