Electrical energy is generated by power plants and is then sold as a commodity to end consumers by retailers. The electric energy transmission and electricity distribution networks allow the delivery of the generated electricity to consumers. The rapid industrialization in the 20th century made electrical transmission lines and grids a critical part of the economic infrastructure in most industrialized nations.
