Cogeneration An energy technology that involves recycling waste heat so that two useful forms of energy are produced from the same fuel.
Acid Deposition A type of air pollution that includes acid that falls from the atmosphere as precipitation or as dry acidic particles.
Strategic Petroleum Reserve An emergency supply of up to one billion barrels of oil that is stored in underground salt caverns along the coas
Fluidized Bed Combustion A clean-coal technology in which crushed coal is mixed with particles of limestone in a strong air current during combustion.
Structural Traps An underground geological structure that tends to trap oil or natural gas if it is present.
Salt Domes Structural dome formed when minerals evaporate and it vertically comes out of the earth.
Synfuel A liquid or gaseous fuel synthesized from coal or other naturally occurring sources and used in places of oil or natural gas. Also called Synthetic Fuel.
Coal Gasfication The technique of producing a synthetic gaseous fuel from solid coal.

Scrubbers Desulfurization systems that are used in smokestacks to decrease the amount of sulfur released in the air by 90% or more.
Resource Recovery The process of removing any material-sulfur or metals
Lignite A grade of coal that is brown or brown-black and has a soft woody texture.
Bituminous Coal The most common form of coal; is produced highly in amounts of heat and is used extensively by electric power plants.
Anthracite The highest grade of coal; has the highest heat content and burns the cleanest of any grade of coal.
