FERC: Renewables made up 88% of new US power generating capacity to Sept 2025

Puerto Rico solar storage

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%.

IEA: Renewables and AI are rapidly transforming the world’s energy future

IEA renewables

The International Energy Agency (IEA) says renewables and AI are reshaping the world’s energy future, and that transformation is happening faster than anyone expected. In its new “World Energy Outlook 2025,” the IEA warns that energy security risks now stretch far beyond oil and gas. Critical minerals essential to clean tech, defense, and AI have become the new fault lines in global supply chains. The IEA also states that energy has become a central focus of geopolitical power struggles, making it one of the defining economic and security challenges of our time.

Solar and wind are booming in 2025, but global targets lag behind

solar 2025

The world is barreling toward another record-breaking year of solar and wind deployment in 2025, says a new analysis from energy think tank Ember. If current trends continue, we could actually triple global renewable capacity by 2030 – but only if governments catch up to what’s already happening on the ground.

FERC: For two years straight, solar leads new US power capacity

FERC solar

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%.
