The unit used to measure electrical energy consumption is?

Energy consumption is measured in kilowatt-hours because it reflects how much energy is used over time (energy equals power times time). A watt is the unit of power, indicating the rate at which energy is used, not the total amount. Volts measure electrical potential difference, and ohms measure resistance; neither directly represents the amount of energy consumed. To bill energy usage, utilities use kilowatt-hours, such as: a device rated at 100 watts running for 5 hours uses 100 W × 5 h = 500 Wh = 0.5 kWh.
