  2. Electric power transmission - Wikipedia

    en.wikipedia.org/wiki/Electric_power_transmission

    Electricity is transmitted at high voltages to reduce the energy loss due to resistance that occurs over long distances. Power is usually transmitted through overhead power lines . Underground power transmission has a significantly higher installation cost and greater operational limitations, but lowers maintenance costs.

  3. World Wireless System - Wikipedia

    en.wikipedia.org/wiki/World_Wireless_System

    The Wardenclyffe Power Plant prototype, intended by Nikola Tesla to be a "World Wireless" telecommunications facility.. The World Wireless System was a turn of the 20th century proposed telecommunications and electrical power delivery system designed by inventor Nikola Tesla based on his theories of using Earth and its atmosphere as electrical conductors.

  4. History of electric power transmission - Wikipedia

    en.wikipedia.org/wiki/History_of_electric_power...

    Electric power transmission, the tools and means of moving electricity far from where it is generated, date back to the late 19th century. They include the movement of electricity in bulk (formally called "transmission") and the delivery of electricity to individual customers ("distribution"). In the beginning, the two terms were used ...

  5. Wireless power transfer - Wikipedia

    en.wikipedia.org/wiki/Wireless_power_transfer

    In contrast, with wireless power transfer the amount of energy received is the important thing, so the efficiency (fraction of transmitted energy that is received) is the more significant parameter. [13] For this reason, wireless power technologies are likely to be more limited by distance than wireless communication technologies.

  6. Smart grid - Wikipedia

    en.wikipedia.org/wiki/Smart_grid

    "It is the policy of the United States to support the modernization of the Nation's electricity transmission and distribution system to maintain a reliable and secure electricity infrastructure that can meet future demand growth and to achieve each of the following, which together characterize a Smart Grid: (1) Increased use of digital ...

  7. Electric power industry - Wikipedia

    en.wikipedia.org/wiki/Electric_power_industry

    The electric power industry is commonly split up into four processes. These are electricity generation such as a power station, electric power transmission, electricity distribution and electricity retailing. In many countries, electric power companies own the whole infrastructure from generating stations to transmission and distribution ...

  8. Electrical grid - Wikipedia

    en.wikipedia.org/wiki/Electrical_grid

    Energy from fossil or nuclear power plants and renewable sources is stored for use by customers. Simplified grid energy flow over the course of a day. Grid energy storage (also called large-scale energy storage) is a collection of methods used for energy storage on a large scale within an electrical power grid.

  9. 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]
