What counts as renewable here?
This guide combines reported solar, wind, hydro, geothermal, and biomass nameplate capacity. Storage is shown separately in US Grid Explorer because it shifts electricity in time rather than identifying the original energy source. The state profiles report 396,930 MW across these five renewable categories.
Largest renewable portfolios by capacity
Total megawatts highlight states with large fleets. They do not adjust for state size or total power-system capacity.
| Rank | State | Renewable capacity | Context |
|---|---|---|---|
| 1 | Texas | 65,851 MW | 36.7% of state capacity |
| 2 | California | 46,739 MW | 45.8% of state capacity |
| 3 | Washington | 25,657 MW | 81% of state capacity |
| 4 | Oklahoma | 14,094 MW | 40.9% of state capacity |
| 5 | Iowa | 13,899 MW | 56.9% of state capacity |
| 6 | Oregon | 13,759 MW | 74.6% of state capacity |
| 7 | Florida | 12,141 MW | 15.6% of state capacity |
| 8 | New York | 11,925 MW | 27.1% of state capacity |
| 9 | Illinois | 10,958 MW | 21.7% of state capacity |
| 10 | Georgia | 9,716 MW | 22.8% of state capacity |
Highest renewable shares
Portfolio share answers a different question: how much of each state's reported nameplate capacity belongs to the selected renewable categories?
Capacity is not generation
A megawatt of solar, wind, hydro, biomass, and geothermal capacity does not produce the same number of megawatt-hours each year. Weather, water, fuel availability, curtailment, maintenance, and operating economics affect output.
