Massachusetts has been ranked first as the most energy-efficient state by the American Council for an Energy-Efficient Economy (ACEEE) since 2010, locking in the top ranking for the 8th consecutive year just this month!¹ The Sponsors of Mass Save^® are very proud of this accomplishment and would like you to know that the Bay State would not have continually received this #1 ranking without the commitment and interest of customers like you.

To celebrate this victory, we’ve put together a fun, spooky Halloween-themed quiz that tests your knowledge on energy-efficient technologies and Mass Save programs that have helped keep the state’s top-notch ranking. You can find clues to the answers hidden in our previous blog posts and across MassSave.com.
