Since the beginning of industrialization in the 19th century, coal has had a significant impact on the world’s energy supply. To this day, coal remains one of the leading energy sources among all non-renewable resources worldwide. The use of hard coal, the most important type of coal, has even increased somewhat in recent years. Coal also has by far the largest reserves of all non-renewable energy resources.
