Developed by the Environmental Energy Technologies Division at the Lawrence Berkeley National Laboratory, this site is designed to help homeowners save energy and money. The heart of the site is the Energy Advisor, which allows users to enter their area code to receive initial energy use estimates and then receive customized results after entering more details about their home. The Energy Advisor also offers recommendations on selected upgrades to help your home become energy efficient. Several on-site QuickTime movies demonstrate use of the Home Energy Advisor. Additional resources include the Home Energy Librarian, which offers a large number of annotated energy conservation links; a glossary of energy terminology; and the Making it Happen Module, which contains a collection of tips and links to help users capitalize on energy savings opportunities.
