What is wind energy

Wind energy is the kinetic energy of the wind. This kinetic energy can be captured and converted to more useful forms of energy like mechanical energy or electrical energy. Wind energy finds many uses both for domestic as well as commercial purposes. Wind energy does not use any fuels and does not emit any harmful or greenhouse gases into the atmosphere. It is, therefore, an environment friendly form of energy.

The amount of energy in the wind depends upon the speed of the wind, air temperature, barometric pressure and Altitude.

Generally, the amount of wind energy is more at high altitudes and when the pressure is low. The more the speed of the wind, the more energy it possesses.

The cost of wind energy depends upon the initial cost of wind turbine installation and the amount of energy produced.

Usually the cost of installing a wind turbine is a lot. Wind turbines as equipments are very expensive. However, if the amount of energy produced by wind turbines is more, the costs of installation are overshadowed by the benefits of the electricity so produced.

With the use of better technologies, the wind turbine installation costs are decreasing and generating electricity by wind energy has now become a cost effective method for the same.

The use of wind energy is increasing all over the world. The main reason for this is that wind energy has several environmental, social and economic advantages. Because of these advantages, wind energy can be favorably used.
