Wind power is like Ginger Rogers. You know what I mean. It isn’t judged by the same standards as other kinds of electricity generation.
I’m speaking specifically of the reliability of, or variation in, wind over time. Many people live in places where they personally experience highly variable wind, or at least, think they do, so it is easy to assume that wind generators would be sometimes running on full, sometimes standing still, in a more or less random and unpredictable way, but this is not necessarily true. There are regions where wind is much more consistent than people might imagine, though of course it is always somewhat variable. In fact, a bigger problem with wind may be not so much the variation, but the fact that in some regions it is out of sync with energy demands. In some temperate zones, wind may be weak during the day but stronger at night when electricity demands are low (but this can vary from region to region, and seasonally; there are places where winds tend to come up during the day and calm down at night)
