Why Shale Gas is Not the Solution to Our Energy Problems

http://energybulletin.net/stories/2010-12-19/will-shale-gas-turn-out-be-energy-sink

here is an excerpt from Kurt Cobb writing at the Energy Bulletin:

"Drillers are exempt from federal clean air and water regulations under a bill shepherded through Congress in 2005 by none other former Halliburton CEO Dick Cheney in his capacity as the then vice president of the United States. (Halliburton is one of the world's largest providers of drilling fluids for shale gas drilling and other oil and gas drilling operations.) That means the drillers can externalize the environmental costs of these hazardous fluids and other materials needed to fracture the shale and thereby free the natural gas. They can foist those costs on nearby residents in the form of ruined water supplies, toxic air pollution, poisoned land, and health problems for humans and animals.

"The environmental and health horrors associated with shale gas drilling are now in the news on a daily basis. But I have begun to think about the issue in another way. All of these externalized costs have an energy cost. And, the toxic fracturing fluid--millions of gallons of which are pumped into each and every shale gas well--will stretch out the time frame during which such costs are borne. No one knows what will happen to the half of that fluid which never returns to the surface during operations. There is concern that it could migrate to drinking water aquifers and destroy the drinking water not just for the few who happen to live near a drilling site, but for people living in huge swaths of the United States by polluting water sources for large cities such as New York....
