The Trump administration is doubling down on efforts to delay the buildout of wind energy, this time focusing on land-based wind projects, according to a clean energy trade group.

Citing national security risks to US military readiness, the Pentagon is slow-walking the reviews of 165 land-based wind projects, according to the American Clean Power Association, the leading group representing wind and solar developers.

The Pentagon, in conjunction with the Federal Aviation Administration, has historically reviewed large wind projects, ensuring towering turbines don’t mess with radar or flight paths. Typically, those reviews have been resolved quickly, but standard times started stretching longer starting around August 2025, the association said. Some reviews of individual projects have now gone over six months, according to a letter ACP wrote to the Pentagon asking about the delays, which was shared with CNN.

ACP CEO Jason Grumet said in a statement the Trump administration was “abusing the current permitting system.”
