The Disadvantages And Pros And Cons Of Geothermal Energy
Energy is everywhere: you can feel it; you can listen to it; you can step on it. In the 21st century,
scientists and engineers made a huge progress in the development of different types of alternative
energy sources, the most popular of which are solar energy, wind energy, and geothermal energy.
However, people knowing all the advantages of these energy types, in many cases, cannot afford
them because of several problems. Geothermal energy is a developing technology that extracts the
heat from the Earth. In order to increase the prevalence of it, engineers are trying to eliminate the

According to Gupta, the advantages of geothermal energy are that it is a renewable and
environment–friendly source, it needs small spaces, it can be extracted anywhere, and it does not
depend on the weather (50). But the part that scientists are concerned more about is the cons of the
geothermal energy, because they does not allow the technology to be widely used all over the world.
To understand the most common problems connected with this technology, I searched more articles
on this topic and found the academic article "Geothermal Energy: Delivering on the Global
Potential" by Paul L. Younger, who analyzed some advantages and disadvantages of the geothermal
systems. According to Younger, although the geothermal energy has higher efficiency than wind or
solar energy systems, it remains the least developed among them because of uncertainties about the
availability of geothermal resources in many regions and high concentration of expenses at early
stages of using the geothermal systems (Young 11748). The author concludes that advances in
drilling technologies and improvements in the management of shallow recourses can lower the
installation cost of geothermal systems

Geothermal Energy Potential For Solar Energy
For Longmont, solar energy may be the best option, although Hydro power, Biomass, and
Geothermal all present options. For Utica, solar energy potential was very low, while the potential
for Hydro power is high and most likely that best option. For Cedar Rapids, solar energy potential
was also relatively low, while Biomass presents the greatest potential. Yuma has extremely high
potential for solar energy, so this seems to be the best option, but also has high potential for
Geothermal energy and Hydro power.
I would recommend the following to Mr. Greene for each of the four locations:
Longmont, CO: 70% Solar, 30% Geothermal
Utica, NY: 100% Solar
Cedar Rapids, IA: 30% Solar, 70% Biomass
Yuma, AZ: 80% Solar, 20% Geothermal

Geothermal Energy Is Heat Energy Coming From The Earth
1. Introduction
Geothermal energy is heat energy coming from the Earth. Geothermal energy is relatively cost
effective, reliable, and friendly to the environment, but is limited to some specific areas. Recent
technology development has greatly expanded the range and size of geothermal energy resources.
Now the geothermal energy can be also used for applications such as home heating, which add use
potential for the resource. Although, tapping geothermal energy will release some gas pollution
which are originally trapped deep inside the earth, these emissions are much lower than those of
fossil fuels. Therefore, geothermal energy is a kind of potential energy and may help to reduce air
pollution and greenhouse gas emissions of the earth.
California, with its location on the Pacific "Ring of Fire," has great potential of geothermal energy,
which can easily meet the consumption of electricity for 100,000 residents. According to EIA [1],
the monthly average consumption per person is 557kWh, we can get,
Total Capacity = (557 ×12 kWh/year×100,000)/(365 ×24 ×0.92h/year) = 83 MW
Therefore, our geothermal power plant capacity is 83MW.

Coal Vs Geothermal Energy Essay
How might Kentucky be losing money by using coal? They're not using geothermal energy, of
course. Currently, Kentucky's main source of energy is coal, which creates pollution, adding to
global warming. Geothermal energy is the heat, or thermal energy, of the earth. Both Geothermal
energy and the Chemical energy in coal are converted into electrical energy with the use of water,
which, when heated enough, becomes steam. Geothermal energy does not produce pollution. Coal,
however, does not. Electrical energy powers our lights, machines, air conditioners, and so many
more things. Geothermal energy can also utilized to heat our homes, as we transfer the thermal
energy from underground to the surface. By replacing coal energy with geothermal energy,
Kentucky will save coal for later, allowing Kentucky to sell coal to the surrounding states.
Geothermal is a much better option than coal because Geothermal energy is environmentally
friendly, efficient, and frees up coal for use in other things. ... Show more content on Helpwriting.net

