Renewable Energy

In 1885, Aspen became the first American municipality west of the Mississippi to use hydroelectric power. Today, the City of Aspen electric system uses over 70% renewable energy.

Our long-term goal is to have city-owned facilities run with 100% renewable energy by 2020, and eventually extend this to all Aspen residents. By showing the economic viability of renewable energy integration, we hope this model will be adapted worldwide.

Geothermal

Using a closed-loop system of deep aquifer production and reinjection walls, the City of Aspen will develop resources to provide heat without consumptive use of water.

Hydrogen

Feasibility studies have been performed to replace communication center battery backup systems, and emergency backup power for the hospital, with hydrogen fuel cell production.

Hydroelectric

The City of Aspen energy supply is 45% hydroelectric, including the Ruedi Dam and Maroon Creek Hydroelectric facility. The Castle Creek Energy Plan will add another renewable energy model, with a hydroelectric facility, education center, and museum.

Solar

A solar thermal panel system is helping us meet our domestic hot water supply, and the water department is installing a solar voltaic system on the electric grid under the Solar Voltaic Project, reducing our community's carbon footprint by an estimated 9,215,000 lbs.

Wind

26% of the City of Aspen's total renewable energy production comes from wind power, and more wind power purchases are possible in the future.

Learn More

The U. S. Department of Energy website on Energy Efficiency and Renewable Energy offers resources to learn about energy efficiency in the industry, power, and transportation sectors and renewable energy technologies.

Learn about the technology that fuels renewable energy with the National Renewable Energy Laboratory, and initiatives available to increase renewable energy usage.

For statistics renewable energy, and analysis on resources, supply, production, consumption for all energy sources, see the Energy Information Administration from the Department of Energy.

Get Involved

Aspen Green Initiative Events take place all year long – visit the calendar to see what is happening in our community!

Renewable Energy Incentives are available through Aspen Green Initiatives to offset the cost of installing renewable energy generators on your property.

Neighborhood Meetings are a great way to learn more about the Castle Creek Energy Plan, and have your questions and concerns addressed.
