Electric vehicles have powered United States clean-technology spending to a historic high. A fresh quarterly review from the Clean Investment Monitor shows total outlays of US$75 billion (C$102 billion) in the third quarter of 2025, up nine per cent from the spring and the biggest three-month tally on record.

More than half of that money, US$41 billion, came from retail purchases of zero-emission vehicles, with passenger-car sales alone hitting US$31 billion after a late-summer buying surge. The rush reflected a scramble to claim the federal electric-vehicle tax credit before it expired on Sept. 30.

Analysts say the spike lifted clean technologies to 5.3 percent of all private investment in structures, equipment and durable goods, also an all-time peak for the sector.

Tax credit expiry sparks rush

The monitor, a joint project of Rhodium Group and MIT, links the sales jump to shoppers using the soon-to-end US$7,500 incentive. Car dealers reported empty lots in September as popular models cleared out. Retail spending on heat pumps and household batteries, which still qualify for breaks until Dec. 31, rose more modestly. Colin McKerracher, head of clean transport research at BloombergNEF, put the moment in context.

“Despite these positive tailwinds, we see slower EV adoption in the short and long term due in large part to the changing landscape in the US,” he said in a June outlook report. His team predicts 14 million fewer American EV sales between 2025 and 2030 than it projected a year ago, hinting that the record quarter may stand for some time.

Manufacturing picture turns mixed

While drivers opened their wallets, factory builders tapped the brakes. Manufacturing investment fell for a fourth straight quarter to US$10 billion, 26 per cent below the same period last year, as battery and assembly projects were shelved.

Developers cancelled another US$2 billion worth of proposed plants, continuing a trend that has eroded confidence along the supply chain. Energy-generation spending told a different story. Utility-scale solar and storage pulled in US$24 billion, and wind farms logged their strongest quarter since 2020. Even so, policy uncertainty has cooled announcements of future projects, leaving planners wary of a cliff once remaining consumer credits end.

Wider cleantech outlook still bright

Global observers argue that the broader transition remains on track. International Energy Agency executive director Fatih Birol noted earlier this year that “energy security [is] a key driver of the growth in global investment” to a record US$3.3 trillion, with clean assets set to draw two-thirds of that total.

The latest United States numbers support his view, though they also show how heavily progress can hinge on temporary incentives. Heat-pump and rooftop-solar credits will lapse soon, raising the prospect of another quarter-end dash and a subsequent dip.

For now, the third-quarter figures confirm that consumer appetite, when aligned with policy, can mobilise billions for low-carbon infrastructure in a matter of weeks. Observers north of the border are watching closely as Ottawa fine-tunes its own electric-vehicle incentives to keep Canadian demand from falling behind a fast-moving market.
