Wind power in Illinois
I was driving home from Chicago and left early and it was dark for a couple of hours. Traveling down I 55 I noticed quite a few wind generators with red flashing lights. There seemed to be hundreds. The red lights were flashing in unison every two seconds. When I got home I decided to do a bit of research and learned that there are over 3,000 wind generators in Illinois.
I also learned that the cost of producing electricity (including maintenance, capital cost and land leases) is just over 3 cents per KWH. Check your bill and see what you are paying.
