It is easily found and extracted, it burns easily and gives a good thermal energy output, better than wood for example.
Coal is a fossil fuel. It stores energy derived from sunlight byorganisms that later died, were buried and later on became thisfuel.
Coal energy is energy derived from the burning of coal. Coal is essentially fossilized carbon.
1. "A dark-brown to black solid substance formed from the compaction and hardening of fossilized plant parts in the presence of water and in the absence of air. Carbonaceous material accounts for more than 50 percent of coal's weight and more than 70 percent of its volume. Coal is widely used as a f…uel, and its combustion products are used as raw material for a variety of products including cement, asphalt, wallboard and plastics" 2. A natural dark brown to black graphitelike material used as a fuel, formed from fossilized plants and consisting of amorphous carbon with various organic and some inorganic compounds 3. A piece of glowing, charred, or burned wood or other combustible substance. (charcoal) ( Full Answer )
do you mean "If coal were inexhaustible how is it harnessed forenergy?" First, it is not inexhaustible; every bit of coal that isburned adds to the pollution burden of the atmosphere. Second,coal, whether inexhaustible or not, is harnesses for energy the wayit always has been. It is burned to boil w…ater to make steam. Thesteam drives a turbine, which turns a generator which produceselectricity. . +++ . I'm afraid the second sentence introduces a non-sequiteur. Coalcan be burnt cleanly but its combustion products still includecarbon-dioxide. However any polluting effect has nothing to do withbeing inexhaustible or not. SO to answer the question ,coal could not be inexhaustible - it is a finite resource - and itcan be harnessed only by burning it to release its potential heatenergy as the last sentence details. Coal can also be distilled togive coke, gas and various chemical products. ( Full Answer )
it is formed by being burned which causes heat, which can also be converted into motion energy.
the coal is designed to absorb heat at when heat hits it itstores that heat . ++++ . No. The energy is stored by coal simply being a combustiblematerial, so it contains potential chemical energy.
No, coal took many millions of years to form, which makes itdefinitely non-renewable. That's because when it's all used up,there would be a long wait for more coal to form.
Coal energy is present in coal. There are two types of coal: bituminous, or 'soft' coal, and anthracite coal, or hard coal.Coal is a hard rocky substance that is the left-over carbon from huge amounts of plants from ages past which died, and have been covered over by sometimes thousands of feet of r…ock and dirt.

Energy cannot be 'made' or 'destroyed'. It can simply be transformed to a different type of energy. Coal contains chemical energy, which will for example, be converted to heat energy in say a coal fired industrial boiler.
well first of all it pollutes. also coal is nonrenewable so we would run out anyway. it would not be reliable. wind, solar, or hydroelectric energy are more reliable becuase they are renewable and do not pollute.. coal is also mined which is bad for the environment. some people dont do reclamation s…o its bad ( Full Answer )
Coal is from decayed plants buried hundreds of millions of years ago. Plants need sunlight to grow. ------- Plants using photosynthesis, convert sunlight, water and carbon dioxide to form simple sugars. Coal is the altered remains of prehistoric vegetation that originally accumulated in swamp…s and peat bogs. The build-up of silt and other sediments, together with movements in the earth's crust (known as tectonic movements) buried these swamps and peat bogs, often to great depths. With burial, the plant material was subjected to high temperatures and pressures. This caused physical and chemical changes in the vegetation, transforming it into peat and then into coal. Coal formation began during the Carboniferous Period - known as the first coal age - which spanned 360 million to 290 million years ago. ( Full Answer )
Coal is a NON-renewable energy as when burnt, the Coal combusts, emitting carbon dioxide, among other harmful products. A renewable energy would be wind or tidal or solar energy for example.
Coal is burned and the energy is created from the heat of the coal burning and is collected and used and it gives off more energy than other things like peanuts for example. And coal is used for electricity and also heating homes in some places.
\nwe get energy out of coal by chemical methods may be by combustion or by any other means but not physically by direct means .( however we can convert any form of energy into any other form.)
Here are seven cons for coal energy. The first is Greenhouse Gas Emissions. One of the biggest cons of Coal Energy is that it releases Carbon Dioxide which has been sequestered for millions of years in the dead bodies of plant and animals. The next is Coal Mining Deaths. Coal Mining has resulted in …thousands of deaths each year ever since man discovered coal. A third is Devastation of Earth and Scenery near Coal Mines. Open Cast Mining of Coal has resulted in destruction of the habitat and destruction of the scenery. A forth is Displacement of Humans due to Mining Destruction. In West Bengal, India people are being displaced in huge numbers as the hollowing of the earth due to underground coal mining has made those places unsafe as the Land Caves in without warning. A fifth is Emission of Harmful Substances like Sulfur Dioxide, Carbon Monoxide, Mercury, Selenium, Arsenic, and Acid Rain. Thermal Plants emit harmful substances such as Mercury and Sulfur Dioxide which cause health hazards among the surrounding population and Acid Rain. A sixth is Global Warming. Coal is the Biggest Contributor to Global Warming generating billions of tons of carbon dioxide during. The last is price. Prices for all fossil fuels are rising, especially if the real cost of their carbon is included. ( Full Answer )
Not really.. Energy is released when coal is burned. It is not coal itself, but the reaction of oxygen and coal once ignited that results in energy.
