Coal is abundant in the United States and other devel-oped and developing countries, such as Russia, China, and India. Coal is relatively inexpensive and an excellent source of energy and byproduct raw materials. Because of these factors, domestic coal is the primary source of fuel for electric power-
Soft coal is also known as brown coal or lignite. China produces more hard coal than any other country by a factor of about three. The whopping 3,162 million metric tons of hard coal produced by China dwarfs the output of the second and third-ranked producers—the U.S. at 932 million metric tons and India at 538 million metric tons.

Anthracite is the highest rank of coal. It is a harder, glossy black coal used primarily for residential and commercial space heating. Graphite is no longer coal. It is difficult to ignite and not commonly used as fuel; it is most used in pencils, or powdered for lubrication. Thermal v metallurgical coal: the most important coal classification.
The International Coal Classification of the Economic Commission for Europe (UN/ECE) recognises two broad categories of coal: hard coal – coal of gross calorific value (CV) of >5700 kcal/kg (23.9 GJ/t) on an ash-free but moist basis and with a mean random reflectance of vitrinite of at least 0.6. Hard coal is

coal classification, any of various ways in which coal is grouped. Most classifications are based on the results of chemical analyses and physical tests, but some are more empirical in nature. Coal classifications are important because they provide valuable information to commercial users (e.g., for power generation and coke manufacturing) and to researchers studying the origin of coal.
