Quick Facts

  • Pennsylvania's marketed natural gas production, primarily from the Marcellus Shale, reached a record 7.6 trillion cubic feet in 2021, and the state is the nation's second-largest natural gas producer after Texas.
  • Pennsylvania is the third-largest coal-producing state in the nation after Wyoming and West Virginia, and it is the second-largest coal exporter to foreign markets after West Virginia.