To begin with, Geothermal energy does not generate pollution. As coal power plants release the
chemical energy inside the coal and transform that energy into electrical energy, they leave behind
coal ash, while Geothermal energy does not leave behind anything. Coal ash can pollute the water it
is dumped into, poisoning us, as coal ash contains mercury, cadmium, and arsenic. In addition,
geothermal power plants have the smallest carbon footprint of any heating or cooling source.
Something's 'carbon footprint' is how much it contributes greenhouse gases to global warming, as
geothermal energy produces little to no greenhouse gases when transformed into electrical energy.
Finally, geothermal power plants have little to no effect on the landscape. Most of the geothermal
power plant is underground, leaving actual plants more land they could grow on. However, how
could Geothermal energy be

drive turbines which power electricity generators. geothermal schematic
There are 3 types of geothermal power plants in use today, and they are: geysers Dry Steam
SchematicDry Steam Plants which use geothermal steam directly. Dry steam power plants use very
hot (>455 °F, or >235 °C) steam and little water from the geothermal reservoir. The steam goes
directly through a pipe to a turbine to spin a generator that produces electricity. This type of
geothermal power plant is the oldest, first being used at Lardarello, Italy, in 1904. An example of a

Government–funded research into obtaining geothermal energy was greatly dynamic in the 1970s
and early 1980s. However, as oil prices declined in the mid–1980s, alternative energy sources
declined, thus, funding for geothermal energy research greatly reduced. Consequently, this monetary
difficulty stifled any advancement on geothermal technology. "Now that energy concerns have
resurfaced, an opportunity exists for the U.S. to pursue the EGS [Enhanced Geothermal Systems]
option aggressively to meet long–term national needs," as observed by MIT Professor Jefferson
Tester (MIT, January 22, 2007, para. 19). Based on previous studies, there is evidence that
geothermal energy has a hopeful future in helping the United States. To study the potential use of

Fossil fuels (oil, coal, natural gas) take up about 80 % of total energy consumed. Fossil fuels cause
pollution and global warming yet we continue to use them. Our demand for fossil fuels has become
so great that according to current projections, Earth's reserves will be depleted within the next 200
years. But we do not actually have 200 years to wait. Our run–away consumption of fossil fuel not
only endangers our ability to meet our future energy needs but also the environment. Fossil fuels
cause significant pollution and global warming. This in turn compromises wildlife habitats and can
even lead to extinction of animal and plant species. By looking at new sources such as geothermal
energy, we can move towards a source that is not extremely harmful and yet still effective.
Geothermal Energy
Geothermal energy is heat energy that is stored underneath Earth's surface. It is mainly found at
volcanoes, hot springs, or geysers. Heat stored in the hot water and steam found at these locations is
captured and can be used to heat buildings or generate electricity. This energy source is renewable
because heat from the earth is continuously produced. To obtain energy, you must either use hot
water or steam from the source. The most common way of capturing the energy from geothermal
sources is to tap into naturally occurring "hydrothermal convection" systems where cooler water
seeps into Earth's crust, is heated up, and then rises to the

Geothermal Energy And Natural Energy
Just beneath your feet, lies an unimaginable amount of heat. Water in the Earth collects into very hot
pools, known as geothermal reservoirs. Scientists have discovered that we can harness energy from
this natural heat source and use it for our benefit. Electricity, agriculture, aquaculture are just the
basic ways that geothermal energy is used. There are also many creative and helpful uses for it, such
as in spas or thawing ice on roads. So what exactly is geothermal energy and how does it work? The
project we have carried out answers these exact questions. This energy source is one of great worth,
especially in our modern day.
The word Geothermal literally means "heat from the earth". The Earth has 4 levels: crust, mantle,
outer core, and inner core. The crust acts as an insulator for the immense heat coming from below
which is an efficient universal resource. The next section, the mantle, begins at a depth of 1250
miles and is only semi–molten. The third down, the outer core, starts at 2500 miles and is
completely liquid. Finally, the inner core is solid and is made of nickel and iron. It starts at a depth
of 4,000 miles and is 9,000 degrees fahrenheit.

