The Inflation Reduction Act (IRA) and the Infrastructure Investment and Jobs Act (IIJA) are among the largest investments ever made by the federal government to accelerate the decarbonization of the U.S. economy. These Acts provide multiple incentives to spur clean energy innovation—including tax credits, subsidies, and new grant funding—to a host of different actors within the economy, from companies and universities to states and local communities. There is considerable interest and value in understanding the impact of these interventions and incentives on reducing greenhouse gas emissions, on the creation of new clean energy technologies, on the generation of jobs within the clean energy economy, and on whether and to what extent funding benefits are flowing to disadvantaged. This grant provides funding for an ongoing project by Resources for the Future (RFF) to partner with federal agencies to evaluate the impact of energy policies and programs. Grant funds will support two prongs of work by RFF. The first is establishing a hub for energy policy evaluation research by holding an open Request for Proposals to broadly source and support research projects across the academic landscape. Resources will be provided to fund between 4-8 research projects at up to $100,000,000 each to begin evaluating different elements of the IRA's impact on the energy system. Grant support will cover expenses such as faculty research time, student stipends, data access, and travel to interact with federal agencies. RFF will convene funded research teams to share progress mid-way through the project and then at the end to share results with decision makers. The second prong will be developing an evaluation system to assess the impact of specific DOE funding programs. RFF will first conduct interviews to identify what can be learned about how program evaluation operates at other relevant agencies and inventory what evaluation efforts are currently taking place at DOE. Two candidate partners include the Office of Energy Efficiency and Renewable Energy and the Office of Fossil Energy and Carbon Management.  This project is expected to result in a series of research papers, reports, policy briefs, and other publicly available outputs that will substantially advance the state of knowledge about contemporary clean energy policy and program evaluation.
