A bipartisan group of mayors from across the country unanimously backed an ambitious commitment for U.S. cities to run entirely on renewable sources such as wind and solar in two decades. In Washington, Republicans and Democrats remain deeply divided over how to deal with climate change. But cities and states are slowly shaping policies to fight floods and add renewable sources of energy. More than 25 U.S. cities such as San Diego and Salt Lake City have already adopted the clean-energy policy, and six smaller cities including Aspen, Colorado, and Burlington, Vermont, have reached goals of generating 100 percent of the energy through renewable sources. Traditional energy sources still dominate, with many cities saying they need their states to pass legislation to smooth the transition.
