The growth in coal demand was the second consecutive year of increases, following three years of falling consumption. As a result, the peak in global coal consumption which many had thought had occurred in 2013 now looks less certain. OECD demand fell to its lowest level since 1975.
Bituminous Coal: Great pressure results in the creation of bituminous, or "soft" coal. This is the type most commonly used for electric power generation in the U.S. It has a higher heating value than either lignite or subbituminous, but less than that of anthracite. Bituminous coal is mined chiefly in the Midwest & Appalachia
Nov 26, 2012 · The demand for metallurgical coke for blast furnaces is forcing the cokemaking industry to look for new sources of coking coals. Noncoking coals are attractive for use in the cokemaking coal blends, because they are cheaper and more available. In this study, a Chinese subbituminous coal with noncaking property was hydrothermally treated in order to modify its caking and coking properties

Anthracite and bituminous coal are two types of coal that are critical to the economy of the United States. Anthracite coal is used in a variety of manufacturing processes, but its primary use is in the formation of steel. Bituminous coal, on the other hand, is the type of coal most commonly used in America to produce electricity.
In order to meet this demand, an integrated set of solution will be needed : Expanding all economic energy sources : particularly oil, natural gas and coal, including others like renewable fuels and also perhaps nuclear.
