The four types of coal are anthracite, bituminous, sub-bituminous, and lignite. Anthracite is the highest grade, characterized by its hard, glossy appearance and high carbon content, making it an efficient fuel. Bituminous coal is the most commonly used type, primarily for electricity generation and steel production. Sub-bituminous coal has lower carbon content and energy output, while lignite, or brown coal, is the lowest grade, with high moisture content and limited energy capacity.
