Turbines are generating less than a 10th of what they’re capable of. Wind power — a key source of electricity in Texas — is being sidelined just when the Lone Star State needs it most, with turbines generating less than a 10th of what they’re capable of. A scorching heat wave is pushing the Texas grid to the brink. Power demand is surging as people crank up air conditioners. But meanwhile, wind speeds have fallen to extremely low levels, and that means the state’s fleet of turbines is at just 8% of their potential output. Texas may be America’s oil and gas hub, but it’s also long been the country’s biggest wind-power state. The renewable energy source has become highly politicized: Some critics blamed frozen wind turbines for the Texas grid’s failure during a deadly winter storm last year, even though disruptions at plants powered by natural gas were […]
