Do you have enough wind or solar exposure to go Off-Grid?

I found an interesting post on Off Grid Living, a blog about conserving energy and living off the main power grid. They suggested using an online watt estimator based on your locality zip code to estimate whether you have enough exposure to produce more power than you need.

The calculations are based on estimates by the Department of Energy. So if you visit the site MyWattsEstimator and enter your State and Zip Code you will get your on-site renewable energy potential.

I’ve often asked my husband about this since we live in Northern Ohio where it’s cold and overcast 4 to 6 months out of the year.

I went to the site and this is what my report was (I had to use an address from inside town because the system could not find my rural address):
