10 Houses that Actually Produce More Energy than They Consume

Net Positive Victorian Retrofit

This 104-year-old Victorian home in Minneapolis underwent a net-positive retrofit in 2015. For the homeowners, the long and intense process was worth it not only for the comfort of knowing they’re helping the environment; but they are now able to sell back the home’s surplus energy to their local utility company for about 20 cents per hour. In the first year, the system produced about $3,000 worth of electricity!
