[en] An analysis was made of the economic, environmental, and sociocultural impacts of alternative electric generation options on California, surrounding states, and the U.S. as a whole. The relative costs, risks, and benefits of passage or non-passage of the California Nuclear Power Plants Initiative (which would put constraints of nuclear electric generation) were studied. Electricity supply and demand are discussed, including information on capacity requirements, fuels requirements, alternative demand growth patterns, reserves and reliability factors, and supplies of fossil fuels. Electricity price effects, capital-spending patterns, specific sectoral impacts, employment implications, and long-run economic growth effects of alternative scenarios are covered. Environmental impacts of alternative cases and sociocultural impacts are studied
