Power consumption

Power consumption

In electrical engineering, power consumption often refers to the electrical energy over time supplied to operate an electrical appliance, although this is, strictly speaking, energy. The energy consumed by equipment that is less than 100% efficient includes wasted power that is dissipated as heat, vibration and/or electromagnetic radiation.

Power consumption is usually measured in units of kilowatt hours (kWh) using a kWh or electric meter.

More accurately, power is the rate of consumption of energy, measured in watts or horsepower.
