What the national mix shows
Natural gas supplies the largest share of electricity generated in the United States, accounting for 40.8% of the total since June 2025. Nuclear power is the second-largest source at 17.7%, followed by coal at 15.8%. Together, these three account for most of the nation's generation, with the remainder split among renewable and other sources.
Renewable generation reaches 24.9% of the total, while carbon-free sources—renewables plus nuclear—account for 42.6%. Within the renewable share, wind contributes 10.6%, solar 7.2% on a utility-scale basis or 9.1% when rooftop solar is included, hydro 5.8%, and other renewable and alternative sources make up the rest.
Since 2001, the electricity mix has shifted dramatically. Coal has fallen from 51% in 2001 to 16.6% in 2025, a decline of 34.4 percentage points. Natural gas has grown from 17.1% to 40.8%, and wind has expanded from nearly nothing—0.2% in 2001—to 10.5% in 2025. Solar, absent from the grid in 2001, reached 6.7% in 2025. Renewable generation overall has grown from 7.7% in 2001 to 24.1% in 2025. Nuclear has edged down slightly from 20.6%, while hydroelectric output has remained stable at around 5.8%.

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

How this is measured
Net generation reported to the U.S. Energy Information Administration for all sectors, averaged over the 12 months to June 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.
