ENERGY STAR was introduced by EPA in 1992 as a voluntary, market-based partnership to reduce greenhouse gas emissions and other pollutants associated with energy use. Today, the ENERGY STAR label can be found on more than 60 kinds of products as well as new homes and buildings. Last year alone, Americans, with the help of ENERGY STAR, saved $18 billion on their utility bills and prevented greenhouse gas equivalent to those of 34 million cars. Products, homes and buildings that have earned the ENERGY STAR prevent emissions by meeting strict energy-efficiency specifications set by the EPA. For more information, go to energystar.gov.
