kW (KiloWatt) – One thousand (1,000) watts. A unit of measure of the amount of electricity needed to operate given equipment.
kWh (KiloWatt Hour) – The most commonly-used unit of measure to explain the amount of electricity consumed over time. It means one kiloWatt of electricity supplied for one hour.
