The poorest quality of coal is known as lignite, often referred to as brown coal. It has the lowest carbon content, typically around 25-35%, and contains high moisture levels, which results in lower energy content compared to higher-grade coals like bituminous or anthracite. Lignite is primarily used for electricity generation in power plants due to its relatively low energy efficiency and high emissions when burned.
