I've watched the windmills sprout up over the past decade in mid-Michigan, first near Ithaca, then spreading North to my own summer home back yard in Rosebush.
But windmills in Michigan are designed so that they will work in snow, icing conditions, and extreme cold. I doubt that 10 degree F weather was taken into account when designing windmills in Texas.
We also don't put our water softeners outside of our house in Michigan, but it is often done in Texas.
