The population of the “Centennial State,” Colorado is approximately 5.92 million people. Colorado is the 21st most populated state in the United States.
In 2021, Colorado’s economy was ranked 16th in the United States in gross domestic product (GDP). The state’s economy is dependent on the aerospace, bioscience, defense, mining, oil, natural gas, agriculture, and tourism industries.
In 2004, Colorado enacted a Renewable Energy Standard, requiring investor owned utilities to sell 30% of the electricity from renewable energy sources by 2030.
In 2021, Colorado Governor Jared Polis released the Greenhouse Gas Pollution Reduction Roadmap, which details how the state will reduce emissions by 26% of 2005 levels by 2025, and 50% by 2030.
In June 2022, utilities used renewable energy (37.7 %), coal (36.5 %), and natural gas (25.8 %), to generate electricity in Colorado. Wind, solar, hydropower, and biomass are the types of renewable energy used to generate electricity in Colorado.
In June 2022, the average cost of residential electricity in Colorado was 14.42 ¢ per kWh, compared to the national average of 15.42 ¢ per kWh.
Recent renewable energy developments in Colorado include:
- 500 MW Wind Project – In September 2020, Xcel commissioned the Cheyenne Ridge wind farm at a site approximately 150 miles southeast of the state’s capital, Denver.
- 293 MW Solar Project – In October 2021, British energy company, Lightsource BP commissioned the Bighorn Solar Project at a site approximately 115 miles south of Denver.
- 200 MW Wind Project – In November 2021, American utility, NextEra Energy commissioned the Niyol Wind Project at a site approximately 125 miles northeast of Denver.
- 200 MW Solar Project – South Korean multinational company, 174 Power Global is continuing work on the Turkey Creek Solar project at a site approximately 155 miles southeast of Denver. The project is scheduled to be commissioned in 2023.
- 150 MW Wind Project – In August 2021, electric cooperative, Holy Cross Energy commissioned the Arriba Wind Farm at a site approximately 100 miles southeast of Denver.
- 140 MW Solar Project – German renewable energy company, Juwi is continuing work to build the Coyote Gulch solar project at a site approximately 250 miles southwest of Denver. The project is forecast to be commissioned in 2023.
- 123 MW Solar Project – Illinois power company, Invenergy is continuing work on the Boutique Solar project at a site approximately 250 miles southwest of Denver. The project is forecast to be commissioned in 2025.
- 110 MW Solar Project – Juwi is continuing work on the Dolores Canyon project at a site approximately 200 miles southwest of Denver. The project is forecast to be commissioned in 2023.
- 104 MW Wind Project – In May 2021, Spanish renewable energy company, EDP Renováveis commissioned the Crossing Trails Wind Farm at a site approximately 135 miles southeast of Denver.
- 80 MW Solar Project – In May 2021, Colorado renewable energy company, Guzman Energy is continuing work on the Garnet Mesa solar project at a site approximately 150 miles southwest of Denver. The project is forecast to be commissioned in 2023.
Commercial coal mining began in Colorado in 1859, near the town of Boulder. Coal was initially used to fuel steam engines for the railroad, forges, and furnaces. In 2020, seven coal mines were operating in Colorado.
In 2010, 71.9% of Colorado’s electricity was generated from coal-fueled power plants. In June 2022, 36.5 % of Colorado’s electricity was generated from coal. Why the decrease?
- Economics – The cost to generate power from wind, solar, and hydropower is significantly cheaper than coal. The cost to generate power from coal-fired plants is over twice the cost of wind or solar.
- Environment – Coal ash, the product of coal burned in a power plant contains arsenic, mercury, and lead; which are toxic. In 2019, coal ash was reported to have contaminated the ground water around 241 coal-fired plants in America.
- Climate Change – Coal generates 40% to 45% more greenhouse gases than natural gas.
In 2021, Colorado’s largest electric utility, Xcel announced it will add 2,300 MW of wind projects over the next ten years. Xcel’s goal is to cut its carbon dioxide (CO2) emissions 85% by 2030.
The move to renewable energy across America is being driven by ever increasing concerns over global warming and climate change. Compelling economics of low-cost reliable renewable energy, compared to coal have accelerated the move to wind and solar by most utilities.
The Centennial State is giving coal, the cold shoulder and turning to clean, green. Reliable, low cost renewable energy.
