The document discusses the history and technology of wind energy. It describes how wind is formed from uneven heating of the Earth's surface and how early civilizations first harnessed wind power. Modern horizontal axis wind turbines generally have three blades, a gearbox, generator, and tower. Larger turbines can generate megawatts of power. Wind energy is increasingly used to provide electricity for homes, communities, industry, and even entire countries. It is a renewable source that produces no emissions.

There are three basic ways to tap the ocean for its energy. We can use
The ocean's waves.
The ocean's high and low tides .
Temperature differences in the water.
1-Wave Energy
Kinetic energy (movement) exists in the moving waves of the ocean. That energy can be used to power a turbine. The wave rises into a chamber. The rising water forces the air out of the chamber. The moving air spins a turbine which can turn a generator.
When the wave goes down, air flows through the turbine and back into the chamber through doors that are normally closed.
2-Tidal Energy
Two types of tidal plant facilities.
Tidal barrages
Tidal stream generator
the prototype of floating solar power plant is goal of this minor project, in this project we only study of floating solar power plant and do some calculation for future projects of floating solar power plant.its all fact is based on search on inetrnet.
An alternate and eco-friendly energy source with a detailed explanation of types of turbines, their components along with the type of generator used, different wind farms, and production in India along with advantages and disadvantages.

WIND ENERGY REPORT AE 215- 2018 SOURCES OF FARM POWERmusadoto
Wind is the flow of gases on large scale. On the surface of the earth, wind consists of the bulk movement of air. In outer space, solar wind is the movement of gases and charged particles from the sun though space, while planetary wind is the outgassing of light chemical from a planet’s atmosphere into space. Wind by their spatial scale, their speed, the type of force that cause them, the region in which they occur and their effect. The strongest observed winds on planet in solar system occur on Neptune and Saturn. Winds have various aspects, an important one being its velocity, density of the gas involved and energy content of the wind.
Wind is almost entirely caused by the effects of the sun which, each hour, delivers 175 million watts of energy to the earth. This energy heats the planet’s surface, most intensively at the equator, which causes air to rise. This rising air creates an area of low pressure at the surface into which cooler air is sucked, and it is this flow of air that we know as “wind”. In reality atmospheric circulation is much more complicated and, after rising at the equator air travels pole wards. As it travels the air cools and eventually descends to the earth’s surface at about 30° latitude (north and south), from where it returns once again to the equator (a closed loop known as a Hadley Cell). Similar cells exist between 30° and 60° latitude (the Ferrell Cells) and between 60° latitude and each of the poles (the Polar Cells). Within these cells, the flow of air is further impacted by the rotation of the earth or the "Coriolis Effect". This effect creates a sideways force which causes air to circulate anticlockwise around areas of low pressure in the northern hemisphere and clockwise in the southern hemisphere
In summary, the origin of winds may be traced basically to uneven heating of the earth’s surface due to sun. This may lead to circulation of widespread winds on a global basis, producing planetary winds or may have a limited influence in a smaller area to cause local winds.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

4. 1-INTRODUCTION
Wind energy, the world's fastest growing
energy source, is a clean and renewable
source of energy that has been in use for
centuries in Europe and more recently in the
United States and other nations.
And todays world wind is one of the cheapest
and cleanest energy source.
5. 2-HISTORY of WIND MACHINES
• Throughout history people have harnessed the wind. Over 5,000 years ago, the
ancient Egyptians used wind power to sail their ships on the Nile River. Later
people built windmills to grind their grain. The earliest known windmills were in
Persia (the area now occupied by Iran). The early windmills looked like large
paddle wheels.
• Centuries later, the people in Holland improved the windmill. They gave it
propeller-type blades and made it so it could be turned to face the wind.
Windmills helped Holland become one of the world's most industrialized countries
by the 17th century.
• American colonists used windmills to grind wheat and corn, to pump water, and to
cut wood at sawmills.
• Last century, people used windmills to generate electricity in rural areas that did
not have electric service. When power lines began to transport electricity to rural
areas in the 1930s, the electric windmills were used less and less.
• Then in the early 1970s, oil shortages created an environment eager for alternative
energy sources, paving the way for the re-entry of the electric windmill on the
world landscape.
6. 3-WIND RESOURCE
Where Wind Energy Comes From
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.
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.
17
7. What Wind Is
Wind is simply air in motion. It is caused by
the uneven heating of the earth's surface by
the sun. Since the earth's surface is made up
of land, desert, water, and forest areas, the
surface absorbs the sun's radiation differently.
8. Wind Resources
• Global winds
• Local Winds
– Land Breezes and Sea Breezes
– Mountain Breezes and Valley Breezes
9. Global Winds
The wind rises from the equator and moves north and south in the higher
layers of the atmosphere.
Around 30°; latitude in both hemispheres the Coriolis force prevents the air
from moving much farther. At this latitude there is a high pressure area, as
the air begins sinking down again.
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.

