A period of extremely cold, windless weather has brought home to the British the drawbacks of relying on wind power and the need to keep a supply of natural gas in reserve. While the cold spell has strained natural gas supplies, leading in some cases to cutoffs to industrial users, it also has highlighted the unpredictability of wind power. Although Britain’s wind farms are supposed to provide 5 percent of the country’s electricity, they were in fact only providing 0.2 percent during the recent run of frigid, still days.
