Some people suggest wind energy as an alternative to fossil fuels to produce electricity. Texans recently learned that wind energy has a major defect. It is undependable. Reuters reports that electricity was cut off to interruptable customers on Feb. 26, after wind power output dropped from 1,700 megawatts to 300 mw as demand was increasing due in part to a cold front moving into the area. The grid operator for Electric Reliability Council of Texas (ERCOT) was responsible for cutting the power .
Wind generators need a certain minimum amount of wind to operate, but if wind speed is too high the equipment can be damaged and needs to shut down until wind speed drops.
