Energy generation by state 2025 report

Electricity comes from a variety of sources, including nuclear, wind, and solar. Other major power sources include coal in most states and hydroelectricity in others. The sources vary by state, so the power generated in your state could be very different from another state.

Choose Energy’s June 2025 Electricity Generation Report analyzes the latest data from the U.S. Energy Information Administration (EIA) to show how electricity is produced by state. This report details the energy mix for each state using the most recent EIA figures, which reflect electricity production in March.

Texas produces the most electricity in the U.S. The Lone Star States accounted for 12.94% of the nation’s total energy production in March.

The following table shows a state-by-state breakdown of energy production from major power sources, measured in thousand megawatt-hours.

(This table does not include energy generation from petroleum, geothermal, biomass, or other power sources because they make up a minimal percentage of the mix in most states. However, there are some exceptions. Petroleum, for example, accounts for almost 70% of Hawaii’s energy production, but only a tiny amount in most other states.)

Coal has long been considered the “dirtiest” fuel for electricity production, although generators have made great strides in recent years to lessen the environmental impact. In March, 14.72% of U.S. electricity came from coal.

Natural gas burns cleaner than coal, but many environmentalists warn that it produces methane. Natural gas accounted for 35.62% of electricity produced in the U.S. in March.

Is nuclear power clean or dirty? It depends on your perspective. It produces a far smaller carbon footprint than coal, oil, or natural gas, so in that respect, it’s clean. But there’s the problem of what to do with the spent fuel, and it’s difficult to overlook that issue. Nuclear energy made up 18.71% of all electricity in the U.S. in March.

States along Tornado Alley lead the way in wind energy generation. In March, wind power accounted for 15.18 % of U.S. electricity.

Nationally, solar energy made up 9.33% of all electricity generated in March. California produced the highest percentage of its electricity from solar this month.

Hydroelectric power is one of the cleanest energy producers. It accounted for 6.6% of the national energy mix in March. Washington depends heavily on hydroelectricity, which is one of the reasons the state consistently has one of the lowest average electricity rates by state.
