Linyit, also known as lignite, is a type of coal that is considered the lowest rank of coal due to its relatively low carbon content. It is brownish-black in color and has a high moisture content, making it less efficient as a fuel source compared to higher-grade coals. Linyit is primarily used for electricity generation in power plants and is often found in large deposits near the surface, making it easier to mine. The formation of linyit occurs from the remains of ancient plants that have undergone a process of decomposition and compaction over millions of years. It is commonly found in regions such as Germany, Turkey, and the United States, where large reserves are mined. While linyit is a significant energy source, its combustion releases more carbon dioxide and pollutants compared to higher-grade coals, raising environmental concerns.
