Like most other sources of alternative energy, the wind can be intermittent. It does not blow uniformly, so power output from wind turbines rises and falls. And when the wind doesn’t blow at all, output drops to zero.

Intermittency is not much of a problem now in the United States, since there are relatively few wind farms and plenty of interconnected conventional power plants to pick up the slack when wind output falls, keeping the power supply stable. But if the proportion of electricity supplied by wind were to grow to, say, 20 percent or more, it would become increasingly difficult to handle the fluctuations in output.
