Quick Facts

  • Pennsylvania is the nation's second-largest natural gas producer after Texas, with natural gas output in the state totaling 7.5 trillion cubic feet in 2022.
  • Pennsylvania is the third-largest coal-producing state after Wyoming and West Virginia, and it is the second-largest coal exporter to foreign markets after West Virginia.
  • In 2022, Pennsylvania ranked second after Illinois in electricity generation from nuclear power. However, since 2019 natural gas has surpassed nuclear energy as the largest source of in-state electricity generation.
  • Over half of Pennsylvania households use natural gas as their primary home heating fuel, and the state's 49 underground gas storage sites--the most for any state--help meet regional heating demand in winter.
