"Supporters of the Energy Star program cite the high return on investment for taxpayers. Since it was established in the 1990s, the program has saved U.S. consumers roughly $360 billion, mostly in electricity and water costs. The program, jointly run by the Environmental Protection Agency and the Department of Energy, also saved consumers and businesses $31.5 billion in 2014 alone, while costing about $57 million a year. That puts the return on investment for taxpayers at about 550 to 1."
