Wind Turbines : An Alternative Energy Essay

1265 Words null Page
I have researched how turbines assist in generating alternative energy. I found my research primarily from the Internet from sources such as the U.S. Department of energy. I then noted what a wind turbine does to help generate energy, and why it is used as an alternative energy. I also found disadvantages to using fossil fuels, and why it is important to use alternative energy like wind. I then researched how the wind turbine worked and what each specific component of the turbine did. Before researching, I hypothesized that wind turbines did very little to help the Earth 's crisis of burning fossil fuels, but after researching, I discovered that many farmers and ranchers are using wind turbines to help conserve energy, and they are doing so at a very low cost. Using wind turbines can benefit everyone, and since it is a clean renewable energy, it will not pollute the Earth 's atmosphere.
A turbine is a machine, containing a rotor that has blades. The turbines are powered by momentum, and the kinetic energy is converted to mechanical energy. A turbine works by using wind to make energy, which is opposite of a fan. There are two basic groups of turbines, the horizontal-axis variety, and the vertical-axis design. There are also many sizes of turbines ranging from 100 kilowatts to several megawatts. A turbine is constructed of many parts, including an anemometer, two or three blades, a brake, a controller, a gear box, a generator, a high-speed shaft, a low-speed shaft, a nacelle,…
