Colorado Hits 44% Renewable Energy, Ranks 6th in Wind Power

Colorado just hit a clean energy milestone that seemed impossible a decade ago: nearly half the state's electricity now comes from the sun and wind.

New data from CoPIRG and Environment Colorado shows the state generated the equivalent of 44% of its total electricity consumption from renewable sources in 2025. That's a massive jump from just 19% in 2016, putting Colorado among America's top clean energy leaders.

The state now ranks sixth nationally for wind power and tenth for battery storage capacity. Those batteries matter because they store solar and wind energy for nighttime use and cloudy days, making renewable power reliable around the clock.

The numbers reveal a surprising pattern across the country. States with very different politics are all racing ahead on renewables. Iowa's wind farms lead the nation, while Kansas climbs the rankings fast. Colorado sits alongside Washington, Minnesota, and Oregon in the clean energy leaders' club.

Electric vehicle adoption tells a similar success story. Colorado shows substantial growth in EV registrations through 2024, with charging stations spreading across the state to match. Washington state leads the pack, but Colorado keeps pace with its mountain peers.

The Ripple Effect

Battery storage sets Colorado apart from other renewable energy leaders. While states like Kansas and Iowa generate clean power, Colorado invests heavily in the batteries that make renewables work 24/7. The state ranks tenth nationally for installed battery storage, ahead of many larger states.

Local projects show the creativity driving this transformation. Denver Botanic Gardens' Chatfield Farms now grows crops under solar panels, producing both food and clean electricity from the same land. Denver's Office of Climate Action, supported by a dedicated city sales tax, funds innovations like this across the metro area.

Clean energy advocates say Colorado should keep the momentum going by cutting red tape for homeowners installing solar panels and continuing subsidies for heat pumps, batteries, and EVs. They worry federal cuts to clean energy tax credits could slow progress just as the technology becomes more affordable.

The transformation happens faster than many expected. What seemed like an environmental dream in 2016 became everyday reality by 2025, with wind turbines and solar farms powering nearly half of Colorado's grid.
