Coal is the most abundant form of solid fuel, being used in industry and in the manufacture of coke, tar, hydrocarbons, and (formerly) gas. It is formed from the remains of trees and other plant material, mostly during the Carboniferous period. Types of coal include anthracite, bituminous coal, and brown coal, and it is obtained by deep or opencast mining. The pre-eminent fuel of the Industrial Revolution, coal has lost much of its importance to oil and natural gas
