Overview
- EIA preliminary data show wind and solar produced roughly 420 terawatt‑hours and about 20 percent of U.S. electricity in the first half of 2026, exceeding coal and, for the first H1 on record, nuclear generation.
- The surge was driven mainly by utility‑scale solar and large wind projects coming online, including the SunZia wind farm and the ramp of Vineyard Wind, which together lifted wind generation and pushed utility solar output up about 19 percent year over year.
- Tax credits for new wind and solar projects expired on July 4, 2026, under a prior budget law, and administration moves to tighten federal reviews and halt offshore wind have created near‑term policy headwinds that analysts say will weaken project economics after 2027.
- DOE issued emergency orders keeping several coal plants running past planned retirements to support grid reliability, a move that highlights tensions between market forces driven by low natural gas prices and political efforts to prop up fossil generation.
- The recent buildout should keep installations strong through 2027 but regional grid limits, interconnection backlogs, and the end of subsidies could slow additions later and raise power prices for consumers and developers unless new supports or cost gains emerge.
