Emerging technology can ease the problem of wind farms causing interference with air-traffic control systems. But deployment of that technology in the U.S. has been slowed by questions over authority and cost.
Since 2006, radar maker Raytheon and National Air Traffic Services, which provides air traffic control in the U.K., have been working on a project to upgrade air traffic radar so it can distinguish between aircraft and wind turbines' spinning blades. Concerns over the disturbances turbines can cause on air traffic control systems are already stunting the growth of wind power: radar and wind turbines conflicts derailed nearly as much as the total amount of installed wind power capacity in the U.S. last year.
