Coal is an organically derived material. It is formed from the remains of decayed plant material compacted into a solid through millions of years of chemical changes under pressure and heat. Its rich carbon content gives coal most of its energy content. When coal is burned in the presence of air or oxygen, heat energy is released. This energy can then be converted to other forms of useful energy. Primary applications for coal are thermal (e.g., electricity generation) and metallurgical (e.g., coking or steelmaking coal). Key facts
Learn more about coalCoal industryIn 2017, coal made up 27% of the world's energy supply. In Canada, many parts of the nation have abundant low-cost, domestic coal, while other regions have easy access to an international supply. The Canadian coal industry produces coal for use in metallurgical applications (e.g., coking or steelmaking) and thermal applications (e.g., electricity generation). Nearly half of the coal produced in Canada is thermal and half is metallurgical. Some power-generating companies not only use coal for electricity generation but also own coal mines or are involved in coal production themselves. Other companies generate electricity from purchased coal. International contextGlobal coal production in 2019 is estimated at 7.9 billion tonnes, increasing by 116 million tonnes from 2018. The top 5 producing countries accounted for 79% of the world's coal production.
