City of Aspen: For years, Aspen, Colorado has been known for the cultural events, food, music and more that call the city home. Now, add renewable energy to that list.
In 2015, Aspen made a complete transition to 100-percent renewable electricity. The city of over 6,600 accomplished this feat through a combination of a bond-funded hydropower project, power purchase agreements for wind and hydropower, and smaller amounts of energy from solar and landfill gas. Aspen officials reported that they’ve already seen the benefits in the form of “reductions in [greenhouse gas] emissions, low and stable electricity rates for our customers, and setting an example for other communities to follow suit and do right by the environment.”
