The Trump administration claims wind turbines pose a national security threat. The industry says it's pure politics.
Excerpt from this story from Grist:
Wind turbines can confuse radar systems on ships and aircraft. Their massive rotating blades create a âblade flashâ on radar screens, while their steel bases reflect electromagnetic waves, making it difficult to distinguish the turbines from aircraft or other objects. Thatâs a problem for the military, which relies on radar for threat detection and navigation. For over a decade, the Pentagon has used a permitting program to review proposed projects and mitigate the effects on radar. Wind developers are required to submit project proposals, address military requests, and in some cases pay to upgrade radar systems to tune out the turbines.Â
But now, in a world where small, deadly drones can zip through wind farms, the Pentagon says those upgrades may not be sufficient.Â
For almost a year, the Pentagon has effectively frozen the permitting process for at least 155 new wind projects in 24 states, citing drone concerns, according to research from the American Clean Power Association, an industry advocacy organization. As long as the freeze persists, developers say, no new wind projects can begin construction. The Pentagon has not revealed when or if it will resume approving new projects.Â
Wind developers say theyâve incurred $2 billion in additional costs as a result of the freeze and that the administrationâs new narrative is just the latest excuse to shut down their industry. Some may already have missed a July 4 construction deadline to qualify for federal tax credits under the One Big Beautiful Bill Act, the 2025 law that phased out several clean energy incentives.
âWithout [Pentagon approval], wind projects canât get financing or insurance, and so effectively it has frozen the entire process,â said Dave Belote, a wind energy consultant and former director of the Defense Department subagency that greenlights wind projects during the Obama administration.Â
Over the past year, the Trump administration has separately been trying to halt the construction of offshore wind projects in federal waters, in part citing similar national security concerns. The Interior Department froze leases for five offshore projects last year, and the developers sued the agency over the decision. In a series of rulings earlier this year, judges struck down the federal stop-work orders even after viewing classified material that administration officials claimed illustrated that wind turbines created national security threats by affecting radar. After the court losses, the Trump administration took the extraordinary step of paying developers a combined $2.6 billion to cancel more than 11 gigawatts of offshore wind projects.Â
