While California leads the U.S. clean energy transformation toward decarbonization, seven Northeastern states—New York, Massachusetts, Connecticut, New Hampshire, Vermont, Rhode Island and Maine—when combined, rival the Golden State in renewable energy deployment, energy efficiency (EE) and electric vehicle (EV) adoption.

The U.S. renewable energy industry is focused on Hawaii as the island state takes a pivotal position in advancing clean generation technologies, serving as a test bed of what other states might do as the nation moves rapidly toward more sustainable energy technologies.
