In Fraser, Colorado, there’s a new net-zero energy house that was designed with impressive active and passive building technologies. It’s grid-tied and all-electric, using no fossil fuels thanks to the solar photovoltaics and evacuated tube solar thermal array. But the house isn’t the only thing powered by the sun. The 17-kW array also powers two all-electric plug-in vehicles.
