Why Wind Energy?
•
•
•
•
•
•
•
•
•
•
Most viable & largest renewable energy resource
Widely distributed & clean
Can get started with as small as 100-200 W
Produces no green house gas emissions
Low gestation period
No raw materials & fuels required
No pollution
No hassles of disposal of waste
Quick returns??
Good alternative for conventional power plants
Wind Energy - What is it?
• Wind is the natural movement of air across the
land or sea.
• Wind is caused by uneven heating and cooling of
the earth's surface and by the earth's rotation.
Land and water areas absorb and release
different amount of heat received from the sun.
As warm air rises, cooler air rushes in to take its
place, causing local winds.
• The rotation of the earth changes the direction
of the flow of air.
WIND RESOURCE-GLOBAL WIND SYSTEM
•
All renewable energy (except tidal and geothermal power), and
even the energy in fossil fuels, ultimately comes from the sun.
About 1–2% of the energy coming from the sun is converted into
wind energy
The region around equator at 0 deg latitude are heated
more by the sun than the rest of the globe. Due to this
flow of air takes place from the cold regions to hot regions.
WIND POWER - What is it?
Basic technology
• Wind
Electric
Generator
converts
kinetic
energy
available in wind to electrical
energy by using rotor, gearbox
and generator.
The Basic Process
• The wind turns the blades of a windmill-like
machine.
• The rotating blades turn the shaft to which
they are attached.
• The turning shaft typically can either power a
pump or turn a generator, which produces
electricity.
The Basic Process
• The amount of energy produced by a wind
machine depends upon
1.Wind speed and the size of the blades.
• In general, when the wind speed doubles, the
power produced increases eight times.
• As the diameter of the circle formed by the
blades doubles, the power increases four
times.
Wind Turbines: Number of Blades
Most common design is the three-bladed turbine.
+ Better stability.
A rotor with an odd number of rotor blades (and at least three
blades) can be considered to be similar to a disc when calculating
the dynamic properties of the machine.
A rotor with an even number of blades will give stability problems
for a machine with a stiff structure..

Wind Regime in India
• Wind climatology in India is influenced by the strong
monsoon circulations
• Wind speed during November to March is low, except in
Southern tip of Tamil Nadu
• Best Windy Sites are in Kerala, Karnataka, Tamil Nadu,
Gujarat, Andhra Pradesh and Maharashtra
