WHAT IS WIND ENERGY?
Wind energy is the energy that is produced by the wind flows
which is then converted to produce electricity. It is a
renewable energy that is plentiful around us and nondepleting as well. Its abundance in the nature makes it ranks
as one of the best resource for electricity. The wind energy is
captured with the wind turbines that help the wind energy to
convert it to mechanical and electrical energy.
The main aim behind bringing up wind farms is that wind
energy becomes the major producer of electricity. Thus,
more and more developments are happening around the
World to present it with the most modern techniques.

What are wind turbines and
how it works?
Wind turbine is the device which is used to generate
electricity from the power of wind. It looks like an airplane
propeller or like a fan that rotates according to the wind.
The turbine blades spin as the wind blows and thereby
making the shaft connected to the gearbox also spin. This
energy is then sent to the generator to produce
electricity.
The length of the blades have a major role is creating
more electrical energy. Depending on the technology
and wind speed rate, the blades of the turbine rotates up
to 20 times per minute. The life of a turbine is normally
calculated on an average of 20 years.

Advantages
Air as fuel is free and inexhaustible.
It is clean source of energy and does not pollute the environment.
The cost of electricity is too low and the wind turbine could be used over more than 20 years
It’s cheap as only the installation and maintenance cost is required.
Wind energy is one of the fastest-growing sectors all around the globe so it is generating a lot of
employment in manufacturing, installation and maintenance.

Disadvantages
It takes a lot of research and effort to decide the location where wind power plant has to
be installed, due to fluctuating pattern of wind.
Its initial setup cost is too high as to setup a turbine you have to go through a survey to
determine the wind speed of the location. It all adds up to the cost.
They are the greatest disadvantage to local bird population as they die due to collision
with blades.
Noise pollution is the one of the major disadvantage.
Wind power plant is only useful to the countries with coastal or hilly areas.
