Wind Powered Turbines, The Positive Aspects And Disadvantages
Article by Claudia Jordan
Practically everybody knows what a wind turbine is and the way in which they produce energy, but for those which don't know I will explain. If you picture a plane propeller sitting atop a tall tower, this is what a turbine looks like. As the big propeller is spun by the breeze, the rotor inside moves to produce electricity. The generator is a general design consisting of magnets and copper cables. It is a rather simple technique.
Clearly for the turbine to do the job there will have to be wind. The average height for wind turbines is actually 30 meters, which allows them to utilize the more powerful winds that occur at that height. This height enables the rotor to obtain more exposure to the wind and subsequently create a lot more electricity. All of this would not matter if there was no wind from the beginning. Before an installation of turbines is designed, thorough analysis of wind patterns for the planned site is reviewed. This tends to mean they are located along coastlines where it is generally very windy. Of course, the wind can adjust its direction which poses another downside for wind turbines. A time tested layout, adapted from the initial wind powered water pumps, makes use of a tall fin to point the propeller into the wind, regardless of the direction it originates from.
Enough electricity to meet the requirements of an entire household might be produced from a solitary turbine. You can also stow the electricity into batteries to use when there is no wind. While they can certainly produce a lot of electricity, they're not cheap at all and getting back your introductory investment on one can take many years. Unlike various other green energy methods, wind turbines will consistently work 24/7, providing that there is wind. In areas that experience many hours of darkness during some periods, turbines may be a better green solution compared to solar panels. Another good thing about wind turbines is that these are generally eco-friendly as they produce zero pollution. This suggests that wind turbines do not contribute to the effects of global warming due to the fact there are no fuels actually burned and no emissions being discharged into the atmosphere. Harnessing the power of the wind is making use of a truly green resource. This indicates that turbines will always be able to produce energy if they are located in high wind areas.
Even though they have got a lot going for them, there are some negative aspects to consider. Many people don't want to be looking at a tall tower with a propeller at the top outside their window. Large installations, with a good deal, or even hundreds grouped together, produce visual pollution in coastal areas, according to critics. They are also very noisy due to the rotor generating sound as it rotates. Another major issue that people have mentioned is that birds and bats (bats especially) have a tendency to fly into them. The justification stated for bats flying into wind turbines is that the movement in the air disrupts their proficiency to hear and see with sonar. There are no data on how often this happens, however.
The overall positive aspects of wind turbines seem to outweigh the disadvantages at the moment. They can play a significant role in our upcoming energy plans if they are utilized carefully.
