Wind Power Puffery: Overstated Claims

Wind Power Puffery
Summary of "Wind Power Puffery" by H. Sterling Burnett
Many believe that wind power is the best solution to this world's problem–it helps fuel infrastructures without causing air pollution and reduces
greenhouse gas emission (Burnett 247). However, H. Sterling Burnett, author of the article "Wind Power Puffery", suggests differently when he states,
"No, the truth is wind power's environmental benefits are usually overstated, while its significant environmental harms are often ignored"(247). Burnett
implies there are problems that come attached to wind power; the main one being wind towers only generate power within a certain range of wind
speed. He adds that wind towers being shut off due to wind speeds results in fossil fuel powered stations

Wind Power : Wind Turbines
The Answer Is Blowing in the Wind
Wind energy is a term used to describe the process by which the wind is used to generate electricity or mechanical power. This alternative energy
source is not a new technology. Wind mills, similar to wind turbines, have been in use since 2000 B.C. and were first developed in China and Persia.
Now with the increasing demand for renewable power, wind turbines or wind generators are beginning to be seen scattered over the countryside. Wind
power is believed to be a practical, renewable source of green energy. Wind turbines, like large aircraft propeller blades, turn in the moving air and
power an electric generator that supplies an electric current to power homes, businesses, schools and more. Modern wind ... Show more content on

Wind energy can be generated in most geographical areas, anywhere in the world where the wind blows consistently and with a strong enough force to
make wind energy generation efficient. The stronger the wind the more power produced. Some of the best locations for wind farms are large
agricultural areas and coastlines. This causes conflicts with other prime concerns, such as agriculture, urban development, or waterfront views.
Wind energy may seem to be only a clean and non–controversial renewable energy source, but wind energy turbines do have some environmental
concerns. The noise factor is one of those concerns, the sound may be disguised by the sound of the wind, but there is a definite noise from the
turbines. Analysts and engineers have worked to improve turbines so the noise is reduced. Other environmental concerns are the aesthetic issues they
cause to the land, and how the turbines possibly interfere with radar or telecommunications. Also the flying rotors take part in bird and bat deaths. Even
though they have these concerns they still have little impact on the environment compared to fossil fuels. These problems have also been either
resolved or greatly reduced through technological development. According to the wind energy foundation, "In 2013, roughly 168 million
megawatt–hours generated by wind energy avoided 95.6 million metric tons of carbon dioxide (CO2) – the equivalent of reducing power–sector CO2

Offshore Wind Power Essay
Title: Offshore Wind Power
Offshore wind power has become a need of the hour in renewable energy production due to the rising prices of oil and continually increasing demand
for a separate energy sector. Offshore wind has the prospective to deliver at least four times the current U.S. demand of energy, as per mentioned by
the Global Wind Energy Council. However, there are many challenges and advantages that are significant for us to comprehend.
Most of the offshore wind turbines are constructed in waters about 100 feet deep having a monopole that has been implanted straight into the seabed.
More multifaceted and costly tripod structures are required for the projects that are constructed further offshore so that a stable footing is ... Show more

This is compounded by the usage of bigger turbines; which is possible due to the relative ease of transferring bigger components via water. This cuts
out the requirement to construct more transmission lines through the country, thus eradicating demand for great quantities of fossil fuels.
Along with these benefits come many practical difficulties associated with offshore wind projects. Offshore projects are expensive, particularly when
paralleled with those projects which are land–based. The surface of ocean is a harsh place to maintain and build these structures. Due to this reason,
high winds that carry larger amounts of energy threaten the steadiness of wind turbines which causes installation to become much more rigorous and
costly. Furthermore, it also fetches the need for monitoring which is an expensive and automated system for maintenance. Underwater topography
presently describes the viability of installation as most current models use foundations rooted directly into sea beds that are shallow.
Industry Status
Europe has been the vanguard of innovation and novelty in offshore wind. In Denmark, the very first project of offshore wind was established in 1991.
Despite its present non–existence of noteworthy offshore capacity, the U.S. also has plans for the improvement of offshorewind power of the Atlantic
coast.

Advantages: * Wind energy is friendly to the surrounding environment, as no fossil fuels are burnt to generate electricity from wind energy. *
Wind turbines take up less space than the average power station. Windmills only have to occupy a few square meters for the base, this allows the
land around the turbine to be used for many purposes, for example agriculture. * Newer technologies are making the extraction of wind energy
much more efficient. The wind is free, and we are able to cash in on this free source of energy. * Wind turbines are a great resource to generate
energy in remote locations, such as mountain communities and remote countryside. Wind turbines can be a range of different sizes in order to
support varying population levels. * Another advantage of wind energy is that when combined with solar electricity, this energy source is great for
developed and developing countries to provide a steady, reliable supply of electricity. Advantages One of the greatest advantages of Wind Energy is
that it is ample. Secondly, wind energy is renewable. Some other advantages of Wind Energy are that it is widely distributed, cheap, and also reducing
toxic gas emissions. Wind Energy is also advantageous over traditional methods of creating energy, in the sense that it is getting cheaper and cheaper to
produce wind energy. Wind Energy may soon be the cheapest

