U.S. Keeps Breaking Renewable Energy Records as Wind, Solar Surge Past Coal
The U.S. power grid is rapidly shifting as wind and solar surge past coal, with clean energy setting monthly and annual records; utility-scale solar and battery storage growth are driving a faster-than-ever transition across states.

- March 2025: clean sources hit 50.8% of generation; wind and solar accounted for 24.4% that month. (Ember Energy)
- Utility-scale solar surged in 2025 (12 GW in H1; 21 GW planned in H2), potentially more than half of ~64 GW new capacity this year. (EIA)
Main story
Overview: a structural shift in U.S. power
The data show a clear, sustained change: the U.S. electricity system is adding clean energy capacity faster than at any time in modern history. Wind and solar together reached 17% of electricity in 2024, overtaking coal’s 15% share on an annual basis (Ember Energy).
Key facts & monthly records
Monthly milestones are piling up. In March 2025 clean sources (renewables + nuclear + hydro) supplied 50.8% of U.S. generation, the first time fossil fuels fell below half the grid mix; wind and solar produced 24.4% that month (Ember Energy).
“Grid records are now set on compressed time scales as more wind and solar enter service and costs fall,” industry reporting notes. (Los Angeles Times)
Capacity additions: solar and storage leading the way
Utility-scale solar has surged: 12 GW installed in the first half of 2025 with 21 GW planned for the second half, meaning solar may account for more than half of the roughly 64 GW of new capacity expected in 2025 (EIA).
Battery storage growth is likewise rapid and critical: in California in 2024 battery additions exceeded new solar by about 20%, signaling a maturation of the grid’s ability to store daytime solar for evening use (Ember Energy).
Who’s leading, who’s lagging
Texas and California lead in adding solar and battery capacity—Texas for large-scale additions and California for pairing storage with solar—while adoption remains uneven: 28 states generated less than 5% of electricity from solar in 2024, highlighting regional market, siting and policy differences (Ember Energy; EIA).
Batteries and grid evolution
Battery storage is moving from supportive to essential. Pairing batteries with solar farms smooths output and provides grid services, helping utilities rely less on fossil-fueled plants during evenings and peaks. The emerging norm—projects with roughly a 1:3 battery-to-solar ratio—makes solar more dispatchable and valuable.
Monthly and weekly record-setting
Reports show grid records set nearly weekly as new projects come online. For example, renewables supplied nearly one-quarter of U.S. electricity in June 2025, up from 18% a year earlier, reflecting both buildout speed and falling technology costs (Los Angeles Times; Heartspace.ai).
Policy, investment and market drivers
Much of the momentum reflects earlier policy and incentives: roughly $100 billion in clean energy investments and incentives enacted before 2025 seeded projects and manufacturing capacity now delivering output. Market forces—low costs for wind, solar and batteries—sustain the buildout even where policy shifts occur. Private investment and corporate power purchase agreements have also accelerated project finance and deployment (Los Angeles Times; Ember Energy).
Implications for the Inland Empire, California
Economic impacts: The Inland Empire could see job growth, construction and operations roles, and local investment as developers seek large flat land and transmission access. Commercial rooftops and large employers in Riverside and San Bernardino counties may benefit from lower-cost energy and new financing options.
Grid & reliability: More battery capacity means improved evening power from local solar-plus-storage, fewer imports, and potential reductions in outage impacts. Expect permit activity, substation projects and distribution upgrades to handle two-way flows.
Environmental & social: Increased renewables can improve air quality—important in a region with historical pollution burdens—and projects can deliver community benefits like jobs, lease payments and potentially lower rates if local entities capture value.
Local policy & planning: County and city land-use and permitting choices will influence whether the Inland Empire captures development. Streamlined permitting, clear community benefits and workforce programs can help ensure equitable local gains.
What residents should expect
- Potential downward pressure on wholesale prices and greater local reliability as storage grows.
- More project proposals, public hearings and utility planning meetings—engagement early can shape outcomes.
- Opportunities for local jobs, training programs and community solar for renters and low-income households.
