Solar made up 72.6% of all new electrical generation in 2025. Combined with wind, renewables made up 88.4% of all new generation in the US in 2025. I would not be surprised to see 2026 exceed those numbers.
Federal data reveals that despite changing government stances on clean energy, solar energy is not just growing in the U.S. — it is dominating new power additions.
According to released figures from the Federal Energy Regulatory Commission, first reported by Electrek, solar led all new generating capacity additions for the 28th straight month, extending a streak that now runs from September 2023 through December 2025.
Based on the FERC numbers, reviewed by the SUN DAY Campaign, utility-scale solar made up 72.6% of all new U.S. electrical generating capacity added in 2025. Wind supplied another 15.7%, meaning renewables accounted for 88.4% of new capacity last year.
December was even more revealing. As Electrek reported, citing FERC data, 17 new solar units with a combined 993 megawatts entered service that month, making up 83.2% of new generating capacity additions.