Advantages Of Wind Power
As it can be seen, wind energy has helped Malawi in many ways but, what would the outcome have been if William had found a book containing
another renewable energy source? Would it have been nuclear or hydroelectricity (which is used in Malawi but isn't very effective)? Would he have
found a text covering geothermal energy, rendered useless in this region and give up? Nevertheless, these mysteries will never be solved, although
another with the possibility of being solved shows its face. What is another renewable energy source Malawi could use besides wind energy? Solar
energy. Along with the wind energy in Wimbe it is briefly stated that solar energy is also being used as well (287). What if Malawi switched over to
purely solar energy? How would people benefit this change? To decipher these intricate questions one must delve into solar energy in and of itself.
Solar energy is an alternate energy source (much like wind energy) which collects solar radiation (radiation– is a form of energy transfer, instead of
direct contact like conduction, radiation transfigures energy through electromagnetic waves) and converts it into useable electricity ("Advantages").
Why solar energy for this remote, poor nation? Compared to the present energy source (hydroelectricity) and wind energy it has many advantages.
Unlike windmills, solar panels have multiple uses; for one, the most obvious one, it provides electricity, additionally, solar panels can provide heat

The Wind Turbines Are A Dominant Method Of Harnessing Wind...
This paper discusses how scientists can help bring wind power into urban areas with limited space such as London, and make wind energy a
sustainable energy resource. Three–blade wind turbines are a dominant method of harnessing wind power, but this technology has drawbacks which
make it unsuitable for placement in London. Small Wind Turbines, owned by individuals and/or communities have attempted to fill the gap, but are
only capable of supplying lower levels of power than a city demands. This paper assumes that wind power will continue be used in combination with
other (renewable) energy sources, such as solar, tidal or nuclear power to meet the UK's future energy needs and sustain at least an equivalent lifestyle
to now.
3–blade wind turbines are the dominant wind power technology used by the UK and they are a strong force in the UK renewable energies market
(Renewable UK, 2014). As such, the market has invested in wind energy and drives a profitability mentality to renewables. There is public support for
using wind energy generally, but also concerns about the effects of (in particular) 3–blade wind turbines and Small Wind Turbines on human and
animal health, noise pollution, and their visual impact were they placed in sight of people's homes (Tatchley et al., 2016). These market forces spur on
innovation into wind energy which makes it more accessible.
Using wind turbines has helped put the UK on track to achieve deriving 20% of its energy needs from renewable sources

For example, one myth is that the turbines are very loud and distracting but, that is far form the case. Wind towers produce a "swishing" or
"whooshing" sound that only gets quitter as technology advances. As claimed by the American Wind Energy Association, "an operatingwind farm at a
distance of 750–1,000 feet is no noisier than a kitchen refrigerator or a moderately quite room" (American Wind Energy Association). All the wind
towers I've seen are at least double or triple that distance from any household so most people can't hear them at all anyways. Non–supporters say that
there are negative health effects linked to wind turbines but, that is so far from the truth. No ill health effects have ever been linked to wind turbines.
Only health benefits since the towers emit virtually no pollution (American Wind Energy Association). Non–supporters might also make the claim that
wind farms are unpredictable and unfair like many big businesses are sought out to be. However, the great thing about wind energy is you know
exactly what you're in for. Jeremy Payne of the Maine renewable Energy Association states that the "regulatory process is both predictable,

The Power Of Wind Turbines
Introduction
Today society shares enthusiasm about the expansion and increased production of alternative energy to meet the global energy needs, rather than
relying on the limited supply of fossil fuels. It is estimated, by the end of this century, the fossil fuels that sustain civilisation will be depleted. So to
prepare for the new age of energy production, development of renewable energy sources such as wind power is very important.
Wind & Wind Turbines
Wind is formed from the heating and cooling of the atmosphere, which causes air and air layers to rise, fall and move over each other. This movement
results in wind currents. The kinetic energy of wind can be transformed into electrical energy through the use of wind turbines.
There are two main types of wind turbines, horizontal and vertical axis. Vertical axis wind turbines (VAWT) have blades which are connected to the
vertical shaft. The horizontal axis wind turbines (HAWT) however all the main components on top of a tall tower. Since horizontal axis wind turbines
are the most common used, the report will focus on this design.
The Gearbox
As the wind passes over the blades it creates lift which causes the rotor to turn. The blades turn a low–speed shaft inside the nacelle. The gearbox
connects the low speed shaft to the high speed shaft and increases the rotational speeds from 30 – 60 rotation per minute (rpm) to around 1000 –1800
rpm. This is about the rotational speed required by most generators to produce

