It bears mention that those giant commercial windmills need a minimum wind speed of 11-12 mph before they produce any electricity. Which means that over the vast majority of the 48 contiguous states, there are very few places where they'll have any output for any significant portion of the typical day.
And a stable electrical grid can't tolerate that sort of variability. Which means, unless you want brown-outs (or black-outs) to become a regular feature of your day, you'll need back-up amounting to about 80% of the total "renewable" capacity in the form of conventional power sources (fossil-fueled, hydroelectric, nuclear) operating in a condition called "spinning reserve." And when the output from the "renewables" droops (which it invariably will do, and often), you put the conventional the units (which had been running on spinning reserve) online.
Which means the cost of switching to "renewables" is building, maintaining, and operating conventional power plants of (at least) 80% the capacity of your renewables.
There's also the hare-brained theory of building giant electrical storage battery stations as a buffer to the "renewable's" power droops, but that just further demonstrates the sheer impracticality of the "green energy" fantasy.
Short version: It is all a pipe dream.
