New York Times : Smart materials and technologies are enabling the construction of zero-energy homes, which generate as much energy as they consume over the course of a year. The energy efficiency comes from a renewable energy system, such as solar panels, combined with improved building materials, including spray-foam insulation, dual-pane windows, and LED lighting. Smart thermostats and remotely controlled water heaters help regulate the flow of energy. Since 2013 the US Department of Energy has certified about 700 such homes, and it estimates it will certify another 1000 this year and 3000 in 2017.
