This document provides information about wind energy and windmills. It introduces the topic of wind energy, discussing the history of wind power generation dating back to 1887. It also notes that India has the 4th largest installed wind power capacity in the world. The document then covers the causes of wind, including uneven heating and the Coriolis effect. It lists some uses of wind energy such as electricity generation and transportation. Both the advantages and disadvantages of wind power are presented. Finally, the document describes windmills and their uses for pumping water and grinding.

- 2. INTRODUCTION • Air in motion is called wind I.e A moving mass of air is called wind . The winds on earth surface are called primari by the unequal heating of the land and water by the sun . • The difference in temperature gradient include the circulation of the air from one zone to another . • Energy derived from wind velocity is wind energy. • Utilizing the wind is not a new technology. For thousands of years the humans have used the power in the wind to ease the everyday life, in household, farming and industry.
- 3. HISTORY OF WIND ENERGY • The first attempt at large-scale wind generation of electricity is attributed to Charles Brush in 1887, Ohio, USA. ... • In 1941, the world’s first megawatt-sized wind turbine, the Smith-Putman wind turbine, was built and connected to the local electrical distribution system in a mountain in Castleton, Vermont,USA • India has the 4th largest installed capacity in wind power after China, U.S and Germany. • The total installed capacity of wind power in India as on March 2017 is around 32 GW. A recent study by National Institute of Wind Energy (NIWE) has shown wind energy potential of 302 GW at 100 m hub-height in India.
- 4. CAUSES OF WIND BLOW • The three factors responsible for blowing of wind are:- • (1) The uneven heating of equatorial region and polar regions of energy by sun- rays.
- 5. • Rotation of earth :- Generally, prevailing winds blow east-west rather than north- south. This happens because Earth’s rotation generates what is known as the Coriolis effect. • The Coriolis effect makes wind systems twist counter-clockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere.
- 6. USE OF WIND ENERGY • To generate electricity... • In Transportation...... • For Wind Sports..... • In Food Production...... • For Pumping Water......
- 7. ADVANTAGE OF WIND ENERGY • Wind power is cost-effective. ... • Wind creates jobs. ... • Wind enables U.S. Industry growth and U.S. Competitiveness. ... • It’s a clean fuel source. ... • Wind is a domestic source of energy. ... • It’s sustainable. ... • Wind turbines can be built on existing farms or ranches.
- 8. DISADVANTAGED OF WIND ENERGY • The wind is inconsistent. ... • Wind turbines involve high upfront capital investment. ... • Wind turbines have a visual impact. ... • May reduce the local bird population. ... • Wind turbines are prone to noise disturbances. ... • Installation can take up a significant portion of land. ... • Wind turbines can be a safety hazard.
- 9. WIND MILL • Windmill, device for tapping the energy of the wind by means of sails mounted on a rotating shaft. ... • The sails are mounted at an angle or are given a slight twist so that the force of wind against them is divided into two components, one of which, in the plane of the sails, imparts rotation.
- 11. WINDMILL FOR PUMPING WATER • A water-pumping windmill pumps water from wells, ponds, and bore wells for drinking, minor irrigation, salt farming, fish farming, etc. • Available windmills are of two types, namely direct drive and gear type.
