Burning of coal, a fossil fuel is one of the principal causes ofclimate change and global warming. "Clean coal" or "Green coal" is a theory that we can captureall the pollutants including sulphur dioxide and carbon dioxidefrom coal as it is burnt and store them, instead of releasing themas greenh…ouse gases. The carbon dioxide will then be pumped underground into vacantspaces where oil and natural gas used to be. This will be known as" carbon sequestration ". Countries that rely on coal for their economies and electricitygeneration (Australia, for one) are hoping that clean coal will letthem continue using and exporting "clean" coal without the carbonpollution attached. Unfortunately there are no examples of successful coal "cleaning"so far. Many environmentalists believe that the term clean coal ismisleading: "There is no such thing as 'clean coal' and there neverwill be. It's an oxymoron" (Sierra Club director, Dan Becker). Complaints are: . Coal mining has a high environmental impact . Carbon Sequestration costs will be extremely high . There is no sure science on how to capture or store thepollutants. A: Clean coal is essentially a lie made up by politicians to foolvoters into believing the government is acting on the energycrisis. In the real coal industry, "clean coal" has beenimplemented in 6% of coal-power stations, and is now no longerbeing used in any stations. The chemistry behind clean coalproduces highly toxic chemicals as a by-product, and hence cannotbe used to fix the energy crisis. It certainly isn't good for theenvironment. As an example of the difficulties involved, Australia's coal-firedpower stations produce 260 trillion liters of carbon dioxide every day (260,000,000,000 liters). The energy required tocompress and sequester this would use massive amounts of the powergenerated by the "cleaned" coal. Clean coal is a term for technology (Clean coal technology) thatmitigates emissions of carbon dioxide (CO2) and other greenhousegasses that arise from the burning of coal for electrical power. Itreduces the harmful emissions caused by the burning of fossilfuels. coal that is burned with technology that cuts the amount ofsoot and sulfur dioxide emitted . ( Full Answer )
Coal is obtained by strip mining which removes all soil above a coal deposit. The soil is replaced but it takes many years for the ecosystem to recover and there are four ranks of coal which are: . lignite . sub-bituminous . bituminous . anthracite
The countries that produce & export the most coal is: 1.China 2.USA 3.European Union 4.India 5.Australia 6.Russia 7.South Africa 8.Indonesia 9.Germany 10.Poland
Plants and animals that lived in the ancient, geological past and have become buried in the Earth's rocks as they were deposited.
There are a number of synthetic sources that plastic could bereplaced with if petroleum and coal were exhausted. These sourcesare being invented and created right now.
Coal is mined by two methods: surface or 'opencast' mining or underground or 'deep' mining. The choice of mining method largely depends on the geology of thecoal deposit. Underground mining currently accounts for a biggershare of world coal production than opencast; although in severalimportant co…al producing countries surface mining is morecommon. ( Full Answer )
Coal originated from ancient plants that flourished in swamp-like environments millions of years ago. In Virginia, coal was formed mainly during the Carboniferous period of the Earth's history, 280 to 360 million years ago. There are also coalbeds in Virginia that were formed during the Triassic p…eriod, 205 to 245 million years ago. By comparison, most of the coals in the western U.S. were formed during the Cretaceous period, 70 to 140 million years ago, and the Tertiary period, 2 to 70 million years ago. ( Full Answer )
Coal is a combustible solid. When it is heated to a high enough temperature, it combines with oxygen in the air. giving off heat and waste gasses.

Coal refining is nowhere near as complex as oil refining. Coal is washed with a water or chemical bath to remove some impurities. As much as 30 percent of the sulfur can be removed by washing. At the power plant, coal is pulverized to a heavy powder just before being burned. From http://www.ucsusa….org/clean_energy/coalvswind/brief_coal.html ( Full Answer )
No one invented coal it was discovered. It is dead animals/trees who have been under alot of pressure for millions of years and formed coal
it will produce pollution then eventually affect living things habitat that will cause food chain problems too.
There are three major forms of fossil fuels , Coal, Oil and natural gas. All three were formed many hundreds of millions of years ago before the time of the dinosaurs - hence the name fossil fuels. The age they were formed is called the Carboniferous period. It was part of the Paleozoic Era. Carboni…ferous gets its name from carbon, the basic element in coal and other fossil fuels.. The carboniferous period occurred from about 360 to 286 million years ago. At the time, the land was covered with swamps filled with huge trees, ferns and other large leafy plants. The water and seas were filled with algae - the green stuff that forms on a stagnant pool of water. Algae is actually millions of very small plants. Some deposits of coal can be found during the time of the dinosaurs. As the trees and plants died, they sank to the bottom of the swamps of oceans. They formed layers of spongy material called peat. Over many hundreds of years, the peat was covered by sand and clay and other minerals, which turned into a type of rock called sedimentary.. More and More rock piled on top of more rock, ( Full Answer )
coal in depth of earth formed by trees which were buried over thousands of years ago may be due to some natural disaster , and as we know earth depth is warm , and trees converted to coal .
