Instapundit points us at this The Rocky Mountain News article:
But with crude oil above $66 a barrel at the close of trading Tuesday, oil shale is a promising alternative to crude. The Green River shale deposits in Colorado, Utah and Wyoming are estimated to contain 1.5 trillion to 1.8 trillion barrels of oil, and while not all of it can be recovered, half that amount is nearly triple the proven oil reserves of Saudi Arabia.
There are a lot of fossil fuel energy reserves out there. Oil shale is just one, and the difference between these other reserves and more traditional oil fields is simply the cost of recovery.
This is bad news for the alternative energy crowd, as even the more expensive oil shale (and others) is still much cheaper than solar or wind power. It is very good news for the economy and civilization in general however.