Wind Power: Nature's Gift
Wind power is a clean and renewable energy that, while at times unreliable, has very low upkeep cost and is growing at a rapid rate. While there is
currently enough wind power to provide many times our current energy need, it is unfeasible in reality. Wind power utilizes the kineticenergy of air and
uses it to power a generator to produce electricity. Even though dependence on wind power is impossible, it still can provide a strong, clean, quantity of
power to supplement current energy production.
Wind energy is essentially the conversion of the kinetic energy from air molecules in motion to mechanical energy which is generally then converted
into electrical energy. People have used wind power since 700 AD in... Show more content on Helpwriting.net ...
Wind power and solar power also tend to compliment each other; a study by the Massachusetts Maritime Academy has shown that generally, while
wind speeds are high solar power generation tends to be low and vice versa, so the two could be used in conjunct to make up for each other's
weaknesses.
The main cost of wind energy is in the initial investment in the construction of a wind turbine; the upkeep cost is generally marginal and lower than one
cent per kWhr. In general, wind power works by having air molecules move across the turbine blades transferring kinetic energy from the molecules to
the turbine, causing it to turn. As it turns, the mechanical energy can be used to perform tasks such as grinding grain. More commonly, the turbine
turns and utilizes a power generator to convert the mechanical energy to electrical energy.
While wind power is currently more expensive per unit of energy (the initial cost of construction is spread across a turbine's lifetime, generally around
20–30 years) than alternatives such as coal; wind power lacks the negative externalities that other energy sources produce, namely pollution, through the
formation of CO2, heat, and other waste materials. Once factors such as health problems, global warming, destruction of wilderness and such come
into play, wind energy becomes a very

Use Of Wind Power On The Environment
The U.S should send someone to time travel back to the past to decrease the release of harmful gases into the atmosphere and investing in renewable
ones. Even though time travel is not possible, when it is, this idea should seriously be considered. Renewable resources are always readily available,
including hydropower, wind power, solar power, geothermal power and biomass. The use of fossil fuels in theU.S is too much and needs to be reduced
(Stanford 2016). There are many renewable energy sources that we could switch to. Hydropower and Wind power are some of the easiest and
renewable resources ever. However Wind power is one of the most cost–renewable resources and therefore should be a choice that people should use.
Wind Power should have been harnessed and used widely many years ago. This is why traveling back in time to support the using of wind power.
After traveling back in time, I have decided that wind energy is the way to go. The world should use wind power, to decrease the very dramatic
effects of global warming that have happened in about 2000 years. Wind power should be used because it is abundant because wind is everywhere
and also it releases no harmful greenhouse gases into the atmosphere like most fossil fuels. Also by investing in wind power, it creates jobs for
people, getting the supplies, building, and maintained the wind power plant (Energy Gov 2016). Finally, wind power can also help you save money
because after making the wind turbine, little to no

It has to be AT LEAST 8.7mph to turn awind turbine. Another disadvantage about wind power is shadow flicker it is when the blades of the wind
turbine cause a shadow as it turns. It would cause unwanted repetitive shadows over neighboring houses or buildings, it could be mistaken for power
outages or even earthquakes. Finally, the sound of wind turbines they are not silent for the people that live near the wind farms would get unwanted
noise in their houses content during the day and at night.
Wind turbines are a great way of conserving energy,there are some disadvantages to it though, but here are some solutions to those disadvantages. A
solution to the problem of the loud sound of the wind turbines is that people who live in that area could get sound proofed walls. Even though it is

Wind Energy : The Benefits Of Wind Power
Wind Power can fulfil an significant amount of energy which is constantly needed for citizens in the 21st century as it is reliable when placed in the
right conditions. The benefits of wind power include clean energy source, reliance, affordable and cost efficient which is why it should be used more
commonly.
Wind turbines can be made in different to suite different situations they are needed for– they can even fit on yachts or buildings. Picture one shows
wind turbines on a Tasmanian farm.
These wind turbines are commonly located against coastlines as that is where the wind is strongest– which results in the most reliable continuous and
strong wind.
The science and technology behind wind power; the wind turbine is used to transform the kinetic energy from window into electrical energy that can be
used in house holds. This is completed by the wind turbines pushing air between the blades of the turbine and rotating the blades, the kinetic energy of
the air is transformed to the mechanical energy. Excess kinetic energy will be left in the wind as it travels away from the turbine. The mechanical
energy is than transported to the generator from the shafts and gears in the wind turbine– this is the process of how the electrical energy is made.

Furthermore, wind turbines are a renewable energy source. The definition of renewable energy is "Energy from a source that is not depleted when
used, such as wind or solar power." (Oxford Dictionaries, 2017) which proves

The Use of Wind Power Is the Answer for the Future
The use of wind power is the answer for the future. The use of wind power has developed from when it was first used to power ships in ancient
civilizations like trading botes that sailed the Nail Egypt. Wind power was then captured by wind mills on farms to produce mechanical energy.
This energy was then used to pump water to irrigate crops so farmers could have a more reliable harvest. Windmills also powered and to grinders
that that crushed up grains. In today's society wind turbines have been developed that makes wind a feasible source of fuel for America. Wind
Energy is no longer a simple idea of little importance. It has developed into a major and dependable source of energy. The dependence on fossil fuels
is a big problem in society however, if we take advantage of renewable technology like wind energy, the economy and the environment will benefit.
Wind turbines offer many positive advantages. They boost the economy, on a local and national level.Wind power is a clean energy source, and unlike
dirty fossil fuels. Wind power helps protect our planet by reducing pollution and lowering the amount of harmful emissions that contribute to global
warming. Wind is completely renewable, and is a domestic source which will decrease our dependence on other countries.
Wind turbines are not flawless, they do have some problems. One of the first problems is the limitation of wind power. Scene the turbines rely on
wind to generate electricity if there is no or vary little wind