First scientists discover a hot spot or area with a lot of volcanic activity, and then they drill into the
earth very deep. Then one pipe leads straight up to the earth's surface containing hot air, gas, or fluid
of some kind coming from the earth's inner core. This hot fluid, generally steam, is caught in the
turbine that was created to run the plant. This turbine then revolves to create the energy needed for
the generator. Of course, as seen in the figure, there is an injection well so that the hot air/fluid can
be pumped back into the earth to create a cycle.
How the steam is created into electricity from the generator
With this form of using a generator to utilize the steam naturally pumped up from the inner part of
the earth, geothermal energy is able to be produced and then that energy, in the form of electricity, is
pumped and directed to where it needs to go.
Figure 2. This figure shows in even more detail how the electricity is powered through the generator
and then given to the areas that require that energy. As you can see in the diagram, the "production
well" brings in the hot air/steam which is then pumped through the "heat exchanger." This is all then
passed to the turbine to allow it to move freely and spin to create the needed electricity through the
generator. Then once the air has pushed the turbine it is then pumped back into the ground through
the "injection well."
This is basically how all of this works. It is a pretty simple concept

Disadvantages Of Geothermal Power
What is Geothermal Energy?
Geothermal energy is to a more or less
extent, extracting power/energy from Earth's internal thermal heat.
How do Geothermal Power Plants Produce Energy?
To produce electricity/energy, wells are
dug a mile or so deep into underground reservoirs. They tap steam and hot water which drives
turbines that are connected to electricity generators.
What Are The Different Types of Geothermal Power Plants?
There are three types of geothermal power plants: binary, flash, and dry steam.
In binary geothermal power plants they use hot water and pass it by a secondary fluid, this fluid as a
lower boiling point, causing the secondary fluid to become a steam that drives the turbine.
In flash geothermal power plants they use steam made by rom pulling high pressure hot water into
cooler low–pressure water. They then use the steam to drive the turbines.
Finally, in dry steam geothermal power plants they also use steam, but get the stream from out of
fractures in the surface and used it to drive the turbine directly. It is one of the oldest forms of
harnessing geothermal energy.
Benefits and Disadvantages of Geothermal Energy

Harnessing Geothermal Energy
Geothermal energy is the thermal energy stored in the Earth that is 20% due to the formation of the
Earth and 80% due to decaying radioactive materials. This thermal energy radiates off of the rocks
in the core, mantle, and lower crust and takes the form of heat. In fact, "the amount of heat within
10,000 meters of Earth 's surface contains 50,000 times more energy than all the oil and natural gas
resources in the world." The water underneath the crust can reach temperatures of around 200°C.
This heat excites the water molecules trapped beneath the surface and causes them to move faster
and spread farther apart, which is another way of saying that the water is evaporated. There are also
pathways through the rock that allow this superheated steam and sometimes water (geysers) to rise
up from under the crust and escape to the surface. The steam is a source of energy that costs nothing
to find, and the only difficulty is figuring out an efficient method of extracting that energy.

The continental crust consists of igneous and sedimentary rocks. The oceanic crust consists of the
same with a substantial layer of sediments above the rock. The crust covers the outer ridged layer of
the earth called the lithosphere. The lithosphere is divided into seven main continental plates.
These continental plates are constantly moving on a viscous base. The viscosity of this base is a
function of the temperature. The study of shifting continental plates is called Plate Tectonics. Plate
Tectonics allows scientists to locate regions of geothermal heat emission. Shifting continental plates
cause weak spots or gaps between plates where geothermal heat is more likely to seep through the
crust. These gaps are called Subduction Zones. Heat emission from subduction zones can take many
forms, such as volcanoes, geysers and hot springs. When lateral plate movement induced gaps occur
between plates, collisions occur between other plates. This results in partial plate destruction. This
causes mass amounts of heat to be produced due to frictional forces and the rise of magma from the
mantle through propagating lithosphere fractures and thermal plumes sometimes resulting in
volcanism. During plate movement, continental plates are constantly being consumed and produced
changing plate boundaries. When collisions between plates occur, the crust is pushed up sometimes
forming ranges of mountains. This is the way that most

