The Fossil Fuel Coal Essay

1 What is coal? Coal is a substance we consider today a fossil fuel, created from all the dead plants millions of years ago. Coal is formed from prehistoric plants that when they die are not able to release the energy they built up from photosynthesis Typically the plants had fallen into large swamps and bogs, and then over time the dead plants lying on the bottom of the swamps and bogs were slowly covered with other dead plants and sediment build-up. Once buried the plants were subjected to high amounts of pressure and temperatures, which over long periods of time it becomes peat then eventually creates coal. We refer to coal as a “fossil fuel” today because it is created from prehistoric plants and the coal we have today has been millions of years since it was in plant form. Today we coal is still being created we just don’t fully recognize it because how long the process actually takes.

Coal is the dirtiest of all fossil fuels. When burned, it produces emissions that contribute to global warming, create acid rain and pollute water. With all of the talk surrounding nuclear energy, hydropower and biofuels, you might be forgiven for thinking that grimy coal is finally on its way out. On the other hand, coal is no sooty remnant of the Industrial Revolution - it generates half of the electricity in the United States and will likely continue to do so as long as it's cheap and plentiful . Clean coal technology seeks to reduce harsh environmental effects by using multiple technologies to clean. Coal is a fossil fuel composed primarily of carbons and hydrocarbons. Its ingredients help make plastics, tar and fertilizers. A coal derivative, a solidified carbon called coke, melts iron ore and reduces it to create steel. But most coal - 92 percent of the U.S. supply - goes into power production .Electric companies and businesses with power plants burn coal to make the steam that turns turbines and generates electricity. When coal burns, it releases carbon dioxide and other emissions in flue gas, the billowing clouds you see pouring out of smoke stacks. Some clean coal technologies purify the coal before it burns. One type of coal preparation, coal washing, removes unwanted minerals by mixing crushed coal with a liquid and allowing the impurities to separate and settle. Other systems control the coal burn to minimize emissions of sulfur dioxide, nitrogen oxides and

The energy we get from coal today comes from the energy that plants absorbed from the sun millions of years ago. When an area is to be mined, topsoil and subsoil are removed from the rock and so is another material, call overburden, to expose the bed of coal. All living plants give solar energy through photosynthesis. When plants die the energy gets out as the plants decay. The whole decaying process gets interrupted which prevents the release of the stored solar energy, then the energy stays locked in the coal. The plant material gets subjected to high temperatures and pressures which causes physical and chemical changes in the vegetation, transforming it into peat and then into coal. The formation of peat is the first step in the geological formation of fossil fuels such as coal. Peat plants is not only the first step for formation but they also capture CO2 itself. There are many effect to the environment when it comes to coal; an example is AMD which stands for Acid mine drainage; it includes the outflow of acidic water from coal mines or metal mines. Mines exposed rocks containing pyrite which reacts to water and air to form acid and dissolved iron and can easily wash into rivers and streams. Coal is a huge impact when it comes to hurting our

Coal has been around for 250 million years, but only has been used since the 1800’s first by trains and now for energy all around the world and many other things that people couldn't think of! Coal is a combustible sedimentary organic rock which is composed of carbon, hydrogen, and oxygen. It is formed from vegetation which has been consolidated between two other rock strata and altered by the combined effects of pressure and heat over millions of years to form coal seams. There are over 174,000 jobs in the U.S associated with coal and 83,000 of them are mining jobs, Coal miners have found many ways to extract coal from the ground which includes, surface mining, longwall mining, room and pillar mining, and underground mining. “Surface

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 (n): A combustible black or dark brown rock consisting mainly of carbonized plant matter, found mainly in underground deposits and widely used as fuel. This little rock is what keeps 39% of our nation running. 10% of that coal comes from stripping the Appalachian mountain range of her beautiful peaks in a process called strip mining- or, more popularly, Mountaintop Removal. Coal is considered a non-renewable energy resource, meaning once it’s depleted, it will not return for millions of years. Once it's gone, it's gone. These non-renewable sources are found deep underground. Coal needs to be mined out, either by machine or by manual labor. The use of and the process in which we procure coal is a detriment to both the environment and the people in said environment. It is dangerous to the workers within the mines, the flora and fauna around the sites, and the surrounding communities.

