• Coal is regarded as a non-renewable source obtained from fossil fuels which are black combustible substances.

• Coal is primarily used as a fuel for the generation of electric power. It can generate an abundant source of electricity worldwide.
• In heating-powered coal where 1 tonne of coal is used it yields 70% of a solid coke mass and 30% of coal tar and gas.
• Coke is produced by baking coal at high temperatures in the absence of oxygen in order to remove volatile hydrocarbons present in coal. It is also scientifically proven that coke produces double the heat content of the coal required.
• Coal tar is a black thick liquid produced by heating coal at high temperatures. Coal tar is used primarily for the production of refined chemicals and coal-tar products.
