More hidden costs of fossil-fuel systems - the water costs

The Drought of 2012 Teaches Us About the Value of Water: "The undisputed champion of the current U.S. energy debate is hydraulic fracturing or fracking. As conventional oil and gas resources become more difficult to come by, energy companies now have to dig deeper than ever to unearth the rich deposits of fossil fuels still available. In order to fracture shale formations that often exist thousands of feet below the surface, drillers use anywhere from 1 to 8 million gallons of water per frack. A well may be fracked up to 18 times. The water, usually drawn from natural resources such as lakes and rivers, is unrecoverable once it’s blasted into the earth, and out of the water cycle for good."
