Energy efficiency is a low-cost way to save money, support job growth, reduce pollution, and improve the competitiveness of our businesses. Our homes, offices, schools, hospitals, restaurants, and stores consume a lot of energy—and money. We spend more than $430 billion each year to power our homes and commercial buildings, consuming more than 70 percent of all electricity used in the United States, about 40 percent of our nation's total energy bill, and contributing to almost 40 percent of the nation's carbon dioxide emissions. And much of this energy and money is wasted—over 30 percent on average. If we cut the energy use of U.S. buildings by 20 percent, we could save approximately $80 billion annually on energy bills, reduce greenhouse gas emissions, and create jobs.
The U.S. Department of Energy leads a network of research and industry partners to develop innovative, cost-effective energy saving solutions—better products, better new homes, better ways to improve older homes, and better buildings in which we work, shop, and lead our everyday lives.
