...energy superheats the oil, which is then used to boil water into steam. The steam runs turbines, which generates electricity. The technology is as simple as any fossil fuel plant, and cheaper by material than the technologically complex photovoltaic panels. It can be more easily built up to utility-scale than photovoltaic solar - Acciona's plant, which began operation last year, produces 64 megawatts of electricity for the utility company Nevada Power, enough to light up 14,000 homes. The company's Spanish competitor Abengoa just announced a plan to build a 280-megawatt solar thermal plant outside Phoenix, which...
