Or you can install a windmill that is anywhere from $500 to $20,000 to run just about any equipment in your home you want. I was looking and it seems to be the best bang for yer buck is a whisper 200 series 1000w system for $3000. That way if your not using any energy you can sell it back to the electric company (have your meter run backwards) and then using that pump isnt as much of an issue
. I know way more than most people want to spend and wind energy isnt exactly the most efficient thing out there right now
. but it is a thought
