New solar and wind capacity additions in November were the second highest in 2025 and accounted for 93% of that month’s total. Solar continues to dominate new capacity additions and has held the lead among all energy sources for 27 consecutive months, according to data released by the Federal Energy Regulatory Commission (FERC) and reviewed by the SUN DAY Campaign.

Solar continues to dominate new capacity additions and has held the lead among all energy sources for 26 consecutive months. As a result, installed utility-scale solar capacity now exceeds wind capacity for the first time, according to data released by the Federal Energy Regulatory Commission (FERC) and reviewed by the SUN DAY Campaign.

Newly published data from the Federal Energy Regulatory Commission (FERC), reviewed by the SUN DAY Campaign, reveal that solar accounted for over 75% of US electrical generating capacity added in the first nine months of 2025. In September alone, solar provided 98% of new capacity, marking 25 consecutive months in which solar has led among all energy sources.
Year-to-date (YTD), solar and wind have each added more new capacity than natural gas has. The mix of all renewables remains on track to exceed 40% of installed capacity within three years; solar alone may be 20%.

Solar and wind together accounted for 88% of new US electrical generating capacity added in the first eight months of 2025, according to data just released by the Federal Energy Regulatory Commission (FERC) which was reviewed by the SUN DAY Campaign. In August, solar energy alone provided two-thirds of the new capacity, marking two consecutive years in which solar has led every month among all energy sources. Solar and wind each added more new capacity than natural gas did. Within three years, the share of all renewables in installed capacity may exceed 40%.
