Coal is a non-renewable fossil fuel used to generate electricity. It is a brownish-black sedimentary rock, composed of carbon and hydrocarbons. It is burned for fuel and this combustion produces energy. The conditions required for coal production were seen during the Carboniferous period, some 300 million years ago. Fossil fuels are formed from the remains of living things that existed millions of years ago. The production of coal takes millions of years, thus it is considered a nonrenewable resource. It is the largest source of energy and is found in huge quantities in the United States.
Uses of Coal
- It is solid dark-colored fuel found in deposits of sedimentary rock. burned to produce energy and is used to manufacture steel.
- It is also an important source of chemicals used to make pharmaceuticals, fertilizers, pesticides, synthetic dyes, and oils.
- Some historians believe it was first used commercially in China in 1000 B.C. In the early 18th century, the demand escalated when England iron founders John Wilkinson and Abraham Darby used coal, in the form of coke, to manufacture iron.
- The invention of the coal-burning steam engine by Scottish mechanical engineer James Watt in 1769 boosted the demand. During the 20th century uses of petroleum and natural gas reduce the demand. The black gold backbone of the industrial revolution, experienced a renaissance in the 1970’s after 30 years of neglect.
- At present, it is the second largest source of energy and it fulfills 24% energy demand of the world. World, 39% of electricity is produced by burning coal.
- It is used to make other metals such as aluminum and copper.
- It is used in the production of cement.
- Coal is heated with steam and then it is pressurized to produce ‘’town gas’’ that is used for lighting, cooking, and heating.
- Coal is easier to transport than other fossil fuels.
- It is considered to be an affordable source of energy.
- Coal just needs to be mined before use, whereas other fossil fuels need to be refined before their use.
- Coal is also used in other industries such as paper, glass, and textile industries.
Types of Coal
Coal is classified into four types which are lignite, sub-bituminous, bituminous, and Anthracite based on the carbon content and the amount of energy they can produce. These categories are explained below in detail:
Anthracite Coal – The best type of Coal
This is the highest-ranked, hardest, oldest, and least common type of coal. It possesses a high energy content, a high percentage of carbon more than 90%, and relatively little moisture or volatiles. It is low in volatile matter (oxygen and hydrogen). Anthracite burns with almost no smoke. Anthracite deposits account for only 5% of global output. Only China and U.S.A. have large deposits of anthracite.
Bituminous Coal
This is the second rank of coal, softer and younger than anthracite, and containing a lower percentage of carbon between 60% to 80% carbon content. Bituminous coal is the most mined and most widely available. It is suitable for heavy industry and is also used for cooking. It is mostly used in the steel industry. Bituminous shares nearly four-fifth of the global output of coal.
Subbituminous Coal
This type of coal is used for electricity generation. It is black and is rather dull. It is a lower grade of coal with only 35-45% carbon. Subbituminous type of coal possesses properties that are similar to Bituminous and Lignite.
Lignite Coal
This is the softest, youngest, and wettest rank of coal. Lignite is popularly known as “brown coal”. It has carbon content from 45% to 65% and highest the moisture. Lignite coal is used for generating thermal electricity and is being used for the chemical industry. Germany, Hungary, Russian Federation, Australia, and the Czech Republic possess large reserves of lignite coal.

Peat Coal
Apart from these 4 major types of coal, peat is the precursor of coal. Peat is the most inferior grade of coal that has been formed only through a very limited degree of decomposition. It contains only 30% of carbon and a much higher proportion of moisture and other volatile matters. Thus, peat generates very little heat and plenty of smoke.
Type of Coal | Average Energy Content (Btu per lb.) | Carbon Content (%) | Sulfur Content (%) | Percentage of Known US Reserves (%) |
Anthracite | 12,500 | 86-98 | 0.4-1.9 | 1.5 |
Bituminous | 12,000 | 50-86 | 0.8-5.0 | 51.0 |
Subbituminous | 9,000 | 30-40 | 0.6-1.8 | 38.0 |
Lignite | 7,000 | 40-60 | 1.6 | 9.5 |

Coal Reserves and Production Distribution by Country in the World
Coal is widely distributed over the earth and more than 70 countries possess large deposits. The major deposits lie in the Northern Hemisphere, mostly between 30°N to 50°N latitude. There is very little coal in the Tropics but a considerable amount in polar lands. The Russians, Norwegians, and Greenlanders all mine coal north of the Arctic Circle, and there are known deposits in Antarctica.
World coal reserves are about 1,139,471,430,000 tons (short ton, st), while coal consumption is about 8,561,852,178 (short ton, st). It means that coal will last for another 133 years. Although reserves are widely distributed in the world:

Conclusion
Coal is the most abundant yet cheapest source of non-renewable energy. It is obtained from fossil fuels and is developed in almost 1 million years. They are used for a variety of purposes but their major use is to generate electricity. It is a major source of energy in most countries in the world. Many of these countries produce coal b themselves. The top 10 countries producing coal include China, the USA, India, Russia, Indonesia, Kazakhstan, Poland, Germany, South Africa, and Russia. All these countries actively import and export their coal. With the increasing demand for this powerful resource, the world will soon run out of all its coal.
