Desert Winds And Electrical Energy Essay

Desert Winds and Electrical Energy

     The energy of the wind can be channeled into other forms of energy besides the energy used as an erosional agent. This is especially true of desert winds. Today, some desert wind is used to make electricity.

     Wind velocity is affected by air temperature. When air warms and cools, it changes density, which creates air pressure differences that cause wind. In the desert, temperatures may range from 40º F at night to more than 120º F in the daytime. Because of this temperature fluctuation, wind is generally stronger in desert areas.

     There are many windy areas in California. It is usually windier during the summer months when wind rushes in from cooler areas, like the ocean to replace hot rising air in California’s deserts.

     In Southern California, the hot air from the desert goes up and out over the Coast Range, reaching seaward. When it cools off it descends and flows back toward the land and re-enters the desert through such loop holes in the Coast Range as the San Gorgonio Pass – the old Puerta de San Carlos – above Indio. The rush of wind through this particular pass is quite violent at times. For wind is very much like water and seeks the least obstructed path. Throughout the San Gorgonio Pass there are wind-eroded ledges attesting to the violent winds that pass through it.

     The San Gorgonio Pass has Mt. San Gorgonio on the north and Mt. San Jacinto on the south. Both mountains are approximately two miles high. Mount San Gorgonio rises 11,499 feet. Mount San Jacinto is 10, 804 feet high. San Gorgonio has been described as the tallest hill in the United States, even thought it is a mountain. This is because its peak resembles the rounded knoll of a hill. San Jacinto has the fifth highest rock wall on the North American continent. With its feet in the blazing desert, it rises abruptly over 10,000 feet. The San Gorgonio Pass is the deepest pass in the continental 48 states. The pass opens up in the east to Cabazon and is the gateway to the desert.

     The San Gorgonio Pass was a prime candidate for wind turbines as it is one of the three windiest areas of the state. California provides about 30 percent of the world’s wind-generated electricity. The San Gorgonio Pass has more than 3,500 wind turbines; many are massed on the floor of the...

Windmill Energy is not an Acceptable Energy Source Replacement for California

1491 words - 6 pages speed wherever the pressure is located. The California coast is a major advantage to produce wind energy using windmills. The ocean gives off a lot of wind, and this wind is used to accelerate the job of the windmills. Miller has also stated that Wind Energy 4 during the summer, the wind speed in central California is fairly distinct (1980). Luckily, wind is not only produced by the ocean but by coastal mountains, the desert, interior mountain

The Pros and Cons of Wind Energy

1646 words - 7 pages . Horizontal axis wind turbines are exclusively used in larger “utility-scale” turbines. They also have a wider operating speed range and are self-starting. A horizontal axis wind turbine consists of a blade or rotor, a drive train, a tower, and other equipment including controls, electrical cables, ground support equipment, and interconnection equipment. A blade or rotor converts the energy in the wind to rotational shaft energy. The rotor/blade converts
