Power (word): An English word over-loaded with meanings in several different domains of knowledge. [e]
Economics
- Market power: The ability of a supplier to exercise a degree of choice concerning the pricing of a product by restricting its supply: a measure of departure from the ideal of perfect competition in which every supplier is a price-taker [e]
Engineering
- Explosive power: The total power available from an explosive, measured with various tests of its ability to move mass rather than shatter it [e]
- Overhead power line: A power line installed above ground, on series of dedicated poles or towers, from which the line is suspended. [e]
Energy
Electrical power plant: An umbrella term for facilities to generate electric power, usually on an industrial scale. [e]- Geothermal power: Extracts energy from the heat stored beneath the Earth's surface and uses it for space heating or for generating electricity; see the Geothermal power article on Wikipedia for details. [e]
- Nuclear power: Add brief definition or description
- Solar power: Energy sources based directly on the sun's electromagnetic radiation. [e]
- Tidal power: Energy flows associated with tidal action. Some sources posit it to be an important alternative energy source. [e]
- Wind power: Uses turbines inside wind mills to generate electricity or pump water or do other work; see the Wind power article Wikipedia for details. [e]
Types of electrical generation plants using coal
- Conventional coal-fired power plant: power plant that burns coal in a steam generator to produce high pressure steam, which goes to steam turbines that generate electricity. [e]
- Oxygen firing power plant: a.k.a. Oxy firing plant, works like a conventional coal-fired power plant but uses oxygen instead of air to burn the coal; see the Oxy-fuel combustion process article on Wikipedia [e]
- Integrated gasification combined cycle power plant: a.k.a. IGCC; uses coal to produce a synthetic gas that is burned to drive an electrical generator, while produced steam is used to drive another generator. See the Integrated gasification combined cycle article on Wikipedia. [e]
- Fluidized bed combustion power plant: burns coal in a fluidized bed; steam produced as a by-product also drives an electrical generator; see the Fluidized bed combustion article on Wikipedia [e]
Types of electrical generation plants not using coal
- Biomass power plant: An electrical power plant which produces electricity by burning biomass solids in a steam generator that heats water, which is then used to generate electricity. [e]
- Geothermal power plant: An electrical power plant that extracts heat energy stored beneath Earth's surface and uses it to generate electricity. [e]
- Hydroelectric power plant: An electrical power plant that generates electric power by converting the energy in falling or flowing water into electricity; water is directed through turbines which spin to generate electricity. [e]
- Nuclear power plant: A power plant, often electric, that uses the energy derived from controlled (non-explosive) nuclear reactions to generate electricity. Conventionally, nuclear power plants used the heat energy derived from nuclear fission to generate steam, which in turn generates electric power. [e]
- Oxygen firing power plant: a.k.a. Oxy firing plant, works like a conventional coal-fired power plant but uses oxygen instead of air to burn the coal; see the Oxy-fuel combustion process article on Wikipedia [e]
- Solar power plant: An electrical power plant that generates electricity directly from sunlight either by using photovoltaics or by focusing solar radiation into a concentrated beam of heat that is used to generate steam for conversion into electric power. [e]
- Thermal power plant: An electric power plant in which all of the electricity is produced by using a heat source to generate steam that drives a steam turbine which rotates an electrical generator. [e]
History
- Great power: A nation state able to exercise influence on a global scale. In the long century after 1815, the term was generally applied to the most powerful European nations. After World War II, the designation of permanent members of the United Nations Security Council was an expression of prevailing great powers. [e]
Slave Power: Add brief definition or description
Mathematics and statistics
- Power function: A function in which the argument is raised to a (constant-value) exponent. [e]
- Power series: An infinite series whose terms involve successive powers of a variable, typically with real or complex coefficients. [e]
- Power set: The set of all subsets of a given set. [e]
- Power (statistics): Add brief definition or description
Media
People
- Samantha Power: Special adviser for human rights, National Security Council staff in the Obama Administration; Pulitzer-prize journalist specializing in genocide [e]
Physics
- Power (physics): Rate of producing or consuming energy; SI unit: watt = joule/second. [e]
Politics
- Power (politics): The capacity to control the administration of resources within a society [e]
- Balance of power: The policy of forming alliances in order to counter the military power of a dominant country. [e]
- Occupying power: A formal legal concept from the Geneva Conventions, referring to nation-state(s) that have effective control of, and responsibility for, a conquered area [e]
- Regional power: In international relations, a nation whose power is restricted primarily to its own geographic region. [e]
- Power projection: The capability to deploy military forces, even if limited to air and special operations, on short notice over intercontinental ranges [e]
- Prerogative power: A legal doctrine that empowers a head of state or government to act beyond the laws of a nation, when the supreme national interests of that nation are involved [e]
- Social power: A social theory by French and Raven, postulates that there are six sources of social power: reward; coercion; legitimacy or normative power; referent (or organizational) power; expertise and information. [e]