When it is burned in air (this is a chemical reaction with oxygen) energy is released as heat.
The energy in coal is chemical energy. The usual way to extract itis to burn the coal converting it to heat energy. This can then beturned into electrical energy Fuels like gasoline and coal are sources of energy which means theystore energy
In simple terms: coal is used to heat boilers that transfers water into steam (heat Energy). The steam (the heat energy) is passed upon turbines and moving them (producing mechanical energy) which in turn moves the generators to produce electricity.. The answer above is to get electricity as the do…mestic energy. . Another alternative of course is to use coal directly (or after gasification) to use it for domestic heat energy purposes (eg, cooking ). . ( Full Answer )
The coal is set fire to so it heats water which evaporates. This makes a magnetic spin between two coils of wire which generates electricity. :)
Because it is the main provider of all our energy, more than hydro, nuclear, gas and oil combined!
Of course. When you use it, you can't make more of it, you have to dig it up. And once you dig some up, you can't get any more of it out of the same place, you have to dig in a different place.
You could argue that the sun has provided all the energy for theorganic materials that coal consists of. Or even the compressionand heat that coal suffered from during its formation ( As a springthat becomes compressed gaining potential energy )
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 does not produce energy. Think of coal (or any current fuel source) as a storage medium similar to a battery, or even a mass at a height. The potential energy that can be released is finite, but available for use. All that is required are the proper conditions to do so. These conditions are: S…ufficient Heat to provide the energy needed to break enough of the carbon and hydrogen bonds so that the process becomes self sustaining. Sufficent Oxygen so that the carbon and hydrogen bonds and creates molecules at alower energy level. So Where did the energy come from that is stored in the coal. Eventually it can be traced back to sunlight that was absorbed by plants and used to create carbon hydrogen molecules. ( Full Answer )
Around 770007766 Kilajoules is produced from coal even though it is anonymous because it is not 100% efficient even though it's not as reliable.
Coal is abundant and easy to harvest from the earth to produceelectricity relative to nuclear energy. Solar energy is abundantbut difficult to harvest compared to coal.
Yes, the energy stored in coal came from the sun. Plants using an ingenious process called photosynthesis, use energy from the sun, to take carbon-dioxide from the air, use the carbon and release the oxygen back to the air. After the plant is eaten or dies and is decomposed or burned (the net ef…fect is the same) the oxygen again breaks the chemical bonds, releasing the energy from the sun and liberating the carbon-dioxide back to the air to become the next generation of plants. Coal is carbon from the air and energy from the sun. ( Full Answer )
By burning it - usually (but not always) in order to turn water into steam, and using the steam to turn turbines.
How is Coal Converted to Electricity? Steam coal, also known as thermal coal, is used in power stations to generate electricity. Coal is first milled to a fine powder, which increases the surface area and allows it to burn more quickly. In these pulverised coal combustion (PCC) systems, the powder…ed coal is blown into the combustion chamber of a boiler where it is burnt at high temperature (see diagram below). The hot gases and heat energy produced converts water - in tubes lining the boiler - into steam.. The high pressure steam is passed into a turbine containing thousands of propeller-like blades. The steam pushes these blades causing the turbine shaft to rotate at high speed. A generator is mounted at one end of the turbine shaft and consists of carefully wound wire coils. Electricity is generated when these are rapidly rotated in a strong magnetic field. After passing through the turbine, the steam is condensed and returned to the boiler to be heated once again. The electricity generated is transformed into the higher voltages (up to 400,000 volts) used for economic, efficient transmission via power line grids. When it nears the point of consumption, such as our homes, the electricity is transformed down to the safer 100-250 voltage systems used in the domestic market. Efficiency Improvements Improvements continue to be made in conventional PCC power station design and new combustion technologies are being developed. These allow more electricity to be produced from less coal - known as improving the thermal efficiency of the power station. Efficiency gains in electricity generation from coal-fired power stations will play a crucial part in reducing CO 2 emissions at a global level. Efficiency improvements include the most cost-effective and shortest lead time actions for reducing emissions from coal-fired power generation. This is particularly the case in developing countries where existing power plant efficiencies are generally lower and coal use in electricity generation is increasing. Not only do higher efficiency coal-fired power plants emit less carbon dioxide per megawatt (MW), they are also more suited to retrofitting with CO 2 capture systems. Improving the efficiency of pulverised coal-fired power plants has been the focus of considerable efforts by the coal industry. There is huge scope for achieving significant efficiency improvements as the existing fleet of power plants are replaced over the next 10-20 years with new, higher efficiency supercritical and ultra-supercritical plants and through the wider use of Integrated Gasification Combined Cycle (IGCC) systems for power generation. A one percentage point improvement in the efficiency of a conventional pulverised coal combustion plant results in a 2-3% reduction in CO 2 emissions.. ( Full Answer )
Coal has several disadvantages as an energy source. 1. Burning coal releases large amounts of carbon dioxide, contributing to global warming. 2. Burning coal also releases various other pollutants which lead to acid rain and other forms of environmental harm. 3. Coal mining has always been a very da…ngerous business with many fatalities, which we have recently seen in China and in West Virginia. Because coal contains carbon it releases carbon dioxide when it is burnt. Carbon dioxide is the pollution that is causing global warming. The only real problems are that it pollutes the atmosphere and its not infinite. However, while known oil reserves are projected to only last another 50 years at our current rate of use, our coal mines have barely been touched and should continue to be a source of fuel for a long time.I guess I should also mention that it can be very dangerous to mine it. Then again that is why coal miners make the amount of money that they do. ti make people ill ( Full Answer )
Yes coal was formed by the bio materials of forests and swamps and the energy as now came from the sun.
