Utility-scale net generation by source, TWh; shares use total utility-scale output.
United States electricity generation is grouped by source for EIA’s 2025 utility-scale annual totals. The rows use net generation converted from thousand megawatthours to terawatthours and shares of the 4,429.5 TWh utility-scale total. Natural gas ranked first at 1,807.3 TWh and 40.8% of generation, followed by nuclear at 784.8 TWh. Natural gas and nuclear together accounted for 58.5% of utility-scale generation, while EIA marks the 2025 values as preliminary.

This frame is utility-scale net generation. EIA reports separate small-scale solar estimates; those are not included in the utility-scale denominator. The stacked graphic combines conventional hydroelectric and other small utility-scale sources into Hydro & other, while the facts retain the source-level rows.
Use EIA Electric Power Monthly Table 1.1 for major generation sources and Table 1.1.A to separate wind from other renewable sources. Convert thousand MWh to TWh by dividing by 1,000. Shares use total utility-scale net generation of 4,429,502 thousand MWh.
All generation values come from EIA Electric Power Monthly annual 2025 rows. The period is complete but preliminary according to EIA notes.
