What Is Wind Energy All about - Essay Example This essay will talk about one form of renewable energy which is wind energy. As stated earlier, wind energy is a form of renewable energy. Renewable energy sources are those that are replenished naturally on a human timescale. Examples of renewable energy are geothermal power, wind energy and sunlight. Wind energy is used to produce electricity when fast-moving air called wind, hits propeller-like blades attached to a rotor. The rotor is coupled to a dynamo-like generator to produce electricity. The generator produces electricity through electromagnetism in its coils. The propeller-like blades, the main shaft and the generator form a unit that is known as a wind turbine. Wind turbines are usually mounted on towers to harness most of the energy of the moving air. These turbines are usually erected in areas that are very windy and are usually outside towns and areas of dense populations. The energy from wind has been harnessed both residentially and commercially. People have used small wind turbines to generate electricity for their own personal use. The generation of electricity has also been done for commercial purposes but in most cases, the energy from a given wind farm is normally used to serve a specific area. Divided opinions have been witnessed by the use of wind energy. Some people have supported the increased tapping and use of wind energy. They argued that wind energy is a great idea and way of generating cheap electricity. However, there are those who have not agreed with this are a bit sceptical when it comes to wind energy. The divided opinions have been generated by the various pros and cons associated with wind energy.
