A motion by Supervisor Michael D. Antonovich to ban utility-scale wind turbines in the unincorporated parts of Los Angeles County was approved by the Los Angeles County Board of Supervisors.

County supervisors approved the motion July 14 after more than 50 speakers addressed the matter, with many in support of the ban.

“Wind turbines create visual blight, contradict the county’s rural dark skies ordinance which aims to protect dark skies in areas like Antelope Valley and the Santa Monica Mountains,” Antonovich said.

Edwards Air Force Base and defense contractors also met with Antonovich to discuss what kind of effects wind turbines could cause.

“Both said that wind turbines disrupt flight and weapon test ranges and will negatively affect the research operations,” Antonovich said.
