Wind comes from wind generators. Wind generators generate wind, hence the name. True story: back in the 1980s I worked at a small electronics company that invented or improved things. We were working on a small wind generator to light up billboards. It also had a battery that it would it would charge up to keep the light on during windless nights. We hook up a prototype. It starts spinning. Then we realize, “wait, there’s no wind… Why is it spinning?” It turns out the battery was powering the generator, making it work like a motor, spinning the blades.
