Renewable Energy Standard

In 2004, Colorado passed the first voter-led Renewable Energy Standard (RES) in the nation, requiring electricity providers to obtain a minimum percentage of their power from renewable energy sources. The legislature has increased the amount of renewable energy required three times since 2004, including HB10-1001 which required investor-owned utilities to generate 30% of their electricity from renewable energy by 2020, of which 3% must come from distributed energy resources. The most recent update, SB 13-252, requires cooperative utilities to generate 20% of their electricity from renewables. The RES has sparked the development of hundreds of new renewable energy projects across the state, generating thousands of jobs and helping to reduce the state's greenhouse gas emissions.
