U.S. Renewable Energy Growth Surges to New Record in 2024
America’s renewable energy sector reached historic milestones as wind, solar, and battery storage overtook coal and transformed the power generation landscape.
U.S. Renewable Energy Breaks Records in 2024
2024 marked a milestone year for renewable energy growth in the United States, as wind, solar, and battery storage achieved historic records. For the first time, wind and solar combined surpassed coal in total electricity generation, while battery systems grew at unprecedented rates, supporting the clean energy transition and grid reliability.
Across a decade of rapid change, America’s shift to renewables is reshaping the power system, sustainability strategies, and climate goals.
Key Highlights: Historic Shifts in U.S. Power Generation
- Wind and solar together generated more U.S. electricity than coal for the first time.
- Solar power grew by 27% in 2024, becoming the fastest-expanding electricity source.
- Installed solar capacity reached 220 GW, now providing over 7% of the nation’s electricity.
- Battery storage installations nearly doubled, reaching close to 29 GW and enhancing grid reliability.
- Wind power growth plateaued, but total wind capacity climbed to approximately 153 GW.
- Electricity demand rebounded, growing 3% in 2024 after years of stagnation.
Clean Electricity Transition: Solar and Wind Surpass Coal
The year 2024 saw a pivotal shift in America’s energy mix. Wind and solar combined rose to 17% of total electricity generation, overtaking coal, which dropped to an all-time low of 15%. This achievement highlights the accelerating pace of the clean electricity transition, powered by record installations and favorable policy, technological advances, and economics.
Just six years ago, coal’s share was three times greater than that of wind and solar combined. By 2024, the roles had reversed, with renewables leading the way in power generation.
Table: U.S. Electricity Generation Mix (2024)
| Source | Share of Generation (%) | Total Generation (TWh) |
|---|---|---|
| Wind & Solar (combined) | 17 | 757 |
| Coal | 15 | 653 |
| Natural Gas | ~40 | 1,787 |
| Hydro | ~7 | 298 |
| Nuclear | ~19 | 853 |
The total electricity generated by wind and solar in 2024 exceeded 756,621 GWh — enough to supply over 70 million U.S. homes. Every state saw solar generation growth; wind power expanded in 39 states.
The Solar Boom: Driving Change Nationwide
Record Installations and Rapid Expansion
Solar power set installation records with 39.6 GW added in 2024, up from 27.4 GW in 2023. This explosive growth brings the total installed solar capacity in the U.S. to about 220 GW, more than doubling its share of national electricity over the past decade.
Battery storage supported this rapid solar growth, providing critical grid flexibility, peak-shifting, and reliability.
- Solar generation grew nearly eightfold over the past decade.
- Solar capacity additions made up 81% of all new power generation in 2024.
- Solar power now generates electricity in every state, with California and Nevada leading, both surpassing a 30% solar share in their grids.
- Utility-scale solar expanded most rapidly, followed by distributed rooftop solar installations.
State Leaders and Untapped Potential
California and Nevada achieved solar grid shares of 32% and 30% respectively, driven by new installations and battery integration. Texas added more new solar and batteries than any other state, demonstrating surging investment and policy support.
Still, 28 states generated less than 5% of their electricity from solar in 2024, indicating substantial room for future growth and adoption.

Battery Storage: Unlocking Renewable Energy’s Full Potential
Battery systems play a decisive role in America’s renewable transition. In 2024, the country added a record 10 GW of utility-scale battery storage — a 47% increase in total capacity to nearly 29 GW. Batteries enable solar and wind energy to be stored and dispatched when needed, improving grid reliability and reducing dependence on fossil fuels.
States like California installed more battery storage than solar capacity, transforming the ability to use daytime solar energy during evening peak hours.
- Distributed battery storage also surged, with residential solar-plus-storage attachment rates reaching 25%.
- Batteries supported 1 GW of storage for every 3 GW of solar added nationwide.
- Texas and California led in utility-scale battery installations.
Wind Power: Growth and Challenges
While wind power remains a major contributor to U.S. electricity generation, growth slowed in 2024. Only 5.3 GW of new wind capacity was installed, bringing the total to about 153 GW.
- Challenges included supply chain disruptions, permitting delays, grid interconnection issues, and a strategic focus on upgrading older facilities.
- Despite slower growth, wind generation expanded to 42 states, with Texas, Iowa, Oklahoma, California, and Florida leading the way.
- Wind power grew 2.4-fold from 2015 to 2024, outpaced only by the dramatic expansion of solar.
Electricity Demand, Fossil Fuels, and Emissions
After more than a decade of flat electricity demand, 2024 saw a 3% increase — the fifth-largest in the 21st century. This surge was partly a rebound from a milder summer in 2023 and reflects rising electrification across industries and transportation.
- Natural gas generation also increased but at a slower rate than solar, which absorbed a greater share of rising demand and offset coal’s decline.
- Despite a modest 0.7% uptick in overall CO2 emissions due to increasing fossil fuel use, per-unit electricity emissions are at their lowest ever, thanks to renewables.
- The ongoing fall in coal generation and expansion of renewables kept carbon intensity down as total demand rose.
Regional Trends and State-Level Leadership
The transition to clean electricity varies widely by region and state:
- Texas led the country in both solar and wind installations, powering major portions of its grid with clean energy.
- California achieved record levels for both solar and battery storage, reshaping its evening grid through peak-shifting batteries.
- Illinois became the latest state where combined wind and solar overtook coal, following the leads of Arizona, Colorado, Florida, and Maryland.
- Florida also saw significant renewable expansion, particularly with utility-scale solar.
Challenges and Opportunities
Barriers to Scaling Up Wind and Solar
- Permitting, financing, and interconnection difficulties slow new wind developments.
- Supply chain issues and grid planning bottlenecks can impede renewable buildout.
- Some states still generate less than 5% of their electricity from renewables, revealing vast untapped resources.
Investment, Policy, and Market Drivers
- Federal and state policies supporting tax credits, targets, and market access have catalyzed investment.
- Private and public capital is accelerating technology deployment and modernization — renewables made up close to 90% of new grid capacity in the first nine months of 2024.
- Global competition and local leadership foster rapid innovation and local jobs.
Decade of Progress: Wind and Solar Transform the U.S. Grid
From 2015 to 2024, the U.S. more than tripled its wind and solar electricity production. Every state saw increases in renewable generation, but leading states account for much of the growth:
- Texas, California, Iowa, Oklahoma, and Florida are top states for renewable generation.
- Solar grew 7.8-fold and wind 2.4-fold since 2015.
- Renewables are now the fastest-growing segment in electricity history, globally and in the U.S.
Future Outlook for U.S. Clean Energy
The momentum behind U.S. renewables shows no signs of slowing. Battery storage capacity is projected to grow another 47% in 2025, further enhancing the nation’s clean power grid. Solar installations continue to outperform targets, and wind remains vital despite operational challenges. These shifts are driving the cleanest, most resilient power system in American history.
