Correct Answer

During 2020, amid the Covid-19 outbreak and stay-at-home orders, wind provided 3.2% of all U.S. energy, including 8.4% of all U.S. electricity. Because wind speeds fluctuate and are sometimes not strong enough to drive turbines for days at a time, most wind power capacity must be backed up by other energy sources to generate electricity when the wind doesn't blow. This is expensive and limits wind production in the U.S. and throughout the world. In Germany, which subsidizes wind and solar more aggressively than the U.S., the average price of household electricity is about three times that of the United States. Reliance on wind as a major energy source can also contribute to electricity blackouts during dangerous weather conditions.
