Large-scale electricity transmission usually uses alternating current, in which both current and voltage oscillate.

ECONOMIST: Superconductors are starting to become useful

At 400 kilovolts, a standard value for long-distance transmission, an alternating current 30 metres (100 feet) from the ground has a fortieth of the loss of a similar cable at ground level.
