The recent Inflation Reduction Act (IRA), along with the Infrastructure Investment and Jobs Act (IIJA) from last year, provide more than $25 billion for programs and tax incentives to improve the energy efficiency of, electrify, and reduce greenhouse gas (GHG) emissions due to existing homes. Even larger broad GHG emission reduction programs under the IRA could be used for home energy efficiency. But the programs use a variety of mechanisms to offer varying incentives with varying criteria for overlapping measures. This brief summarizes programs that will or could provide significant resources for energy efficiency retrofits for existing single family and multifamily homes.
