U.S. Energy Information Administration
The U.S. Energy Information Administration (EIA) is the statistics arm of the federal Department of Energy. It was created in response to the 1970s energy crisis. Its staff compiles data and writes reports about the nation’s energy sectors.
In 2013, the EIA launched a monthly drilling productivity report, in response to the growth in shale oil and gas production around the nation. It focuses on six regions of the country, including Pennsylvania’s Marcellus Shale.
According to the EIA, Pennsylvania ranks second in the nation for overall energy production.
