U.S. energy "boom" is a bubble. Don't say you weren't warned.

Shale Bubble: "As a result of these realities – high depletion rates, the need to drill ever more wells to maintain production, decreasingly productive wells as the best locations are drilled and depleted, and the higher prices required to justify this investment – our country will have drilled and fracked our way down a blind alley (with huge associated economic and environmental costs) for a short-lived energy boom."
