The 14th edition of the ACEEE State Energy Efficiency Scorecard provides a progress report on state energy efficiency policies and programs that save energy while producing environmental and economic benefits. We use data vetted by state energy officials to rank states in five categories—utility programs, transportation, building energy codes, state initiatives, and appliance standards. Top finishers in this year’s Scorecard include California, Massachusetts, Vermont, Rhode Island, and New York. The most-improved state in 2020 was Nevada; other significantly improved states included New Mexico, Colorado, New Hampshire, and Virginia, as well as the District of Columbia. In addition to California and Massachusetts, regional leaders include Virginia, Minnesota, and Colorado. Others highlighted as states to watch include New Jersey, North Carolina, Michigan, Arizona, and Washington State. The State Scorecard shows that energy efficiency is a key resource in these states and others, with utilities spending approximately $8.4 billion nationwide in 2019 on efficiency programs and saving 26.9 million MWh of electricity.
