I live in a state where alternative energy is a hot topic. There are solar panels here & there. Wind projects have been proposed & rejected in many places. Instead of posting a contemporary example of alternative energy I am going to give you this photo of an old windmill which probably dates to a time before rural farms had electricity.
It is in a field adjacent to my home. The field is on the market as two building lots. I am selfishly enjoying that it still open land for now & that I can see the old windmill out a window of my bedroom each morning.
