3. Wind turbines are produce power by help of
solar radiation that wind flow in earth by
temperature difference. The Statistics for the
power generation in various countries and
states of our country is also mentioned and we
will also look at the increase in power
generation between these years. Environment
is affected by wind turbine like noise pollution,
TV/Radio interference and also effect on the
birds.

4.  Wind is simply air in motion.
 Wind is a form of solar energy.
 Winds are caused by the uneven heating of the
atmosphere by the sun, the irregularities of the
earth's surface, and rotation of the earth[11].

5.  All renewable energy (except tidal and
geothermal power), and even the energy in
fossil fuels, ultimately comes from the sun.
 The sun radiates of 1.74 x 10 watts energy to
the earth per hour[1].
 About 1 to 2 per cent of the energy coming
from the sun is converted into wind energy.
 That is about 50 to 100 times more than the
energy converted into biomass by all plants on
earth [2].

6.  Global winds
 Local Winds
 Land Breezes and Sea Breezes
 Mountain Breezes and Valley Breezes

7.  The wind rises from the equator and moves
north and south in the higher layers of the
atmosphere [2].
 Around 30° latitude in both hemispheres the
Coriolis force prevents the air from moving
much farther.
 As the wind rises from the equator there will
be a low pressure area close to ground level
attracting winds from the North and South.
 At the Poles, there will be high pressure due to
the cooling of the air [3].

9. 1. Land breezes and sea breezes
 Land masses are heated by the sun more
quickly than the sea in the daytime.
 The land breeze at night generally has lower
wind speeds, because the temperature
difference between land and sea is smaller at
night [2].

11. 2. Mountain breezes and Valley breezes
 Mountain breezes and Valley breezes are due
to a combination of differential heating and
geometry.
 When the sun rises, it is the tops of the
mountain peaks which receive first light, and
as the day progresses, the mountain slopes
take on a greater heat load than the valleys[4].

13.  Wind power is the use
of air flow through wind
turbines to mechanically
power generators
for electric power.

14.  Horizontal Axis Turbine
 Vertical Axis Turbine
 Old-fashioned windmills

15.  The reason is simple: All grid-connected
commercial wind turbines today are built with
a propeller-type rotor on a horizontal axis (i.e. a
horizontal main shaft).
 The purpose of the rotor, of course, is to
convert the linear motion of the wind into
rotational energy that can be used to drive a
generator[5].

17.  Vertical axis wind turbines are a bit like water
wheels in that sense.
 the main components are located at the base of
the turbine.
 Some vertical axis turbine types could actually
work with a horizontal axis as well, but they
would hardly be able to beat the efficiency of a
propeller-type turbine[5].

19.  A windmill is a mill that converts the energy of
wind into rotational energy by means of vanes
called sail or blades.
 windmills usually were used to mill grain,
pump water or both[6].

21.  Electricity for homes and farms
 Electricity for communities
 Electricity in industry
 Supplying electricity for a nation
 Remote communities
 Energy to drive pumps

22.  Small and medium
wind turbine
generators at homes,
farms or small
industrial sites can
be used with
connected to the
electrical supply
grid[7].

23.  Community wind projects are locally owned
by farmers, investors, businesses, schools,
utilities, or other public or private entities.
 Who utilize wind energy to support and
reduce energy costs to the local community[7].

25.  Medium systems (10 to 100 kilowatts) can be
used by large farms.
 Large systems (100 kilowatts to 1 megawatt)
can be used either individually or in small
clusters to provide electricity to industries,
large farms[7].

27.  Arrays of large wind turbine generators can be
connected to electricity supply grids.
 In Denmark, for example, wind-generated
electricity now provides about 10 % of national
needs and is scheduled to provide 50 % of the
need by 2030 [7].

29.  Small wind turbine generators that are
connected to batteries can provide sufficient
electricity for rural dwellings.
 Small and medium wind turbines may also be
used for pumping, either by direct drive or by
powering electric pumps [7].

31.  A wind turbine can be used to drive a rotating
or reciprocating pump.
 Wind turbine, a wind pump has a rotor, a
tower, and foundations.
 The hydraulic pump replaces the generator.
 The rotor shaft drives the pump directly[7].

33. Two types of wind power plants installed
 Offshore power plant
 Onshore power plant

34.  offshore turbines are located out at sea or in
freshwater[10].
Top three offshore power plants in the world
1) UK {London Array} – 630MW
2) Netherlands {Gemini wind farm} – 600MW
3) Germany {Gode wind} – 582MW

36.  Onshore wind refers to turbines located on
land.
Top three onshore power plants in the world
1) China {Gansu wind farm} – 7965MW
2) India {Muppandal wind farm} – 1500MW
3) USA {Altra wind energy center} – 1320MW

38.  Wind energy is now the 2nd fastest growing
source of electricity in the world.
 wind power amounted to 486.79 GW, an
increase of 12.5% compared to the previous
year.

39.  2006 to 2016 increase the capacity 7.4GW to
486.9GW in world.
 China installed 23.3 GW of wind power
capacity in 2016.
 China has a 1st rank in power generation by
wind turbines in the world.
 China set an ambitious goal of 5 GW of
installed offshore wind capacity by 2015 and 30
GW by 2020[12].

40.  China has about 2,380 GW of exploitable capacity
on land and 200 GW on the sea.
 The installed capacity of wind power in
Germany was 50 GW in 2016.
 wind power producing about 10.27 percent of
Germany’s total electrical power[11].

46.  Wind energy is considered a green power
technology because it has only minor impacts
on the environment.
 Wind energy plants produce no air pollutants
or greenhouse gases[8].

47.  Aesthetics and Visual Impacts
Elements that influence visual impacts include
the spacing, design, and uniformity of the
turbines.
 Birds and Other living Resources
Preconstruction surveys can indicate whether
birds or other living resources are likely to be
affected by wind turbines.

48.  Noise
1) All mechanical systems, wind turbines produce some
noise when they operate.
2) Engineers have made design changes to reduce the noise
from wind turbines.
 TV/Radio Interference
1) Older turbines with metal blades caused television
interference in areas near the turbine.
2) . Interference from modern turbines is unlikely because
many components formerly made of metal are now
made from composites.

49.  Global Warming
Wind energy can help fight global warming. Wind
turbines produce no air emissions or greenhouse
gases [9].

50. This is true that today's world need more clean and
more cheap energy. As I try to mentioned in this
project wind energy is the one of the best way of
clean and cheap energy. And also it is understood
that in the future most of our energy source will
based on wind energy.
