Pennsylvania eclipsed neighboring West Virginia to become one of the top three energy-producing states in the U.S. in 2015, according to a federal energy agency.
The Keystone state trailed only Wyoming and Texas as a net exporter of energy in 2015, according to the U.S. Energy Information Administration, a division of the Department of Energy.
Pennsylvania’s ranking is driven primarily by the growth of production in natural gas, which soared to more than 5 trillion cubic feet in 2016, up from 573 billion in 2010.
The increase has prompted construction of numerous pipelines designed to move product to customers outside of Pennsylvania, with several lines traversing Central Pennsylvania and raising environmental concerns.
Pennsylvania also remains one of the nation’s top five coal producers.
Overall, 12 states produced more energy than they consumed in 2015. The top five were Wyoming, Texas, Pennsylvania, West Virginia and North Dakota, according to the EIA.
