The document discusses wind power as a renewable energy source. It describes how wind turbines convert kinetic energy from wind into electrical energy. Global wind power capacity has grown significantly in recent decades, led by China, the US, Germany, and India. The document outlines the various components of wind turbines and how they work. It also discusses the environmental benefits of wind power as well as some disadvantages, and notes that wind energy production is growing rapidly and having a positive economic impact through new jobs.

3. Introduction: Renewable energy!
Renewable energy is derived from natural processes that
are replenished constantly.
1. Solar, 2. Wind, 3. Hydropower, 4.
Biomass,5.Geothermal, 6. Wave, 7. Tidal
 All renewable energy (except tidal and geothermal power),
ultimately comes from the sun.
Renewable energy replaces conventional fuels in four
distinct areas: electricity generation, hot water/space
heating, motor fuels, and rural energy services.
Renewable energy resources exist over wide geographical
areas, in contrast to other energy sources.

5. Wind power- What is it?
Wind power is an alternative
energy source that is used
without producing by-
products that are harmful to
the environment.
Wind turbines create
electricity by using the wind, a
safe and renewable resources.
Wind turbines are helping our
economy and environment.

6. Why wind power?
Wind energy is the
fastest growing
renewable energy
source in the world.
The world wide
installed capacity is
growing at a rapid
pace of over 30% per
year.

7. How does it
work?
 Wind turbines are used
to generate electricity
from the wind.
 The wind turns the large
blades and the blades
turns a generator.
 Wind turbines convert
the kinetic energy of the
wind into mechanical
energy first and then into
electricity.
 Special designing of the
blades that is responsible
for the conversion.

8. Wind turbine components:-

9. Types of Electricity Generating Windmills:-
Small (10 kW)
• Homes
• Farms
• Remote Applications
(e.g. water pumping,
telecom sites,
icemaking)
Large (250 kW - 2+MW)
• Central Station Wind Farms
• Distributed Power
Intermediate
(10-250 kW)
• Village Power
• Hybrid Systems
• Distributed Power

10. Development:-
 The first windmill used
for the production of
electricity was built in
Scotland in 1887 by Prof.
James Blyth of Anderson’s
college, Glasgow.
 The first wind turbines
were developed in the
year 1891’s.
 The modern wind power
industry began in 1971.
 Mass production started
in 1979.
1883

11. Global wind energy production:-
 World wide wind generating capacity is less than 5000 MW in
1995.
 Global wind power installation increased by 35,467 in 2013,
bringing total installation capacity up to 318,137 MW.
 As of 2011, 83 countries around the world are using wind power on
a commercial basis.

12. Top 10 wind power countries:-
Worldwide there are now over
two thousand wind turbines
operating, with a total
capacity of 318,137 MW as of
end 2013.
As of 2011, the Roscoe Wind
Farm(781 MW) in the USA is
the world’s largest wind farm.
Thanet wind farm in UK is the
largest wind farm in the world
at 300 MW(2010).
Country Total capacity
end 2013(MW)
CHINA 91,424
USA 61,091
GERMANY 34,250
INDIA 28,150
SPAIN 22,959
UK 10,531
ITALY 8,552
FRANCE 8,254
CANADA 7,803
DENMARK 4,772
Rest of the world 48,351
Total 318,137

13. Growth of wind power:-
Wind energy is the fastest growing renewable energy source
in the world.
 The world wide installed capacity is growing at a rapid pace
of over 30% per year.

15. Wind power production in India:-
 The development of wind power in India began in the 1990’s.
 India has the fifth largest installed wind power capacity in the world.
 In 2009-10 Indi’s growth rate was highest among the other top four
countries.
 Suzlon, an Indian-owned company and by 2006 had captured
almost 7.7% of market share in global wind turbine sales.

16. State-level wind power:-
States Capacity as on
31.03.14(MW)
Tamil Nadu 7253
Gujarat 3414
Maharashtra 2976
Rajasthan 2820
Karnataka 2409
Andhra
Pradesh
753
Madhya
Pradesh
439
Kerala 55
Others 4.30
Total 21,264

17. Advantages of wind energy:-
Wind turbine require no
fuel.
 Land beneath wind turbines
can be used for farming and
grazing.
 Wind turbines do not produce
any waste, greenhouse gases,
toxins or by-products that can
harm the environment.
A good method of supplying
energy to remote areas.
Wind farms can be built
offshore.
Creates more jobs.

18. Environmental effects- Disadvantages:-
 Power density is very lower.
 Needs a very large number of wind mills to produce modest amounts of
power.
 Only practical in areas that are windy enough.
 Danger to birds.
 New (slow turning) designs largely eliminate this problem.
 Environmental costs.
 material and maintenance costs.
 Noise, birds and appearance.

19. Jobs in the wind Industry:-

20. Construction:-

21. Public relations/organizing support:-

22. Operations/
Maintenance

23. Engineering/

24. Environmental Impact Assessment:-

25. Conclusion:-
Wind energy is pollution free and nature friendly.
Wind energy has very good potential and it is the fastest
growing energy source.
The future looks bright for wind energy because technology is
becoming more advanced and windmills are becoming more
efficient.
Price of wind power is coming down.
Energy cost trends:-
1979:- 40 cents/kW
2000:-4 - 6 cents/kWh
