Electric energy consumption

Electric energy consumption is energy consumption in the form of electrical energy.[2] About a fifth of global energy is consumed as electricity: for residential, industrial, commercial, transportation and other purposes.[2] The global electricity consumption in 2022 was 24,398 terawatt-hour (TWh), almost exactly three times the amount of consumption in 1981 (8,132 TWh).[3] China, the United States, and India accounted for more than half of the global share of electricity consumption. Japan and Russia followed with nearly twice the consumption of the remaining industrialized countries.[3]

While power is measured in watts (W) or kilowatts (kW), energy consumption is typically measured in watt-hours (Wh) or kilowatt-hours (kWh).[4] The relationship is fundamental: energy (E) equals power (P) multiplied by time (t):[5]
