Wind energy accounted for 16% of new U.S. generating capacity in the first half of 2025, adding 3.1 GW, according to Federal Energy Regulatory Commission (FERC) data reviewed by the Sun Day Campaign. This was nearly double the contribution from natural gas.
Key projects brought online in June included the 144 MW Crossover Wind Project in Arkansas and the 59 MW Moscow Wind Power Project in Maine. Overall, wind has expanded by 10.5 GW since late 2023, second only to solar in terms of growth.
Wind now represents 11.8% of total U.S. utility-scale generating capacity, almost equal to solar at 11.3%. Together, wind and solar make up nearly one-quarter of capacity. Including hydropower, biomass and geothermal, renewables overall now provide 32.2% of U.S. utility-scale generating capacity.
FERC’s latest three-year outlook projects 23 GW of new wind additions by mid-2028, the second-highest growth of any source after solar. By then, wind is expected to supply about 12.6% of national generating capacity, surpassing coal and approaching parity with hydropower and nuclear. At current growth rates, all renewables combined are forecast to overtake natural gas as the largest source of U.S. generating capacity by 2029 or sooner.
