U.S. power markets surged in 2025 due to higher gas prices, data center demand, and coal rebound, while renewable growth may slow post-2027 amid expected policy rollbacks.

In December 2025, U.S. power markets show rising volatility, with coal generation up 13% through September due to higher natural gas prices, increased demand from data centers and LNG exports, and grid strain. Despite wind and solar generating 646 TWh—surpassing coal’s 561 TWh—renewable growth may slow after 2027 due to expected policy rollbacks, including the elimination of clean energy tax credits under a second Trump administration. Solar added 2 GW in September alone, accounting for 75% of new capacity in 2025, while natural gas prices are projected to reach $4/MMBtu in 2026. Meanwhile, top renewable energy stocks to watch include Quanta Services, WEC Energy Group, NOV Inc., Clearway Energy, HA Sustainable Infrastructure Capital, NWTN Inc., and Nuvve Holding Corp., driven by strong trading volume and exposure to clean energy infrastructure, electric vehicles, and grid modernization.
