Among other things, wind power lacks one characteristic for being economical, that is economics of scale for each unit of generation.
Conventional steam and gas generating units come in large sizes, say 100 MW and larger. Build it stout and reliable and keep it on-line. It pays for itself by using affordable fuel and generating with large MW-Hour maintenance intervals.
Wind power doesn't come with a single windmill in 100 MW and larger sizes. Despite having free fuel, the MW-Hour maintenance interval is comparatively small, and the generating equipment is exposed to high winds, rain, hail, and lightning.
Windpower lacks ALL characteristics for being economical...tho' highly entertaining.
