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.

First law of Thermodynamics
in any physical or chemical change no energy can be created or destroyed, energy can be transferred from one for to another but you can not get more energy out of something than you put in

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
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.
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.
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.
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
Form of surface mining in which bulldozers, power shovels, or stripping wheels remove large chunks of the earth's surface in strips
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
Extraction of a metal ore or fuel resource such as coal from a deep underground deposit
Removing soil, subsoil, and other strata and then extracting a mineral deposit found fairly close to the earth's surface
Synthetic gaseous and liquid fuels produced from solid coal or sources other than natural gas or crude oil
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
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 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 (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 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.
(Wind farms) Large, utility-scale turbines grouped together into power plants and connected to the electrical utility grid; their power is sold to utility customers
Energy possessed by an object because of its motion; examples: light, heat, mechanical
A brownish-black fossil fuel that is used primarily for electric power generation. Considered to be a low-ranking type of coal. (aka brown coal)
The sum of energy in a mechanical system. This energy includes both kinetic energy, the energy of motion, and potential energy, the stored energy of position.

A natural resource such as coal, gas, or oil that, once consumed, cannot be replaced.
A nuclear reaction that splits the nucleus of an atom into smaller, subatomic particles. It often produces free neutrons and photons.
The process by which two or more atomic nuclei join together, or "fuse", to form a single heavier nucleus.
Passive Solar Collection
Harnesses the heat of the sun without using any moving parts or photochemical interaction.
Photovoltaic Cell (PV Cell)
Devices that produce electricity directly from sunlight. They convert light into electricity by harnessing the energy created when photons from sunlight knock electrons into a higher state of energy, within the cell itself.
The stored energy by any physical system, the standard unit for measuring this energy is the joule, example: chemical energy in sugar
A classification used in mining sectors that refers to the amount of resources that can be recovered from the deposit with a reasonable level of certainty.

Oil Sands (Tar Sands)
Oil reserve which are part of a natural mix of sand or clay, water, and a type of oil known as bitumen. (Process of extracting oil from tar sands is expensive, but when oil prices rise, considered more seriously for large-scale extractions)

Those acting on economic actors from outside the market system. They include internal and external organizing and correcting factors that provide order to market and other types of societal institutions and organizations - economic, political, social and cultural - so that they may function efficiently and effectively as well as repair their failures.
