The Sustainable Energy Resources for Consumers (SERC) grant program awarded a total of $90 million to 101 high-performing local weatherization agencies in 27 states to install in homes eligible for traditional WAP services additional renewable energy and advanced energy efficiency measures that are not typically installed through WAP. SERC demonstrated that the national weatherization network is capable of installing and delivering a wide range of new and innovative renewable energy and energy efficiency measures and services, but the usability and adoptability of some technologies may prove impractical for the WAP network and the demographics for which it serves.

Results from the evaluation are documented in a report entitled Assessment of the US Department of Energy’s Sustainable Energy Resources for Consumers Grant Program (ORNL/TM-2017/703).


We want to thank the many people who helped make these evaluations possible, including: the grantees and local weatherization agencies that completed surveys, hosted site visits of their projects, and engaged in informative discussions throughout the grant cycles; the utility companies that provided billing histories; and the weatherization recipients who participated in interviews and provided invaluable feedback.
