One of the arguments often raised to support shale gas (and shale oil) drilling is that it will help America become energy independent. In a wide-ranging article on the topic, Bloomberg says that promise is being fulfilled—because of hydraulic fracturing. The article starts this way:
The U.S. is the closest it has been in almost 20 years to achieving energy self-sufficiency, a goal the nation has been pursuing since the 1973 Arab oil embargo triggered a recession and led to lines at gasoline stations.
Domestic oil output is the highest in eight years. The U.S. is producing so much natural gas that, where the government warned four years ago of a critical need to boost imports, it now may approve an export terminal. Methanex Corp., the world’s biggest methanol maker, said it will dismantle a factory in Chile and reassemble it in Louisiana to take advantage of low natural gas prices. And higher mileage standards and federally mandated ethanol use, along with slow economic growth, have curbed demand.
The result: The U.S. has reversed a two-decade-long decline in energy independence, increasing the proportion of demand met from domestic sources over the last six years to an estimated 81 percent through the first 10 months of 2011, according to data compiled by Bloomberg from the U.S. Department of Energy. That would be the highest level since 1992.*
