Investment in US clean energy infrastructure has stalled, with $83 billion in wind and solar projects now facing cancellation or significant delays.

The freeze stems from the Trump administration’s decision to slash federal subsidies for renewable energy, a policy shift that has forced developers to reassess the viability of planned capacity additions.

The withdrawal of state support has created immediate uncertainty for the sector.

Projects that relied on tax credits and grants to bridge financing gaps are now at risk of being shelved indefinitely.

This development marks a sharp reversal from previous years, when federal incentives drove a surge in renewable capacity planning across the United States.

For markets, the signal is clear: the policy tailwind for US renewables has turned into a headwind.