Geothermal Energy from the Earth
Geothermal energy
Energy from the Earth What could be more natural or plentiful? The source of geothermal power is
the heat contained inside the Earth; heat so intense that it creates molten magma. There are a few
different types of geothermal energy that can be tapped. "Some geothermal systems are formed
when hot magma near the surface (1,500 to 10,000 meters deep) directly heats groundwater." The
heat generated from these hot spots flows outward toward the surface, manifesting as volcanoes,
geysers, and hot springs . Naturally–occurring hot water and steam can be tapped by energy
conversion technology to generate electricity or to produce hot water for direct use. "Other
geothermal systems are formed even when no magma is nearby as magma heats rocks which in turn
heat deeply–circulating groundwater." In order to maximize the energy gleaned from these so–called
"hot dry rocks," geothermal facilities will often fracture the hot rocks and pump water into and from
them in order to use the heated water to generate electricity.
The concentration of geothermal energy at any given location must be quite high in order to make
heat extraction feasible, and not all geothermal sites are created equally. Regions that have well–
developed geothermal systems are located in geologically active areas. These regions have
continuous, concentrated heat flow to the surface. The western United States has the best geothermal
regions in the country, while Iceland , New Zealand , the Philippines ,

Geothermal Energy: How Does It Work?
What is it? How does it work?
Geothermal energy is the use of the Earth's heat as energy, hence geo– (earth) and –thermal (heat).
Geothermal energy is generated in the Earth's core by the decay of highly unstable radioactive
particles, which create heat when decayed. Geothermal energy then moves toward the surface
through the mantle, mostly near where tectonic plates (the geological divisions of the Earth) meet
via convection currents. This energy heats holes in the Earth that are filled with water, which are
known as reservoirs. This makes steam, which can be piped up to either district heating systems (to
heat houses, businesses, etc.) or geothermal power plants (to make electricity which are sent to
houses, businesses, etc.). One place ... Show more content on Helpwriting.net ...
They can do this by creating an artificial well, which is drilled and heated by humans. Geothermal
energy is still new in Vermont but is being recognized as reliable and feasible. While it is expensive
to install (as much as $5,000 per ton), it is worth the deal as it lowers the price of heating bills to
about 20% of the cost of using propane. Plus, a geothermal heat pump normally lasts for more than
20 years. Overall, the use of geothermal energy can vary from a small usage to a large usage. It is
most likely to be useful for smaller operations such as individual buildings because of the small
amount of space that they tend to take up. The fact that utility companies would need a large number
of geothermal heat pumps and space for them to power and heat a town or city is another reason of
why geothermal energy might not bode well for larger utility companies. However, they could be
useful on a larger scale for utility companies who want to make money as it is a cheap and
renewable energy source that doesn't harm the environment and is available 24 hours a day. Also, it
might be easier for a utility company to get a geothermal heat pump than it is for a person because
of the cost of the pump

Essay Geothermal Energy: The Alternative of the Future
Geothermal Energy: The Alternative of the Future When the energy crisis hit Americans in the
1970's, people were scrambling to find ways to conserve energy. The crisis brought to attention the
very real shortage of fossil fuels. Gas and oil prices skyrocketed, and Americans looked for ways to
save energy. They started producing smaller cars, driving less, and turning down their thermostats.
Also, they started to examine alternate energy sources, such as solar, geothermal, and biomass. For a
while, Americans were making a conscious effort to cut back on the use of fossil fuels. However,
when gas and oil prices started to go back down in the early eighties, many of the conservation ideas

Currently, the U.S. buys most of its oil from Middle Eastern countries. What happens if our foreign
trade with the Middle East does not hold up? The unstable foreign trade lead to the energy crisis of
the 1970's, and it could happen again without much warning. A glimpse of this could be seen during
the Desert Storm conflict, when oil prices went up. In a more serious situation, the U.S. is stuck
without an energy source.
These are major problems that need to be addressed, before suddenly we are without energy. We are
not saying that we need to ban the use of fossil fuels, maybe we need to just start looking seriously
into alternate energy sources. The most obvious source right now seems to be solar energy; however,
there is another renewable resource that many people might not know about. Geothermal energy is a
resource that does not harm the environment, and is not dependent on foreign trade ("Geothermal
Heat Increases," 1998). No fuel is burned when the plants are operated. This cuts down on the
amount of carbon dioxide and other gases formed during the combustion of fossil fuels, producing
one–sixth the amount of carbon dioxide that natural gas plants do, and none of the nitrous oxide or
sulfur bearing gases ("Geothermal Energy Technical Site," 1997). Geothermal energy is also easy on
the land because there are no mineshafts, tunnels, open pits, waste heaps, or oil spills ("Geothermal

