On April 9, the Potential Gas Committee released its estimates of the natural gas reserves in the U.S. The PGC found that the resource base is around 2,384 trillion cubic feet, up 26 percent from the 2010 estimate. The increase is tied to the shale gas boom since the estimates consider economically and technologically recoverable resources. Eastern states including New York, Pennsylvania, and West Virginia have the largest reserve with 741 trillion cubic feet.
