Coal – Types, Uses and Formation

There are four types of coal - peat, lignite, bituminous and anthracite. Each type has different proportions of carbon and thus, have different uses. Peat - This type of coal has less than 40% to 50% of carbon, while the remaining is moisture. This makes it difficult for us to ignite and cannot be easily used.
