According to the most recent data from the U.S. Energy Information Administration (EIA), the mix of renewable energy sources generated more than 25% of the country’s electricity in the first three months of 2025 and nearly 33% of all electricity generated in the United States in March alone.
Comparing the first quarter of 2025 to the same time in 2024, utility-scale solar grew by 43.9%, while projected small-scale/rooftop solar PV climbed by 11.1%. Between January and March, utility-scale and small-scale solar accounted for about 6.8% of all U.S. electricity production, up more than one-third (33.7%) from 5.3% in the same period last year. This indicates that the amount of energy produced by solar power exceeded that of the country’s hydroelectric facilities (5.7%).
Furthermore, Utility-scale solar power generated 45.6% more electricity in March alone than small-scale systems, which reached 13.0%. During the month, their combined contribution to the country’s electrical production was 9.1%. This is based on the SUN DAY Campaign’s analysis of the data.
In 2025, wind also had a great start, generating 9.5% more power in the first three months than the previous year. That production more than doubled that of the country’s hydroelectric facilities and accounted for roughly one-eighth (12.2%) of all electrical generation in the United States. Wind-generated power accounted for more than one-seventh (14.8%) of the country’s electrical supply in March alone, an increase of 11.1%.
Almost one-fifth (19.0%) of the U.S. electricity production in the first quarter of 2025 came from wind plus utility-scale and small-scale solar, up from 17.0% in the first three months of 2024. Almost one-fourth (23.9%) of the electricity produced in the United States in March came from solar and wind power.
Wind and solar power generated 6.8% more energy than coal and 6.0% more than the country’s nuclear power reactors in the first three months of this year. The disparity widened dramatically in March alone, when solar + wind generated 66.5% more energy than coal and 31.0% more than nuclear.
All forms of renewable energy generated 10.5% more power in the first quarter of this year than they did in the same period last year (12.5% more in March alone), and they accounted for more than one-quarter (26.1%) of the nation’s total electricity output, up from 24.8% in the previous year. In March alone, electricity production from all renewable sources set a new high and accounted for over one-third (31.9%) of all electricity generated in the United States. Furthermore, it approached that of natural gas (34.8%), whose electrical production fell by 8.9%, for the first time.
With a rapidly narrowing gap, the mix of renewables has solidified its position as the second-largest source of electricity production, trailing only natural gas.
