  2. Power supply - Wikipedia

    en.wikipedia.org/wiki/Power_supply

    A power supply is an electrical device that supplies electric power to an electrical load. The main purpose of a power supply is to convert electric current from a source to the correct voltage, current, and frequency to power the load. As a result, power supplies are sometimes referred to as electric power converters. Some power supplies are ...

  4. World energy supply and consumption - Wikipedia

    en.wikipedia.org/wiki/World_energy_supply_and...

    Total final consumption (TFC) is the worldwide consumption of energy by end-users (whereas primary energy consumption (Eurostat) [24] or total energy supply (IEA) is total energy demand and thus also includes what the energy sector uses itself and transformation and distribution losses). This energy consists of fuel (78%) and electricity (22%).

  5. Electricity - Wikipedia

    en.wikipedia.org/wiki/Electricity

    Electric power is the rate at which electric energy is transferred by an electric circuit. The SI unit of power is the watt, one joule per second. Electric power, like mechanical power, is the rate of doing work, measured in watts, and represented by the letter P. The term wattage is used colloquially

  6. Electric power distribution - Wikipedia

    en.wikipedia.org/wiki/Electric_power_distribution

    Electric power distribution is the final stage in the delivery of electricity. Electricity is carried from the transmission system to individual consumers. Distribution substations connect to the transmission system and lower the transmission voltage to medium voltage ranging between 2 kV and 33 kV with the use of transformers. [1]

    Between 2006 and 2022, the US has gone from net importing 4 quads of natural gas to exporting 4 quads. [26] The United States has been the world's largest producer of natural gas since 2011, when it surpassed Russia. However, the US ranks 7th in proven reserves. [4] Differences in supply explain why gas is cheaper in the US than it is in Europe ...

    By 2028, data centers' annual energy use could reach between 74 and 132 gigawatts, or 6.7% to 12% of total U.S. electricity consumption, according to the Berkeley Lab report.

  9. Units of energy - Wikipedia

    en.wikipedia.org/wiki/Units_of_energy

    A unit of electrical energy, particularly for utility bills, is the kilowatt-hour (kWh); [3] one kilowatt-hour is equivalent to 3.6 megajoules. Electricity usage is often given in units of kilowatt-hours per year or other periods. [4] This is a measurement of average power consumption, meaning the average rate at which energy is transferred ...