Humans have severely depleted them in just over one hundred years, a rate that is 50 million times greater than the rate at which they are formed. The three primary types of fossil fuels are: coal, oil, and natural gas. Coal is a hard, black substance found close to the earth's surface or mined from deep in the ground. There are over two thousand mines in the United States from which more than eight hundred thousand tons of coal are removed each year, supplying approximately 1,566 coal-burning electric power plants. Coal is responsible for providing much of the energy for producing electricity. In fact, there are currently ninety-four new coal-burning power plants that have been proposed, which would power approximately 62 million homes. Oil could be considered a liquid version of coal. It is usually black, but it can also be dark green or even almost clear. Oil is often found underground in spaces directly above coal deposits. Different types of fuels, also called petroleum, are made from oil, which come in different thicknesses. Dissolved gases make up the thinnest oils while asphalt oil is regarded as the

To begin, coal is a combustible black rock which consist mainly is carbonized plant matter, and it found mostly in underground deposits and it is widely used for fuel. As time went on we could see the advantages of coal however, gradually we could see the disadvantages. One advantage of coal is that I can easily burn therefore making it easier to produce more quick energy. Another advantage would be that coal energy is affordable due to its stable price unlike other different energy producers. However, on the opposite side there are many disadvantages. For one, coal energy is depleting rapidly because many people consume large amounts of it daily. Also, the process in which it is obtained is very dangerous. Situations like cave-ins and explosion could and have occurred while men were mining.

In how many ways can coal impact the environment? Coal is a type of rock that consists of plant matter, and it is one of the two fossil fuels. It is transferred into energy by the powder being burned, then the heat turns the water into steam and the high pressure heat turns a turbine, which is connected to a generator. Coal energy impacts the environment by, providing jobs, a stable energy source, and the pollution it gives off.

Coal is a non-renewable resource that we use to power different things from houses to trains and get our electricity from. In order to convert coal into electricity there are multiple steps in which your have to take. First, you have to mix ground coal with hot air which is then transferred into a furnace. A furnace is an inclosed area in which materials can be heated to a very high temperature inside of the furnace. The hot air and ground up coal will then heat a boiler which contains water inside of it. A boiler is basically a container that is used for heating water to high temperatures like pans that boil water. The water then condenses into water vapor or steam from the hot air and coals heating the boiler. The steam then turns a turbine

Coal is a hard, black colored rock-like substance. It is made up of carbon, hydrogen, nitrogen, and varying amount of sulphur. Coal was form as decomposition took place in the absence of oxygen and much of the hydrogen content of the matter was eroded away, leaving a material rich in carbon. The material was compressed over the years by sand and dirt, leaving the form of a carbon known as coal. The different types of coals are Anthracite, bituminous, lignite, peat, coke, and charcoal. Coal is mined out of the ground and used to produce energy. However, they are many deaths, injuries, and sickness involved in mining coal.

After the coal has been removed form the earth, it is still not ready for use; it must first be refined. Coal must first be separated form foreign materials, for example other minerals, to be considered useful to us. One way of doing this is called coal washing. The coal is first crushed into smaller pieces, and then a liquid is used to separate the coal based on density. Coal that is higher in density harbors more ash, so is left behind, whereas low-density coal has contains little ash and is more desirable. Another process to separate coal from foreign materials is call dry-shaling, which works without the use of liquid. After being separated, coal can be processed into coke, and eventually steel. When coal is transported, it can be by means of truck, train, or ship, and can go nearly anywhere. Truck and train transportation are the cheapest forms, particularly train if you are shipping a great amount, and ships are used for overseas transport.

CO2 is the most significant greenhouse gas, which mainly comes from the use of fossil fuels. Many people feel that content of CO2 in the atmosphere is the main reason for manmade global warming. The main sources of CO2 emissions involve electricity generation, industrial processes, fumes from transportation and commercial buildings and use. Emissions of greenhouse gases, such as CO2, to the atmosphere are expected to cause even more of a significant change in global climate (Davison, 2007). The main focus to try to reduce the amount of carbon dioxide in the atmosphere is to reduce the amount that is released from coal-fired power plants. Greenhouse gas emissions that involve the productions of electricity come from natural gas production and coal-fired power plant operations. Natural gas production accounts for twenty-four percent and coal-fired power plant operations accounts for seventy-five percent, while the other one percent is caused by other electricity generation operations. The main reason why coal-fired power plants have a higher percentage of emissions is because the sulfur content of coal is much higher than that of other fossil fuels (Jarmaillo et al., 2007). This proves that there is a great need to find an alternative fossil fuel to use instead of coal. Although coal is easy to mine, transport and process for the electricity generation process, it is also the

Lignite is the softest coal. Further compression and aging caused the lignite coal to change into bituminous coal. Bituminous is a soft, black, brittle material that is extremely flammable and produces a lot of ash and sulfur when burned. This is the type of coal that is mined in the Appalachian Mountains, Great Plains, and the Colorado Plateau. Heat and pressure then turn bituminous into anthracite. Anthracite is the final stage of coal, and is composed almost entirely of carbon. Lignite and bituminous coal are sedimentary, while anthracite is metamorphic. Anthracite is only found where pressure and heat were very great. It doesn’t produce as much heat as bituminous coal, but it burns longer without as much residue. There are anthracite fields in Pennsylvania and Great Britain (U.S Energy Information Administration).
