Energy Efficiency Resources

The Database for Energy Efficient Resources (DEER) contains information on selected energy-efficient technologies and measures. The DEER provides estimates of the energy-savings potential for these technologies in residential and nonresidential applications. The database contains information on typical measures -- those commonly installed in the marketplace -- and data on the costs and benefits of more energy-efficient measures. Energy-efficient measures provide the same energy services using less energy, but they usually cost slightly more.

Updates to the Database for Energy Efficiency Resources (DEER) have been developed by the California Public Utilities Commission (CPUC) with funding provided by California ratepayers.
