A few years ago I was traveling from Arizona to Nevada and chanced upon hundreds of
acres of commercial windmill electric generators. There were more than I would even try
to count. I couldn't tell what material the poles they were made of, but expect concrete
because of their size. They were huge, with blade diameters probably over 20 feet and the
towers 10 times that. I noticed a group of maybe 20 in a rather isolated area that had
obviously either been blown down or demolished. I happened to see a power company
truck exiting a road that lead to the whole area and stopped him and asked what had
happened to the downed towers. He said the weather service said a "micro burst" blew
them down. Micro bursts have only been discovered in the last few years and many
previously reported tornado damage areas were actually caused by micro bursts,
associated with severe thunder storms, which contain short duration winds of as much as
200 miles per hour.
So, from that experience, any wind mill that can't be disassembled and stored in a safe
place prior to the pole shift wouldn't have a chance.