35. Local Winds
• Land Breezes and Sea Breezes
Land masses are heated by the sun more quickly
than the sea in the daytime. The air rises, flows out
to the sea, and creates a low pressure at ground level
which attracts the cool air from the sea. This is called
a sea breeze. At nightfall there is often a period of
calm when land and sea temperatures are equal.
At night the wind blows in the opposite direction.
The land breeze at night generally has lower wind
speeds, because the temperature difference
between land and sea is smaller at night.
36. • 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. This results in a temperature inequity between
the two, and as warm air rises off the slopes, cool air
moves up out of the valleys to replace it. This upslope
wind is called a valley breeze. The opposite effect takes
place in the afternoon, as the valley radiates heat. The
peaks, long since cooled, transport air into the valley in a
process that is partly gravitational and partly convective
and is called a mountain breeze.
38. Horizontal Axis Wind Turbine
Most of the technology described in this project is related to
horizontal axis wind turbines (HAWTs,) as shown in figure 2.
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. The same basic principle is used in a
modern water turbine, where the flow of water is parallel to
the rotational axis of the turbine blades [5].
40. Vertical Axis Wind Turbine
• As you will probably recall, classical water
wheels let the water arrive at a right angle
(perpendicular) to the rotational axis (shaft) of
the water wheel.
• Vertical axis wind turbines (VAWTs) are a bit like
water wheels in that sense. (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).
41. • The only vertical axis turbine which has ever
been manufactured commercially at any volume
is the Darrieus machine, named after the French
engineer Georges Darrieus who patented the
design in 1931. (It was manufactured by the U.S.
company FloWind which went bankrupt in
1997). The Darrieus machine is characterized by
its C-shaped rotor blades which make it look a
bit like an eggbeater. It is normally built with
two or three blades.
43. Advantages of VAWT’s
1) You may place the generator, gearbox
etc. on the ground, and you may not
need a tower for the machine.
2) You do not need a yaw mechanism to
turn the rotor against the wind.
44. Disadvantages of VAWT’s
1) Wind speeds are very low close to ground
level, so although you may save a tower, your
wind speeds will be very low on the lower part
of your rotor.
2) The overall efficiency of the vertical axis
machines is not impressive.
3) The machine is not self-starting (e.g. a
Darrieus machine will need a "push" before it
starts. This is only a minor inconvenience for a
grid.
46. Why turbines not look like old-fashioned
windmills
The old-fashioned, as seen in figure 4, windmill is
viewed with nostalgia, and some people prefer the
look of them to that of their modern counterparts.
Just because wind turbines are modern, it does not
mean that they are less aesthetically pleasing. A
modern wind turbine is simply an improved windmill.
Every aspect of their design has been optimized, and
they are hundreds of times more efficient than old-
fashioned windmills. To make them look more old-
fashioned would result in much more expensive
electricity.
47. 5-WIND TRIBUNE USE
• Electricity for homes and farms
• Electricity for communities
• Electricity in industry
• Supplying electricity for a nation
• Remote communities
• Energy to drive pumps
48. Electricity from turbines
As shown in figure 5 a wind turbine consists of six major
components :
• A rotor that aerodynamically converts the wind energy into
mechanical energy on a slowly turning shaft.
• A gearbox that increases the rotor-shaft speed for the generator.
Some specially designed generators run at rotor-shaft speed and
do not need a gearbox.
• A generator that produces electricity.
• A control and protection system that optimizes performance and
keeps the machinery operating within safe limits.
• A tower that raises the rotor high off the ground where the wind
speed is greater and the effects of local obstructions are less.
• A foundation that supports the wind turbine system, sometimes
with the aid of guy wires.
49. • Figure 5 Major components of horizontal and
vertical axis wind turbines.
50. • Wind turbine generators produce a range of
electricity. Rotors that have diameters of
about 1m produce a few hundred watts of
electricity. Rotors that have diameters that
approach 75 m can produce over one
megawatt.
51. Electricity for Homes and Farms
Small and medium wind turbine generators at
homes, farms or small industrial sites can be
used with diesel generators or connected to the
electrical supply grid. By connecting to the
electrical grid, the user of the electrical supply
pays only for the electricity they use from the
electrical utility company.
52. Electricity For Communities
• Small numbers of medium/large wind turbine
generators can be installed by groups of
individuals wishing to contribute pollution-
free energy to their electricity networks.
53. Electricity in Industry
Medium systems (10 to 100 kilowatts) can be used
by large farms, process industries, and groups of
individuals to offset costs of electricity from the grid
network, or by remote communities to offset fuel
costs and pollution of diesel power plants.
Large systems (100 kilowatts to 1 megawatt) can be
used either individually or in small clusters to provide
electricity to industries, large farms, or groups of
dwellings. When used in arrays of multiple units,
they can supply significant amounts of electricity to
provincial or national networks.
54. Supplying Electricity For A Nation
Arrays of large wind turbine generators can be
connected to electricity supply grids and can
provide significant amounts of provincial and
national electrical demand. 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.
55. Remote Communities
• Small wind turbine generators that are
connected to batteries can provide sufficient
electricity for rural dwellings, communications
relay stations, navigational aids, and other
needs in isolated areas. Small and medium
wind turbines may also be used for pumping,
either by direct drive or by powering electric
pumps.
56. Energy To Drive Pumps
A wind turbine can be used to drive a rotating
or reciprocating pump. Like a wind turbine, a
wind pump has a rotor, a tower, and
foundations. However, the hydraulic pump
replaces the generator. Often, the rotor shaft
drives the pump directly, which eliminates the
need for a gearbox.
57. As shown in figure 6 the pump can be located in
the following places:
• on top of the tower at the turbine rotor shaft
• at ground level, in which case shafting or pulleys
are used
• at the bottom of the well, in which case a
reciprocating pump with a long "dipper rod" is
used.

