Impact of Coal vs Uranium Power Plants
Currently our country, and especially California, is confronting a serious energy crisis. Newspaper headlines warn of blackouts and tremendous rate increases. The cost of all we buy will increase in an effort to cover the added expenses. They only way to control this shortage of fuel are to produce more, conserve and control the amount of energy we use or a combination of conserving and increasing production.
In the United States two major sources of energy are coal and nuclear power. There are coal power plants and nuclear power plants. Both of them were built for the same purpose, to supply energy to the world. Some would say that coal is better, more efficient and safer than nuclear power. But then again, many people believe that nuclear power is the power of the future and what we are going to be relying on. Both sides have their pros and cons, making it hard to determine which one is safer, cleaner, more efficient, and in greatest supply.
Coal is a natural resource of Earth. “Coal is a combustible, sedimentary, organic rock (composed primarily of carbon, hydrogen and oxygen) formed from vegetation.” “Large coal deposits only started to be formed after the evolution of land plants in the Devonian period, some four hundred million years ago.” (The Origin) Vegetation was consolidated between other rock strata forming coal seams. Then the vegetation was “altered by the combined effects of microbial action, pressure and heat over a considerable time period.”(What is Coal)
The altered remains of prehistoric vegetation originally accumulated as plant material in swamps and peat bogs. “The accumulation of silt and other sediments, together with movements in the earth’s crust ...

There are many sources of energy today, and the best source of it is constantly being sought after, one source stands out above the rest. Nuclear energy is simple in theory, yet it may be one of the most controversial sources of power. Nuclear energy works using reactors built to split the atoms (nuclear fission) of the fuel to produce heat. This heat evaporates the cooling agent (usually water) into steam which turns turbines to create electricity. Nuclear energy should be allowed, because it produces an abundance of electricity, as well as being a clean source of energy with no harmful emissions. Nuclear energy is the future of clean, environmentally friendly energy.
...nce World War II to the present day, the technology of nuclear power has increased significantly in terms of energy output and safety. The energy efficiency of nuclear power is far superior to its counterpart fossil fuel and renewable energy. Compared to fossil fuels, tiny amounts of fuel used by nuclear reactors is equivalent to a large sum of coal. This is a no brainer. Why mine a ton of coal when a little uranium can be used to gain the same amount of energy? Not only is it efficient, it’s safe to use. Used fuel is packed away in storage safely, so there isn’t any chance of radiation leaking out. In the present day, nuclear power incidents haven’t been occurring lately. Advancements in technology and equipment used have made nuclear energy a very reliable and safe source of energy. With today’s energy needs, nuclear power has the ability to keep up in the race.
The purpose of this report is to investigate the different views and opinions on the safeness and cost effectiveness of nuclear power compared to other forms of energy. This report will explain the issues and background of the debate, the importance of the issue, and the parties who are involved in this debate with their thoughts.
Media coverage of such cases have made the public less comfortable with the idea of moving further towards nuclear power and they only opt for reducing human activities to reduce global warming. It is true that there have been some notable disasters involving nuclear power, but compared to other power systems, nuclear power has an impressive track record. First, it is less harmful and second, it will be able to cater for the growing world population. Nuclear power produces clean energy and it delivers it at a cost that is competitive in the energy market (Patterson). According to the US Energy Information Administration, there are currently 65 such plants in the Unite States (National Research Council). They produce 19 percent of the total US energy generation.
Coal is one of the world’s most abundant fossil fuels. Coal was formed during the Carboniferous Period when dead plant material was buried and subjected to high pressure and heat. Coal is classified by moisture content and composition. There are four d...
How coal is formed is quite an interesting topic. It started over millions of years ago in ancient swamps when vegetation and trees died and formed peat (it is where vegetation builds up and turns into a super messy pile of stuff). This peat was eventually covered with either dirt or sand. As the peat is covered and pressure the gas that the peat gives off starts to get trapped in the new forming coal. Several years the peat now turns to rock known as coal. As the planetary plates shift the coal moves and forms pockets and runs in the earth. Then people came along and found out how to harness is power. People had to get the coal out of the earth. One way they found out how to get it out was to dig it out of the underground tunnels to find where the coal runs. Another way to get the coal is to strip mine the coal this is where the miners remove huge amounts of dirt to get to the coal. Both of these mining techniques are extremely dangers.
