Wind turbines Free Essay Example, 2750 words

History has provided immense details regarding wind turbines and how they produce electricity. History has even helped in learning that wind turbine helps in the production of energy and can help in decreasing the use of harmful fossil fuels that is used in electricity production and can change the field of energy by providing safe and environment friendly energy to consumers throughout the world. Body What Are Wind Turbines Used For The historical knowledge of wind turbine clearly states that wind turbine can be used for various tasks. For example wind turbines have been previously used for the purpose of draining Rhine Delta. But the main purpose due to which wind turbines are gaining popularity and have remained popular for several years is that wind turbines have the ability to generate electricity that is safe for the environment. In order to identify whether wind turbines produce eco-friendly energy or not, it is essential to understand how wind turbines work. How Wind Turbines Work The first step in the operation of wind turbine is the rotation of the rotor blades that are connected to the turbine and these blades rotate as wind passes through them.

The length of the blades is very essential for production of more energy. The higher the length of these blades, the higher will be the production of energy. The movement of these blades is essential for the turning of a shaft that is located within the box that is attached on top of the wind turbine. The movement of these shafts is essential for the gearbox to work which is essential for the increase in the speed of the rotation of the blades. The box that is located above the tower eve comprises of a generator that is essential for the conversion of the energy of blade rotation into electricity (Energy. gov, 2015(a)). The wind turbine is connected with a transformer which is used to convert the electricity being generated into voltage that has been set to be distributed to the households and organizations that are connecte d with the national grid and the national grid is powered by the transformer. The blades of a turbine are connected to a tower this tower is at least 75 meters long and is placed in an upright position so more wind energy can be consumed. Wind turbines even comprise of a monitor that is useful for the detection of the speed as well as the direction in which the wind is blowing.