The Present and Potential of Wind Power
Wind Power's Present and Potential
Abstract
As the global supply of fossil fuels becomes steadily lower, need is growing for new energy sources that are beneficial to the environment and

A substantial amount of wind power's appeal exists in the low amount of environmental impact it has; wind turbines do not produce atmospheric
emissions that cause acid rain or greenhouse gasses. If only twenty percent of the nation's electricity came from wind power, one third of emissions
that come from power plants could be eliminated. This fact is potent with worry over global warming still high.
Although wind is free, setting up the wind turbines is costly. The initial cost for a 10 kW system
Wind Energy 6l is between forty and fifty thousand dollars, which with the turbine life–span taken into account is equivalent to around 1.2 cents per
kilowatt–hour. The life–span measure of cost per unit energy puts wind power at a considerable advantage. Nuclear power's production cost equates
with 1.72 cents per kWh, natural gas comes to an average of 5.77 cents, coal 1.8, solar 2.1 and hydropower half a cent per kWh (Primavera. W.P, 2005).
This data show that, besides hydroplants, wind farms provide the best energy investment available to us–and wind power has an abundance of potential
that hydropower does not seem to have. There to be seems a good likelihood that wind power's piece of the energy pie will continue to grow for a
long time. Hopefully wind, in cooperation with other alternative sources, will have the capacity to make up for the future drop–off in the global supply
of non–renewable sources.

Wind Power And Energy Power
Abstract
Wind power is still the most promising renewable energy in the year of 2013. The wind turbine system (WTS) started with a few tens of kilowatt
power in the 1980s. Now, multi megawatt wind turbines are widely installed even up to 6–8 MW. There is a widespread use of wind turbines in the
distribution networks and more and more wind power stations, acting as power plants, are connected directly to the transmission networks. As the grid
penetration and power level of the wind turbines increase steadily, the wind power starts to have significant impacts to the power grid system.
Therefore, more advanced generators, power electronic systems, and control solutions have to be introduced to improve the characteristics of the wind
power plant and make it more suitable to be integrated into the power grid. Meanwhile, there are also some emerging technology challenges, which
need to be further clarified and investigated. The global electrical energy consumption is still rising and there is a steady demand to increase the power
capacity. The production, distribution and the use of the energy should be as technological efficient as possible and incentives to save energy at the
end–user should be set up. The deregulation of energy has lowered the investment in larger power plants, which means the need for new electrical
power sources may be very high in the near future. Two major technologies will play important roles to solve the future problems.

What Are Wind Power?
Wind Power
Why did you choose this product or service? What are its interesting features?
I chose wind power because it is a clean source of energy and I believe that as a global economy we are very badly in need of clean alternative
energy sources. The interesting features of wind power are that wind is a constant renewable source for our planet and mankind has been harnessing
the power of wind for many centuries. For centuries we have used the power from the wind for sailing and farmers used the power of wind to grind
grains and pump water. How profitable is it? What is its potential? To find its potential, perform a SWOT analysis.
The wind power or wind energy industry is a very profitable business. It has a high entry barrier due to the very expensive entry into this industry. That
high cost of entry means profit return is slower but it is much higher due to the extremely low operating costs.
SWOT ANALYSIS
Strengths
1.Free Wind – The energy created comes from the wind which is free and will not be subject to supply market fluctuations like other fuels. This means
very low operating costs.
2.Green Energy – Wind turbines while creating energy do not create the greenhouse gasses like some other sources of energy production.
3.Unlimited Resource – We will never run out of wind as long as the sun is around because wind is created by the sun heating the earth's atmosphere.
4.Small Footprint – Wind turbines take up a very small amount of land space.

Wind Energy : Wind Power
Wind energy is the use of air flow through wind turbines to mechanically power generators for electricity. Wind power has been used as long as
humans have put sails into the wind. Wind power is an alternative to burning fossils, is plentiful, renewable, clean, produces no greenhouse gas
emissions during operation, consumes no water, and uses little , or barely any land. Wind power gives variable power which is very consistent from
year to year, but it has significant variation over shorter time scales. It is used with other electrical power resources to give a reliable supply. The
first windmill used for the production of electricity was built in Scotland in July 1887 by Professor James Blyth of Anderson's College. The
development of of electric power caused wind power to find new applications in lighting buildings remote from centrally generated power. Awind farm
is a group of wind turbines in the same location used for production of electricity. A large wind farm may consist of several hundred individual wind
turbines distributed over an extended area, but the land between the turbines may be used for agricultural or other purpose. The Gansu Wind Farm is
the largest wind farm in the world, it has several thousand turbines. A wind farm may also be located offshore. Almost all large wind turbines have the
same design, a horizontal axis wind turbine having an upwind rotor with three blades, attached to a nacelle on top of a tall tubular tower. Offshore

