ENERGY STAR is a joint program of the U.S. Environmental Protection Agency and the U.S. Department of Energy helping us all save money and protect the environment through energy efficient products and practices. In the residential sector, the ENERGY STAR label identifies products and new homes which meet guidelines for energy efficiency, and offers guidelines to improve the efficiency of existing homes. In the commercial sector, EPA's ENERGY STAR partnership offers a proven energy management strategy that helps in measuring current energy performance, setting goals, tracking savings, and rewarding improvements. Results are already adding up. Americans, with the help of ENERGY STAR, saved enough energy in 2005 alone to avoid greenhouse gas emissions equivalent to those from 23 million cars -all while saving $12 billion on their utility bills.
