Oil’s twilight

Forget about the price of gas for a moment. Think instead of all the oil sitting deep below the earth’s crust, waiting millions of years to be pumped to the surface, refined and used in all the ways that drive modern civilization.

That resource, scarcely touched before the dawning of the automobile age, is destined to decline. It’s a natural resource. It’s not the sun or the wind, inexhaustible and eternal for our purposes. And whether you believe the Jeremiahs or the most conservative analysts, the day is coming–faster than you may think.
