Nevada Solar One, a 64-megawatt solar-thermal power plant in Boulder City, Nevada, became fully operational in June 2007. The plant, among the largest in the world, features parabolic-trough mirrors that focus sunlight on tubes filled with a synthetic oil, heating it to over 700°F (370°C). The hot oil flows to a central plant, where it passes through a heat exchanger, generating the steam that drives a turbine to create electricity. The energy produced on the 300-acre site will power about 15,000 average homes and will be delivered primarily during peak demand times—summer afternoons and evenings.
