Wind Mills

For Thanksgiving, my family and I are spending the day in Chicago with family. As we were driving up I-65, between snoozing, I saw an area filled with huge wind mill generators. I've seen these before but only three or four plaved in random areas. This was so different, because there were windmills everywhere. The interesting thing about this, was that these wind mills were generating electricity for New Jearsey. I think two things are kinda interesting coming from this. One, are power generating windmills going to be something that are more of the norm to see as your driving down the highway? Two, are the state going to lease lands or partake in practices such as this to raise revenues for their home state?
