Energy Star is a program that evaluates the energy efficiency of appliances, house fixtures and other home utilities. Co-sponsored by the U.S. Environmental Protection Agency and the U.S. Department of Energy, the Energy Star program seeks to reduce greenhouse gas emissions by identifying energy efficient appliances, helping Americans save money on utility bills with more energy efficient homes.

Energy Star ratings can be applied to a variety of household appliances, fixtures, and materials, including refrigerators, washers, dryers, lighting fixtures, computers, home electronics, windows, and heating insulation. When replacing an appliance or fixture in your home, look for the Energy Star label on products that are energy efficient and help protect the environment. When building a new home, you can also hire certified contractors who agree to actively build Energy Star-rated homes.
