3. Principle of
Wind Energy
1. The energy in the wind
turns two or three
propeller-like blades
around a rotor. The rotor is
connected to the main
shaft, which spins a
generator to create
electricity
2. Wind turbines convert
electrical energy to
Mechanical energy.

4. Types of Wind Turbines
VERTICAL AXIS HORIZONTAL AXIS

5. VERTICAL TURBINE
Rotating axis of wind
turbine perpendicular
to ground
Used for small wind
projects and residential
application
Power generation
efficiency 50-60%
Easy Maintenance
HORIZONTAL TURBINE
1. Rotating axis of wind turbine
parallel to ground
2. Used for large wind
application
3. Power generation efficiency
above 70%
4. Complicated Maintenance

6. Working of wind turbine

8. Advantages of wind Energy
1. Clean and renewable source of power
2. Cost effective
3. Rapid growth of industry, large potential
4. Wind is a domestic source of energy
5. Wind turbine can be built on existing farm

9. Limitations of
wind Energy
1. Wind turbines can affects
local wild life
2. Wind energy can make
noise pollution
3. It involves high upfront
capital investment
4. Wind turbines can be a
safety Hazzard

10. Future Scope
Future of wind energy can be
bright if government policies
subsidize and encourage its use.
Technology improvements
unlikely to have a major impact.
Can become cost competitive
for electricity generation if
fossil energy costs skyrocket.
