New York Times reports that Outgoing Mayor of San Francisco, Gavin Newsom, aims for 100% renewable energy by 2020 for San Francisco (2010): “Outgoing Mayor Gavin Newsom (D) last week launched an initiative that he says will result in 100 percent renewables to meet this city's power demand within a decade. Newsom, who becomes lieutenant governor of California next month, announced the program during a speech commemorating the completion of the Sunset Reservoir Solar Project, which at 5 megawatts is the largest municipal solar facility in the state. The project was completed last week and covers an area said to be the size of 12 football fields. The plant, owned and operated by Recurrent Energy, triples the amount of solar energy available to the city government here. But Newsom is looking for much more. At the ceremony, he announced a $250,000 grant from the Sidney Frank Foundation that will assess how to meet the city's 950-megawatt peak power demand with nothing but renewables by 2020.” .
