Google Brings Renewables Home

Like SESSA, Google is also getting behind the push for home and building-scale consumer renewable energy generation with the recent launch of an initiative which assists American consumers to assess the rooftop solar potential of their homes, a clear sign that rooftop renewables can now be considered mainstream. Google Sunroof allows one to drill down to a particular building or house and factors in local solar irradiation data and rooftop orientation in order to arrive at a projected generation potential.
