Wind Energy is the energy imparted due to motion of air. Wind energy can be utilized in various ways to get power. It is non conventional and greener way to get power. Wind is motion of air. Due to heat of Sun, a place on Earth gets heated. Air becomes less dense in that region. Air from denser region starts to move to that low density region. This create motion of air known as Wind. It is function of density and heat. Wind energy is being used from years for various purposes like drying cloths, grains, etc. Later, we started to use it for pumping water from well and grinding grains. It is possible to get power for our daily requirement from the wind. Wind Mill is a device which converts wind energy into electrical energy. It is installed in hilly areas where wind is always available. Wind impacts on the blades of wind mill. They start to rotate. A generator, through gear transmission is connected to the blades As generator rotates, electric energy is obtained. Today, we have many places where energy is 100% obtained from Wind only. Wind energy, however has disadvantage of discontinuity. Wind Energy also cause Waves in oceans. These waves can be also used to generate electricity. Prototype projects for the same are being operated in some areas. Some plants use combined energy from Wind Mill and Solar Cells which has higher output and efficiency. Small Wind Mill can be installed at home, which can generate enough electricity to power up a room. It would also decorate the view of home. Wind Energy is the God’s gift to us to obtain green energy forever. |
