Colorado’s Road to Renewable Energy and How It Compares Across the U.S.

The state of Colorado has made substantial strides in renewable energy in recent years. Understanding its progress, including how it stacks up against other U.S. states, offers valuable insight into the broader clean energy transition.

Colorado’s renewable energy profile

According to the U.S. Energy Information Administration (EIA), in 2024 renewable energy sources accounted for 43% of Colorado’s in-state electricity net generation, a record high. Their data shows us that wind power dominates at 67% of the renewable generation in Colorado in 2024. Meanwhile, coal’s share has dropped steeply: coal-fired plants generated about 27% in 2024, down from roughly 60% a decade earlier.

By mid-2025, Colorado had about 8,455 MW of renewable energy generation capacity—about 2.2% of the U.S. total. Colorado is home to abundant wind resources (especially along the plains and mountain ridges) and substantial solar resources in the southern parts of the state. It also has policy mechanisms such as a Renewable Portfolio Standard (RPS) that requires 30% of electricity sold by investor-owned utilities to come from renewables (with a portion from distributed generation) and supportive incentives for small-scale solar and geothermal.

In summary, Colorado is tapping into its wind and solar potential, reducing reliance on coal, and moving toward a cleaner grid.

How Colorado compares with other states

Putting Colorado in a national context shows both its strengths and areas for continued growth.

Share of electricity generation from renewables:

Colorado’s 43% renewable energy share in 2024 places it among the higher-performing states. For instance, a research brief by Environment America Research & Policy Center listed Colorado as the 10th highest among U.S. states based on wind, solar and geothermal energy produced as a percentage of retail electricity sales, right behind Maine and Nevada.

Renewable consumption vs. production:

According to the U.S. Energy Information Administration, Colorado’s renewable energy made up 8.4% of the state’s total energy consumption in 2023. While renewables account for a significant share of Colorado’s electricity production, they still represent a relatively small share of overall energy consumption across all sources. See the below graph for a breakdown of total energy consumption by energy source in 2023.

National leaders:

States like Iowa, Kansas, and North Dakota (generally in the heartland) often lead in the percentage of generation coming from renewables, especially wind. For example, Reuters noted that Iowa and New Mexico had more than 50% of utility-scale generation capacity from renewables. Meanwhile, states like Texas and California lead in total volume of renewable energy produced, given their large populations, geography, and resource base although the share may be different.

Colorado’s mix vs others:

In Colorado, the renewable mix is heavily wind and solar, with wind accounting for roughly two-thirds of renewables in 2024. In contrast, some states with heavy hydroelectric capacity (like Washington) have a different profile, while solar-rich states (like Arizona and Nevada) lean more on photovoltaics.

Trend and momentum:

Colorado’s shift from coal (60% a decade ago) to renewables (43% in 2024) is notable. That pace of change positions Colorado as a mid-to-front-runner among states actively decarbonizing their electricity sectors.

Why this matters & what to watch

The transition to renewables carries multiple implications:

• Grid diversification and resilience: Colorado reducing coal and adding wind/solar helps the grid adapt to future demands, climate impacts, and regulatory pressures.
• Economic and policy drivers: Wind and solar installation bring jobs, investment, and economic activity, and state-level policy (RPS, net-metering, incentives) can accelerate that. Colorado’s early RPS and incentives have helped.
• Decarbonization and climate goals: With 43% renewables in electricity generation, Colorado is better positioned to meet greenhouse-gas reduction targets, particularly in electricity.
• Growth opportunity: Even with strong progress, Colorado still has room to grow, especially in non-electricity sectors (where renewables consumption is only about 8.4% of total energy use) and in increasing the scale of solar, storage, and other emerging renewables (geothermal, biomass).
• Interstate leadership: States with large resource bases or aggressive policy frameworks often set benchmarks. Colorado’s performance shows that states of large size, diverse geography, and mid-range population density can make meaningful progress, but competition from leading states remains.

Overall, Colorado is thriving in the renewable energy space, considering electricity generation from renewable energy sources have nearly tripled in the past decade. Wind has played a dominant role, and coal has declined sharply. Compared to the rest of the U.S., Colorado is among the stronger performers in various categories. There remains opportunity for further growth particularly by further raising the renewable share in overall energy consumption (beyond electricity), expanding solar and storage, and pushing grid flexibility.
