A college in Illinois I had never heard of has its own wind turbines, which of course they decided on getting to show how green they were, but it turns out they were a very bad investment. They need to be repaired often, and one even got struck by lightning. See here. So, they are getting rid of them.
I have to say that when I have driven by wind farms, there always seems to be at least one of them that is not turning. And given how big they are, I can’t imagine they are cheap to repair.
