The bigger picture
Wind and solar now make about one kilowatt-hour in six, in the US and worldwide. In 2025, utility-scale wind and solar generated 17.2% of US electricity: 10.4% from wind and 6.8% from solar.1 The global share was 17.3%, more than three times the 4.5% of 2015, and renewables as a whole (33.8%) overtook coal (33.0%), which Ember notes is the first time in 100 years.2
Others are further along. Wind and solar supplied 22% of China's electricity in 2025, above the OECD average of 20%,3 and 30% of the EU's.4
What the data shows
In percentage terms, batteries are the fastest-growing part of the fleet. Almost all of the 55 GW of battery capacity operating today came online after 2020: 16 GW in 2025 alone, and another 12 GW by September 2026. Texas and California hold 36 GW of it. The median plant stores two hours of energy, and most are built for one, two or four.5
Solar has led additions since 2022, at about 30 GW a year in 2024 and 2025. Wind additions have slowed to 5 to 7 GW a year, a third to a half of the 2020 peak.5
These figures count plants that are still operating, by the year their first unit came online, so retired and repowered capacity does not appear in its original year.
How it was built
- Sources: .6 EIA data is public domain. Plants are grouped by EIA plant ID, so a project built in phases may appear as several plants.
- Capacity factor is monthly net generation divided by nameplate AC capacity and the hours in the month. It includes curtailment, outages and weather, and cannot separate them.
- New plants: the month a plant's first unit came online, and the months before it, are left blank. For plants built in phases, each month uses the capacity in service that month. Plants with fewer than six months of data show no chart.
- Batteries: EIA reports only net energy for storage, which is negative because of charging losses and does not measure performance. Storage plants show capacity and duration only.
