2015 U.S. Clean Tech Leadership IndexThe U.S. Clean Tech Leadership Index tracks and ranks the clean-tech activities of all 50 states and the 50 largest metro areas in the U.S. – from EV (electric vehicles) and renewables adoption to policy and investment activity. 

The objective of the Leadership Index is to serve as a tool for regional comparative research, a source for aggregated industry data, and a jumping-off point for deep, data-driven analysis of the U.S. clean-tech market. 

To see how your state and city rank, download our summary report (53 pages; 30+ tables and charts).

Key report findings:

  • The transition to a clean-energy economy over the past seven years is remarkable, with 14 states now exceeding 10% renewable energy generation, and the top three states (Iowa, South Dakota, and Kansas) at 31%, 25%, and 24% respectively.
  • In this year's Index, California became the first state to generate 10% of its in-state electricity from utility-scale and distributed solar, with Hawaii not far behind at 7%.
  • Clean-energy deployment transcends politics. Among the Top 10 states for utility-scale clean-energy generation in our 2016 Index, half were red states during the last presidential election (Idaho, Kansas, North Dakota, Oklahoma, and South Dakota) and half were blue states (California, Colorado, Iowa, Minnesota, and Vermont).
