So the cost of coal per unit of electricity is (3497/100,000) 3.5 cents per unit.
Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.
Coking coal (or metallurgical coal) is used for the production of coke, which is an important fuel in the blast furnace used for the production of steel. Steam coal (or thermal coal) is used in generating power and central heating. Australia, Indonesia, Russia, US and South Africa are some of the major countries exporting coal.
