Understanding What is Wind Energy What Is Wind Energy. The
definition of wind energy is the energy which we harness from
wind current in the atmosphere. Wind turbines capture the
kinetic energy of the wind and convert into useful electrical
and mechanical energy. The wind happened because of the
different of pressure. In the atmosphere, there is always high
pressure and low pressure areas. When both of areas come close
to each other, the air flows from the high pressure area to low
pressure area. The knowledgeable sailors have been use wind
energy for many years. The wind power will push the boat along,
when the sail is lifted. Otherwise the boat will stop moving
forward when they lower the sail. The change direction of sail
can used to steer the boat. Wind turbine is basically a
generator, this machine has aerodynamics blades which are
rotated by the wind incident on them. Then the energy is
transferred into transmission box. It causes a high speed shaft
to turn a generator and then produce electricity. The
