Wind is a natural source of energy. This energy can be harnessed using windmills.
How does wind energy work
A windmill can produce a very small amount of electricity, so a large number of windmills are arranged in order to produce enough electricity for our use. This area is called a wind power farm.
Structure of a Windmill
a windmill is like a large electric fan, which is erected on a rigid base. The kinetic energy of the wind moves the blades of the windmill. This causes the axis of the electric generator to rotate. Which leads to the generation of electricity.
This power is then passed to the transformer. Transformer transfers electrical energy from one circuit to another at the required voltage.
Finally the electricity is sent to the grids. from where it is distributed for domestic and commercial uses.
Wind energy advantages and disadvantages
Wind power is a pollution free source. There is no need to spend for this again and again. For resources such as coal etc. Because it is freely available as a source of energy. Windmills can be installed wherever a sufficient amount of wind blows.
To generate electricity, the minimum wind speed should be 15 kilometers per hour.
Wind power farms can be very costly to build. When the wind is not blowing, you have to arrange for an alternative system to meet the energy requirements.
