Wind Energy As A Source Of Electricity


The importance of a reliable source of electricity is a necessity that most people who live on isolated areas consider a privilege, among other vital basic needs on the list. Areas marginally isolated from the main power grid require independent sources of energy for sustenance and basic day to day life operations. Luckily, wind is a natural resource and a gift to mankind from nature. Almost anyone around the globe can experience the benefits of wind energy, but it takes investment in a good wind turbine. Although it demands constant maintenance and attention, wind turbines are capable of generating thousands of volts enough to supply a community that shares a common grid.

Throughout history, man has been using the wind turbine foe electricity generation for quite a number of purposes. Apart from domestic utility, the energy derived from the wind has also been used for various commercial applications especially in the Scandinavian countries. Regions with vast, wide spaces utilize the privilege to operate multimillion commercial endeavors successfully. For instance, Germany owes much of its electricity supply to wind energy. A common utility grid connects residential and industrial energy consumers contributing hugely to the nation’s Gross Domestic Product.

For domestic purposes, the investment in wind energy need not be extensive. A good motor is required for steady rotation, quality strong blades and an alternator. The basic concept in the wind turbine is maintaining a constant kinetic energy around a shaft. The alternator converts the energy into electric energy which can then be stored via a transformer or cellular battery. An average turbine is capable of producing over fifteen kilowatts of electricity. Although the wind is not always constant, larger output turbines have a gearbox installed for the purposes of increasing the alternator speed in rotor turns slowly.
In order to track the wind direction and aptly capture the wind, turbine blades should always face the wind. A yaw bearing is usually installed to track the wind direction, while a tail attacked at the rear aids direction of the rotor toward the wind. Wind turbines must be fitted with a switch off mechanism in cases of extreme weather or servicing.
