Existing rooftop space on buildings in California could easily supply the entire electricity needs of the state if it were put to work as a platform for installations of photovoltaic panels.
According to renewable energy start-up Solyndra, the United States has 30 billion square feet of flat rooftop space. The company, which emerged from stealth mode in mid-2008 with $600 million in venture capital and $1.2 billion in customer contracts, is producing a new kind of solar panel suited for industrial rooftops at a factory in Freemont. 1 Regions with vast concentrations of large rooftop space can be found in California, especially in the Los Angles basin. A case in point is the San Bernadino area with several square miles of industrial rooftop space.
