What the national mix shows

Natural gas supplied 40.8% of electricity generation in the United States since June 2025, the largest source by far. Nuclear power provided 17.7%, while coal accounted for 15.8%. Together, renewable sources generated 24.9% of the nation's electricity, with wind at 10.6%, solar at 7.2% utility-scale alone or 9.1% when rooftop solar is included, and hydroelectric generation at 5.8%. Carbon-free sources, combining renewables with nuclear, made up 42.6% of the total.

The composition of American electricity generation has shifted significantly since 2016. Coal fell sharply, declining 13.8 percentage points to 16.6% in 2025, while natural gas rose 7 points to 40.8% in 2025. Wind generation more than doubled, climbing 4.9 percentage points to 10.5% in 2025, and solar surged 5.8 percentage points to 6.7% in 2025. Overall renewables grew 9.2 percentage points from 14.9% in 2016 to 24.1% in 2025. Nuclear power edged down 2.1 percentage points, and hydroelectric generation declined 1 percentage point over the decade.

The United States generated 4,466.9 terawatt-hours of electricity since June 2025. Fossil fuels powered 57.4% of that generation, while carbon-free sources accounted for 42.6%.

Renewable = wind, solar, hydro, geothermal and biomass. Carbon-free adds nuclear. Shares are of each state’s own net generation.

Frequently asked questions

24.9% of electricity generated in the United States comes from renewables — wind, solar, hydro, geothermal and biomass — over the 12 months to May 2026. Including nuclear, 42.6% is carbon-free, and 57.4% comes from fossil fuels.
What is the largest source of electricity in the United States?
Natural gas, at 40.8% of generation. Nuclear follows at 17.7% and coal at 15.8%, with wind 10.6%, solar 7.2% and hydro 5.8%.
Which state has the highest share of renewable electricity?
Vermont, where renewables are 98.5% of generation, led by hydro. South Dakota follows at 81.7%. The national figure is 24.9%.
Which state burns the most coal for electricity?
By share of its own generation, West Virginia at 86.8%, followed by Kentucky at 64.3%. Nationally coal is 15.8% of generation.

How this is measured

Net generation reported to the U.S. Energy Information Administration for all sectors, averaged over the 12 months to May 2026 rather than taken from a single month — generation is strongly seasonal, and one month would say more about the weather than about the grid.

Shares are of generation, not consumption. Electricity crosses state lines, so a state can generate far more than it uses, or import much of what it consumes. Utility-scale solar is what the solar share counts; rooftop panels are reported separately by EIA and are broken out on each state’s own page.