Scientists believe that during the Carboniferous period (280 to 345 million years ago) large amounts of plant life and other organic matter grew in the swampy areas and lagoons that covered much of the earth. As the plants and other life forms died, they drifted down to the bottom of the swamps, slo…wly decomposed, and formed Peat - a soggy, sponge like material. The peat became buried and compressed under the earth's surfaces over a long period of time. Over millions of years and through the forces of heat and pressure, the compressed peat became coal. The greater the heat and pressure, the harder the coal was that formed. (Source: http://www.teachcoal.org/aboutcoal/articles/faqs.html) One of the largest coal reserves in the United States is in Northern Pennsylvania. You can also find many active coal mines is West Virginia as well. The United States has the largest world reserve of Coal, While China is the largest extractor of Coal. ( Full Answer )
i think its from the energy stored by plants that lived hundreds of millions of years ago.=]
Coal energy comes from the sun. The coal is fossilized vegetation that grew in the sunshine eons ago. The vegetation took up the solar energy using photosynthesis and chlorophyll to produce green matter
bugers and poop - whoever wrote this needs to grow up! Coal comes from factories and you can make coal from fossil fuels.
Coal is a fossil fuel formed in ecosystems where plant remains were preserved by water and mud from oxidization and biodegradation , and which its chemical and physical properties have been changed as a result of geological action over time, thus sequestering atmospheric carbon. Coal is …a readily combustible black or brownish-black rock. It is a sedimentary rock , but the harder forms, such as anthracite coal , can be regarded as metamorphic rock because of later exposure to elevated temperature and pressure. It is composed primarily of carbon and hydrogen along with small quantities of other elements, notably sulfur . Coal is extracted from the ground by coal mining , either underground mining or open pit mining ( surface mining ).. Coal is the largest source of fuel for the generation of electricity worldwide, as well as the largest worldwide source of carbon dioxide emissions. Carbon dioxide is a greenhouse gas and the major contributor to an increase in global average temperature and related climate changes.  Gross carbon dioxide emissions from coal usage is slightly more than that from petroleum and about double the amount from natural gas .  ( Full Answer )
One tradition you often hear of in the United States is "if you are not good, you will get coal in your stocking". Well, this actually stems from the tradition of La Befana. On the night that Jesus was born, the 2 Wise Men had stopped by her house to ask for directions, afterward they had asked her …to join them, but she refused. Later on, a shepherd stopped by to ask her for directions as well, and then also asked her to join him to come pay respects to the baby Jesus, but she refused again. Later that night, she saw a great bright star in the sky and then reconsidered going to look for the stable where Jesus was. She had collected some toys of her own child that had died, to give to the baby Jesus. But, she could not find . the stable. So to this day, she goes around looking for Jesus and leaves toys for the good children, and coal for the bad ones. Carbone Dolce is often used as the traditional joke in Italy, its rock candy that looks almost exactly like coal. ( Full Answer )
Carbon dioxide, oxides of sulphur, oxides of nitrogen, carbon monoxide, unburned hydrocarbons, and quite a few others.
Coal is an organic sedimentary rock because it is derived largely from the remains of plants.
From Webster's Dictionary: A black, or brownish black, solid, combustible substance, dug from beds or veins in the earth to be used for fuel, and consisting, like charcoal, mainly of carbon, but more compact, and often affording, when heated, a large amount of volatile matter.
coal is found underground - and is formed by buried forests and vegetable matter being compressed over millions of years
Most of the Carbon in both coals and oils come from Flora andFauna, i.e animals and plants. Over thousands of years the naturalcarbon from the lifeforms (usually from wet areas like swamps orshallow marine areas) are compressed, recieving a tonne ofpressure, until eventually becoming coal seams that… we see today.

We usually think out of 100 percent when we think percent, but out of 150 percent 32% comes from burning coal.
coal is fuel. it can be burned to make heat or energy. the energy is coal was once sunlight energy that plants used. Petroleum and natural gas are also fuels. most scientists think natural gas petroleum form in a way similar to coal. however, they did not begin as plants. they began as small sea org…anisms. so, crude oil and natural gas are called fossil fuels.

