Inflation Reduction Act: 2 years later

It has been two years since President Joe Biden signed the landmark inflation reduction law.

The comprehensive legislation is a central tenet of the Biden administration's plan to usher in a new era of clean energy production in the United States through a variety of federal grants, tax breaks and other incentives designed to encourage companies to invest in domestic manufacturing.

Since the law's passage, companies in 40 states have announced 334 IRA-related projects, according to environmental group E2, which tracks data on clean energy investments. The projects have a total value of at least $126 billion and are expected to create at least 109,000 new jobs.

However, as Biden's term comes to an end, the IRA's future may be uncertain. Republican nominee and former President Donald Trump has criticized large tax credits for clean energy, leading some manufacturing executives to wonder whether he would scale back the IRA's incentives.

This uncertainty comes as many of the IRA-related projects are still under construction, hoping to benefit from the law's tax incentives, and the Energy Department continues to provide loans to manufacturers for future plants.
