This project aims to provide The Wilderness Society (and interested stakeholders) with a series of analyses and accompanying tools for evaluating proposed utility-scale solar energy facilities in the Mojave and Colorado Deserts of California. The overall goal is to develop recommendations and guidelines that will enable TWS and other stakeholders to comprehensively evaluate potential impacts of utility-scale solar developments on the California Desert. The project spans six different focus areas: (1) ecological impacts of solar development on species, natural communities, and landscape-scale ecological processes; (2) economic analysis and distributed generation case study; (3) GIS spatial analysis of site suitability; (4) evaluation of the solar-permitting process and policy incentives/disincentives for solar development on public lands; (5) socioeconomic impact analysis, stakeholder survey, and case study; and, (6) technology impacts on the environment and resource and infrastructure needs of proposed technologies.