Coal mining is a dangerous job in the coal mines, as you see by the devastating explosion just recently. Coal also produces many harmful gases into our atmosphere, so renewable resources are safer for people, animals, the earth, and everything!
Coal is only as homogeneous as the original materials from which it is formed. Many soft coals (lignites) are formed by the burial and compression etc, of forest or shrubland. Thus the coal formed from this will never be homogeneous, and you may find fossilized branches in the material. Many 'b…rown coals' give off much gas (methane) and this is a hazard to mining. Other coals are formed from mossy bogs, which were in a depression, and which continued to sink, with the moss continuing to fill the hollow. Many of these coals, buried and subject to compression and heat, form coals that are much more homogeneous. These coals, if buried sufficiently, give off very little gas, and are much darker in colour. The lowest rank of coal would be peat, which is not changed much from the original plant material. Rank then passes through the lignites and other brown coals, then through the black shiny coals to Anthracite, the highest grade of coal. Graphite may be considered the highest grade of coal, but is not as useful a fuel as the others. ( Full Answer )
Yes. Coal has porosity, and according to the link, it can range from 0.1% to 10%. An important area of research is the study of the pore system of coal, which can be intersected by fissures. These fissures can help transport and produce coal bed methane (CBM). See related link.
Correct. Although they are based on the same element (carbon) they have vastly different structures and atomic arrangements, resulting in very different physical and chemical properties. Such forms are known chemically as allotropes .
It does not have coal on it but it used to thousands of years ago.
cause that's what It does, coal naturally burns in one fuel sourceso that's what makes it up to be burning in a coal stock, once thecoal is burned it creates heat energy which is naturally anonrenewable resource once it is actually burned.
It isn't - it is a mixture of compounds. There are 100s of chemical compounds that have been extracted from coal. It is a mixture of these
It can take anywhere between 15-20 secs but it may take up to 30 if their is alot of people on the server
No. Coal is dead matter, the outcome of long periods of high pressure and temperature following death and decay of living organisms (normally plant matter). The organisms had DNA when they were alive, but the molecules have long since decomposed and converted to other chemicals and structures.
Petrochemicals come from petroleum -Oil. However, some chemicals extracted from petroleum (petrochemicals) , may also be extracted form coal.
coal is created by the deposition and compaction of huge plant(organic) material deposited into a basin,with the increasing depth the high rank of coal is formed. The order is:- peat>lignite>bituminous>anthracite Peat is formed at shallow depth and on moving downward anthracite is formed at greater …depth. ( Full Answer )
I do nothing with coal. Others burn it to release the contained energy through the process of combustion. The result of combustion is heat. The heat is then most often used to create steam. The steam is then used to spin a turbine, which creates electricity. So, in a nut shell, coal is electricity. … Santa Klaus also uses lumps of coal to send a clear message to naughty children (or so rumor has it). ( Full Answer )
coal become coal because when animals get buried in swamps years ago and when it is dug up now it became coal that is correct p;ants a long time ago are coal
Fossil Fuels are used to provide to energy to perform work. Such as using coal to provide energy for a train to work.
Coal is a fossil fuel created from the compaction of the earth on fossil vegetation from millions of years ago. It's primary constituents are carbon, sulfur, hydrogen (partly as moisture), nitrogen, oxygen and ash. Carbon is the most prominent constituent.
it is an organic matter of plants which were decay and decompose after their termination
According to the US Institute for Energy Research, coal in 2005 was responsible for 26% of global energy production. This percentage is dropping each year as more countries and power plants move to oil and gas, the burning of which releases less harmful carbon dioxide emissions than coal. There is… movement too in the establishment of renewable energy power (solar, wind, water, hydro, tidal and wave, geothermal, ocean thermal, biomass and biofuel). ( Full Answer )
My nation is USA. Most of the coal comes from within the country. The US actually exports coal to other countries.
As of 2011, about 42 percent of electricity in the US was derived from coal. There is a push in the 21st century to use other methods of electricity since coal is harmful to the environment.
As of 2013, the amount of the US's electricity that comes from coal is approximately 42% This makes up the mass majority of electricity service in the country. Natural gas is the second most popular source.
How come world thermodynamicists fail to recognize that what makes coal combustion the energy of choice for electricity is the reversible piston turbine reversible process?
I am not sure what you mean. What process is that? Any combustible fuel will work, not just coal. You can read about the thermodynamics part by looking for a description of the "Carnot engine". The process is NOT reversible; although the Carnot engine is reversible in theory, there are always losses… in practice that make it irreversible; also, the fact of burning the coal is not reversible.
