Are Wind Turbines Good Or Risky?
Article by Eva Rose
Changing wind power into electricity is actually the purpose of wind turbines. The standard design resembles a miniature windmill on a toll system. Electricity is made by the generator, housed in the turbine casing, when the rotor is spun by the wind. The generator is a common design composed of magnets and copper wires. This process has been used for many years in various other types of generators.
Wind turbines, as the name suggests, necessitates wind to function. Wind is much more powerful higher up in the sky, which is why wind turbines are relatively tall, at around 30 meters. The consequence of the stronger wind at that elevation is that the turbines yield more electricity. Obviously there should be enough wind to generate electricity in the first place. Just before an installation of turbines is built, comprehensive analysis of wind patterns for the projected site is reviewed. Many coastal locations are ideal because of consistent high winds. Consistent winds does not mean that they always blow from the same exact direction. To conform to varying wind directions, the turbines are made to continually face into the wind, irregardless of direction.
Wind turbines can create quite a lot of energy; one turbine may generate electricity for one house, or they can be used to power machinery which does something like grinding wheat. A battery backup that is replenished by the turbines, delivers power during instances when no wind blows. One concern is the number of years necessary for the installation expenses to be recovered in power savings. Unlike some other green energy methods, wind turbines will always work 24/7, providing there’s wind. In locations that experience many hours of darkness during some periods, turbines may be a better green solution compared to solar panels. With so much fear about pollution nowadays, turbines are a great solution because they are so clean. The conventional sources of hydro, such as nuclear reactors, create tremendous pollution that could be reduced by turbines. Another feature is that turbines are capturing energy from a continuously renewing source. This indicates that turbines will always be able to produce power if they are located in high wind areas.
Let’s consider just what some may illustrate as the cons of wind turbine produced electricity. They’re unquestionably not a pretty sight, particularly because they’re so large. When clustered in groups, such as the large commercial installations in coastal regions and even out at sea, precisely where there are high winds, they are not really an attractive site. They are also fairly noisy due to the rotor producing sound as it goes. Another major issue that people have noted is that birds and bats (bats especially) often fly into them. The reason stated for bats soaring into wind turbines is that the motion in the air disrupts their ability to hear and see with sonar. There are no statistics on how often this happens, however.
The overall positive aspects of wind turbines seem to over-shadow the disadvantages at the moment. With appropriate planning they can be incredibly useful and effective.