Abstract
This report presents an alternative energy is any energy source that from fossil fuel. We need to turn
to alternative energy in general. Firstly, we were in danger of ruining the planet's climate through
fossil fuel emissions. Furthermore, we cannot keep using fossil fuels forever that will run out
someday [1]. In addition, the problem of the current energy that we can focus was energy security
and independence viewpoint because our nation has increased its dependence on foreign oil supplies
instead of decreasing it especially from nations under the rule of a dictator or unstable countries
where human rights violations are common [2].
1.0 Introduction
Nowadays, many power stations across the world burn fossil fuels to generate energy. When fossil
fuels are burned to generate energy, they lead to increased concentrations of carbon dioxide and
Sulphur dioxide into the atmosphere which contributes to global warming. However, stocks of fossil
fuels are limited and alternatives need to be found. Alternative energy sources are a popular topic of
conversion these days, as many of them believe that they can hold a promising solution to meet our

The Benefits Of Geothermal Energy
Geothermal energy is the heat from the Earth. It's clean and sustainable. Resources of geothermal
energy range from the shallow ground to hot water and hot rock found a few miles beneath the
Earth's surface, and down even deeper to the extremely high temperatures of molten rock called
magma. We can also use geothermal energy to make electricity. A geothermal power plant works by
tapping into steam or hot water reservoirs underground; the heat is used to drive an electrical
generator. Most geothermal plants are located in the western United States, where hot water
reservoirs are common. History says that the first use of geothermal energy occurred more than
10,000 years ago in North America by American Paleo– Indians. People used water from hot springs
for cooking, bathing and cleaning. The first industrial use of geothermal energy began near Pisa,
Italy in late 18th century. Steam coming from natural vents (and from drilled holes) was used to
extract boric acid from the hot pools that are now known as the Larderello Fields
Technologies in use include dry steam power stations, flash steam power stations and binary cycle
power stations. Geothermal electricity generation is currently used in 24 countries, while geothermal
heating is in use in 70 countries. Geothermal power is considered to be a sustainable, renewable
source of energy because the heat extraction is small compared with the Earth's heat content. The
greenhouse gas emissions of geothermal electric stations are on

Factors Affecting The Biodiversity Of The Lake
Many lakes across the globe are home to a wide variety of organisms, which are supported by both
the lakes themselves and by the abundance of varying habitats surrounding them. Lake Naivasha
(0°45'N, 36°20'E) is one such lake: Situated within the rift valley, Lake Naivasha is a freshwater
home to an abundance of both native and alien flora and fauna, both aquatic and terrestrial
(Otiang'a–Owiti & Oswe, 2007). The lake has 3 main surface inflows; from the Malewa, Gilgil and
Karati rivers, but is an endorheic lake (Otiang'a–Owiti & Oswe, 2007); so is a closed hydrological
system on the surface (Figure 1). Nevertheless, it is thought that water from the lake does move
southward underground, through volcanic rocks (Clarke et al., 1990, Ojiambo et al., 2001). There
are various factors that contribute to the biodiversity of the lake; however one the most predominant
factors is the impact that the steep increase in Naivasha's population has had on the lake. 70% of
Kenya's horticultural output is produced in the Lake Naivasha area (Otiang'a–Owiti & Oswe, 2007),
which makes it an area of extreme national economic importance. Due to this thriving industry, the
lake's population has risen from an estimated 7,000 in the 1969, to approximately 300,000 in 2007
(Ouma Oloo, 2007). This rapid population growth has had effects on many components of the
ecosystem, including changes in lake levels and water composition, loss of habitats, introduction of
alien species and decline in many species

