Energy Star Program

US EPA Energy Star LogoThe Energy Star Program from U.S. Environmental Protection Agency (EPA) and the U.S. Department of Energy is designed to encourage energy efficient products and practices. The program was started in 1992 by the US EPA as a voluntary labeling program for computers and monitors. Other office equipment was added in 1995. The program was expanded in 1996, with the US Department of Energy. It now covers major appliances, office equipment, lighting, home electronics, new homes, commercial and industrial buildings.
