Disadvantages Of Coal Energy

Clean coal is proposed as being an emission cleaner form of regular coal, because it reduces the amount of sulfur-dioxide, and nitrogen oxide that is produced by burning coal. It does this by removing impurities from the coal that are contributing to the higher emissions within regular coal, which is created through “clean coal technology”. Clean coal is obtained just like regular coal through either mining it or by mountaintop removal. A technique called coal washing is used to remove impurities, such as sulfur and other unwanted minerals, by washing them in a liquid to remove them.

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

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 (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.

Many places are known for many things, and West Virginia is known for its coal. As much as a television remote needs batteries, West Virginia needed coal in its early statehood. Coal has recently been the subject of chaos in many circles around the state. Many believe we should bleed, breathe, and breed coal. While others realize that coal is dangerous and is on its way out the door. As everything else in the world coal has its Pro's and Con's. For example, coal is a cheaper alternative to creating heat which maintains electricity. Though you may pollute the air with a high concentrate of sulfur in which coal releases. As for me, I believe coal is on its deathbed and rightfully so. Coal has taken far too many lives, such, as young men, grandfathers,

In the matter of clean -coal technologies, illustrates the pros and cons of whether or not "clean coal" technologies are benefiting or still causing harm to the environment.

Coal is a type of energy source that we use a lot of to make heat and energy. It is made up of mostly carbon and also includes other elements like hydrogen, oxygen, sulphur and nitrogen. It is a non-renewable source because it takes millions of years to form. Coal is the world’s largest source of energy for the production of electricity and the use of it is increasing every year. E.g. in 2006 the world consumed over 6,000,000,000,000 Kg of coal.

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?

Most of the electricity around the world comes from burning fossil fuel such as coal, natural gas and oil. According to the U.S. Department of Energy, nearly half of the electricity used in the U.S comes from burning coal; in America, coal is mined in 26 out 50 states making coal the most abundant and cost the lowest to generate electricity. Although cheap, it is controversial to keep mining coal because it is destroying about environment. Mining coal disrupts the surround land, contaminates the water, and pollutes the air.

With that being said here are some environmental impacts of coal you may not know about. The air pollutants cause acid rain, smog ,respiratory illnesses, cancers and toxins in the environment. Coal miners can get respiratory illnesses from the coal dust while mining. If an abandoned coal mine catches fire it puts tons of mercury into the atmosphere, this happens every year and is responsible for three percent of carbon dioxide emissions globally. The second largest contributor to

Coal is not the most abundant fossil fuel, and should not be used in the future. There are three main reasons for this, the first being that the amount of coal in the world is very close to gone. Every year, humans consume 11 billion tons of coal a year, scientists predict that the coal supply will be gone in the next 50 years (Ecotricity, 2017). Another being that coal not being a major source of energy, it is a dirty and hazardous organic matter. Coal can cause black lung disease for the miners who are harvesting the coal (Chiras, 2016). The last major reason is that burning coal is a major source of pollution for the atmosphere. The impact that coal has on the environment is detrimental. When coal is being mined it is mined by using a technique

Coal is a solid energy source, but the only issue about coal fired power is it has a large impact on the environment. There is an estimated amount of 892 billion tonnes of coal reserves worldwide. This amount of coal should be able to last us approximately 110 years at our current rates of production.

Coal is a nonrenewable energy source, meaning that there is a limited supply of it and therefore if too much is expended the source will eventually run out. There are three primary advantages associated with the production and use of coal energy, abundance, affordability, and capital maintenance. Coal is a relatively inexpensive fossil fuel; this may be because of the great abundance of it with it being a fairly predictable and a reliable source. This abundance leads to low and stable prices, with a relative simplistic conversion of coal to energy, resulting in power generation plants being built using less governmental faculties compared to many other competing energy sources. Such advantages make coal a popular energy source globally, especially

Wind energy is safer for the environment versus burning coal because of the benefits wind energy provides. For example, wind energy does not emit any CO2 , and it has no ongoing fuel costs. Wind energy does not involve removing minerals and nutrients from the earth as does strip mining. Nor does wind energy contaminate ground water. Wind energy does not emit any airborne mercury. In addition, the burning of coal releases toxic fumes into the atmosphere and produces about 200 pounds of carbon dioxide per kilowatt of energy generated. This is very harmful to plants, animals, and the air we breathe. Wind energy is a renewable source of energy, whereas coal is a non-renewable fuel source.
