Home to more than 100,000 solar installations, San Diego is one of the nation’s leaders when it comes to renewable energy. But according to a just-released report, there are many more locations where the sun’s energy can be harnessed. A nonprofit based in Northern California released a “solar siting survey” that identified 500-megawatts of locations with potential for large-scale solar deployments within the city limits of San Diego and pinpointed more than 120 prospective locations that could be home to projects of a minimum of 1-megawatt.
