Coal - Wikipedia

Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

Life Cycle Assessment of Coal-fired Power Production

Coal has the largest share of utility power generation in the United States, accounting for approximately 56% of all utility-produced electricity (U.S. DOE, 1998). Therefore, understanding the environmental implications of producing electricity from coal is an important component of any plan to reduce total emissions and resource consumption.

How (and Why) to Value a Coal Mine FTI Journal

Thermal coal prices depend on the calorific value of the coal, as well as the level of impurities present. Everything being equal, the higher the CV and the lower the impurities, the higher the expected price per ton. A key characteristic of commodity companies is their dependence on the price of the commodity for their cash flow and value.

Energy Resources: Fossil Fuels - Claranet COM

Crude oil (called "petroleum") is easier to get out of the ground than coal, as it can flow along pipes. This also makes it cheaper to transport. I ought to point out that some scientists are claiming that oil is not a 'fossil' fuel - that it is not the remains of prehistoric organisms after all. They claim it was made by some other, non-biological pr