Communities all come together when a coal mine disaster occurs. Some coal barons donate magnanimously to their favorite charities, especially to congressmen unimpressed by the science of anthropogenic global climate change.
They burn it...for example like a huge Ameren Power Plant, you will see the trains pull in and out during the deep cold winters, and in return large bellows of smoke come out of the huge stacks.
The energy stored in coal that is converted to heat is chemical energy. Of course coal, like any other matter, also has stored nuclear energy.
Think of coal like wood. In a wood stove or furnace, wood is burned to produce heat. Coal contains more energy and is cheaper that wood, however wood is renewable. The large coal power plants that run use coal to produce heat by burning it, heating water. When water heats up to steam, it has more pr…essure. This pressure is used to turn generators. The electricity produced will be direct current. The power plant will have a converter to change the DC into AC, Alternating Current. ( Full Answer )
You burn it for heat, which is then used to drive some type of heat engine to do work.
Coal and solar energy are alike because they both are having to do with energy and they are both formed ny the sun or have sun in them. Although, solar energy is renewable and coal is non-renewable they both have some similarities.
When coal makes energy, it creates a wasted gas, called Carbon Dioxide (CO2). Carbon dioxide contributes to the greenhouse effect, which keeps our earth warm. Liberal idiots claim that the use of oil and natural gasses is going to end the world in multiple ways. There is no other energy in the world… that we can contain and is as powerful as gasoline and oil. ( Full Answer )
petroleum and coal are both non renewable resources. this means that they can not be replaced in a reasonable amount of time. petroleum and coal also belong to a family of resources called fossil fuels. these are resources that are made from dead plant and animal matter. other forms of fossil fuels …are gasoline, and natural gas. ( Full Answer )
No, coal is not an alternative energy source. "Alternative" energysources means energy sources other than fossil fuels(coal, oil, and natural gas).
The coal is burnt to heat water into steam. the steam jet in turn is used to push a turbine the spinning turbine is connected onto a generator that generates electricity. The energy from a nuclear materials is utilized in the same way.
coal is found from charcoal..........a special kind of rock found about 4 feet below earths surface
From a practical standpoint, there is no cheaper source of dependable energy then coal. This ignores environmental impacts and mining accidents though. Wind and solar have very high up front costs and require other sources of energy to maintain the steady stream supply, thus they are still not pr…actical for more then small portion of power. Many of these systems never return the initial investment of the generators. Nuclear energy is actually very cheap, from a operating standpoint, but ecological and waste storage costs increase the overall costs. Adding the cost of creating massive waste lands is hard to quantify, but is certainly expensive/ Oil is also a possible energy source, but major deposits in the United States have no been exploited as of yet and political stability in other regions raise transporting costs and creates wars.

Not sure if this will answer your question, but I'll give it a shot. It's less about the fact that is is coal and more about the fact that coal gives off heat. When coal was first being used as a heat source, it was cheaper than wood and there was a lot of it. So really the origin of the energy is i…n the heat that the coal generates when on fire and less about the coal itself. ( Full Answer )
the reason morocco uses coal energy is because it has so many benefits and they borrow coal from countries.
No, as it is considered a non-renewable and emits a lot of CO 2 along with other substituents upon burning
Coal is the remains of ancient plant matter compressed by millions of tons of stone and dirt layers. So coal has energy that it got from those original plants. The plants got their energy from the Sun, mostly. So, it is acceptable to say that coal obtains its energy from the Sun.
The chemical energy stored in the coal is converted into heatenergy for space heating or to drive an engine. Coal contains carbon that mostly came from the atmosphere via theprocess of photosynthesis by vegetation using the Sun's energy tobreak down carbon dioxide in the air into carbon and oxygen.… Whenthose chemical bonds are reformed in the burning process, thatsolar energy is released and carbon dioxide is re-formed.
