Are Wind Generators Economical?


We Ask “Are Wind Generators Economical?”

Transforming wind power into electricity is actually the function of wind turbines. If you envision a plane propeller sitting on top of a tall tower, this is exactly what a turbine looks like. As the giant propeller is spun by the wind, the rotor inside moves to create electricity. Inside the power generator are many magnets and loads of copper wire, which creates electricity. This method has been used for quite some time in some other kinds of generators.

There has to be sufficient wind to rotate the blades for these generators to create electricity. The reason why turbines are built so extremely high is to take advantage of the stronger winds found at higher altitudes. The end result of the stronger wind at that level is that the turbines produce more electricity. All of this would not matter if there was actually no wind in the first place. Just before an installation of turbines is engineered, thorough analysis of wind patterns for the projected site is reviewed. One excellent location is in coastal zones because there are usually consistent wind patterns in these areas. Consistent winds does not always mean that they consistently blow from the same direction. To adjust to varying wind directions, the turbines are designed to continually face into the wind, irrespective of direction.

Wind generators can produce quite a lot of energy; one turbine may generate electricity for one house, or they can be used to power machinery which in turn does something like grinding feed. You can also stow the electricity into batteries for when there is no wind. One concern is the number of years necessary for the installation costs to be recovered in power savings. In areas with constant winds, turbines can easily produce energy around the clock. In places that experience quite a few hours of darkness during some seasons, turbines may be a far better green solution as compared to solar panels. Turbines are extremely clean to run, reducing concerns about pollution. The conventional sources of hydro, which includes nuclear reactors, create tremendous pollution that could be eliminated by turbines. Another advantage is that turbines are using energy from a constantly renewing source. Therefore there is always going to be energy generated by the turbines.

As with nearly anything there are some down sides of using wind turbines for energy. Many people don’t want to be viewing a tall tower with a propeller on the top outside their window. Large installations, with dozens, or even hundreds grouped together, produce visual pollution in coastal areas, as outlined by critics. Like any mechanical device that moves, they may be quite loud. Wildlife fanatics complain that birds and bats are damaged by them. Bats particularly are susceptible, simply because their sonar system is interrupted by the rapid motion in the air. While these occurrences are rarely documented they do happen.

Thinking about the benefits and drawbacks of wind generators, they have got a lot going in their favor. With appropriate planning they can be very useful and productive.
