The
costs of energy have been increasing since they were first explored
and exploited to fulfill daily needs. Speaking specifically about
crude oil, the use of this limited resource has been increasing in
use and cost in the last several decades, and even quite dramatically
in the last fifteen years or so. People are driving larger, less gas
efficient vehicles, more technology is being produced and need
additional electricity, more people travel via airplane, take
cruises, sail boats, and drive for sport. Not only is the
fundamental source of fuel, crude oil, a limited resource, but it is
also very costly to refine it into a usable substance. The discovery
process for crude oil can be a hit or miss journey. Once a source
has been located, then the drilling begins. The equipment is
expensive and so is the labor. And, as we have seen in recent weeks,
the costs of any and all “accidents” are also financially, and
environmentally, costly.
So
now it has been established that the main source of fuel in the
current world is limited and costly, it is imperative to understand
why the search for an alternative renewable source of energy is
imminent and much needed. Many different sources of renewable energy
have been explored, but none have fully taken root in the United
States. Other countries, such as China, have taken an interest in
some of the technologies discovered and harnessed here in the US.
According to one American business owner “many of these
technologies were invented in the U.S., but they have since migrated
overseas because there has never been much of a market in the U.S.”
(Heim). This could very well be what separates the “thinkers”
and the “doers” in regards to implementing a mainstream renewable
energy source.
According
to the recent Shanghai Expo, China is displaying a very competitive
edge in regards to a clean energy source. “Environmental disasters
and China’s reputation as a prime polluter have driven some of that
urgency” (Heim). China has become the world’s largest consumer
of energy as well as the largest carbon emissions location in the
world. As a result of these facts, China is looking at new ways to
get ahead of the game by investing large sums of money into
eco-friendly renewable energy sources.
One
question many people have is why is a new source of energy needed?
The first thing that comes to mind is that gasoline prices have
skyrocketed in the last several years, which has been costly to many
individuals as well as countries. In addition, crude oil is not a
renewable source of energy. There is only so much oil on earth and
it is being used at a much faster rate than it is being formed. The
question as to whether or not oil has peaked in its supply still
remains uncertain. However, oil is a finite source of energy and
will eventually deplete, so the peak is not as important when making
a decision to find alternative sources of energy. Also, take into
consideration that the current main source of energy is very
environmentally unfriendly. There are many pollutants that are
caused by the current source of energy that can be eliminated if the
primary source of energy is changed (Crump).
There
are many risks associated with the locating, drilling, manufacturing,
and use of crude oil. One of the current media frenzies surrounding
crude oil is the Gulf Coast oil leak. According to CNN, the British
Petroleum (BP) oil spill has released 4.9 million barrels of oil into
the gulf coast region and only 3.3 million gallons have been
recovered. The costs to BP are drastic however the economic impact
to those who reside in this region will suffer more. The entire gulf
coast relies on fishing, crabbing, oysters, recreational tourism, and
other sources of monetary revenue. It is expected for the negative
impact of the oil spill to impact this area for approximately the
next three years. According to studies collected by CNN, the tourism
travel source of revenue is estimated to be $7.6 billion within the
next fifteen months. And we all know that the current oil spill is
only one of the numerous incidents which have placed the environment
at risk as a result of oil spills into natural habitats.
In
searching for a new source of energy there are many factors that must
be requirements. The replacement source of energy must be renewable.
In order for the new source of energy to be a benefit, it must be
able to be renewed and not a finite source. The new main source of
energy must also be eco-friendly. The main reason why a new source
of energy is being searched for is because the source of energy
currently used, crude oil, is harmful to the environment. Looking
for a replacement must have improvements, including being
environmentally friendly. This also means that there must be minimal
or zero pollutants as a result. If the renewable energy creates
byproducts that are harmful to the environment, then it is pointless
and counter productive to utilize that source. The new energy source
must also be effective and reliable. If the new source cannot be
relied upon to be consistent and effective in its delivery, it is not
a viable substitute to what is already being used. And last, but not
least, the replacement source of energy must be cost efficient. Part
of the problem with crude oil is that it is far too costly to
continue to maintain. Not only is it finite in its availability, but
it is also very costly environmentally and financially. The
byproducts created by processing crude oil causes harm to the
environment and the cost of manufacturing the oil and transporting it
harms the pocketbook.
There
are many alternative methods to fuel today’s modern world. Some of
the more popular renewable sources include hydro-electric power, wind
power, all electric power, and solar power. Hydro-electric power
offers a multitude of benefits including cost-efficiency and
eco-friendliness, however not all geographical set-ups have fast
enough running water to utilize this potential resource. Wind fueled
electricity is cost efficient and wind is available all over the
world. However, not all areas are suitable for building wind
turbines on them. Converting to all-electric power requires an
initial power supply. Essentially, switching to an “all-electric”
source of energy requires it to be coupled with another source of
energy in order to make it work. It is far too reliant on another
component. And last but not least, solar power is very popular in
eco-friendly conversations. Solar panels are quite costly in the
onset of setting up solar energy as a renewable source however it
pays off in the long run. Also, there are some areas on the globe
that are not viable places for this type of renewable energy, such as
far north and far south on the globe due to shortened daylight hours
(Withgott & Brennan).