systems.
59. 6-WIND ENERGY IN TURKEY
Turkish wind energy association was founded in
1992. by the help of energy ministry first turbines
built at İzmir- Çeşme-Alaçatı by ARES –GÜÇ BİRLİĞİ
co. This turbines produces 7,2 MW energy. In the
same years DEMİRER HOLDİNG built turbines at
Çanakkale-Bozcaada which produces 10,2 MW.
Today working is still going on to built new turbines
at İzmir- Çeşme, Çanakkale- Karacaören, Muğla–
Datça, Balıkesir- Bandırma [12].
60. 7-ENVIRONMENT
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.
However, any means of energy production
impacts the environment in some way, wind
energy is no different.
61. • 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.
62. • Noise
Like all mechanical systems, wind turbines produce
some noise when they operate. In recent years,
engineers have made design changes to reduce the
noise from wind turbines.
• TV/Radio Interference
In the past, older turbines with metal blades caused
television interference in areas near the turbine.
Interference from modern turbines is unlikely because
many components formerly made of metal are now
made from composites.
63. • Global Warming
Wind energy can help fight global warming.
Wind turbines produce no air emissions or
greenhouse gases.
64. 8-ECONOMICS
Ecomomics of wind energy based on
followings as shown in figure 7
• Wind source.
• Capital cost.
• Wind energy market.
• Technology.
66. • The cost of electricity from utility-scale wind systems
has dropped by more than 80% over the last 20 years
as seen in figure 8 and graph 1.
• Graphic (1) kwh cost ($/kwh) vs year graphic.
74. Wind Energy is the Fastest Growing Energy Source in the World!!
US installed capacity grew 45% in 2007 and 50%in 2008!!!
75. 2008: 8,358 megawatts (MW) of new wind energy
capacity installed
• 50% growth rate!
• Brings US total installed wind energy capacity
to 25,170 MW
• Enough electricity to power the equivalent of
close to 7 million households!
• 2009 was a slower year due to the economy
78. Modern Small Wind Turbines:

79. Does Small Wind Energy Pay?
• Does wind energy have to pay for itself?
– We often buy items of equivalent cost that provide no
monetary value, and often cost money to use
– Off grid customers are looking for least cost option
(connect to grid, diesel generator, solar/wind hybrid, etc..)
• Comparing initial costs is not useful
– Wind has no fuel cost
– Generators are cheaper per kW, but not necessarily
cheaper at producing energy over the entire life

