In the past twelve months, spanning from September 2024 to August 2025, Colorado's electricity consumption relied heavily on fossil fuel sources, which accounted for more than half of the state's power generation. Specifically, fossil fuels such as coal and gas comprised approximately 26% each of the electricity mix. Meanwhile, low-carbon energy sources contributed a significant portion—almost 42%—to the state's electricity. Wind was the most considerable contributor within this category, supplying over a quarter of the electricity, while solar (both utility and behind-the-meter) contributed over 11% together. Hydropower made up a smaller fraction with about 3%. Notably, net imports provided close to 6% of the total electricity supply, reflecting a modest dependency on external sources.

Is Electricity Growing in Colorado?
Electricity consumption in Colorado, interestingly, appears to have decreased in recent times. The average electricity usage is currently about 10,674 kWh per person, which is nearly 1,050 kWh less than the record consumption noted in 2006. This decline is concerning as we move towards a future requiring increased energy demand due to rapid electrification and technological advancements. On a more positive note, the growth in low-carbon electricity generation is notable, reaching a record 4,455 kWh per person. Although this is only a slight increase of 25 kWh per person from the previous high in 2024, it signifies progress in sustainable energy adoption.
Suggestions
To enhance its low-carbon electricity generation, Colorado should expand its existing capacities in both wind and solar power, given their substantial contributions thus far. Observing regions like Iowa and South Dakota, where wind contributes to more than half of their electricity generation, could offer valuable insights for expansion. Additionally, exploring the potential for nuclear energy could be transformative for Colorado. States like Illinois and New Hampshire have successfully integrated significant portions of nuclear power into their electricity mix. By learning from these regions, Colorado could build a more diverse and sustainable energy portfolio through strategic investments in solar and nuclear energy.
History
Historically, Colorado has seen a dynamic shift in its low-carbon electricity generation. In the mid-2000s, particularly towards the end of that decade, wind energy experienced substantial growth, marked by notable increases in generation in several years, such as 2005, 2008, and 2011. The hydropower sector experienced some fluctuations, with incremental gains and losses around the early 2010s. More recently, from 2016 onward, wind power has continued to expand, with significant increases observed in 2020, 2021, and 2022, although there was a brief decline in 2023. This rising trend underscores a firm commitment to reducing carbon emissions, even as fossil fuels remain a dominant energy source. To further this trajectory, maintaining focus on wind and exploring additional clean sources will be crucial.
