Wind turbine is basically a big windmill, with large blades that change the air and converting the power generated from wind. Turbines are made of metal plastic, aluminum, steel and the other from the space age.
Wind turbines have a negative impact on the environment. They are very visible, very ugly and should be placed close to the ground, efforts to find an open field or beach will be met with great success. They require a lot of energy in its manufacture, usually from fossil energy, and therefore can take a considerable amount of time before they were positive in terms of total carbon emissions over time can vary from 2 to 5 years. Wind turbines need to be assessed for the impact on wildlife as birds can be mutilated as it passes through the turbine fans that circulate in this section.
With all the weaknesses, in addition to wind turbines should be an option when it comes to a comprehensive plan for renewable alternative energy. Once built, wind turbines is great both in a wider sense - which generate electricity from natural products, eco-renewable resources, without social or environmental penalty is hidden must be spent in the use of fossil fuels - there is no need to extract the fuel or transport - there is no global warming pollutants created, and no need to store, process or eliminate toxic waste.
Turbine size is small; the turbine can be as small as 5 meters in diameter and only a few hundred watts capacity. At the upper end of the spectrum, the turbine can be as large as 300 meters in diameter and capable of producing two to five megawatts of electricity.
Similar to solar photovoltaic power plant, there may be discounts available for construction, and the excess energy can be sold to utilities.
Wind speed is influenced by topography and increased ground clearance, so wind turbines usually installed on top of the tower. In typical applications, a wind turbine at the top of the tower height and produces a low voltage direct current used to charge batteries at the store - a store of potential energy is fully utilized by routing through an inverter that converts alternating current to low voltage direct current voltage electricity that can be used in domestic applications.
Concentrating a lot of wind turbines in a field means large amounts of electricity can be stored and used, perhaps for the entire town or city.
Because the wind does not blow all the time in the region wind turbines are used in conjuction with hybrid configurations with different technologies such as solar panels and diesel generators to provide constant power source.
Unlike fossil fuels from the station, wind turbines are clean and green - do not create carbon dioxide emissions that cause greenhouse gases and SO2 emissions that cause acid rain.
Turbines are now divided into two categories, such as vertical and horizontal wind turbines. The horizontal axis is actually getting better now that the wind turbine vertical axis wind is always the same amount of area swept (the diameter of the circle traced by the end of the propeller).
