Materials left over from making nuclear energy. Radioactive waste can destroy living organisms if it is not stored safely.
Industry:Energy
The use of solar thermal energy or solar electricity to power a cooling appliance. There are five basic types of solar cooling technologies absorption cooling, which can use solar thermal energy to vaporise the refrigerant; desiccant cooling, which can use solar thermal energy to regenerate(dry) the desiccant; vapour compression cooling, which can use solar thermal energy to operate a Rankine-cycle heat engine; and evaporative coolers ("swamp" coolers), and heat-pumps and air conditioners that can be powered by solar photovoltaic systems.
Industry:Energy
Company that operates a coal mining operation and is owned by another company (i.e., the parent company).
Industry:Energy
The spontaneous emission of radiation from the nucleus of an atom. Radionuclides lose particles and energy through this process.
Industry:Energy
The apparent angle of the sun north or south of the earth's equatorial plane. The earth's rotation on its axis causes a daily change in the declination.
Industry:Energy
Underground mining methods. A technique that long sections of coal, up to about 700 feet, are removed and no pillars are left to support the mined-out areas. The working area is protected by a movable, powered roof support system. The caved area (gob) compacts and, after initial subsidence, supports the overlying strata. Longwall mining is used where the coalbed is thick and generally flat, where surface subsidence is acceptable.
Industry:Energy
A unit that is in operation at the beginning of the reporting period.
Industry:Energy
The radiant energy of the sun, which can be converted into other forms of energy, such as heat or electricity.
Industry:Energy
Underground mining methods. Generally refers to the room-and-pillar mining in which the working face is wider than usual but smaller (less than 150 feet) than that in longwall mining.
Industry:Energy
Represents the use of the atmospheric crude oil distillation units. The rate is calculated by dividing the gross input to these units by the operating refining capacity of the units.
