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

7. THIS IS MY PROJECT

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
