As the wind blows, large blades spinning at the top of a tower, connects to a generator that converts the energy to
produce electricity. Wind power is a relatively efficient form of generation as it can convert 40% of its energy
into electricity.
The turbine blades are designed to track the wind as it changes its direction in order to capture the maximum amount
of wind. If the wind speed becomes excessively high, the turbine shuts down to avoid danger.
Wind energy is a clean source of fuel that emits very little carbon dioxide (CO
2, the leading greenhouse
gas associated with global climate changes). A wind farm does not produce SOx or NOx because it does not
rely on combustion of fossil fuel. Since the effectuation of Kyoto protocol, wind energy has been attracting
growing attention and further research & development is expected.
