Almost everybody is familiar with what a wind turbine is and the way they produce energy, however for those whom don't know I will explain. The traditional design resembles a small windmill on a toll structure. Any time the wind blows the wind turbine the blades make the rotor spin and the movement of the rotor forces the generator within the turbine generate power. As with most types of power generators, magnets as well as copper wires are arranged to create a charge any time the rotor spins. This system has been utilized for many years in some other types of generators.
There must be sufficient wind to rotate the blades for these power generators to create electricity. The average height for wind turbines is actually 30 meters, which enables them to utilize the more powerful winds that happen at that height. The result of the stronger wind at that level is that the turbines produce more electricity. Of course it goes without saying that without sufficient wind, no power will be produced. Historical weather data is carefully analyzed to select sites that will provide sufficient continuous winds for the turbines. One excellent location is in coastal areas because there are usually consistent wind patterns in these places. Although wind speed is the most important variable to measure, wind direction will also have an impact on the performance of the installation. Nevertheless the design is extremely clever and they are manufactured so that the rotor turns in the direction of the wind, enabling them to pick up the wind from any direction.
Because of their economical design, turbines can create a lot of power that can be implemented for domestic or industrial applications. A battery backup that's replenished by the turbines, supplies power during instances when no wind blows. One concern is the number of years required for the installation charges to be recovered in power savings. Unlike other green energy methods, wind turbines will consistently work 24/7, providing there is wind. Solar panels cannot operate in the dark while wind turbines can. With so much fear about pollution today, turbines are a great option because they are so clean. More turbines may reduce the causes of global warming which in turn threaten the planet today. Another feature is that turbines are using energy from a continuously renewing source. Therefore there is always going to be energy produced by the turbines.
As with anything there are some disadvantages of implementing wind turbines for energy. Many people don't want to be observing a tall tower with a propeller on the top outside their window. When put in groups, such as the massive commercial installations in coastal regions and even out at sea, precisely where there are high winds, they are not an attractive site. They are also fairly noisy due to the rotor creating sound as it moves. While excellent for meeting the needs of human beings, they can be harmful to birds and bats. Bats particularly are susceptible, due to the fact their sonar system is disturbed by the rapid movement in the air. While these incidents are rarely noted they do take place.
Wind turbines definitely seem to be a great source of energy, but of course there are downsides like with anything. With suitable planning they can be very useful and beneficial.
