Renewable energy sources increased US electrical generation by more than 11% in the first quarter of 2026.

They accounted for more than 28.6% of total output, according to new data reviewed by the SUN DAY Campaign.

The SUN DAY Campaign said utility-scale solar generation rose by 23.9% during the period, while hydropower increased by 21.9%, small-scale solar by 11.9% and wind by 2.1%.

The group added that utility-scale battery energy storage capacity increased by 8.5% while coal generation fell by 11.4%.

Wind and solar, including small-scale solar, provided 20.3% of domestic electrical production in the first quarter.

The combination of wind and solar out-produced nuclear power by 14.3% and coal by 31.1%.

The US Energy Information Administration projects utility-scale renewable energy capacity will increase by 57,080.6MW between April 2026 and March 2027.

Utility-scale solar is forecast to add 42,626.1MW during the period while wind capacity is expected to grow by 14,157.4MW, including 4,155MW of offshore wind.

The EIA also projects a net decline of 4,266.2MW in fossil fuel capacity and no new nuclear generating capacity during the same period.

Battery storage capacity is forecast to increase by 23,523.8MW by April 2027, bringing total installed capacity to 69,971.1MW.

The SUN DAY Campaign said combined utility-scale renewable energy and battery storage additions could total 80,604.4MW by early spring 2027.

“The Trump Administration has now passed the one-third mark and largely failed to stop the clean energy transition,” said Ken Bossong, executive director of the SUN DAY Campaign.

“By a wide margin, renewables and battery storage will continue to dominate new growth in electrical capacity and generation.”
