The Trump administration has launched a national security probe into imports of wind turbines and their components — a move that could ultimately lead to higher tariffs for wind energy.
The probe, which marks the latest salvo in the administration’s efforts to stymie wind energy, was announced in a Federal Register notice Thursday.
“On August 13, 2025, the Secretary of Commerce initiated an investigation to determine the effects on the national security of imports of wind turbines and their parts and components,” says the notice.
It does not explicitly lay out the reasons for or evidence behind the probe, and the Bureau of Industry and Security did not immediately respond to questions from The Hill.
But the administration requested information from the public on topics including the role of foreign supply chains, the impact of foreign government subsidies and predatory trade practices and whether there’s any ability to weaponize foreign-built wind turbines and their parts.
The investigation was initiated under section Section 232 of the Trade Expansion Act. Such probes are supposed to determine the national security impacts of imports and allow the administration to make adjustments, including tariffs, based on their results.
It comes after the administration already earlier this week increased steel and aluminum tariffs for hundreds of products including wind turbines.
The probe was being launched as President Trump continues his efforts to stifle renewable energy buildout, including by repealing subsidies and setting up new hurdles for approval.
This week, Trump said in a post on Truth Social that “We will not approve wind or farmer destroying Solar.”
