Coal was important to the Industrial Revolution because it burned hotter than wood charcoal. The additional heat was needed in the boilers that ran the steam engines developed during the Industrial Revolution, according to the United States Department of Energy.
Coal is being used in power generation, the manufacturing of cement, iron and steel. Coking coal is used to produce coke, which in turn is used to produce pig iron. Coal used for energy generating is declining due to an increase in the use of natural gas and nuclear power. The overall coal production however is increasing, for other purposes.
