Wind generators are regarded as one of the most reliable forms of renewable power sources on the planet that are now available. They generate electric power by converting the kinetic energy of the blowing wind into mechanical energy, which is then either utilized directly (i.e. in the case of windmills which are used to produce flour from wheat) or coupled to a generator which produces electrical energy that could be later used. With that being said, the type of wind generators which produce electric power is of more interest to us, since this power can be utilized for a great variety of purposes.

This energy could be used for both residential and commercial power needs. As a result, wind turbine manufacturers offer wind turbines for the home in addition to their industrial equivalents.

Wind turbines are basically huge windmills, with gigantic blades which rotate in the blowing wind and create power from the transformation of the winds force. They are manufactured from steel, plastic, aluminum and many other modern metals. Despite their myriad benefits, wind generators have a few adverse impacts on the environment. First off, they are very visible, and quite unsightly since they must be placed in proximity to breezy, open landscape to be useful - attempts to place them off the coast have been met with great success.

Regarding size, wind turbines could be as small as five feet in diameter and can handle only a few hundred watts, and also huge as three hundred feet in diameter and are capable of generating two to five megawatts of electrical power.

Once put up, wind turbines are extremely useful - they produce clean energy from a natural, eco-friendly renewable resource, without the hidden social or environmental penalties which we incur with the use of fossil fuels - there is no need to mine for fuel or to transport it - there aren't any global warming pollutants created, and no need to store, process, or to dispose of toxic waste materials.

Another advantage to the economy is that this relatively new industry is creating work opportunities: wind turbine jobs, roles that need installation, supervision and maintenance of wind turbines are expected to increase.

However, yet another downside is that wind generators need a great deal of energy in their manufacture, energy that is usually fossil-based, and therefore it will take a lot of time before they are positive in terms of total carbon emissions - this time could be anywhere from two to five years.

Wind velocity is afflicted by topography and increases with height above the ground, so wind generators are generally installed on top of big towers. In a typical application, the wind generator is placed on top of a large tower and creates low voltage current which is used to charge a battery store - this stored potential energy is eventually utilized by routing it through an inverter which transforms the low voltage direct current power into utility voltage alternating current electrical energy that could be used in household applications.

By concentrating plenty of generators into wind farms a substantial amount of electrical energy could be stored and employed, potentially even for an entire city. Since the wind does not blow all the time in many areas (this depends upon local geography), wind turbines are utilized along with a number of technologies such as solar panels, and diesel generators to produce a consistent source of electrical power. In conclusion, wind generators are clean and eco-friendly. They do not produce the carbon dioxide emissions which cause greenhouse gases or the SO2 emissions that cause acid rain.
