Use of Wind Power to Reduce Greenhouse Gas Emissions

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

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 content on

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 offshore wind power of the Atlantic coast.
Energy consultants at Douglas and Westwood reported

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, making wind 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 : 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 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

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:
They require less land as compared to onshore wind farms and thus

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.
One is to change the electrical

Wind Power In Maine
Wind turbines are popping up all across the Pine Tree State. Mainers are divided on their feelings toward
the immense wind towers. Some say the turbines beneficial for Maine and its economy while others call

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 operating wind 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, reasonable and fair" (Porter, 2015). Payne is referring to the way wind
developers decide on and build location sites. Everything is very well predicted and laid out for all to

Wind Power is the use of our natural wind that converts it into mechanical energy which eventually

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 were

The wind power at 30 mph would equal: P=1/2(1.5) (1.5) (13.4) ³ = 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

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.

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.

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

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 make to withstand hail and other damaging weather. Solar panels don't

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

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. A wind 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

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.

As the global supply of fossil fuels becomes steadily lower, need is growing for new energy sources that
are beneficial to the environment and cost–effective. Wind power is one solution to this need. Wind
turbines require significant investment, but are cost–efficient in the long term. If construction of turbines is
sufficiently increased, the wind may be able to in the future provide a very major portion of global energy.
Wind Power's Present and Potential
According to a study by Archer and Jacobson, the wind power potential provided by just the windiest 13%
of the planet's land area is five times the power that we currently use – 72 terawatts (Archer, Jacobson,
2004). However, while the ... Show more content on Helpwriting.net ...
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.

ABSTRACT
The United States' main source of energy is currently fossil fuels. However, we know that fossil fuel
supply continues to deplete and sooner or later, the United States will need to resort to a new source of
energy. This report hopes to explore the advantages and disadvantages of wind power using model
regions. These regions have experience in using wind power, which may help us determine whether or not
it is a suitable source of energy when fossil fuels are completely drained. From examining Denmark and
other places benefiting from this clean and unlimited source of wind power, we believe that the

is only 16.1 km/hr
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

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.
5. Entry

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

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

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

A Brief Note On Solar And Wind Power
Solar and Wind Power
Nowadays, environmental and health scientists are concerned largely because of the damages caused by
conventional energy. In most cases, these damages are happening because people are more likely to use
fossil energy instead of renewable energy. In 1991, the worst disaster happened in the Arabian Gulf, and it
was closed to my hometown. It was an oil spill into the gulf sea. It's estimated more than 250,000 seabirds
died by oil spill (Laura Moss, 2010). This happened because the war beteween some Arabic Gulf
countries. As well as this, more than 85% of the consumed around the world comes from fossil fuel.

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,

Essay on Wind Power
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 kinetic energy 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

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. (Stelr,2017)
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

Solar Power Vs. 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 vs, wind power is one the most debated topics in 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. 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; and 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 of their reliability. The
solar panel companies also have a guarantee that a solar panel's efficiency won't 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 made to withstand hail and other damaging weather. Solar
panels don't have any moving parts like a wind

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),

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.

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 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 developments to continued

Solar And Wind Power Is The Best Choice For Many Scientists
Nowadays, environment and health scientists are concerned largely because of the damages caused by
conventional energy. In most cases, these damages are happened because people are more likely to use
fossil energy instead of renewable energy. In 1991, the worst disaster happened in the Arabian Gulf, and it
was closed to my hometown. It's estimated more than 250,000 seabirds died by oil spill (Laura Moss,
2010). However, solar and wind power is the best choice for many scientists to preserve the environment.
In the past, renewable power had some difficulties because most of the energy has obtained from
hydroelectric levees, whereas now produce more than quarter of the globe's energy (reading 1). As well as
this, more than 85 of the consumed around the world comes from fossil fuel energy. Unlike renewable
energy, fossil energy notably pollutes our plant. Due to population and other reasons, renewable energy
becomes more popular and getting attention from a lot of people (reading1). Ultimately, there are some
differences and similarities between solar and wind power in terms of their amount of energy and
advantages, and these sources has fundamental way to store their energy, which is through advanced
battery.
The primary important difference and similar between solar and wind power is their amount of energy.
Both of them have different capacity to store and provide the energy. Currently, the significant different
between solar and wind power is the amount of energy

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

The Wind Power Of Wind Turbines And Wind Farms
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 to wind 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

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 ("Advantages"). Although,

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

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.

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
