A black or brownish-black solid, combustible substance formed by the partial decomposition of vegetable matter without access to air. The rank of coal, which includes anthracite, bituminous coal, subbituminous coal, and lignite, is based on fixed carbon, volatile matter, and heating value. Coal rank indicates the progr [..]

compressed plant remains—peat, lignite, subbituminous, bituminous and anthracite (in order of increasing carbon, and decreasing water, contents)

A natural material formed from fossilized plants; made up of carbon with various organic and some inorganic compounds. Used as fuel.

Coal is a burnable carbonaceous rock that contains large amounts of carbon. Coal is also a fossil fuel—a substance that contains the remains of plants and animals and that can be burned to release energy. Coal contains other elements such as hydrogen, oxygen, and nitrogen; has various amounts of minerals; and is itself considered to be a mineral of [..]

The metamorphic product of stratified plant remains. It contains more than 50 percent carbon compounds and burns readily.

Hot as a coal. The expression has an obvious allusion.

A fossil fuel mostly made up of carbon that is a sedimentary rock. It has been underground for millions of years and is usually extracted through mining.

A solid fossil fuel found in the earth. Coal is burned to make electricity in other countries.

large base load generators. Nova Scotia has several large coal units located in Cape Breton. These typically run at full output, and running at less than maximum output causes reduced efficiency. As these plants burn a fossil fuel, they have carbon and other atmospheric emissions.

Coal is ranked by its degree of transformation or maturity, increasing in carbon content from lignite to sub-bituminous to bituminous to anthracite.

A black or brownish-black solid combustible substance formed by the partial decomposition of vegetable matter without access to air.

A readily combustible black or brownish-black rock formed in ecosystems where plant remains were preserved and fossilized by water and mud. It’s composed primarily of carbon and hydrogen along with small quantities of other elements, notably sulfur. Coal remains the most commonly used fuel for generating electricity in the nation and around the wor [..]

Manufactured gas made by distillation or carbonization of coal in a closed coal gas retort, coke oven or other vessel. 

A readily combustible black or brownish-black rock whose composition, including inherent moisture, consists of more than 50 percent by weight and more than 70 percent by volume of carbonaceous material. It is formed from plant remains that have been compacted, hardened, chemically altered, and metamorphosed by heat and pressure over geologic time.

kohl During Carboniferous period much of world was covered with vegetation growing in swamps. This vegetation died and became submerged under water. As decomposition took place, vegetable matter lost oxygen and hydrogen atoms, leaving a peat deposit with a high percentage of carbon. As time passed, layers of sand and mud settled from water over som [..]

A fuel consisting of black or brown rock that is taken out of the ground at large mines.

As defined by Morningstar’s Global Equity Classification Structure, companies in the coal extraction industry. Coal

A black or brownish black solid, combustible carbon-rich substance formed by the partial decomposition of vegetable matter without access to air. Coal is one of the most important of the primary fossil fuels. It is indispensable to life and constitutes humankind's main source of energy.

a material for drawing made by carbonization of deciduous sprigs. E.g. beech.

A solid, brittle rock, formed by partial to complete decomposition of vegetation. It is the primary fuel used by iron and steel producers. Western coal has been widely used since the mid-1970s due to its lower sulfur content.  A 1,000-foot laker can carry enough coal to produce the electricity needed to power a metropolitan area the size of Greater [..]
