power consumption Definition. The rate at which power is consumed by a device or unit (such as a building), usually expressed in kilowatt-hours, Btu/hour, or horsepower-hours.
Another term that is useful in this discussion is power factor (PF). The power factor is defined as the ratio of W to VA: Power factor = PF = W/VA (5) Power factor is always a number between zero and one because the watts drawn by a device are always less than or equal to the volt-amperes.
