According to statistics from the EIA, the U.S. renewable energy adoption toward clean power contributed to 24% of the country’s overall electricity generation in 2025. This adoption has a key role across the country, supported by state action, growing wind and solar capacity, and enhanced grid investment. This blog focuses on the 20 leading U.S. states based on renewable energy and reveals how regional initiatives are setting the pace for our future clean energy landscape.
U.S. States in Renewable Energy Adoption
The table highlights the top 20 U.S. states based on renewable share of electricity generation, dominant energy sources, and key developments. Here, the tabular data is sorted based on the electricity share from renewables using the latest EIA data:
Rank
| State | Share of Electricity from Renewables | Dominant Sources
| Net Renewable Generation (GWh) | Key Developments (2024) |
1 | Iowa | 63% | Wind | ~45,000 | Wind farms generated nearly two-thirds of Iowa’s power, the highest wind share in the U.S. |
2 | South Dakota | 61% | Wind, Hydro | ~12,500 | Wind output expanded 8%, pushing renewables past 80% of total generation. |
3 | Kansas | 52% | Wind | ~22,000 | Utility-scale wind projects along the generation by ~10%. |
4 | New Mexico | 50% | Solar, Wind | ~13,000 | Rapid solar growth with the latest technology. |
5 | Oklahoma | 41% | Wind | ~21,000 | Wind output set records, remaining in the top five wind producers nationwide. |
6 | Colorado | 40% | Wind, Solar | ~15,500 | The state’s clean-energy standard spurred new solar farms. |
7 | California | 38% | Solar, Hydro, Wind | ~65,000 | Record solar output; over 50% renewable milestone achieved mid-2024. |
8 | North Dakota | 35% | Wind | ~10,000 | Added renewables reached a 40% share and multiple 200 MW+ wind facilities. |
9 | Maine | 34% | Hydro, Wind | ~5,500 | Integration of offshore wind planning and the legacy biomass fleet. |
10 | Nebraska | 33% | Wind, Hydro | ~12,000 | First-year renewables surpassed one-third of generation; the state target advanced. |
11 | Montana | 32% | Hydro, Wind | ~6,000 | Favorable hydro conditions and wind expansion sustained the majority-renewable mix. |
12 | Oregon | 31% | Hydro, Wind | ~9,500 | Hydro dominated; strong recovery in water inflows lifted renewable output. |
13 | Washington | 30% | Hydro, Wind | ~18,000 | Columbia River hydro plants kept WA among the top renewable-share states. |
14 | Idaho | 29% | Hydro, Wind | ~4,500 | Stable hydro flows and new wind capacity boosted renewables’ share to two-thirds. |
15 | Vermont | 28% | Hydro, Biomass | ~1,500 | Reached near-100% renewable generation through local biomass and legacy hydro contracts. |
16 | Georgia | 27% | Solar, Biomass | 7,500 | Maintained leadership in southeastern solar capacity. |
17 | Arizona | 26% | Solar | ~9,000 | Rapid solar growth despite drought impacts on hydro capacity. |
18 | Nevada | 25% | Solar, Geothermal | ~7,800 | Large-scale wind projects offset coal decline; transmission expansion is ongoing. |
19 | New York | 24% | Hydro, Wind, Solar | ~20,000 | Offshore wind contracts and rooftop solar pushed renewables near 30%. |
20 | Minnesota | 23% | Wind, Biomass | ~12,500 | Major solar build-out complemented long-established wind farms. |
Conclusion
The 20 leading U.S. states are based on renewable energy adoption and provide their renewable share of electricity generation, energy sources, and significant developments that are shaping the transition to a cleaner, more resilient power grid. This progress is a clear indication that the transition to renewable energy can no longer be localized to regions but now involves communities nationwide. The U.S. continues to move inevitably towards a cleaner, more resilient, and diversified energy future.
