ASPEN, COLORADO achieved 100% renewable energy by 2015

Report (2015): “Aspen is one of three U.S. cities to run on 100 percent renewable energy as of today, according to city officials. The Colorado mountain town is best known for its posh ski resorts, but this beautiful town also has established itself as a leader in environmental stewardship… The first two U.S. cities to reach the goal were Burlington, Vermont and Greensburg, Kansas, which decided to make the move after it was devastated by a powerful tornado in 2007 ” ( Cole Mellino, “Third U.S. city goes 100% renewable”, EcoWatch, 9 September 2015: http://ecowatch.com/2015/09/03/city-goes-100-percent-renewable/ ).