Wind
power utilizes kinetic energy that is then converted into electrical
energy, which can be used as a replacement to nonrenewable sources of
energy. The use of wind power is dramatically increasing across the
world. Germany, the United States, and Spain account for more than
half of the world’s wind energy usage. Denmark is the leader in
wind power output with 20% of power supplies coming directly from
wind turbines. (Withgott & Brennan). Within the US, both
California and Texas produce the majority of wind energy. This could
be because both Texas and California are amongst the top five largest
states as well as financial ability and space to place turbines.
As
wind speeds are significantly greater over water than land, there are
prospects of building wind turbines in the ocean to help maximize the
amount of energy that can be produced and harnessed. Turbulence is
also lessened over water. However, the cost to build and maintain a
turbine in water is much greater than if they were built on land. At
the current time, “offshore wind farms are limited to shallow
water, where towers are sunk into sediments singly or with a tripod
to stabilize them” Withgott & Brennan, p. 368).
As
with many sources of energy, wind power comes with pros and cons. In
order to make an educated decision on whether or not this type of
energy source can provide value and help protect the environment or
not requires people to understand the benefits and detriments. The
people of Atlanta, Georgia, for example, were informed of the pros
and cons regarding wind energy as a viable source and made their
decision based off of the information provided to them. Given the
location of the city, the industrialization of the area, and the lack
of spare fields, Georgians are not yet convinced that wind energy is
a viable solution for them (Keefe). However, there is growing
interest in this area of renewable energy and more research needs to
be conducted to figure out how to make the turbines more efficient
and area friendly.
Wind
has no by-product emissions once the equipment is in place. In
addition, wind power is more efficient than previously relied upon
resources. The return of energy versus the amount of energy that
goes into producing wind energy and harnessing it is much higher,
thus resulting in a higher return rate. It is believed that wind
turbines create 23 times more energy than is consumed to harness that
energy. An economical benefit in favor of wind energy is that those
who own land can lease their property for the use of wind turbines,
thus creating additional personal revenue (Withgott & Brennan).
With
all of the benefits for wind energy, there are some negative avenues
to explore. The main setback for the argument in favor of wind
energy is that wind is not constant. Being that wind is a natural
occurrence, it is impossible to have any control over how often the
wind blows and how hard it blows (Cape Times). If wind used in
conjunction with another type of renewable energy source then this
issue is moot. The second energy source, such as hydrogen fuel for
example, could store the energy that is generated by the wind and
permit it to be ready for use at a later time. Also, some places on
the globe are much windier than others. The Great Plains would have
greater success regarding wind energy than a densely forested area.
In addition, wind turbines can be costly to maintain and repair when
needed. The turbines are subject to damages from birds and bats, as
well as the birds and bats being damaged or even killed by the
turbines (Withgott & Brennan).
“As
a replacement for fossil fuel combustion in the average US utility
generator, the US Environmental Protection Agency has calculated that
running a 1-megawatt wind turbine for 1 year prevents the release of
more than 1,500 tons of carbon dioxide, 6.5 tons of sulfur dioxide,
3.2 tons of nitrogen oxides, and 60 lbs. of mercury” (Withgott &
Brennan). Looking at those numbers alone can sway most to put their
energy into producing wind turbines to replace limited resource
energies.
There
have been many pieces of legislation put forth in encouraging and
discouraging the use of alternative forms of energy. Recently, a law
regarding cleaner energy won over the voters in the city of Aberdeen,
South Dakota. According to the recent article written by Emily
Arthur-Richardt, the city councilmen and women wish to encourage
alternative eco-friendly energy, but they also wish to minimize any
hindrances on the community.
Specifically
speaking, wind turbines would have a height limit and noise
restrictions imposed on them in order to decrease any issues with
property values and inevitable noise pollution. The various areas
surrounding this city would also be zoned for turbines or not, thus
ensuring that not all acreage would be subject to having turbines
built on them. Also, there would be set distances from highly
traveled, highly populated, or frequented areas of the city in order
to maintain safety of its population (Arthur-Richardt). One can
conclude from the actions taken by just one city, the use of wind
turbines to create and harness wind energy is a feasible, viable
solution for an alternative form of renewable energy. With the right
restrictions, planning, and incentives for the people who reside
around them, it is possible to get community members to vote in favor
of wind farms.
In
summary, the only way a renewable form of energy to take root in
modern culture is if the communities impacted are on board. Without
the support of the population, no alternative source of energy will
replace fossil fuels. Changes in how energy is produced and provided
will cost money initially, however the savings will pay off long term
once the preliminary costs are made. Also, there are many arguments
in favor of wind energy as a viable replacement to crude oil, as much
as there are arguments against it. Looking at the totality of
circumstances, it is logical to conclude that the pros outweigh the
cons, thus drawing the conclusion that wind turbines are a cost
efficient replacement to current methodologies.
