From massive wind farms generating power to small turbines powering a single home, wind turbines around the globe generate clean electricity for a variety of power needs.

Wind turbines are soaring to record sizes. The average rotor diameter of turbines installed in 2017 grew to 370 feet, up 135 percent since 1998–1999.

Among the Federal Aviation Administration’s (FAA) main priorities is to keep all users of our national airspace safe. To maintain the safest aerospace system in the world, the FAA must make sure the national airspace is navigable and free of obstructions.

When anyone proposes new construction or proposes to alter existing structures near airports or navigational aids, the FAA determines how the proposal would affect the airspace.
