According to the Energy Information Administration (EIA), over 87% of the natural gas consumed in the US comes from domestic sources. The proportion of total U.S. natural gas production coming from shale resources has grown from less than 1% in 2000, to 20% in 2010. By the end of 2011, shale resources will produce 25% of U.S. natural gas. (MIT Study on the Future of Natural Gas ) Due primarily to technological innovation, hydraulic fracturing and horizontal drilling have made shale gas extraction from previously inaccessible domestic shale formations feasible and economical.