Disadvantages Of Geothermal Energy
Introduction
Over the past several years the realization of a limited amount of renewable resources has pushed
for a more environmentally friendly form of utilities. This realization has shifted the mindset of the
consumer to prefer a more green and economical utility free home using sustainable energy sources.
The scientists at Whole Life Energy are analyzing the use of geothermal energy to meet the
requirements of our consumers and environment. This report covers what geothermal energy is,
different types of geothermal energy, and geothermal energy advantages.
What is Geothermal Energy
Geothermal energy is the routing of liquid filled tubing underneath the Earth's surface to absorb
heat. A small pump is used to circulate the liquid, so the heat can be extracted in the home or
business. "The earth absorbs and stores about half the suns energy. Due to this massive absorption,
the earth maintains a fairly constant temperature of 45–70 degrees Fahrenheit at a depth of 6 feet"
(Rinkesh, 2017). This constant temperature will allow our company to tap into a never–ending
supply of heat production. Depending on the size of facility needing heating will determine the
depth of the tubing required to draw the appropriate energy. The EPA states, "farther below the
surface, the temperature increases at an average rate of approximately 1°F for every 70 feet in
depth" (Renewable Heating and Cooling, 2016). This flexibility allows us the ability to customize
the conditioning

A Brief Look at Geothermal Energy Essay
The power of electricity is available to anyone with a simple click of a button. The methods of
obtaining the energy used to develop that electricity are commonly debated topics. One of those
methods is using geothermal energy, or the Earth's naturally produced heat. There are plenty of
intriguing facts centered upon geothermal energy. For thousands of years, geothermal energy has
been used in some countries for heating and cooking ("Geothermal Energy Info" 2). These
underground systems being used contain water with teperatures that can rise above 200 degrees
Celsius (430 degrees Fahrenheit) ("How Geothermal Energy Works" 2). Italy used geothermal
energy thousands of years ago and is currently the fourth largest producer of geothermal ... Show
These "hot spots" usually occur at thin spots in the Earth's crust or at tectonic plate boundaries
("How Geothermal Energy Works" 2). Water circulates naturally in these seismically active
locations due to the large number of earthquakes in the area. ("How Geothermal Energy Works" 2).
Four forms of producing geothermal energy are currently available: dry steam, wet steam, hot rocks,
and geopressured deposits (Savage 22). To gain access to these resources, cooled water is injected
down a well where it circulates through fractured rocks and heats up. Once hot, the water is sucked
back up to the surface through another to be further processed into energy ("Geothermal Energy" 2).
Dry steam sources are very practical for producing energy due to its very high temperature and its
ability to cause no corrosion to turbines and various types of other equipment involved in the
process (Savage 22). On the other hand, wet steam sources must be regularly maintained because
they do cause damage to the equipment if left unchecked. Despite this drawback, it is a very useful
way to generate energy (Savage 22). "Hot rocks are tantalizing geothermal sources, but water must
be introduced artificially to the dry heat source to produce steam or hot water" (Savage 22).
Geopressured deposits have been exploited for a very long time because they are generally hotter
than most underground water systems (Savage 22). Magma is, without a doubt,

In the coal combustion systems, the coal is burnt at high temperatures. The hot gases and heat
energy that is produced converts water into steam. The steam is passed to a turbine that contains
thousands of blades, when the steam pushes the blades they start to rotate at a high speed. Electricity
is generated when the generator with the wire coils are rotated fast in a strong magnetic field.
Discuss the benefits and limitations
Pros – Geothermal:
Geothermal energy is reliable especially during droughts since it isn't dependent or affected by the
weather conditions
Geothermal energy is generally considered environmentally friendly and does not cause significant
amounts of pollution.
The geothermal reservoirs naturally replenish so therefore it is renewable
The process of creating geothermal energy doesn't involve fuels, which means less cost and stable
electricity prices
Cons – Geothermal:
The extraction of the geothermal energy in steam and hot water needs to be monitored well to avoid
issues like using heat from ground at a higher rate than it is naturally replenished and falling

Persuasive Essay On Geothermal Energy
Geothermal energy is one of the cleanest sources of renewable energy, unlike some other sources of
renewable energy, geothermal energy is contained within a relatively small area, and doesn't affect
local wildlife, it also doesn't produce large amounts of toxic waste, and is nowhere near as
controversial as nuclear power. Unfortunately geothermal energy isn't used nearly as much as many
of the other types of renewable energy, in fact, there are only 12 operating geothermal power plants
in the US, a relatively small number compared to the 557 coal power plants that currently supply the
United States with its second largest source of power. Yet while the fields of solar and wind power
seem to be growing exponentially, geothermal energy remains relatively small.
Sadly the problem with geothermal energy isn't one that can be easily changed. The reason
geothermal power plants are so few and and far between is the overly specific circumstances that are
needed to harness the underground heat; geothermal power plants require hydrological sites with
naturally high temperatures of around 150 to 370, in the form of wells, hot water is then pumped out
of these wells is then pumped out of these wells, into one of three different systems, dry steam, dry
steam, or binary cycle. Dry steam is the simplest, but also the hardest to find. A dry steam system
will pump hot water out of the earth in the form of steam, since the water is already a gas, it can be
injected straight into the turbine

