3. INTRODUCTION
• Renewable energy: Energy that is derived from natural process
that are replenished constantly
• Some Aspects of Renewable Energy
• it exists perpetually and in abundant in the environment
•
•
Ready to be harnessed, inexhaustible
it is clean alternative to fossil fuel

4. • Present Installed Capacity of Renewable
Energy Sources in India

5. WIND ENERGY
•
•
•
Differential heating of the earth’s surface
and atmosphere induces vertical and
horizontal air currents that are affected by
the earth’s rotation and contours of the
land and generates WIND.
A wind turbine obtains its power input by
converting the force of the wind into a
torque (turning force) acting on the rotor
blades.
The amount of energy which the wind
transfers to the rotor depends on the
density of the air, the Blade area, and
the wind speed.
P  Power
P = 0.5 X ρ X A X V3
ρ  Air Density (kg/m3)
A  Blade Area -turbine (m2)
V  Wind velocity (m/s)

6. TYPES OF WIND TURBINES

7. Major components of wind turbine

8. PROS…OF WIND ENERGY
• Wind is free, and the power it
generates has been harnessed for
centuries
• Generation and maintenance cost
of turbines have decreased
significantly in recent years
• Wind power is well suited in rural
areas
• No water pollution
• No wastes

9. CONS… OF WIND ENERGY
• Transmission – How to get energy
from point A to B
• Technology – means storage and
containments must be developed
• Noise and view disruption becomes
an issue with communities near
wind farms
• Endangered birds can be killed by
flying too close to wind turbine

10. CONCLUSION
• Wind energy is Eco-friendly renewable resource and it
causes no Harm to Environment.
• It is clean alternative to fossil fuel
