Wind energy is considered by many as an emerging technology, the truth of the matter is that we have been using wind power for many hundreds of years for grinding grain and for milking our cattle up. With the dawn of the industrial revolution the use of wind to power machinery fell by the wayside in the form steam and eventually electricity grew in popularity.
Recent environmental concerns have made way for the return of wind power and in its wake came a series of myths, falsehoods and misunderstandings. This article aims to dispel some common myths of wind power.
Wind turbines are only effective in high winds
This is a common misconception regarding wind turbines. Obviously, the more wind is not more electricity each wind turbine will generate, but even a slight breeze large commercial wind turbines and smaller residential wind turbines will generate an acceptable amount of electricity. A change of wind speed, the angle of the turbine blades to be adjusted accordingly maximum efficiency, regardless of wind speed.
Wind turbines are noisy
This may have been true in the past as many early wind turbines did not have guidelines to adhere to noise emission. Furthermore, wind turbine manufacturers and companies Wind power does not really consider the impact of a large-scale wind farm could have on nearby residential areas. These first turbines are the source of current wind turbines are noisy "myth. In the last ten years, wind turbine technology has advanced significantly, making mechanical noise almost undetectable.
Wind farm planners have to meet strict guidelines to protect residential areas close to the noise emissions. This not mean that wind farms are quiet and there is an audible Swoosh 'like the turbine blades passing the tower, however, this only listens a relatively narrow range.
Wind farms are not profitable
Twenty thirty years ago, wind farms and technology wind turbine was the victim of trial and error, to some extent. Windfarms not confuse older, noisier and more expensive with their modern counterparts. At the beginning of 1980 more than 5000 wind turbines were launched in the Tehachapi Pass in California. These days the wind farms consist of less turbines largest wind have proven to be not only more cost effective, but more appealing to the view that early wind farms dotting the landscape with hundreds small wind turbines.
Home wind turbines are a waste of time and money
The turbines smaller wind origin are more often than not used in combination with a series of solar panels. The wind turbine will continue to charge the batteries overnight, even in a slight breeze that means a steady trickle of electricity is potentially available 24 hours a day. Prices of home wind turbines vary depending on the output power and the cost of installation. A small wind turbine reduce residential electricity bill averaged around 20-35%. Or, to put it another way, a residential wind turbine would save around half a tonne of CO2 each year.
Wind farms kill birds
It is true that a considerable number of birds have flown in wind turbine blades, and as a result have been wounded or even killed. To say that it is also true that a large number of birds die each year as a result of flying into tall buildings or are hit by cars, trains, trucks and buses. It is unfortunate that human impact on the environment has its toll on wildlife, to some extent, however, wind farm poses no significant threat to birds or any other form of wildlife.