Why is Geothermal Energy Beneficial?
Volcanoes are wondrous formations on the earth. Humans are fascinated by them but are often very
cautious about volcanoes. They see them as explosive, lava spewing mountains often causing natural
disasters. These are just some of the effects of a volcano but plus side to it is that its energy can be
harnessed. Energy that can be used from a volcano is Geothermal Energy. It is a clean, renewable
energy which uses the steam produced from vents and hot springs near volcanoes. In this paper I am
going to prove why Geothermal Energy is good for the environment and the society. Firstly I am
going to discuss what geothermal energy is. Secondly, I will discuss the benefits of geothermal
energy to the environment. Thirdly I am going to show how geothermal energy is beneficial to the
society around its source. Lastly I will compare geothermal energy to other energy sources and show
why geothermal energy is the way to go.
What is Geothermal Energy?
The earth stores thermal energy within itself, this energy is then projected to the surface of the earth.
This is then released through vents that are close to volcanic systems or other tectonically active
areas. These could be steam vents, mud pots and hot springs. The temperatures used to reach up to
100 degrees centigrade. This is the most conventional

The Alternative Source Of Energy
Alternative Source of Energy Over the past years, scientist began thinking deeper into the
possibilities for energy that is renewable. They mostly looked into the sun as there number one
source, the wind and other renewable options. Indeed, the sun for many years has provided heat for
the earth whereby the energy it produces warms the earth directly and also indirectly. By so doing
the heat makes water to evaporate lakes and other water sources like rivers and streams that
eventually falls back to the earth and then filters into the ground. Overview of Geothermal Energy
When we go deep into the history of geothermal energy or rather archeologically, it is clear the first
human use of this discovery was in the North America and this was sometime around 10,000 years
ago with the settlement of the Paleo–Indians near hot springs that served as a source of warmth and
healing purposes. In 1904, Italian scientist, Piero Ginori, the Co Prince Piero Ginori Continti,
established the first geothermal electric power plant in which power was generated by the use of
steam. Ginori is actually the person who is known for the discovery of geothermal energy,
(Armstead, H. C. H. 2008). The three main types of power plant designs, which use geothermal as
the source of energy, are, flash steam, dry steam, and binary–cycle power stations. These sources are
divided into high–temperature resources and low–temperature resources. The preceding two sources
are used for generating heat and

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),

This project presents an adaptive management approach following the Master Plan for Hydro and
Geothermal Energy Resources to assess the environmental effects of hydropower production on
cultural and biological diversity in Iceland. Field data will be collected, comparing current dammed
and non–dammed rivers; looking at landscape well–being and biological diversity of birds, fish,
sheep, pollinators, and vegetation. Data will be continuously collected and evaluated under the
guidelines of the Environmental Impact Post–Assessment. Our framework analyzes the links
between energy development, scientific findings, and communication with stakeholders. It is
necessary to evaluate the economics and environmental impacts of hydropower production in hopes
to promote sustainable development to support society's rapid increase in energy consumption.
Introduction:
Iceland 's mountains, glaciers, rivers, and geothermal hot spots play a major role in sustainable
energy development. Iceland has recognized their natural resources and is utilizing them to create
energy production for their country. Currently, Iceland is generating nearly 100 percent renewable
energy: 73% hydropower, 27% geothermal, and less than one percent fossil fuels (Orkustofnun,
2015). Melting glaciers supply an abundant resource to rivers which Iceland has harnessed to
support hydropower. Hydropower is recognized as a sustainable, clean source of energy. There is
concern that hydropower dams are negatively impacting

