Coal
Coal is a black or brownish-black sedimentary rock that can be burned for fuel and used to generate electricity.It is composed mostly of carbon and hydrocarbons, which contain energy that can be released through combustion (burning). Coal is the largest source of energy for generating electricity in the world, and the most abundant fossil fuel …

Cement
There are four stages in the manufacture of portland cement: (1) crushing and grinding the raw materials, (2) blending the materials in the correct proportions, (3) burning the prepared mix in a kiln, and (4) grinding the burned product, known as " clinker," together with some 5 percent of gypsum (to control the time of set of the cement). The three processes of …

Petcoke Fact Sheet
Since petcoke has a higher heat content than coal, less petcoke than coal is required to generate the heat necessary to maintain an industrial process. For example, a 500 MW electric generating unit (EGU) operating at full output will consume 211 ton/hour of Illinois Basin high sulfur coal, but requires only 166 ton/hour of petroleum coke.

Glossary
In combustion different fossil fuels release different amounts of carbon dioxide for the same level of energy use: oil releases about 50 percent more carbon dioxide than natural gas, and coal releases about twice as much. Cement manufacturing releases about half a metric ton of carbon dioxide for each metric ton of cement produced.
