Why is energy efficiency important?

Energy efficiency means using less energy to accomplish the same task. By improving your energy efficiency, you reduce the size (and cost) of the renewable energy system needed to power your home. Improving your energy efficiency is the first and most important step toward adopting renewable energy.

The more efficient use of energy throughout our country results in less money spent on energy by homeowners, schools, government agencies, businesses, and industries. The money that would have been spent on energy can instead be spent on consumer goods, education, services, and products. For more information, see the American Council for an Energy-Efficient Economy and the Alliance to Save Energy Web sites.

An energy-efficient economy can grow without using more energy. In 1998, for instance, the U.S. gross domestic product increased 3.9%, while U.S. energy use decreased by 0.3%.
