Ok. So I'm looking into other energy alternstives for our homes. When we built the place we went with effecient lighting, windows, heating and air and water heating units, insulation and what not. But are still very much on the grid. Eventhough it's illegal here to be so far off the grid that youre not hooked to it we would like to use it as little as possible. Id be interested in hearing yalls experiences with geothermal and solar. Wind really isnt an option as the area ig Iowa I live in does not get enough wind to justify the cost.
