Solar energy: SEGS Solar Plant. Southern California Desert. Solar power. One of the three Luz International solar energy complexes in the Mojave Desert of California, USA. Together these sites, which cover 1000 acres, generate 275 megawatts of electricity, 90% of the world's total grid-connected solar energy production. This installation, located at Kramer Junction, has an array of 650,000 computer-controlled parabolic mirrors which track the sun across the sky, focusing it's light onto tubes containing a synthetic oil. The oil, which is heated to 391 degrees Centigrade, is used to boil water for steam turbine generators in one of five power plants. (1985).
