Cogeneration
The simultaneous production of electricity and useful heat from the same energy source.
ANWR (Arctic National Wildlife Refuge)
A region in Alaska with debated oil reserves, where drilling is controversial due to environmental concerns.
Nuclear Energy
Energy released from atomic reactions, primarily nuclear fission, used to generate electricity.
Uranium
A radioactive element used as fuel in nuclear reactors.
Half-life
The time required for half of a radioactive substance to decay.
Nuclear Fission
The process where atomic nuclei split, releasing energy.
U-238 (Uranium-238)
The most abundant uranium isotope, not easily fissionable but can be converted into plutonium-239.
Plutonium-239
A man-made radioactive isotope used in nuclear weapons and reactors.
U-235 (Uranium-235)
A naturally occurring isotope capable of sustaining a nuclear chain reaction.
Isotopes
Atoms of the same element with different numbers of neutrons.
Light Water Reactors (LWRs)
The most common type of nuclear reactor, using ordinary water as a coolant and moderator.
Nuclear Chain Reaction
A self-sustaining series of nuclear fissions, releasing energy.
Fuel Rods
Metal tubes containing nuclear fuel (usually uranium) used in reactors.
Fuel Pellets
Small cylindrical pieces of enriched uranium inside fuel rods.
Fuel Assembly
A bundle of fuel rods used in a nuclear reactor.

Containment Vessel
A structure designed to contain radiation and prevent leaks in case of an accident.
Spent Fuel Rods
Used nuclear fuel that remains highly radioactive and requires storage or reprocessing.
Decommission
The process of safely shutting down and dismantling a nuclear power plant.
Conventional Nuclear Fuel Cycle
The standard process of using uranium fuel, followed by disposal or reprocessing of waste.
High-Level Waste (HLW)
Highly radioactive materials from nuclear reactors, requiring long-term storage.
Nuclear Fusion
A reaction where atomic nuclei combine, releasing massive energy, but not yet viable for commercial power.
Bipartisan
Refers to different political parties that usually oppose each other's policies coming to agreement where necessary.
Buffer
(in this case a mountain) The mountains are buffers against multiple things such as erosion, noise, etc. Mountains also regulate local weather patterns.
Clean Water Act/Provisions- 1972
The framework for regulating the discharge of pollutants to all bodies of water = lakes, rivers, streams, and wetlands.
Coal Seams
Layers of coal embedded in sedimentary rock (coal is also sedimentary). 'Like a cake.'
Common Good
The good for all people - conditions that are equally to everyone's advantage.
Civil Disobedience
1) Break the Law, 2) Do it openly, 3) Accept the consequences, 4) Do it peacefully.
Fill Materials
Materials used to fill the areas that were mined. Usually soil, rock, and loose sediment.
Geology & Topography
Geology (in this context) refers to the history of events that led to seams of fossil fuels (Appalachia was once a region of massive swamps that were compressed due to intense pressure). Topography refers to hills, mountains, valleys and other characteristics of the terrain.
Heavy metals
(examples)- Lead, mercury, arsenic, nickel, (there are others, these are the ones mentioned in the film that are associated with coal).
Intrinsic value
The market value tells us the price that people are willing to pay for an asset (in this case a nonrenewable resource). Based on a resource's value vs. its actual financial performance.
Land Reclamation
According to the Reclamation Act of 1977, mining companies must post bond and have a plan for how they will ensure the land area that they are mining is put back to its original state.
Mountaintop Removal Mining
A type of coal mining where the layers above, between, and under coal seams. The layer above each coal seam is blasted off instead of drilled out. This is cheaper and easier to access than other forms of mining.
Overburden
The rock and/or soil layer that needs to be removed in order to access the desired ore material. Sometimes referred to as "spoil" or "waste rock."
Silica (relation to silicosis)
The small particles that remain suspended in the air from coal mining. Silicosis, a debilitating and potentially deadly lung disease, develops through inhalation of excessive concentrations of respirable crystalline silica dust.
Sludge Impoundments
Before being transported to market, coal must be washed to separate it from the surrounding soil and rock-the more impurities a company can remove from coal, the higher its market value and the lesser the transportation costs. The washing process generates huge volumes of liquid waste, while the mining process generates millions of tons of solid waste.

Sludge contains carcinogenic chemicals used to process coal. It also contains toxic heavy metals that are present in coal, such as arsenic, mercury, chromium, cadmium, boron, selenium, and nickel.
Subsidy
A sum of money granted by the government or a public body to assist an industry or business so that the price of a commodity or service may remain low or competitive.
Triple Bottom Line Approach
A way to evaluate the worth of something not just on its economic effect, but also on its environmental and social effects.
Negative Externality
A cost that is suffered by a third party as a consequence of an economic transaction. In a transaction, the producer and consumer are the first and second parties, and third parties include any individual, organization, property owner, or resource that is indirectly affected.
Externalities
Externalities are also referred to as spillover effects, and a negative externality is also referred to as an 'external cost'.
Soil Substitute
Refers to a material used to replace the natural topsoil removed during mining operations, often composed of amended mine waste, industrial byproducts like coal combustion slag, or other materials designed to support plant growth on reclaimed land.
Mine waste
Processed and amended mine tailings or waste rock, often requiring neutralization to manage acidity.

Coal combustion byproducts like fly ash or slag, which can be used to improve soil structure and nutrient content.