81. The Siting Process
Wind Farm in Palm Springs, CA
•Where is the best
location for a wind
farm?
•Is the farm near the
power grid?
•Where is the wind
consistently strong?
•What is the weather
like?
82. Location, Location, Location!
•It is best to build a wind farm where wind
speed and direction has been studied for 1-
3 years
•Strong and steady winds are needed to
produce reliable electricity
•The site should not be prone to hurricanes,
tornadoes, etc.
Best sites:
•Hilltops
•Open plains
•Mountain passes
•Coasts
•Offshore
88. Wind Varies Daily
Wind varies daily not
only because of
weather but because of
convective heating
Winds typically
strongest in mid-late
afternoon
Convective heating is
less of an influence in
winter, when storms
dominate wind patterns
89. •Where is the wind?
•Where are the
population centers?
•Where are the wind
farms?
•How do we get wind
energy from the wind
farms to the population
centers?
Transmission Problems
90. Wildlife & Wind Power
•When siting a wind farm, developers must consider any possible wildlife
impacts.
•Though this was not the case in early wind farm development (1980’s), today
all proposed wind farms must undergo a strict environmental impact
assessment.
91. What about
the birds?
Wind Turbines kill very few
birds compared to other
human activities
Estimates are ~1-2 bird deaths
per turbine per year
Global warming is the single
biggest threat to wildlife today
A recent study in Nature found
that more than 1/3 of species
worldwide will be extinct by
2050 if global warming trends
continue
“As responsible citizens, stewards, and
advocates, Mass Audubon strongly supports
public policies and private projects that
advance energy conservation and efficiency.
We also support the development of wind
farms, as a renewable energy source to
offset the effects of global climate change
produced by the burning of fossil fuels.”
Sept. 21, 2004
92. Impact on Birds of Prey and Migratory Birds
•Do wind turbines affect migration
patterns of birds?
•Though the turbines do not kills many
birds each year, the total deaths could
eventually tip the species into decline.
•The majority of birds killed by wind
turbines are birds of prey
This experimental turbine built by
Northeast Wind Energy can be
lowered and turned off when birds
migrate through the area, or during
foul weather
•Birds of prey and wind developers are
both drawn to the same sites – hills and
ridges where the wind provides lift for
soaring birds
•Wind farms can create wind vortexes
that draw in birds and cause fatal
collisions with turbines
93. What About the Bats?
•Many bats die not from colliding with the
turbines, but from a sudden drop in air
pressure
•Their lungs cannot accommodate for the
change in pressure
•Bats can detect most human-made structures
through echolocation.
•An atmospheric-pressure drop at wind turbine
blades is undetectable through echolocation
•Many migratory bats and bats that live in
forest trees have been affected: the bats come
in at night to eat insects, and the effects of the
bat deaths can be far-reaching
•Proposals to turn off wind turbines
when wind speed is low at night and
bats are migrating to prevent more
deaths
94. Impacts of Wind Power:
Noise
• Modern turbines are
relatively quiet
• Noise can be mitigated
with setback distance
– Utility scale wind turbines
should be at least ¼ to ½
mile away from residences
95. Visual Impact
• Many people think wind turbines are “graceful, kinetic sculptures.”
• People who have never seen modern wind turbines in person are more likely
to think they will be an eyesore.
• People may complain that wind turbines look industrial and take away from
the natural beauty of the landscape
• Though people may support renewable energy, they may not want the
turbines in their “backyard”
– NIMBY
100. CONCLUSION
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.
101. • The costs for a utility scale wind turbine range
from about $1.3 million to $2.2 million per
MW of nameplate capacity installed. Most of
the commercial-scale turbines installed today
are 2 MW in size and cost roughly $3-$4
million installed
102. • According to the federal Energy Information
Administration, the "levelized cost" of new
wind power (including capital and operating
costs) is 8.2 cents per kWh. Advanced clean-
coal plants cost about 11 cents per kWh, the
same as nuclear. But advanced natural gas-
burning plants come in at just6.3 cents per
kWh.
103. • Globally, onshore wind schemes are now
costing an average of $0.06 per kilowatt hour
(kWh), although some schemes are coming in
at $0.04 per KwH, while the cost of solar PV is
down to $0.10 per KwH.
