In the United States, 42 percent of the nation’s electricity is generated by burning coal as coal is cheap and plentiful.

Clean coal technology usually addresses atmospheric problems resulting from burning coal. Historically, the primary focus was on sulfur dioxide and particulates, since it is the most important gas in the causation of acid rain. More recent focus has been on carbon dioxide (due to its impact on global warming) as well as other pollutants. Concerns exist regarding the economic viability of these technologies and the timeframe of delivery, potentially high hidden economic costs in terms of social and environmental damage, and the costs and viability of disposing of removed carbon and other toxic matter. More, the byproducts of coal power production range from fly ash sludge ponds full of mercury, arsenic, and sulfur in unlined ponds that can leak into the water supply.

I would have to say that from the reading that it can be very harmful for the coal mining chemicals to seep into the ground into our drinking water.

We want instant gratification and coal fits the bill. I noted in my book review of Crude World that Peter Maass didn’t present a balanced picture of the oil industry; it was all bad. He was intended to highlight the negative aspect of our oil dependency. Big Coal is the same in that respect. It is hard to argue that coal hasn’t improved the lives of a great many people around the world, and we know a number of people who would argue that these improvements outweigh the negatives. Further, it is fair to say that the coal industry has come a long way in cleaning up their emission profile over the past few

When I go to my home where I grew up it is all electrical produced and the main producer of that electricity is from coal a fossil fuel. In that area coal is one of the primary exports of that area. (Administration,

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

The production of coal energy produces the most amount of carbon dioxide than any other method. It is a non-renewable energy source, and coal mines destroy most of the surrounding areas around it. With the recession going on, no one is buying into coal power plants at the moment which is an economy issue. (Center for Energy)

Because of technical improvements, nonrenewables are found, extracted, and employed more efficiently than ever. Since 2000, companies have located more natural gas sources in the United States. This occurred because of advances in exploration methods. New ways to process coal have led to fewer impurities. The energy efficiency of coal has also improved so that more energy can be created from less coal.

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

The article, “Coal and the Environment”, provides the readers will and understanding of how coal works and also how it is dangerous to our environment. Coal on its own is not dangerous to the environment but once the coal is burned, then pollutants are released into the air causing for less clean air. The government has taken a stand on the industries polluting the air we breathe in everyday with the Clean Air Act and the Clean Water Act. These two acts put restrictions on industries that allow for safer and cleaner air.

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

Research suggests that coal is an energy source for the future because it is stable and reliable with abundant reserves. Coal is the most affordable and efficient fuel source used to produce power, and because of new technologies, coal can be extracted and used to produce energy more efficiently and cleaner for decades to

Coal is the most abundant and important source of primary energy in the world. There are reserves spread throughout some one hundred countries to meet global needs up to the next two hundred and fifty years. It is the most important fossil fuel for electricity generation and industrial purposes. But, it has pollution issues to the environment like Air pollution, land degradation, noise pollution, etc. But the pollution I am going to be talking about is water pollution from the coal mines in the Alabama rivers.

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.

Coal, a mineral I have discussed previously, is necessary to our everyday lives. Coal is an incredible source of energy; it heats our houses and buildings, and also fuels stoves. You may often wonder where this extremely useful mineral comes from. Coal does not just appear; it needs to be mined through a process which results in our being able to utilize it. Coal mining is fairly inexpensive, is carried out on a large scale and can be mined in either underground or surface mines.
