$\huge{\fbox{\fbox{\bigstar{\mathfrak{\red{Answer}}}}}}$

✨Lignite is the youngest type of coal. It is soft and ranges in color from black to shades of brown. As a result, it’s sometimes called brown coal. Lignite is mainly used for electricity generation and accounts for 17 percent of the world’s coal reserves.♥️

✨Sub-bituminous coal is the result of millions of years of continued pressure and high temperatures on lignite. It burns cleaner than other types of coal, producing less greenhouse gas emissions due to its low sulfur content. Sub-bituminous coal is used in electricity generation and also in industrial processes. This coal type makes up 30 percent of the world’s coal reserves.♥️

✨Bituminous coal is harder and blacker than lignite and sub-bituminous coal, and can be divided into two types: thermal and metallurgical. Together, they make up 52 percent of the world’s coal reserves and make up a majority of the coal industry. Thermal coal, as the name implies, is used in energy generation for heating, but it is also used for cement manufacturing and other industrial purposes. Metallurgical coal is used primarily mixed with iron ore to produce iron and steel.♥️

✨Anthracite is the most mature coal and thus has the highest carbon content of any type of coal. Nicknamed hard coal by the locomotive engineers that used it to provide energy to power trains, coal mines that produce anthracite or hard coal account for roughly 1 percent of the world’s total coal reserves, which represents a very small portion of the overall coal industry. Anthracite is also used in some older homes’ heating stove systems, and can be used as a smokeless fuel in hand fired furnaces.♥️

Answer 2

Answer:

The four types of coal are peat, lignite,bituminous, and anthracite. Peat is often not listed as a type of coal since the use of it as an energy source is limited today. However, it's still a type of coal and can be used as an energy source. Peat is the first step in coal formation.
