4. 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.
5. 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.
6. 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
8. 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
9. 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
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 The first details about horizontal axis windmills are found in historical documents from Persia, Tibet and China from about 1000 AD.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.