Because of this, companies consider building windmills offshore where there are less obstacles and constant wind. The power of the windmill does
not only depend on the speed of the wind, but also the swept area, and the density of the air. Windmills are as equally effective as coal plants,
converting 30–40% of the wind?s kinetic energy into electricity (Wind Energy––Energy from Moving Air, 2005). Scientists like German physicist
Albert Betz have said that a windmill may convert 59% of the energy from wind (Wikipedia, 2005). According to some designers for windmills, even
though windmills do lose some wind energy, they still produce constant energy. Capacity, however, is somewhat lower; sitting at about 30
–35% (Wind
Energy––Energy from
Moving Air, 2005).
The declining supply of fossil fuels and the increasing pollution resulting from its use threatens our nation with a crisis. While fossil fuels can still
supply the world its energy for now, the depletion of fossil fuels will force us to find an alternative source of energy.
Scientists believe this will happen by 2050 (Food, Land, Population, and the US
Economy). The purpose of the lab report is to examine wind power by weighing its pros and cons to determine whether or not this can be a good
source of energy when we do run out of fuel.
Since developing an experiment is impossible for our studies, we will be looking at specific places in the United States or other

Wind power is important due to its long term strategy, since it uses natural energy and inexhaustible power. The location of wind energy is classified
in two types: Off shore and on shore wind energy. Off shore wind power refers to the installation and production of wind farms on water bodies such
as seas and oceans. Onshore wind power refers to wind energy generated on land.
The key features of wind energy are:
Wind energy do not require any active intervention, such as mining, extraction or burning for their construction and operation
Energy generated by wind is clean, environmentally friendly which does not release hydrocarbons or release any greenhouse gases into the atmosphere
(Spiropoulou et al.).
Uses comparatively less land compared to conventional sources of energy
Worldwide there is over two hundred thousand wind turbines installed which includes both on shore and offshore wind turbines. Europe is the global
leader in wind production followed by china, Canada, Australia and US.
Offshore and Onshore wind Energy
Offshore Wind Energy is large and is faced by fewer obstacles to planning of site than onshore wind turbines. Onshore wind farms are usually
economical compared to offshore wind farms in terms of installation, construction and maintenance. Offshore wind energy has comparatively less land
price.
Advantages of offshore wind energy are:

I.The nature of noise related symptoms in residents who reside within a certain proximity to wind turbines and wind farms.
Over the past several decades, there has been a resurgence in wind power. This technology is a clean renewable energy source that does not contribute
to global warming nor does it create any harmful wastes. As communities look to identify safe renewable energy sources many have turned towind
power; inspired by the numerous benefits and perceived benign risks many have attempted to harness wind power through wind turbines and wind
farms. As the Sun heats the Earth it creates wind. Due to the changing seasons and moving cloud coverage, the sun heats the Earth unevenly and this
uneven heating, in addition to the Earth 's rotation, causes warmer air to move toward cooler air resulting in wind. Although wind power is not new,
technological advancements have altered the image of the traditional windmill and have created new obstacles and environmental concerns for local
residents.
Wind power is harnessed using wind turbines, which transforms the energy into electrical power. Wind turbines are typically designed either on a
horizontal–axis or a vertical–axis. According to the U.S. Environmental Protection Agency, "horizontal–axis wind turbines have either two or three long
blades that collect the energy in the wind and convert it to electricity." Additionally, "the blades spin when the wind blows over them and the energy of
motion contained in the

Essay : Solar Power Is Superior To Wind Power
Solar Power is Superior to Wind Power
Have you ever thought about green energy? Well if you have, I am sure that you have heard of solar power and wind power. There are also other
forms of green energy but they are not used as much as solar or wind power, but solar and wind power are the most debated of all green energy. This
topic is controversial because the world is beginning to switch to renewable green energy and people and politicians are debating which energy source
they should use. In the end solar power is a better option than wind power.
There are many reasons why solar power is better than wind power. One of the reasons is that solar panels take less maintenance than wind
turbines. Standard warranties normally last 25 years, This includes any repairs and damages that could occur to the solar panel. An example of this
is if a tree were to fall onto a group of solar panels from a storm and it was within the 25 year warranty then the company that made the solar panel
would come and repair or replace the broken or damaged panels. Wind turbines have shorter warranties from the manufacturers and this should make
people less certain on its reliability. The solar panel companies also have a guarantee that a solar panel's efficiency wont drop below a certain
percentage over its lifespan, this percentage is normally in the range of 85–90% efficiency. Also solar panels are made of tempered glass which is

