What is the IRA?

I just finished listening to a podcast from The Carbon Copy, titled “The make or break moment for America’s energy transition.” In the episode, the host, Stephan Lacey talks with two individuals who were both highly involved in the conversation and development of the Inflation Reduction Act (IRA), Jigar Shah, the director of Loan Program Office at the U.S. Department of Energy, and Katherine Hamilton, the Chair of 38 North Solutions. Shah explains the IRA as the “how” for the climate movement. For years, environmentalists have known about climate change and what is needed to avoid the most permanent and damaging consequences. The question has been: how do we make the necessary changes?
