The momentum in U.S. clean tech manufacturing investment has slowed sharply in recent quarters. A new study by the Rhodium Group and MIT reveals that in Q2, companies canceled $5 billion worth of clean tech projects, compared to only $4 billion in new investments announced. Actual manufacturing investments dropped by 15%, highlighting a troubling trend for the sector.
The pullback follows the GOP’s reconciliation bill, which scaled back major provisions of the Inflation Reduction Act (IRA)—a law that previously fueled historic growth in clean energy and manufacturing. With weakened demand for electric vehicles and the removal of key production tax credits, industries like EV and battery manufacturing have been hit the hardest.
Cancellations in Q1 focused on EV production, while Q2 saw significant cutbacks in battery factory projects. Still, battery production remains central to the industry, with $8 billion in new investments recorded in Q2 despite the wave of cancellations.
This slowdown mirrors a broader cooling in U.S. manufacturing. According to the Bureau of Economic Analysis, spending on new factory buildings declined in both Q1 and Q2 the first consecutive drop since 2020. Just two years ago, following the IRA’s passage, manufactures investments surged at their fastest pace since 1978.
Although the U.S. economy grew 3.3% in Q2, the ongoing decline in manufacturing investment raises questions about long-term economic resilience. If clean tech and advanced manufacturing continue to struggle, the nation’s growth may look strong on the surface but risk becoming unsustainable in the future.
