As part of the ELEEP Network’s ongoing investigation of the changing energy landscape in Europe and the United States, ten ELEEP members participated in a study tour to Denver, Colorado and San Francisco, California from 19 to 24 August 2012. This trip served as a counterpoint to earlier trips to Germany/Austria in August 2011 and Germany/Denmark in March 2012, augmenting the European perspective with current information from the United States.
