  • Wind farm producing electricity at Altamont, California. Wind turbines. Wind Turbines. View of a wind farm with several wind turbines each with 3 spinning rotor blades. Wind power is used to drive a turbine for the generation of electricity. The electrical energy produced from a turbine is proportional to the cube of the wind speed. Thus, a 10-meter per second wind will produce 8 times more energy than a 5 meter per second wind. Wind turbines vary in size from large generators with a 1-3 megawatt capacity to small machines producing only a few kilowatts. (1985).

  • Solar energy electrical generating power plant in the Mojave Desert near Barstow, California. Solar One consists of a circular arrangement of 1, 818 mirrors, each measuring 23x23 feet (7x7 meters). These mirrors focus the sunlight onto a huge central receiver, which sits atop a 300-foot (91 meter) tower. The mirrors are computer controlled to track the path of the sun. Water is pumped through the receiver and heated to a temperature of 960 degrees Fahrenheit. The resultant steam runs a turbine, producing 10 megawatts of power for eight hours a day. (1985).

  • Solar energy: Solar Plant 1. Warner Springs, California. Solar Plant 1 was the largest privately funded solar powered electrical generator in the world when it was built in 1984. Built by LaJet Energy Company of Abilene, Texas , SolarPlant 1 is a five megawatt distributed receiver facility. There is no central tower to soak up sunlight reflected from a broad field of glass mirrors. Instead, each of the 700 concentrators--consisting of 24 plastic mirrors kept in shape by a vacuum pump- reflects sunlight into its own receiver. Water is pumped through the receiver, which turns to steam to drive a turbine to produce electricity. (1987).

  • 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 thus super-heated to 391 degrees Centigrade, is used to boil water for steam turbine generators in one of five power plants. (1985).

  • Alternative Energy: Mesquite Lake Cattle Manure Power Plant, California. The Mesquite Lake Resource Recovery Project is the world's first cattle manure-fired, commercial scale power plant. The plant burns cattle manure from nearby feedlots. The manure was becoming a serious waste problem because it was of limited value as a fertilizer in the area. In many cases, feedlot owners had to pay to have the manure removed. At Mesquite Lake, this waste material is burned and the heat generates steam, which drives a turbine/generator and produces about 17 megawatts of electrical power. After supplying plant needs, 14-15 megawatts are sold to Southern California Edison. This is enough power to supply the needs of a community of about 15,000 to 20,000 homes. (1990).

Built by LaJet Energy Company of Abilene, Texas , SolarPlant 1 is a five megawatt distributed receiver facility. There is no central tower to soak up sunlight reflected from a broad field of glass mirrors. Instead, each of the 700 concentrators--consisting of 24 plastic mirrors kept in shape by a vacuum pump- reflects sunlight into its own receiver. Water is pumped through the receiver, which turns to steam to drive a turbine to produce electricity. (1985).

  • Solar energy: Solar Plant 1. Warner Springs, California. Solar Plant 1 was the largest privately funded solar powered electrical generator in the world when it was built in 1984. Built by LaJet Energy Company of Abilene, Texas , SolarPlant 1 is a five megawatt distributed receiver facility. There is no central tower to soak up sunlight reflected from a broad field of glass mirrors. Instead, each of the 700 concentrators--consisting of 24 plastic mirrors kept in shape by a vacuum pump- reflects sunlight into its own receiver. Water is pumped through the receiver, which turns to steam to drive a turbine to produce electricity. (1985) .

  • Dawn mirrors facing east to meet sun. Solar energy electrical generating power plant in the Mojave Desert near Barstow, California. Solar One consists of a circular arrangement of 1, 818 mirrors, each measuring 23x23 feet (7x7 meters). These mirrors focus the sunlight onto a huge central receiver, which sits atop a 300-foot (91 meter) tower. The mirrors are computer controlled to track the path of the sun. Water is pumped through the receiver and heated to a temperature of 960 degrees Fahrenheit. The resultant steam runs a turbine, producing 10 megawatts of power for eight hours a day. (1982).
