California's goal of generating 33 percent of its power from renewable energy sources by 2020 will be challenging on days when clouds shade acres of solar photovoltaic panels or when thousands of wind turbines spin more slowly during calm weather. However, researchers at the University of California, San Diego are developing sophisticated forecasting tools that will give California electricity distributors advance notice of meteorological changes that affect solar output. The technology is being developed to allow energy suppliers to more efficiently schedule their fossil-fuel fired plants or energy-storage facilities to meet the state's demand for electricity.
