Are Wind Turbines Good Or Simply Harmful?
Article by Matt Holmes
Changing wind power into electricity is normally the function of wind turbines. A regular wind turbine is a large tower that has blades connected to a rotor. Electricity is created by the generator, housed inside the turbine casing, any time the rotor is turned by the wind. The generator is a general design made up of magnets and copper wires. There’s almost nothing complicated about this type of generator.
Obviously for the turbine to do the job there must be wind. Wind is much more powerful higher up in the sky, which is why wind turbines are relatively tall, at around 30 meters. The end result of the stronger wind at that height is that the turbines produce more electricity. Of course it’s understandable that without sufficient wind, no power will be generated. This is the reason why extensive research is done on areas for potential wind turbines to make certain that there’s enough wind to produce energy. Many coastal places are ideal thanks to steady high winds. Consistent winds does not necessarily mean that they consistently blow from the same direction. To adapt to varying wind directions, the turbines are made to continually face into the wind, irrespective of direction.
Enough electricity to meet the needs of an entire household can be produced from a single turbine. When there’s no wind, a battery backup assembly is used to fulfill electrical needs. While they can certainly produce a lot of electricity, they are not cheap at all and getting back your initial investment on one may take many years. Unlike some other green energy methods, wind turbines will continue to work 24/7, providing there’s wind. In locations that experience many hours of darkness during some seasons, turbines may be a better green solution than solar panels. With so much fear about pollution these days, turbines are a great option because they are so clean. The conventional sources of hydro, including nuclear reactors, create incredible pollution that could be reduced by turbines. The energy source is additionally renewable, just like solar energy, because there is always wind blowing. There is certainly no danger of turbines not having enough propulsion.
As with anything there are some disadvantages of implementing wind turbines for energy. Their size makes them stand out, and some say they’re ugly for this reason. When grouped in groups, such as the large commercial installations in coastal areas and even out at sea, where there are high winds, they are certainly not an attractive site. They are also quite noisy due to the rotor producing sound as it goes. Another major concern that people have noted is that birds and bats (bats especially) have a tendency to fly into them. The reason stated for bats soaring into wind turbines is that the activity in the air disrupts their ability to hear and see with sonar. This doesn’t happen often, but any time it does, it is regrettable.
Thinking about the advantages and disadvantages of wind turbines, they have a lot going in their favor. Wind turbines offer great promise for generating clean, sustainable and safe energy, with handful of serious downsides.
