  The Energy Star designation was initiated in 1992 in an effort to promote a reduction in greenhouse emissions in the United States. A voluntary labeling system that identifies energy-efficient products, the Energy Star can be applied to appliances, heating and cooling systems, and a variety of other consumer products that meet strict guidelines. Energy Star appliances use 20 to 30 percent less power than required by federal guidelines.
