Wind energy comes from the mismatched heating system of the planet that runs all day and night, heated and cooled by the sun. They are also come as effect of the different between land and sea heat temperature, and natural barriers such as mountains.
The wind power goes back at least 5000 BC, when it was first being used for the movement of boats on the Nile. In 200 BC, it is reported that homemade windmills pumping water and grinding grain in China and in the Middle East.
The first wind turbines for producing electricity, known as generating turbines is called, appeared in Denmark around 1890. How doese wind energy works? The turbines operated on a simple principle: the movement of two or three propeller, which then turn is connected to an electrical generator. When the wind blows, the rotating propeller is spinning and will create electricity generator. A wind turbine (a familiar axis-horizontal shaped unit, usually mounted in a tower of 75 meters height. A wind turbine controller is presented to enable the propellar to stabilize its movement This height is and ideal height to get faster wind movement. There is some other small vertical axis wind turbine that is not mounted on towers; this is specially designed for low-speed of the wind.
The wind is a huge free energy resource and inexhaustible.
Wind energy benefit us by cut down energy consumption from primary energy electricity supply like natural gas, coal, and to a lesser extent, oil. Knowing that all fossil fuels consumption will increase over the next 20 years earlier, and the price is skyrocket, hence it is necessary to cut down global energy consumption wherever possible.
The advantages of wind power are numerous and we will observe some of the main ones in this article. The most apparent advantage is that wind power electric is altogether free. Of course first you should invest in building a power generator. The cost to built power generator is considered a small investment compared to the large utility bills your household is getting every month. Furthermore maintenance costs are pretty low-both time and money required for windmill upkeep.
Once a wind turbine, wind power requires no fuel.
The cost in wind energy is such as solar and geothermal energy. Most of the cost are for the construction of the fan and wind system. Then after it is fully operated, the operation and maintenance costs are minimal and predictable. It is also a system with low maintenance and easy to manage. When it comes to financing of wind-energy projects, it may be low risk compared with fossil fuel plants, where fuel costs are volatile and unpredictable, and therefore risk of investment is high.
Wind power requires no water as opposed to conventional power plants of any kind that take large amounts of water. These power plant systems need several billion gallons of water per day, which is used in the refrigeration cycle to convert water into steam and cycle back into water. This is become some limitation to the area where water is not abundant or in the summer condition, where the water supply is not available. This is the case as in 2006 and droughts and like the power of South America experienced in 2007 due to a large defect in the water. Most power plants should be shut down because lack of water.
The wind power can be advantage point in this case because a diversified energy mixes. The more varied the supply, the better the result of energy output. Energy generated through wind production is relatively predictable. The const involved is relatively stable. This helps the effects of cost containment volatile fossil fuels. The wind energy industry is an important economic incentive and a source of well-paid jobs.
