    Acronym(s): kWh

    A measure involving one thousand watts being generated, transmitted, distributed or used continuously for one hour. The kiloWatt-hour is perhaps the most common unit of electric energy; it is used by utilities for billing. (Note the difference between kiloWatt-hours of energy and a kilowatt of power where power reflects the rate at which electric energy is generated, transmitted, distributed or used).
