City of Aspen - Renewable Energy Goal

May 26, 2021


Note: As of September 2015, Aspen obtains 100% of its electricity from renewable sources (46% hydroelectric, 53% wind, 1% landfill gas).

In 2005, the City of Aspen set a renewable portfolio goal that has since been increased to 100% renewable energy by 2015. In 2013, 75% of Aspen’s electricity was generated using renewable resources, predominantly hydro and wind.

Approximately 27% of the electricity used by the City of Aspen comes from wind turbines located in Kimball, Nebraska. An additional 45% of the City's electricity comes from hydroelectric plants.
