  2. Electrical energy - Wikipedia

    en.wikipedia.org/wiki/Electrical_energy

    Electrical energy is energy related to forces on electrically charged particles and the movement of those particles (often electrons in wires, but not always). This energy is supplied by the combination of current and electric potential (often referred to as voltage because electric potential is measured in volts) that is delivered by a circuit (e.g., provided by an electric power utility).

  4. Electricity - Wikipedia

    en.wikipedia.org/wiki/Electricity

    Electric utilities measure power using electricity meters, which keep a running total of the electric energy delivered to a customer. Unlike fossil fuels , electricity is a low entropy form of energy and can be converted into motion or many other forms of energy with high efficiency.

  6. Electric potential - Wikipedia

    en.wikipedia.org/wiki/Electric_potential

    In short, an electric potential is the electric potential energy per unit charge. This value can be calculated in either a static (time-invariant) or a dynamic (time-varying) electric field at a specific time with the unit joules per coulomb (J⋅C −1) or volt (V). The electric potential at infinity is assumed to be zero.

  7. Electric power industry - Wikipedia

    en.wikipedia.org/wiki/Electric_power_industry

    Generation is the conversion of some primary energy source into electric power suitable for commercial use on an electrical grid. Most commercial electric power is produced by rotating electrical machines, " generators ", which move conductors through a magnetic field to produce electric current.

  8. Electric power - Wikipedia

    en.wikipedia.org/wiki/Electric_power

    Electric power is the rate of transfer of electrical energy within a circuit.Its SI unit is the watt, the general unit of power, defined as one joule per second.Standard prefixes apply to watts as with other SI units: thousands, millions and billions of watts are called kilowatts, megawatts and gigawatts respectively.

  9. Steam–electric power station - Wikipedia

    en.wikipedia.org/wiki/Steam–electric_power_station

    The efficiency of a conventional steam–electric power plant, defined as energy produced by the plant divided by the heating value of the fuel consumed by it, is typically 33 to 48%, limited as all heat engines are by the laws of thermodynamics (See: Carnot cycle). The rest of the energy must leave the plant in the form of heat.