Establishing Wind Power
Establishing wind power as a major source of electricity can be costly and can have many disadvantages; however, there are many important
advantages that can come from wind power as well. Buying and installing a wind turbine is expensive. The cost to install a small "household–single
turbine" can be up to thirteen thousand, five hundred dollars (Gipe 125). One popular home wind turbine is the Skystream. With this turbine, home
owners would need to make thirty–five cents to forty cents per kilowatt–hour in order to make the amount of money it costs to acquisition this turbine
within the first ten years of owning the turbine that is estimated to last for approximately twenty years (126). The smaller the turbine, the more it will
cost. ... Show more content on Helpwriting.net ...
This has become one of the main concerns for people because energy can only be made while the wind is blowing. Some source of backup power is
necessary (Smith 52). Wind Power alone is not able to meet the needs demanded of it at all times, this is unless some of the power made during
periods of high wind can be stored through the use of batteries. Or another source of energy must be utilized to pick up the slack (per se), for example
hydropower (Maehlum). There are also many environmental factors that contribute to the disadvantages of wind energy. These factors include the
deaths of wildlife, disrupting noise, as well as the destruction of the landscape. Many birds, bats, and other various creatures that fly have lost their live
from head–on collisions with the blades of wind turbines. It has been estimated that around ten thousand to four hundred and forty thousand animals
have been killed by wind turbines. However, around nine hundred and seventy–six million birds have died from collisions with buildings. The loud
noise that wind turbines create has also been frequently reported as a problem by people living near wind farms (Maehlum). Last of all, many have
complained about a destruction of the landscape that wind turbines create because it destroys the scenic views (Alters). Also, viewers see wind turbines
as an "industrial encroachment in natural and rural landscapes." Shadow Flickering also can impact the environment in which wind turbines are

Wind Power
Harnessing the natural power of the wind is by no means a new concept. Asides from sailing, wind power has been utilised for many thousands of years,
principally for agricultural purposes. Basic windmills are thought to have been used in Persia (now Iran) as early as the 7th century AD. Their ability to
make use of otherwise untapped energy sources without the needs and costs of other alternatives, ensured that they remained the machines of
preference in several industries throughout both agricultural and industrial revolutions.
Whilst their basic concepts have remained true to the basic origins, technological advances have enabled engineers to adapt the mechanics of the mill to

This second type of machine is far less common due to its size, appearance, costs and noise levels. The result of the thousands of years worth of
innovation and development has led to the current style of machines available on the market.
The most powerful machines at the moment are multi–megawatt horizontal axis machines with 72m rotor diameters, mounted on 60m towers. Whilst
these machines are still prototypes under review, the potential for their expanded use in the future still remains a strong possibility (although for
machines of this size their siting will usually be off–shore). The most common type of modern turbine however, is the basic 500–1500KW horizontal
axis machine.
The science.
The wind turbine generators consist of several components. The blades are fitted to a central hub, which is connected to a gearbox via a low speed
shaft turning between 19 and 30 RPM. The gearbox increases the rotational speed to approximately 1500 RPM, which is a more acceptable speed for
the asynchronous generator to run at its optimum level. With the gearbox and generator running for long periods, wear and hence increased noise
would cause a nuisance. To tackle this problem, self–cooling and lubricating mechanisms are built into the turbines main housing (called the nacelle).
Also incorporated into the nacelle are yaw mechanisms, to ensure the blades are always

Wind Power : The Positive Effects Of Wind Energy
In a world full of pollution, we seek alternatives in energy productions that reduce and limit our carbon dioxide emission. Wind power has been used
for over 2000 years, initially using energy through windmills to pump water and grind grains. Wind currents depend on the temperature changes of the
sun and the sun is a constant variable of energy, makingwind power renewable. While wind seems to be a good option and is the fastest growing
energy source in the world, with the United States planning to rely 20 percent of its electricity on wind power by 2030, the benefit it produces does
not entirely contribute to decreasing global warming. Wind power generates only a small portion of the nation's energy and will reduce insignificant
amounts of carbon dioxide emission in the air. Wind power is also unstable and difficult to find an applicable area to built them. The tall and
enormous wind turbines require high wind to operate and poses a threat to wildlife. Despite the conventional power plants being far more polluting
than wind power, it provides a more stable and reliable energy source. Although wind turbines can reduce carbon dioxide emission, the positive
impacts of wind power are outweighed by the negatives: unreliability of wind, ineffectiveness of reducing large amounts of pollution, and damaging
effects on the environment. There are many great benefits that come along with wind power. Wind power is "the second largest new resource added to
the U.S. electrical grid

Wind Power is the use of our natural wind that converts it into mechanical energy which eventually becomes electricity. You may not realize this, but
we used wind power that dated centuries ago. It pumped water, ground grain, and plenty of other things. (Resources, awea.org)
Ever since recorded history, people had the ability to use wind as a source of energy.Wind power was been used to propel boats along rivers as early as
5000 B.C. At 200 B.C., China used windmills to pump water, while in Persia and the Middle East used vertical–axis windmills with woven reed sails

The wind power at 30 mph would equal: P=1/2(1.5) (1.5) (13.4) Ві = 2,707 Watts. The power increased by 8 times. Exemplary I must say. However,
there are factors played in the part of having a wind energy turbine in any area. The majors' ones are as followed:
Wind Speed
Proximity to airport
Proximity to residences
Transportation access
Distance to transmission lines
Environmental issues such as endangered species or wetlands
As long as you don't have much problems with the factors shown above, you can build yourself a wind turbine. To construct these things, the wind
turbine consists of three basic parts: the tower, the nacelle, and the rotor blades. The tower itself is either a steel lattice tower almost the same as
an electrical tower, or a steel tubular tower with an inside ladder to the nacelle. The first step in constructing the wind turbine, is to have a tower.
The steel parts are usually made off site in a factory, however, they are usually built on site. The parts are bolted together, and as usual, keeping the
tower horizontal until placement. Next is the fiberglass nacelle is installed. It's stuff inside such as the main drive shaft, gearbox and blade pitch and
yaw controls are created and mounted onto a base frame at a factory. The nacelle is a strong, hollow shell that has the inner workings of the wind
turbine. Towers do not have "guys," which are cables used for support. They are mostly made out of steel that has been coated with zinc alloy for

