  • The power of the wind has been utilized for at least 3000 years. It is known that the Persians used vertical axis wind turbines during 700BC [1]. The earliest windmills had vertical axis. The first details about horizontal axis windmills are found in historical documents from Persia, Tibet and China from about 1000 AD. In Europe, windmill performance is continuously improved between the 12th and 19th centuries.
  • Wind energy is one of the most important and reliable energy sources among the renewable energy sources. Wind power generation has known a remarkably rapid growth in the past 20 years, and now it is a mature, reliable and efficient technology for electricity production.With increasing significance of environmental problems, clean energy generation becomes essential in every aspect of energy consumption. With government policies and incentives throughout the world supporting the rapid construction of renewable generation facilities, the renewable share of world generation increases from 18% in 2007 to 23% in 2035
  • it generates electricity, but does not release any harmful pollutants or gases as by products.Wind energy does not involve the use of any fossil fuels or non-renewable sources of energy .Wind is a never-ending resourceWind energy is also one of the cheapest forms of energy available today .Each MW of wind power development provides 3 jobs years of employment. Wind also benefits the economy by reducing "hidden costs" resulting from air pollution and health care.
  • Created by differences in air pressures.Flows from areas of high pressure to areas of low pressure.Near equator and pole surfaces winds are weak. Near surface winds occur by pressure gradients and these gradients cause to temperature gradients, which lead to strong winds

    2. 2. Historical background The power of the wind has been utilized for at least 3000 years. Sails were used to drive a mill stone For the grinding of grain. It is known that the Persians used vertical axis wind turbines during 700BC. The earliest windmills had vertical axis. In Europe, windmill performance is continuously improved between the 12th and 19th centuries.
    3. 3. Why wind Energy ? With increasing significance of environmental problems, clean energy generation becomes essential in every aspect of energy consumption. It is well known that wind energy is one of the cleanest and most environmentally friendly energy sources, and unlike fossil fuels, the wind will never be depleted. All forms of energy production have an environmental impact, but the impacts of wind energy are low, local, and manageable.
    4. 4. Pros of Wind Energy It is clean source of energy it is an efficient renewable energy Wind is a never-ending resource cheapest forms of energy Economic Benefits

    6. 6. Cons of Wind Energy  turbines can get damaged it does not eliminate electricity problems completely Noise the production of electricity depending upon the speed of the wind Bird and Mortality Location
    7. 7. Wind Created by differences in air pressures. Flows from areas of high pressure to areas of low pressure. Near equator and pole surfaces winds are weak. Near surface winds occur by pressure gradients and these gradients cause to temperature gradients, which lead to strong winds
