Windmills and Solar Energy

I've always thought that solar and wind energy is the way to go because you can generate your own electricity wherever. I have been speaking to a friend in Illinois about how great it is and he spoke to a friend... His friend really thought it's a great concept but was unsure if there was any reasonably priced windmills that he could set up in Illinois. I thought I'd put this in my blog in case someone in Illinois ever reads this and could contact me. I also thought perhaps if I keyed in the correct words the answer might appear in the ads that often match up with what I write. I thought it's worth a try. Meanwhile if anyone does know of a reasonably price company that provides wind and Solar energy devices please let me know. Thanks.
