Wind turbines - Essay Example The earth’s surface does absorb heat at different rates since it is made up of quite distinct types of water and land (School of Earth and Environment, 2014). A good example of uneven heating is found in the daily cycle of the wind. Air over water does heat up less fast compared to air over land. After heated air over land rises up, after which the air that is cooler over the waters rush to replace it (Met Office, 2013). In this way, wind is made. Wind power is generated by use of wind energy that is created by the wind. Towers that have wind turbines, which are mounted on the top, capture it. The three or two blades, which catch the wind, rotate sometimes at a hundred feet or more above the surface of the ground. They are attached to an internal shaft. A generator is spin by the turbine blades through the shaft and as a result, electricity is produced (Energy Saving Trust, 2014). Electrical current produced is produced and a transformer is made use to step up voltage produced , something that makes it possible for electricity to be sent through transmission over distribution lines to businesses, homes, and other users (BBC Weather Centre, 2009). Concurrently, wind power in windmills form has been used for different tasks like pumping water as well as grain grinding for centuries. Currently wind energy use has been widened and generation of electricity generation (Renewable UK , 2014). Wind turbines that generate electricity are of two types basically, determined by the way in which they spin. Most common are wind turbines that spin around a horizontal axis, the way a windmill does. Their blades have a look that of a propeller that spin on a horizontal axis. They do have their main rotor shaft as well as a generator at the tower top, and they have to point into the wind. A wind vane is placed squire with blades (rotor) and is used to point small turbines, while large turbines make use of wind sensors, which is
