Wind Power for a Better Tomorrow

Wind energy is the energy contained in the force of the winds blowing across the earths surface.When harnessed, wind energy can be converted into mechanical energy for performing work such as pumping water, grinding grain by wind mills and producing electrical energy, by wind turbines.The circulation of air in the atmosphere is caused by the non uniform heating of the earth’s surface by the sun. The air immediately above a warm area expands and becomes less dense. It is then forced upwards by a cool denser air which flows in the surrounding areas causing a wind. Wind energy is a popular form of non-conventional energy. It is utilized for drawing water, which is an essential requirement in watering agricultural lands in the rural areas. In addition, it can be utilized for electricity generation. In India, states like Tamil Nadu, Gujarat, Orissa, and Maharashtra are regarded as superior areas with respect to this type of energy. Places that have regular and rapid wind flows are appropriate for this kind of power generation. Other than windmills, wind farms are there as well. Wind power is the conversion of wind energy into a useful form of energy, such as using wind turbines to make electrical power, windmills for mechanical power, wind pumps for water pumping or drainage, or sails to propel ships. Large wind farms consist of hundreds of individual wind turbines which are connected to the electric power transmission network. Offshore wind is steadier and stronger than on land, and offshore farms have less visual impact, but construction and maintenance costs are considerably higher. Small onshore wind farms provide electricity to isolated locations. Utility companies increasingly buy surplus electricity produced by small domestic wind turbines.[1] Wind power, as an alternative to fossil fuels, is plentiful, renewable, widely distributed, clean, produces no
