Canary Media’s chart of the week translates crucial data about the clean energy transition into a visual format.

Communities around the U.S. are taking the lead to build clean energy projects designed to benefit their own residents, as we’ve been reporting this week in our series Power by the People: Clean Energy from the Grassroots. But some kinds of community-led clean-energy efforts can only succeed if the right policies are in place, and policies vary widely from state to state. So which states are most effectively supporting communities in their quest for clean energy? California and Massachusetts top the list, according to a scorecard from the Institute for Local Self-Reliance, while Kentucky and Louisiana are at the bottom.
