Single-wire Earth Return
Single wire earth return (SWER) or single wire ground return is a single-wire transmission line for supplying single-phase electrical power from an electrical grid to remote areas at low cost. Its distinguishing feature is that the earth (or sometimes a body of water) is used as the return path for the current, to avoid the need for a second wire (or neutral wire) to act as a return path. It is principally used for rural electrification, but also finds use for larger isolated loads such as water pumps, and light rail. Single wire earth return is also used for HVDC over submarine power cables.

Famous quotes containing the words earth and/or return:
“My darling girl, Unfortunately this earth is not ... a fairy- land, but a struggle for life, perfectly natural and therefore extremely harsh. All the same, or precisely for this reason, it is happiness and comfort for us men to have a precious sweetheart—and I have the most precious, the dearest and best of all!”
—Martin Bormann (1900–1945)
“Love is life. All, everything that I understand, I understand only because I love. Everything is, everything exists, only because I love. Everything is united by it alone. Love is God, and to die means that I, a particle of love, shall return to the general and eternal source.”
—Leo Tolstoy (1828–1910)
