Two Sinton boards met Monday night and declined to approve variances for construction of turbines at Sinton High School. A 2011 city ordinance regulates the building of wind turbines in Sinton, located 25 miles north of Corpus Christi.
Supporters say the energy generation would help the school district save money, plus the turbines could be a learning experience for students.
Critics have questioned the noise factor, raised property value concerns and complained that the towering turbines could be eyesores.
The Sinton Planning and Zoning Commission and the city's Board of Adjustment separately rejected the wind turbine proposals.
Federal funds would have helped pay for the turbines.
