What are the effects of coal industry?
Several principal emissions result from coal combustion: Sulfur dioxide (SO2), which contributes to acid rain and respiratory illnesses. Nitrogen oxides (NOx), which contribute to smog and respiratory illnesses. Particulates, which contribute to smog, haze, and respiratory illnesses and lung disease.
What is the development of coal?
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.
Is coal still being formed?
Coal is very old. The formation of coal spans the geologic ages and is still being formed today, just very slowly. Below, a coal slab shows the footprints of a dinosaur (the footprints where made during the peat stage but were preserved during the coalification process).
How important is coal in our everyday lives?
Uses of coal Power generation is the primary use for coal worldwide. Thermal coal is burnt to create steam that drives turbines and generators for the production of electricity. Metallurgical (coking) coal is a key ingredient in steelmaking. Coal is used as a key energy source in cement production.
