The Inflation Reduction Act has sparked a manufacturing boom across the U.S., mobilizing tens of billions of dollars of investment, particularly in rural communities in need of economic development.

The future of those investments could hinge on the outcome of the U.S. presidential election. The prospect of a Republican victory has shaken the confidence of some investors who worry the IRA could be weakened or in a worst-case scenario repealed.

Companies have announced $133 billion of investments in clean energy technology and electric vehicle manufacturing since President Joe Biden signed the IRA into law in August 2022, according to data from the Massachusetts Institute of Technology and the Rhodium Group.

Actual manufacturing investment has totaled $89 billion, an increase of 305% compared to the two years prior to the IRA, according to MIT and Rhodium. Overall, the IRA has leveraged half a trillion dollars of investment across the manufacturing, energy and retail sectors, according to the data.

"It is having a transformative effect within the manufacturing sector," said Trevor Houser, a partner with the Rhodium Group. "The amount of new manufacturing activity that we're seeing right now is unprecedented in recent history, and is in large part due to new clean energy manufacturing facilities."

Some 271 manufacturing projects for clean energy tech and electric vehicles have been announced since the IRA passed, which will create more than 100,000 jobs if they are all completed, according to the advocacy group E2, a partner of the National Resources Defense Council. The investments sparked by the IRA have been a boon for rural communities in particular, Houser said.

"Unlike investment in AI and tech and finance, which is
