What the national mix shows

Natural gas supplies 40.9% of electricity generated in the United States, the largest share in the trailing twelve months since September 2025. Nuclear power and coal together make up nearly a third of generation at 17.6% and 15.4% respectively. The carbon-free share, combining nuclear and renewables, stands at 43%, while renewables alone account for 25.4%. When rooftop solar is included alongside utility-scale solar in the calculation, the solar share rises to 9.6%; utility-scale solar alone contributes 7.6%.

The generation mix has shifted steeply since 2001. Coal's share has collapsed from 51% in 2001 to 16.6% in 2025, while natural gas has more than doubled from 17.1% to 40.8%. Renewables have grown from 7.7% in 2001 to 24.1% in 2025, driven primarily by wind power, which rose from 0.2% to 10.5%, and solar, which grew from nothing to 6.7%. Nuclear generation has remained relatively stable, declining slightly from 20.6% to 17.7%.

Across the period since 2001, generation from sources in the "other" category, which includes geothermal and biomass, has fallen from 5.4% to 2.1%. Hydroelectric generation has held nearly steady at around 5.6% to 5.8%. These shifts reflect a transition away from coal-fired generation toward natural gas and renewable energy sources, though fossil fuels still account for 57% of total generation.

How this is measured

Net generation reported to the U.S. Energy Information Administration for all sectors, averaged over the 12 months to August 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.
