Coal is the largest single source of electricity worldwide. It helps produce over 70% of the world's steel and is used in industrial processes like cement manufacturing. In the past it was used to power trains.
Coal can be processed many different ways to create a wide variety of products, from carbon filters to pharmaceuticals. It is used to produce fertilizer, paint and preservatives, plastics, computer chips and circuit boards, perfumes, explosives, insulation, roofing materials and sugar substitutes.
Gases, oil and tars extracted can be extracted from coal and used to manufacture products ranging from gasoline and perfumes to mothballs and baking powder.
Coal tar is used for paving roads and tarring roofs.
Coal gas in the 1940’s was used for residential lighting and cooking, but it was phased out because it was expensive. Today coal gasification processes are being developed to be more cost effective. Methanol is now being developed and used as a fuel for engines.
