Energy-positive homes in Massachusetts
Carter Scott designs superinsulated net-zero and positive energy detached houses in Massachusetts with Mitsubishi mini-splits, Navien instant water heaters and solar panels. He says solar PV now costs just 80 cents per watt.
A few homes came with enough panels to power the house and an electric car for 30,000 miles. He’s working on more than 100 net-zero or better homes that cost just $1.40 per square foot to build.
