Large-scale deployment of solar power projects in California could provide significant economic, air-quality, and labor benefits, according to a study released by the National Renewable Energy Laboratory. The report, conducted by Black and Veatch under contract with NREL, compared the costs and benefits of building out between 2,100 MW and 4,000 MW of solar power between 2008 and 2020 to those of the same output from simple- and combined-cycle gas-fired plants. Every dollar invested in these concentrated solar projects adds about $1.40 to gross state output, states the report, Economic, Energy and Environmental Benefits of Concentrating Solar Power in California. In contrast, every dollar spent on natural gas-fueled generation adds between $0.90 and $1.00 to the gross state product, it continues. It is available at nrel.gov\/docs.
