Electric energy consumption

Electricity consumption by region. By 2025, Asia is projected to account for half of the world’s electricity consumption, with one-third of global electricity to be consumed in China.

Electric energy consumption is energy consumption in the form of electrical energy. Approximately one-fifth of global energy is consumed as electricity: for residential, industrial, commercial, transportation and other purposes. The global electricity consumption in 2022 was 24,398 terawatt-hours (TWh), almost exactly three times the amount of consumption in 1981 (8,132 TWh). 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.

While power is measured in watts (W) or kilowatts (kW), energy consumption is typically measured in watt-hours (Wh) or kilowatt-hours (kWh), following the fundamental relation:

where E is energy, P is power, and t is time.
