The Inflation Reduction Act (IRA), passed in 2022, represents the largest federal clean energy investment in history. IRA provides billions of dollars in funding through direct spending and tax credits that can be used to preserve and retrofit affordable housing, reduce energy costs, and increase community resilience. It will provide $369 billion for investments in climate resilience, energy security programs, and efficiency improvements and a total of $25 billion that is directly targeted to, or can be leveraged, for affordable housing.
