While the state of modern world might suggest AC is the winner, DC is not dead yet.

. Higher voltages allowed the electricity to be transmitted for longer distances, which is why alternating current was, and still is, preferred for use by power distribution companies worldwide.

Alternating current can also be found in AC motors, a kind of electric motor that relies on alternating current to turn the movement of electrons into mechanical energy. The most common uses of AC motors are in hydraulic pumps, fans, air conditioners, and conveyor systems. Direct current can also be used to power electric motors. DC motors are often used in elevators, vacuums, sewing machines, tools, electric vehicles, flashlights, and small appliances.

Direct current couldn’t compete with that. The lack of practical methods to convert it to high voltages made it necessary to reduce the transmission range of the energy. This forced the companies that bet on DC to build local power plants, just around one mile away from the end-user at most, which meant higher costs and that rural areas were left out.
