A developer in Oklahoma has built a zero-energy home prototype for $200k. It’s a combination of energy efficiency, and photovoltaic and geothermal power production, mostly built with readily available off-the-shelf components. That’s fantastic.
“Ideal Homes built the first zero energy home in the country priced under $200,000. The modest one-story, three-bedroom, two bathroom home produces as much energy as it consumes in a year, achieving net zero energy consumption.”
