Historical background

The power of the wind has been utilized for at least 3000 years.Sails were used to drive a mill stoneFor 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.

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.

Wind

Created by differencesin 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
