At the state level, the U.S. Climate Alliance leads the charge. Sixteen states, including Minnesota, Colorado, North Carolina and California, represent 40 percent of U.S. GDP — they have created 13 million clean energy jobs. The Climate Alliance is a testament to the proposition that climate and energy leadership promotes good jobs and economic growth. Julie Cerqueira, executive director of the U.S. Climate Alliance, said “Iowa’s long history of leadership in clean energy, in particular the successful deployment of wind power at scale, makes its membership in the U.S. Climate Alliance both logical and valuable." Iowa should join!
