Pennsylvania coal comeback: Trump policies and AI data center demand revive coal-fired power plants

An op-ed in the Observer-Reporter argues that Pennsylvania coal is making a comeback after years of decline. The author traces the history of bituminous and anthracite coal mining in the state and notes that coal remains the dirtiest fossil fuel, responsible for roughly 40% of global emissions from fossil fuel use. Federal regulations and cheaper natural gas had pushed coal toward retirement, but recent policy changes under the Trump administration and surging energy demand from AI and cloud data centers are keeping coal plants online. The article highlights that since 2025, executive orders have prevented coal plant shutdowns, designated coal as a critical mineral, and provided federal subsidies. Meanwhile, data center load growth is overwhelming regional grids, forcing utilities to delay retirements. The piece does not address whether carbon capture retrofits are feasible or how this affects state-level clean energy targets in Pennsylvania. For readers tracking U.S. coal plant retirements, this op-ed provides a local perspective on how policy and demand shifts are extending coal's lifespan. The tension between reliability needs and decarbonization goals is the central thread, making it relevant for anyone watching grid emissions trends in PJM territory.
