Less than a week after the New York Times celebrated Texas’ dominant position in wind power, a cool, still day dawned. The cold weather drove residents to crank up the heat, but the lack of wind to turn turbines pushed the state’s electric grid into emergency mode. On Tuesday night, the Electric Reliability Council of Texas cut off power for 90 minutes to those customers who had agreed to accept power interruptions. And it was a full three hours before everything was back to normal.
All of which proves that while, cheap, clean and renewable, it’s pretty hard to know which way the wind will blow.
