The Greenies' Natural Gas Fracking Flip-Flop

The worldâ??s projected natural gas supplies jumped 40 percent last year. Until a decade ago, experts believed it would be technically infeasible to exploit the natural gas locked in 48 shale basins in 32 countries around the world. Then horizontal drilling, combined with hydraulic fracturing, also known as fracking, was introduced. The shale gas rush was on, and last year the U.S. Energy Information Administration (EIA) dramatically raised its estimate of available natural gas.