The Benefits Of Geothermal Energy
Throughout history, society has been looking for ways to increase renewable energy to provide
better resources to replace fossil fuels to reduce carbon footprints. The earth is a great source of
natural energy therefore thermal energy is one of the most abundant resources. There are many types
of renewable energy, such as sunlight, wind, rain, tides, waves, and geothermal heat. Geothermal
heat renewable energy converts natural heat into electricity resources. Geothermal energy represents
the inner heat of the earth's core. Geothermal energy is mainly produced by decays of radioactive
elements in the mantle and the center of the earth's layers. Heat is constantly flowing from the Earth
center to the surface creating a great source of natural energy. These geothermal power plants drill
wells into geothermal tanks to transfer hot water and steam from the earth's core to the surface. One
great advantage of geothermal energy is that using the resources of water and steam, you are able to
reuse and pump back the supplies into the ground. Another perk of using geothermal energy is that
the energy is clean. Geothermal energy is environmental friendly because the power plants don't use
fossil fuels.
Some of the largest geothermal projects are located in Imperial Valley, California. It has eleven
power plants built near the San Andreas Fault. These power plants are owned and operates by a
company called CalEnergy Operating Corporation and are producing more than seven hundred

Geothermal Energy in America Essay
Sitting under the western half of the United States is a natural source of energy generated by the heat
within the earth itself. When the energy crisis of the 1970's took place, the government began
funding programs to develop methods that would turn the heat produced from geothermal activity
into a tangible source of power. The use of geothermal energy offers a safer alternative to nuclear
power and lessens America's dependence on foreign sources. As a renewable resource, geothermal
energy would offer a stepping stone into lowering the impact Americans left on the environment but
would also allow them to continue the use of the luxuries they had become so accustomed to having.

The DOE creation of State Cooperative Programs lessened the financial burden placed on itself and
the state while developing geothermal energy over the last three decades. The state Cooperative
Programs connected private developers to resources on the local, state and federal level that
produced positive growth in the industry. The addition of research done by universities opened more
geothermal rich regions to exploration and development. Environmental regulations created the
strongest barrier against for the development of geothermal energy. Regulations put into place later
in development caused change to the design of buildings and regulations for disposal for waste
material produced in the process. These challenges created by outside sources became a focus of the
designers who had chosen to develop geothermal energy into a competitive player in the American
energy community. The U.S. Department of Energy Geothermal Technologies Program's report, A

Our cities are growing and so is our rate of power consumption. Luckily for us there is an alternative
to traditional HVAC systems. Geothermal technology uses a piping system (commonly called a
"loop") filled with water installed underground that absorbs the heat from solar energy stored just
below the earth's surface [2]. Geothermal HVAC systems differentiate themselves from common
systems as they do not burn fossil fuel to generate heat [3]. They do, however, use minimal
electricity to power the pump to circulate water through the piping system, but compared to current
HVAC methods three to five units of energy are supplied as heat for every one unit used to power
the system. During the summer the system essentially functions in the opposite manner by absorbing
the heat in your home and transferring it back into the earth [4]. In this report the reader can learn
about the current practices and the alternatives for residential HVAC systems, the technology
limitations of this method and its trends, and a conclusion. Current Practices and Alternatives

Energy : The Causes And Impacts Of Geothermal Energy
Below the Earth's crust, there is a layer of hot and molten rock, called magma. Heat is continually
produced in this layer, mostly from the decay of naturally radioactive materials such as uranium and
potassium. The amount of heat within 10,000 meters (about 33,000 feet) of Earth's surface contains
50,000 times more energy than all the oil and natural gas resources in the world.
The areas with the highest underground temperatures are in regions with active or geologically
young volcanoes. These "hot spots" occur at tectonic plate boundaries or at places where the crust is
thin enough to let the heat through. There is some research that indicates that the steam removal and
water return associated with geothermal plants can trigger minor tectonic events.
The International Geothermal Association (IGA) has reported that 10,715 megawatts (MW) of
geothermal power in 24 countries is online, which is expected to generate 67,246 GWh of electricity
in 2010. This represents a 20% increase in geothermal power online capacity since 2005. IGA
projected this would grow to 18,500 MW by 2015, due to a large number of projects that were under
consideration, often in areas previously assumed to have little exploitable resource.
In Iceland, the Philippines, and El Salvador, geothermal energy accounts for over 25% of national
electricity production.
Canada is the only major country on the Pacific Ring of Fire which has not yet developed
geothermal power. The region of greatest
