Over the last two decades, natural gas has replaced coal as Pennsylvania’s main source of energy, according to a report recently released by the U.S. Energy Information Administration.

Natural gas has grown from producing just 2% of the state’s electricity in 2001 to producing 52% in 2021. Meanwhile, coal-fired power production has fallen from a 57% of the electricity generation share to 12% in 2021.

During the same time period, natural gas production has grown from 0.1 trillion cubic feet to 7.6 trillion cubic feet. Pennsylvania is second only to Texas in natural gas production. Simultaneously, coal production fell from 74.1 million tons in 2001 to 42.5 million tons in 2021, declining by 40%.
