EIA: 99%+ of new US capacity in 2026 will be solar, wind + storage [View all]

EIA’s latest monthly “Electric Power Monthly” report (with data through November 30, 2025), once again confirms that solar is the fastest-growing among the major sources of US electricity.

In November alone, electrical generation by utility-scale solar (>1 megawatt (MW)) expanded by 33.9% compared to November 2024, while “estimated” small-scale (eg, rooftop) solar PV increased by 11.0%. Combined, they grew by 27.5% and provided 7.2% of US electrical output during the month, up from 5.9% a year ago.

Moreover, utility-scale solar thermal and photovoltaic expanded by 34.5% while that from small-scale systems rose by 11.3% during the first 11 months of 2025 compared to the same period in 2024. The combination of utility-scale and small-scale solar increased by 28.1% and produced a bit under 9.0% (utility-scale: 6.74%; small-scale: 2.13%) of total US electrical generation for January to November, up from 7.1% a year earlier.