Coal is formed from remains of vegetation that grew hundreds of millions of years ago. A majority of our coal was formed about 300 million years ago. During this time, most of the earth was covered with steamy swamps. As time passed, the remains of dead plants and trees sank to the bottom of these swamps. These layers of dead plant remains eventually become a dense and soggy substance known as peat. Throughout time, seas and rivers allowed sand, clay, and other mineral deposits to layer upon the peat. The increase of this process eventually caused the substance to form into coal.
Coal has a very negative impact on the environment, one of the main impacts on the environment is the actual process of extracting the coal from the ground. The two ways that coal is mined, underground and surface, both have different effects on the environment. The first way that coal is mined is by digging tunnels and creating mineshafts underground and then removing the coal from th...
Nuclear power plants are known as good sources of energy but they have their cons. Nuclear power plants are used around the world as a source of energy. These power plants work by using a process called fission. Fission is the process of splitting an atom of uranium like in the atomic bomb dropped on Hiroshima and Nagasaki. This process only produces steam which is harmless to the environment. The one problem is that they create nuclear waste. Nuclear waste is still radioactive and hard to dispose it. Another problem is that the uranium used in them is nonrenewable. This means that once there is no more, there will be no more nuclear energy. Also an accident caused by these power plants release waves of radiation that are very harmful to
Nuclear energy has been identified as an effective source of electrical power that is being capitalized upon around the world. While nuclear power offers benefits, such as sustainable energy, the risks associated with it including nuclear accidents, proliferation, and terrorism make it a gamble. The probability of such events occurring is low, but the impact they could cause is immense. However, the irreversible effects of climate change override the concerns with nuclear power which can be alleviated by heightened security and international efforts.
Natural gas and coal – there are many ongoing debates about the sustainability of the two for future fuel sources. Coal mining has had a negative connotation for many years. Many people have worked their entire lives in the coal mining industry - only to end up in debt and be diagnosed with black lung. With natural gas, there is concern over having enough supply, or are the switching costs from coal to natural gas power plants or from gasoline to natural gas fueled automobiles worth the investment? In ways, coal and natural gas are almost competing fuels, in a race to find which one will take the winner in the future energy market for electricity generation. Which one is more sustainable and economically
So, what is coal? Coal is a fossil fuel and is the altered remains of prehistoric vegetation and organisms that originally accumulated in swamps and peat bogs. The energy we get from coal today comes from the energy that plants absorbed from the sun millions of years ago.
The use of nuclear power in the mid-1980s was not a popular idea on account of all the fears that it had presented. The public seemed to have rejected it because of the fear of radiation. The Chernobyl accident in the Soviet Union in April of 1986 reinforced the fears, and gave them an international dimension (Cohen 1). Nevertheless, the public has to come to terms that one of the major requirements for sustaining human progress is an adequate source of energy. The current largest sources of energy are the combustion of coal, oil, and natural gas. Fear of radiation may push nuclear power under the carpet but another fear of the unknown is how costly is this going to be? If we as the public have to overcome the fear of radiation and costly project, we first have to understand the details of nuclear energy. The known is a lot less scary then the unknown. If we could put away all the presumptions we have about this new energy source, then maybe we can understand that this would be a good decision for use in the near future.
There are three types of fossil fuels- coal, crude oil, and natural gas. Coal was formed very slowly. Even the “newest” coal we use today was formed a million years ago. Most of the coal we use was formed 300 million years ago, when the Earth was covered with swamps. When plants and trees died, they sank to the bottoms of the swamps. These plants and trees were layered on top of each other, forming a substance called peat. Peat is considered the first stage in coal formation. It is a mixture of water, leaves, braches, and other plant debris. Over time, the Earth changed, and deposits of sand, clay, and other minerals were formed, burying the peat. Sedimentary rock...
