Clean energy in the U.S. had a record-breaking year in 2024
• The U.S. added 47% more clean energy capacity in 2024 than in 2023
• 95% of capacity added in 2024 was carbon-free; solar and batteries made up 83% of new capacity
• Annual solar capacity additions rose by 65% in 2024
Solar grew fastest in Republican states in the South
• More than 25% of all solar was built in Texas; 35% of all planned future solar projects are in Texas
• Solar finally started growing in Republican states in the South like Arkansas, Missouri, and Louisiana
• Florida overtook California to become the second largest solar market (by annual capacity additions)
The U.S. added a record amount of new battery storage capacity
• California built the most storage capacity, followed closely by Texas
• New markets emerged in Arizona and Nevada with the addition of multiple megaprojects
• 70% of storage capacity was built in the top 4 states (CA, TX, AZ, NV)
Clean energy installations in the U.S. reached a record high last year, with the country adding 47% more capacity than in 2023, according to new research by energy data firm Cleanview.
Boosted by tax credits under the Inflation Reduction Act and the plummeting costs of renewable technologies, developers added 48.2 gigawatts of utility-scale solar, wind, and battery storage capacity in 2024. In total, carbon-free sources including nuclear accounted for 95% of new power capacity built in the U.S. last year; solar and batteries alone made up 83%.
The report finds that developers are not only building more projects but bigger ones, too. In 2024, companies built 135 solar, wind, and storage facilities with 100 megawatts or more of capacity, continuing a trend of clean energy megaprojects around the country.
Despite the growth of renewables, fossil fuels — mostly gas — still generated more than half of the U.S.’s electricity last year. Carbon-free sources including nuclear produced just over 40% of power.
This year, renewables will continue growing but at a slower pace, the report says. Based on developer projections, the U.S. could add 60 GW of large-scale clean power capacity in 2025. That would be a 26% jump from the previous year, but it’s only possible if the industry can maintain momentum despite headwinds from the Trump administration.
Solar led the way last year and is expected to do the same this year.
In 2024, the U.S. added a new record of 32.1 GW worth of utility-scale solar capacity. That’s a 65% increase from 2023, when the country added 19.5 GW of utility-scale solar. Most new solar was built in Texas, which added 8.9 GW worth of the clean energy source, followed by Florida, which built 3 GW and outpaced California for the first time. Arkansas, Missouri, and Louisiana each saw rapid growth in solar, adding hundreds of MW of capacity where relatively little existed before.
Developers expect to add 33 GW of utility-scale solar to the grid in 2025, which would represent a 3% year-on-year growth, the report finds. The U.S. Energy Information Administration, meanwhile, said in late January that it expects solar installations to decline to 26 GW this year.
Continued progress for solar — and for any clean energy deployments — will depend heavily on the Trump administration.
