Questions and Answers about the Home Energy Saver

What is the Home Energy Saver?
Home Energy Saver is a Web site for homeowners and renters who want to reduce their energy bills. This home energy information resource employs advanced simulation software with an easy-to-use interface that tells the user how much money he or she spends on the house's energy bills, and how much he or she could save by installing energy-efficient measures and technology. Home Energy Saver is the first site of its kind on the Internet. The site also provides links to many other Web sites to help make these improvements happen, and an email link to experts at the Department of Energy who can answer home energy-related questions.

No other building energy software makes this technology available to the consumer and homeowner in such an easy-to-use package.
How do I use Home Energy Saver?
Home Energy Saver is easy to use. Start by inputting your zip code to get an energy bill breakdown for the average house in your area, and an energy-efficient house in your area.