The primary important difference and similarity between solar and wind power is the amount of energy they produce. Both of them have different
capacities to store and provide energy. Currently, the significant difference between solar and wind power is the amount of energy available.
According to Ball (2012), in " Tough Love for Renewable Energy," solar energy currently produces approximately 0.1 of all energy in the world,
whereas wind power provides about 1.4% of global electricity. This means that sunlight energy has a little contribution to give the world its need
for electricity, while wind power is more popular than solar energy by providing much more energy. This shows the ability of producing renewable
energy. In the article" Rooftop Power," Priensitz, (2010) writes this amount of energy is provided by using solar panels and wind turbines. On the
other hand, in the future, both solar and wind power have the same amount of producing energy. Studies show that both solar and wind power are
able to produce about 10% of world electricity (Ball, 2012). These studies are predicated on the amount of renewable energy in 2035. In other words,
renewable energy will increase steadily in the future. As shown in the studies, renewable power will not supplant the fossil fuels energy because
conventional energy is cheaper. Accordingly,

The Benefits Of Wind Power
With the understanding that quantities of fossil fuels are depleting, consumers and power producers talk about the benefits of wind power. While there
are a few positive things about wind energy, their negative aspects outweigh the good qualities. Negative aspects such as inefficiency, poor location,
size, and demanding upkeep hinder wind power from expanding. With all of the undesirable traits of wind power there is no reason for researchers,
and engineers to continue investing time, money, and energy into harvesting wind power. Wind power has been harnessed as an energy source
long before it was developed to produce electricity. During the Industrial Revolution, wind power was used to, "pump water, grind grain, saw
lumber, and even turn carousels"(Chamberlain). With this being said, people now had easier lives due to the expansion and mechanisation of wind.
These tasks also led to fewer jobs, as machines could now take the place of laborers in these businesses and even slaves or indentured servants.
Before wind power was used in this form, water was the driving force behind these types of mechanisms. With wind being able to be used, sawmills,
and other businesses could now be located in different areas, since they were now not reliant of the current of a river. The development did not stop at
that. According to Fritz, Moses Farmer, an electrical engineer, developed a generator that produced power from windmills in 1860(1). The

Wind Power And The Wind Turbine System
Abstract
Wind force is still the most encouraging renewable energy in the year of 2013. The wind turbine system (WTS) began with a few tens of kilowatt
power in the 1980s. Now, multi megawatt wind turbines are widely installed even up to 6–8 MW. There is a widespread use of wind turbines in the
distribution networks and more and more wind power stations, acting as power plants, are connected directly to the transmission networks. As the grid
penetration and power level of the wind turbines increase steadily, the wind power starts to have significant impacts to the power grid system.
Therefore, more advanced generators, power electronic systems, and control solutions have to be introduced to improve the characteristics of the wind
power plant and make it more suitable to be integrated into the power grid. Meanwhile, there are also some emerging technology challenges, which
need to be further clarified and investigated. The global electrical energy consumption is still rising and there is a steady demand to increase the power
capacity. The production, distribution and the use of the energy should be as technological efficient as possible and incentives to save energy at the
end–user should be set up. The deregulation of energy has lowered the investment in larger power plants, which means the need for new electrical
power sources may be very high in the near future. Two major technologies will play important roles to solve the future problems.
One is to change the electrical

The Effect Of Wind Energy's Effect On Wind Power
One fact that investors will likely consider, is the debate over the effect of wind inconsistency, as well as wind speed on the effectiveness and overall
power generation by a wind farm. This is a significant consideration that many may not think of upon first learning of wind power as a potential
resource. Research on the effect of wind speed on wind power generation was performed by Eric Wright who states that wind speed had little effect
on power generation on South African wind turbines (Wright 2017). In fact, although climate change has led to an overall decrease in wind speeds
globally, the power generation was affected, at most 3.8 percent, and at the least 0.9 percent, which overall does not account for a large enough
percentage to cause concern over when considering investment (Wright 2017). Consistency is another aspect of wind power which makes it yet more
alluring over fossil fuels, which are dwindling in supply, and lacking in consistency.
The use of fossil fuels has led to global warming and climate change due to the carbon dioxide emitted when they are burned as fuel. Fossil fuels are
created over thousands of years, and once they are used, they are gone forever. Due to this and their continued use over hundreds of years, they are
becoming short in supply. They are becoming more expensive as they become rarer and it no longer makes economic sense to invest in the use or
production of fossil fuel power plants. On top of that their use is hurting the Earth and

