US Electricity Mix by State, 2025

This page shows how 50 states and DC generate their electricity, one horizontal bar each, using EIA annual statistics for 2025. South Dakota has the highest low carbon share of any state generating at least 5 TWh, 81.2% (nuclear and renewables) of 22.2 TWh. West Virginia is the most coal dependent of those, at 86.9% coal. Rhode Island relies most on gas, 87.5%. New Hampshire has the largest nuclear share, 56.4%. Nevada has the biggest utility scale solar share, 30.3%. The largest single source is gas in 28 states, coal in 9 states, wind in 5 states and hydro in 4 states. These are EIA annual statistics for 2025; they are not real time.

Key Facts, 2025

  • 50 states and DC have an EIA generation mix for 2025.
  • South Dakota had the highest low carbon share among states generating at least 5 TWh: 81.2% of 22.2 TWh in 2025.
  • West Virginia had the highest coal share among states generating at least 5 TWh: 86.9% in 2025.
  • Rhode Island had the highest gas share among states generating at least 5 TWh: 87.5% in 2025.
  • New Hampshire had the highest nuclear share among states generating at least 5 TWh: 56.4% in 2025.
  • Nevada had the highest utility scale solar share among states generating at least 5 TWh: 30.3% in 2025.
  • In 2025, the largest single source is gas in 28 states, coal in 9 states, wind in 5 states and hydro in 4 states.
  • 2 states generate under 5 TWh a year, so their mix can be a single power station.

Small states: 2 states generate under 5 TWh a year. They are listed, but a mix that is one power station says little, so use the checkbox to hide them.

How to Read This

  • Each bar is 100% of one state's utility scale electricity generation in 2025. Each coloured segment is one fuel and its width is that fuel's share, in the same order on every bar: fossil fuels first, then nuclear and renewables. Segments of 8% or more show their percentage; every share is also in the segment's tooltip and in a hidden list for screen readers.
  • Low carbon means nuclear plus all renewables (hydro, wind, solar, bioenergy, geothermal and other renewables). Fossil means coal, gas, oil and other fossil. Click Low carbon or Fossil to sort by those totals, or any fuel in the legend to sort by that fuel's share; click again to reverse.
  • Shares are of electricity generated inside the state, not of what it consumes: power imported from or sent to other states is not in the bars. Solar here is utility scale only; EIA's state generation figures leave out small scale rooftop solar.
  • Named extremes in the text above only consider states generating at least 5 TWh. 5 states have published shares that do not add up to 100% (one category, such as "other", is negative in some states, so the positive shares can total slightly more than 100%). Those bars are rescaled to exactly 100% so they can be drawn; the percentages in the tooltips and lists are the published ones, as on each state page.

US State Electricity Mix FAQ

Which US state has the cleanest electricity mix?

Among states generating at least 5 TWh, South Dakota had the highest low carbon share in 2025: 81.2% of its electricity came from nuclear and renewable sources, according to EIA. A state generating less than 5 TWh is left out of this comparison because one plant can decide its whole mix.

Which state relies most on coal for electricity?

West Virginia had the highest coal share among states generating at least 5 TWh, 86.9% in 2025. Click Coal in the legend above the bars to rank every state by coal share.

Which state relies most on natural gas for electricity?

Rhode Island had the highest gas share among states generating at least 5 TWh, 87.5% in 2025. The largest single source is gas in 28 states, coal in 9 states, wind in 5 states and hydro in 4 states.

How do I read the state electricity mix bars?

Each bar is 100% of one state's utility scale generation in 2025. Each coloured segment is one fuel, in the same order on every bar (fossil fuels first, then nuclear and renewables), and its width is that fuel's share. Every share is also listed as text for screen readers. Small scale rooftop solar is not in EIA's state generation figures.
