Clean-tech in 50 states, 50 largest US metro areas

Clean Edge

Clean Edge’s “2015 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. across a range of categories including electric vehicle (EV), clean electricity, green building, patent, venture and policy activity.

This year’s Leadership Index shows some surprising movement within the top 10. Hawaii, Vermont and Connecticut’s continued rise in the rankings illustrate these states’ strengthened commitment to a cleaner, more efficient economy. And for the first time, Chicago made the top 10 of the Metro Index, joining a diverse group of cities from across the U.S.

The “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 EVs and renewables adoption to patent 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.

Key report findings:

  • Last year, utility-scale wind (27 percent) and solar power (20 percent) combined for 47 percent of new U.S. generation capacity. Based on this expansion, 11 states now generate more than 10 percent of their electricity from nonhydro renewable energy sources, with three of these states — Iowa, South Dakota and Kansas — exceeding 20 percent.
  • When including hydropower and biomass, four states — Idaho, Washington, Oregon and South Dakota — exceed 70 percent renewables generation.
  • Last year, California became the first state in the nation to garner 5 percent of its electricity from utility-scale solar.