A gearbox behind the blades, called the nacelle, is where the power of motion turns gears to generate electricity.
Wind energy can be stored by battery, pumped–hydro equipment, and other devices. Wind turbines are also often connected to a utility, which provides
back–up electricity when needed.
The location of wind turbines is as important to the generation of electricity as the design. Wind turbines function best in locations where average
wind speeds are high and constant. In the US, the best locations for wind turbines or wind farms (large groups of turbines set up in rows at especially
windy spots that generate megawatts of electricity) are along certain mountain passes and ridges in California and Hawaii, as well as the flat plain
regions of the Midwest, (AccessScience, "Energy in the Wind").
The Pros and Cons of Wind Power:
Wind is an environmentally friendly source of energy that avoids the bad aspects of fossil fuels and nuclear power. In addition to cutting down
pollution, wind turbines do not leave behind dangerous byproducts to dispose of like nuclear–generated power does. Also, while nuclear reactors and
coal and gas–fired electric plants guzzle water, wind turbines do not require any water at all. At Swarthmore College alone, 200,000 kilowatt–hours of
wind energy would displace conventional electric generation that would otherwise produce 140 tons of carbon dioxide, the primary source of global

Wind Energy And Wind Power
Wind power
Wind energy or wind power is extracted from air flow using wind turbines or sails to produce mechanical or electrical energy. Windmills are used for
their mechanical power, wind pumps for water pumping, and sails to propel ships.
Wind turbines operate on a simple principle. 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. Click on the image to see an animation of wind at work.
Wind turbines use the wind's kinetic energy to generate electrical energy that can be used in homes and businesses. Individual wind turbines can be

It is then mixed with hot air and blown into the firebox of the boiler. The coal/air mixture provides the most complete combustion and maximum heat
possible.
2.Water turns to steam
Highly purified water, pumped through pipes inside the boiler, is turned into steam by the heat. The steam reaches temperatures of up to 1,000 degrees
Fahrenheit and pressures up to 3,500 pounds per square inch, and is piped to the turbine.
3.Steam turns the turbine
The pressure of the steam pushing against a series of giant turbine blades turns the turbine shaft. The turbine shaft is connected to the shaft of the
generator, where magnets spin within wire coils to produce electricity.
Hydro electric
Hydropower plants capture the energy of falling water to generate electricity. A turbine converts the kinetic energy of falling water into mechanical
energy. Then a generator converts the mechanical energy from the turbine into electrical energy.
1.Raises the water level of the river to create falling water which powers the hydro turbine

2.The force of falling water pushing against the turbine 's blades causes the turbine to spin. A water turbine is much like a windmill, except the energy
is provided by falling water instead of wind. The turbine converts the kinetic energy of falling water into mechanical energy.
3.Connected to the turbine by shafts so when the turbine spins it causes the generator to spin also. Converts the mechanical energy from the turbine

How Wind Power Works
Wind power has been used over centuries (Bowden 44). It converts the energy form the wind into wind power with the help of wind turbines (How
Do Wind Turbines Work?). They can provide power for houses and farms. In order to fulfill the electricity needs of humans, large group of wind
turbines can work together as wind farms (Catherall 32).
Windmill is very green, it is very environmental friendly as it has no air pollution. It is clean and renewable. However, the wind speed and availability
is driving factor to run effective wind mill electricity system. It cannot be implemented without consistent wind with acceptable speed. (Layton)
Parts of turbine
A wind turbine consists of 4 main parts, which are the base, tower, blades and nacelle. The blades capture the energy from the wind, causing a
generator in nacelle to spin. The tower supports and provides access for maintenance to the nacelle. The tower is also containing electrical conduits.
The base is very important as it supports the whole structure of the wind turbine (Parts of a turbine).
How does it work?
Wind, the outcome of an even heating of the atmosphere from the sun, the earth's surface irregularities, and the earth's rotation, is a form of energy
from the solar (HOW DOES A WIND TURBINE WORK?). When the wind is passing through the blades, the two aerodynamic force that results on the
turning of the rotor blade are working. The strength of forces depends on of the amount of force that the wind exerts on them.

Renewable Energy : Wind Power And Geothermal Energy
The term "renewable" in the context of energy sources means that it can be utilized without depleting or weakening the supply. In other words, the
earth creates that resource at a rate faster than we can consume, therefore, we can use it without affecting the atmosphere and other natural resources.
Numerous forms of renewable energy that have been discovered and are now utilized, the two types I have decided to extensively research and focus
my post on are wind power and geothermal energy.
Wind Power
Wind turbines, formerly known as windmills, convert the power of wind into electricity. More specifically, wind creates kinetic energy, which causes
the blades to turn. Those blades are attached to a rotating shaft that creates and sends electricity to a power grid (EERE, n.d.a). The sun's rays
unevenly heating the planet creates wind, reasons for the inconsistent distribution of heat are uneven terrain and the earth's rotation around the sun
(EERE, n.d.b). It is considered a renewable energy since there will be wind as long as the sun heats the planet. Some of the most common placed for
this to happen is in large bodies of water and hill sides, anywhere wind is created.
Wind energy has been growing quickly due to its many advantages, two that I believe make the largest impact are how cost effective it is and that it
is a completely clean source of energy. It is one of the most cost–effective energy sources, only about $0.02 to $0.06 per kilowatt–hour (1,000 watts per
hour),
