The 7 Most Energy-Efficient States

July 23, 2014

Massachusetts overtook California this year as the top state for energy efficiency, according to the American Council for an Energy-Efficient Economy’s state scorecard. California had been the leader for the past four years, but Massachusetts’ “Green Communities Act,” which has powered up investments in energy efficiency throughout the state since 2008, helped push the state to the No. 1 spot this year.

“The legislation requires electric utilities in Massachusetts to purchase all available energy-efficiency improvements that cost less than it does to generate power,” Thomas Bourgeois, the co-director of the U.S. Department of Energy Northeast Clean Energy Application Center, told Forbes. “It has been a major boon to energy efficiency in Massachusetts over the past three years.”

Here’s how the states stacked up for energy efficiency, according to ACEEE’s scorecard:

1. Massachusetts
2. California
3. New York
4. Oregon
5. (tie) Vermont
5. (tie) Washington
5. (tie) Rhode Island
