The U.S. Department of Energy (DOE) Weatherization Assistance Program (WAP) offers competitive grants for innovation, provides training and technical assistance (T&TA) to grantees, disseminates best practices, and scales innovation to the formula WAP. 

Innovation grants are available to WAP Grantees, Subgrantees, and non-profit organizations to demonstrate innovative technologies and approaches that go beyond the scope of the WAP formula program. These grants fund projects that support the government-wide approach to the climate crisis by driving the innovation that can lead to the deployment of energy efficiency retrofits and clean energy technologies, which are critical for climate protection.

Additionally, these grant-funded projects improve the energy efficiency of America's housing stock, and benefit low-income households by improving indoor air quality and reducing utility bills. Through place-based projects, these grants enable deeper energy retrofits of low-income housing, support the local workforce, and further accelerate The Office of State and Community Energy Program's deployment of clean energy technologies.
