Some disadvantages of clean coal is that it pollutes the air.
No coal is not really environmentally friendly . There are a lot more disadvantages than advantages when it comes to coal.
advantages- its clean. disadvantages- its not as vierment friendly as solar power.
because the coal helps the person to cook if he or she does not have a stove or any cooking materials
Some disadvantages of coal powered plants are; 1. a coal powerplant produces 3700000 tons of CArbon dixode in a year. this is also one of the main causes of global warming. 2. all the mercury taken from the coal has to be disposed, and usually it is disposed in a lake.
its bad for the environment,and being a solid,its dirty
Harms the ozone layer And coal may soon run out
coal is a nonrenewable resource, so once we use it all we will never have it again. also people get killed in coal mines because they can collapse after a point of time.
1- it pollutes the air2- it may run out soon (coal.)
Many bad BAD things.. Did I help you..? No okay! :)
Advantages of coal: Coal burns warm and for a long time. Coal produces energy, Coal is easy ti mine. Disadvantages: Coal can spontaneously combust if it is not strategically piled and stacked and separated, also must be rotated throughout its pile. Pollution is another disadvantage of coal. It is also expensive to move around from one coal yard to another.
just somedisadvantagesof coal power .It takes YEARS for debrie to form into coal (debrie=grass dead animals etc.) .It is NON renewable .It is NOT an eco friendly energy source
Burning coal for elstricity has no advandages, it only causes disadvantages like making the air polluted and bad for the workers health.
Advantages... 1. Coal is one of the most abundant sources of energy for mankind. 2. Its good for fire too. Disadvantages... 1. Burning coal is harmful waste such as carbon dioxide, sulfur dioxide, nitrogen oxides, sulfuric acids, arsenic and ash. 2. Leads to acid rain
There are several disadvantages to burning coal.Even before it is burned, coal mining is a dangerous and difficult job in which people are killed every year, and which often results in black lung disease even for those coal miners who do not die in mining accidents.Burning coal releases several forms of air pollution.It always releases large amounts of carbon dioxide, which is a greenhouse gas that is the major cause of global warming.Some varieties of coal also release significant quantities of sulphur dioxide, which leads to acid rain.Various other impurities in coal, such as mercury, also are released into the air.
You can't overcome them! The main disadvantage of coal is that it is a non-renewable fossil fuel. Therefore it will run out in the future. We need to find viable alternative energy sources.
it hurts the environment by realising carbon dioxide, sulphur dioxide, ash etc.

Coal has only one advantage relative to oil, which is that it is abundant and relatively inexpensive. Disadvantages include, it is more polluting (due to impurities in the coal) and it is harder to handle; oil can be pumped, whereas coal has to be shoveled. Coal mining is often more difficult and dangerous than pumping oil out of the ground. Coal dust creates the dangers of explosion, and black lung disease.
Using coal to generate electricity releases many pollutants into the atmosphere. Some contribute to acid rain. Others, like carbon dioxide, contribute to global warming.
As it is one of the natutal resources (Coal, Oil, Natural Gas) one the supply is gone it cannot be replaced.
The disadvantages of coal power are;1. It is non-renewable and it is causing global warming.2. Although it is now cheap, if the coal continues to be used in such a way, it will soon be very expensive.3. Burning a fossil fuel produces carbon dioxide, which contributes to the greenhouse effect, warming the Earth.4. Burning coal produces more carbon dioxide than burning oil or gas.5. Mining coal can be difficult and dangerous. Strip mining destroys large areas of the landscape.6. Coal-fired power stations need huge amounts of fuel, which means train-loads of coal almost constantly. In order to cope with changing demands for power, the station needs reserves. This means covering a large area of countryside next to the power station with piles of coal, which destroys plants and ruins landscapes.
There are several disadvantages to using coal to generate electricity. When coal is burned, it releases lots of carbon dioxide, which is a problem because the atmosphere already has too much carbon dioxide and it is causing global warming. In addition, there are impurities in coal which result in other forms of air pollution, particularly sulfur dioxide which results in acid rain. Coal mining is also a dangerous activity that results in many deaths. And although there is a lot of coal, it is still not a renewable resource, and it will eventually run out, if we continue to burn it.
Some disadvantages:- Uranium is a toxic and radioactive elementSome advantages:- Uranium is a very important source of energy without any greenhouseeffect; also some countries don't have coal, oil or methane but haveuranium.
The disadvantages of inventions in the Industrial revolutions were that both animal and human 'energy' power was replaced by 'coal & steam' power.The quality of work deteriorated with the introduction of mass production. Patronage to craftsmen by the 'feudal lords' was lost.
