FORBES: Biogas and the Shale Gas Bonanza

For gas prices to get this high on a sustained basis, you have to assume that either (a) shale gas will prove a colossal, over-hyped, mega-bust (something the Right is most definitely not in the usual business of positing) or (b) the U.S. auto-fleet will quickly transition to natural gas powered engines, driving up the demand for natural gas and, thus, the price.

One approach would peg the reserve volume to the time required in an emergency to transition the economy from natural gas to a substitute fuel.
