Wind power can be harnessed by huge rotating wind turbines that convert the kinetic energy in wind into mechanical energy, which in turn is converted into electricity.
The world’s largest turbines are over 198 m (650 ft) high and can deliver up to 6 MW.
Advantages
Wind turbines consume no fuel, and emit no air pollution unlike fossil fuel power sources.
The energy consumed to manufacture and transport the materials used to build a wind power plant is equal to the new energy produced by the plant within a few months of operation.
Disadvantages
Wind power is an intermittent power source. The power production from a wind turbine may increase or decrease dramatically over a short period of time with little or no warning. In the absence of large scale energy storage, or extra geographically dispersed turbines, the balance of the grid must be able to quickly compensate for this change.
Some people object to their aesthetic appearance and say they are a blight on the landscape.
