The Pros and Cons of Fossil Fuels
http://www.buzzle.com/articles/fossil-fuels-pros-and-cons.html
Arguments in Favor of Fossil Fuels
The main reason behind the immense popularity of fossil fuels, as energy
source, is that each of them have a high calorific value. In other
words, combustion of fossil fuels generates a large amount of usable
energy and are considered as high efficiency fuels. In spite of being
such a highly combustible material, fossil fuels are quite stable in
nature as compared to many other forms of fuels.
Another advantage is their availability. The fuels can be found quite
easily on the surface of the earth. Moreover, the extraction and
refining processes are not very time-consuming and hence, the crude form
of these fuels can be easily converted for practical purposes.
Almost fifty percent of the power generation plants of the United States
utilize coal as the source of fuel. This is because, it is cheap and is
a highly reliable source of energy.
As coal can be transported from one place to another without any
hassles, it is not necessary to build the power stations close to the
location of the coal mines. Whereas, oil and natural gas have one big
advantage that they can be carried very easily by the means of
pipelines.
Last but not the least, it helps to create job opportunities for people.
This is an important aspect of fossil fuels that we cannot afford to
ignore. It generates employment for millions of people all across the
globe who are involved with processing of the fossil fuels in one way or
the other.
Arguments Against Fossil Fuels
When fossil fuels are burned, a large amount of carbon dioxide is
released. Carbon dioxide is considered as one of the greenhouse gases.
In the atmosphere, it absorbs heat and contributes towards the green
house effect. As the percentage of carbon in the atmosphere becomes
high, it leads to elevation in the average temperature on the earth.
This is known as global warming and it has several adverse effects on
our environment.
Another toxic gas released by fossil fuels is sulfur dioxide, which
reacts with the moisture present in air to produce sulfuric acid. This
leads to acid rain which causes extensive damage to the living as well
as nonliving matter on the earth.
The coal mines are full of various harmful gases and they pose a threat
to the lives of thousands of miners working in them. Some of the by
products obtained during processing of the fossil fuels are highly toxic
too. Oil is often transported from one place to another by the means of
sea route. During this time, oil spills occur on the ocean surface and
that causes severe harm to the marine life.
Due to mining of the coalfields, landscapes spread over large areas is
being destroyed and the land surface cannot be used for any other
purpose. Search for newer location for oil reserves is an highly
expensive process with a very low success rate. As a result, huge amount
of money gets wasted in the process.
Fossil fuels are non-renewable source of energy and are being used up
very fast. As a result, there will be more demand and less supply of
fossil fuels in future. This is likely to increase the price of fossil
fuels manifold.
Depletion of these non-renewable sources of energy is taking place at a
rapid pace because of the increasing demands of energy, with the
modernization of our society. However, the time required for production
of fossil fuels is millions of years. So, there is not enough scope to
renew the sources of fossil fuels. Therefore, it is high time that we
start looking out for some renewable sources of energy that can be used
as an alternative to fossil fuels.
By Bidisha Mukherjee
Though fossil fuel is technically a renewable source of energy, but the time required to produce fossil fuel is too long to be used again within several generations. Fossil fuel is still the most popular source of energy today because power plants are relatively cheap to produce and the energy made from fossil fuels is high enough to be quite cost effective. The major problem of fossil fuel is the pollution of carbon dioxide that is released from using it. The pollution due to the use of fossil fuel is one of the causes of global warming. Since fossil fuel would be mined out in approximately 50 years, we must find another energy source to replace it.
