Energy
the ability to do work
First Law of Thermodynamics
energy is neither created nor destroyed but changed from one form to another
Surface Mining Control and Reclamation Act (1977)
law sets forth minimum uniform requirements for all coal surface mining on Federal and State lands, including exploration activities and the surface effects of underground mining. Mine operators are required to minimize disturbances and adverse impact on fish, wildlife and related environmental values and achieve enhancement of such resources where practicable. Restoration of land and water resources is ranked as a priority in reclamation planning.

Energy
capacity to do work by performing mechanical, physical, chemical or electrical tasks or to cause a heat transfer between two objects at different temperatures.

usually refers to the ash released during the combustion of coal contains silicon dioxide (SiO2) and calcium oxide (CaO) as well as other chemicals
Half-life
the period of time it takes for the amount of a substance undergoing decay to decrease by half (A quantity of carbon-14 will decay to half of its original amount after 5730 years, regardless of how big or small the original quantity was.)
Hazardous Waste

takes in the hydrogen gas and separates the hydrogen atoms' electrons from their protons. The electrons flow through wires that collect the energy and the protons pass through membranes and combine with oxygen to from water vapor
Hubbert Peak (Peak oil)
M. king Hubbert's theory that rate of petroleum production in any geographical area, from individual oil producing regions to the planet as a whole, will follow a bell shaped curve. The US's peak was reached in 1970
Barrels
a unite of measuring oil (42 US gallons)
Remediation
Environmental remediation deals with the removal of pollution or contaminants from environmental media such as soil, groundwater, sediment, or surface water for the general protection of human health and the environment or from a brownfield site intended for redevelopment. Remediation is generally subject to an array of regulatory requirements, and also can be based on assessments of human health and ecological risks where no legislated standards exist or where standards are advisory.
Renewable Resource
a renewable resource can be replenished fairly quickly (from hours to hundreds of years) through natural processes as long as it is forests, grasslands, fisheries, freshwater, fresh air, and fertile soil.
Reservoir
As nutrients move through the biogeochemical cycles, they may accumulate in one portion of the cycle and remain there for different lengths of time. These temporary storage sites such as the atmosphere, the ocean and other wastes, and underground deposits are called reservoirs.
Scrubbers
devices containing alkaline substances that precipitate out much of the sulfur dioxide from industrial plants.
Second Law of Thermodynamics
In any conversion of heat energy to useful work, some of the initial energy input is always degraded to lower-quality (heat), more dispersed, less useful energy-usually low-temperature heat that flows into the environment; you cannot break even in terms of energy quality
Strip Mining
Form of surface mining in which bulldozers, power shovels, or stripping wheels remove large chunks of the earth's surface in strips
Subsidy
A subsidy is an assistance paid to a business or economic sector. Most subsidies are made by the government to producers or distributed as subventions in an industry to prevent the decline of that industry (e.g., as a result of continuous unprofitable operations) or an increase in the prices of its products or simply to encourage it to hire more labor (as in the case of a wage subsidy). Examples are subsidies to encourage the sale of exports; subsidies on some foods to keep down the cost of living, especially in urban areas; and subsidies to encourage the expansion of farm production and achieve self-reliance in food production
Subsurface Mining
Extraction of a metal ore or fuel resource such as coal from a deep underground deposit
Surface Mining
Removing soil, subsoil, and other strata and then extracting a mineral deposit found fairly close to the earth's surface
Synfuels
Synthetic gaseous and liquid fuels produced from solid coal or sources other than natural gas or crude oil
Tar sands
is a mixture of clay, sand, water, and a combustible organic material called bitumen-a thick and sticky, heavy oil with a high sulfur content that makes up about 10% of the gooey mixture
Thermal Energy
The total energy of a substance particles due to their movement or vibrations also the energy of motion in the molecules of a substance
Ultraviolet energy
Ultraviolet radiation is electromagnetic radiation or light having a wavelength greater than 10 nm but less than 400 nm. Ultraviolet radiation has a wavelength longer than that of x-rays but shorter than that of visible light. Ultraviolet is energetic enough to break some chemical bonds. Three types: A, B and C
Waste-to-energy
Waste-to-energy (WtE) or energy-from-waste (EfW) is the process of creating energy in the form of electricity or heat from the incineration of waste source. WtE is a form of energy recovery. Most WtE processes produce electricity directly through combustion, or produce a combustible fuel commodity, such as methane, methanol, ethanol or synthetic fuels
Underground Mining
Underground mining is used to extract coal that is deep beneath the surface or in seams exposed on hillsides. It involves drilling two openings called shafts into the coal bed-one to transport miners and equipment and the other to bring coal to the surface.

Passive Solar Collection
Harnesses the heat of the sun without using any moving parts or photochemical interaction.
