Are Wind Generators Worthy Of The Investment Or Are They Dangerous
Practically everyone is aware of what a wind turbine is and the way in which they produce energy, however for those who don't know I will explain. If you imagine a plane propeller sitting on top of a tall tower, this is what a turbine looks like.
Electricity is produced by the generator, housed in the turbine casing, whenever the rotor is turned by the wind. Inside the electrical generator are many magnets and lots of copper wire, which produces electricity. This process has been used for quite a while in some other forms of generators.
There must be sufficient wind to turn the blades for these power generators to generate electricity. The reason turbines are built so high is to take advantage of the stronger winds found at more significant altitudes. The result of the stronger wind at that level is that the turbines generate more electricity. Obviously there needs to be enough wind to make electricity from the get go. This is the reason why extensive research is done on areas for potential wind generators to ensure that there's enough wind to produce energy. This tends to mean they are situated along coastlines where it is ordinarily very windy. Of course, the wind can switch its direction which presents another downside for wind generators. A time tested design, adapted from the early wind powered water pumps, utilizes a tall fin to point the propeller directly into the wind, regardless of the direction it emanates from.
Enough electricity to meet the requirements of an entire household might be produced from a single turbine. When there's no wind, a battery backup installation is used to meet electrical needs. Because of the high initial investment, which will require decades to recover, wind generators require a long-term perspective. Unlike some other green energy methods, wind generators will consistently work 24/7, providing there's wind. Wind turbines will be able to produce as much electricity at night as during the day, decreasing the battery storage demands in some cases. With so much worry about pollution today, turbines are a great alternative because they are so clean. The conventional sources of hydro, including nuclear reactors, create tremendous pollution that could be eliminated by turbines. The energy source is additionally renewable, just like solar energy, since there is always wind blowing. There's no danger of turbines running out of propulsion.
As with nearly anything there are some down sides of implementing wind generators for energy. They're certainly not a pretty sight, especially because they're so massive. Large installations, with dozens, 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 observed is that birds and bats (bats especially) often fly into them. The reason stated for bats flying into wind generators is that the activity in the air disrupts their capability to hear and see with sonar. This does not happen often, but whenever it does, it is sad.
Thinking about the advantages and disadvantages of wind generators, they have a lot going in their favor. They can play a primary role in our long term energy plans if they are applied carefully.
