Renewable Energy Sources Like Wind Power
522 wordsFor many years, people have been harnessing the power of wind. Wind propelled boats down water and simple windmills were used to pump water and grind grain. But credit goes to the Dutch who refined windmills so that they could drain swamps and lakes, and in the 19th century, settlers took this concept with them to the New World. There, windmills were used to pump water for farms and ranches, and later to generate electricity for homes and industry purposes. Industrialization caused a decrease in...

Geological Age Of The San Gorgonio Pass
858 wordsDesert 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 40 o F at night to more than 120 o F in the daytime. Because of th...

Wind Energy
596 wordsFor human development to continue, we will ultimately need to find sources of renewable or virtually inexhaustible energy. It's difficult to imagine this, but even if we find several hundred or even thousand years of coal and natural gas supplies, what will humans do for the next 250,000 years or so after they are depleted? Even the most apparently 'inexhaustible's sources like fusion involve the generation of large amounts of waste heat -- enough to place damaging stress on even a robust ecosys...

Wind Turbine Generators
3,538 wordsIntroduction. Harnessing the natural power of the wind is by no means a new concept. Asides from sailing, wind power has been utilised for many thousands of years, principally for agricultural purposes. Basic windmills are thought to have been used in Persia (now Iran) as early as the 7th century AD. Their ability to make use of otherwise untapped energy sources without the needs and costs of other alternatives, ensured that they remained the machines of preference in several industries througho...

Wind Farm Data Tower
1,242 wordsHenry David Thoreau's book CAPE COD describes the natural beauty of the Cape. Thoreau, if alive today would be enraged because of Cape Wind Associates' plan to build 130 wind turbines. These turbines would stand 417 feet high on 24 square miles of Horseshoe Shoal (see attachment A) in Nantucket Sound. If approved this wind farm would be the nation's first and the largest in the world. The average output could provide about 75% of the Cape's usual electric demand (web visited March 3, 2003). Howe...

Turbines Use Wind Energy
1,854 wordsWhat is Wind Energy? Wind Energy is defined as an alternate source of generating electricity. Wind Energy is energy obtained from moving air. The motion of wind results from the heating and cooling of the earth. Wind power is used from a wind turbine, and electricity is generated by its magnetic fields. It is normally turned into useful energy by the action of wind currents on moving surfaces, such as, the sails of a ship, or the blades of a wind turbine. Wind Energy is the fastest growing energ...

Maximum Efficiency At Different Wind Speeds
1,212 wordsAlternate Sources Of Electri. Essay, Research Paper Alternate Sources of Electricity: Wind Power Wind is created from an unequal heating of the earths atmosphere therefore wind is an indirect form of solar energy. Convection currents, which occur due to the fact that warm air rises and cooler air drops, produces this cycle of air or wind. Some of the suns energy directly heats the air but mostly the heat is transferred form the earth into the atmosphere. Between 1 – 2% of the solar radiati...
