These days, most of us tend to take electricity for granted. If one were to be asked where it comes from, you would most likely get responses from all over, with a common response being, “Out of the sockets in the wall!” In this paper I will be giving a very brief overview of how electricity is produced, specifically from coal.
They are the similar because they both produce energy they both make at least 1 type of energy, wind makes electricity and coal makes electricity generation. Coal and wind energy have been around for a long time, lots of people use coal and wind energy a lot for electricity and electricity generation.
The pollution is leaving our footprint rate out of control! Knowing that they have gotten rid of all the coal generators is a big reduction of the ecological footprint. Without the generators burning off the coal, the pollution will stay at a lower rate causing the footprint to decrease. It is more sustainable now than before because our city doesn't have to worry about trying to maintain the pollution levels as much as we used to and we can focus on more of the major projects.
Nowadays, coal is still one of the greatest used energy to generate power in so many countries. Using coal in electricity generation is 93% in South African, 87% in Poland, 79% in China, 78% in Australia, 45% in USA, 41% in Germany, 58% in Israel etc. (Coal & Electricity) From the data above, even the developed countries use coal to generate power as the main source. In many developed countries, energy generation is still based on coal as a long-term source. In recent years, although there is an increasing number of equipment using gas and wind to generate the power, it is still lower than the proportion of coal-fired power generation. The reason why most countries choose coal as a main source to generate electricity, is that there are many advantages in using coal to generate electricity. First of all, coal is the
My Aunt, Janice James, lived on the most beautiful piece of land in Knoxville, Tennessee, on the Emory River. You could see why she and her husband chose to live here for so many years, it was picturesque. It was picturesque until December of 2008 when the TVA’s Kingston Fossil Plant led to the biggest coal-ash spill in history. TVA uses coal to develop ‘cleaner’ electricity for the communities surrounding. They may claim to have bettered the community, but years later, it is still devastating that Janice James lost her home and will never be able to visit the gorgeous piece of land she called home for so long. This event was one of the biggest tragedies Janice had faced, but she was able to move on and find another
Coal contains a lot of energy and is abundant. Next, the technological demands are low, as well as the cost. It is easy to manage and needs little purification before
Coal’s reputation has become as black as coal itself, but without it the quality of life that hundreds of millions of people enjoy today would not be possible. Coal has been used in many ways throughout history and it will continue to be a vital resource in supplying the energy needed to fuel an energy hungry world. Research cited throughout this paper suggests that coal is an energy source for the future because it is stable and reliable with abundant reserves, it is the most affordable and efficient fuel source used to produce power, and because of new clean coal technologies, coal can be burned with minimal to no damage to the environment.
Coal is currently one of the world’s largest sources of energy. There are different types of coal which are peat, lignite, bituminous and anthracite. Brown coal (lignite) is a combustible sedimentary rock that is found in the layers under the earth. Brown coal is the lowest grade of coal and is soft due to the water content. Since brown coal is high in moisture and is combustive, it was uneconomical to transport, but currently available drying techniques makes it easier to transport. A question that has been raised over the years is whether power stations which use brown coal should be closed.
powerplants usually add chlorine or other harmful chemicals to the water they use, which means that these chemicals also get released back into the environment. Another negative impact is the amount of energy being created. Most of heat used for burning the coal and creating steam is wasted. Coal powerplants usually only use 33 – 35% of the coals heat to create electricity. The rest of the heat gets released into the atmosphere or absorbed by cooling water. This is negative as this sudden influx of heat could affect the climate in that area, if not the world. If we have millions of coal power plants (Keep in mind it produces 41% of the electricity) than whats not to say all that heat and other emission from the plants won’t cause global warming?
The next step in making clean coal more widely accepted is for people to see its effects in action. Personally, I would perform an on-site demonstration in the community of Brandywine, Maryland. If any community deserves be the first to reap the potential benefits of clean coal it’s Brandywine. Currently, there are five coal burning power plants operating in the low income area, which is predominantly populated by African-Americans. This would also coincide with the urgency of the civil rights complaint that various environmental groups have filed against the state of Maryland for permitting the construction of so many gas-fired power plants that contribute to the overall environmental pollution of the community and the deteriorating health
People use energy a lot, especially these energy's coal and wind. Do you know a lot about the 2 energies? Their used to be a Windmill that makes water but now they invented Wind Turbines for electricity. Coal is also called dirty energy and 27 states mine
Lignite is the lowest rank of coal with the lowest energy content. Lignite coal deposits tend to be relatively young coal deposits that were not subjected to extreme heat or pressure, containing 25%-35% carbon. Lignite is crumbly and has high moisture content. There are 19 lignite mines in the United States, producing about 7% of U.S. coal.
In the matter of clean-coal technologies, Alex supported his position better. His information was all relevant to the discussion and his reasoning was sound and free of fallacies.
The idea of burning coal, is not a new one, nor is it recent that coal has been chosen as a fuel source since the 1700’s in England as it burned hotter and cleaner than anything else at the time, which caused it to find its way into steam
