Overview

Defining Electric Energy

Electric energy consumption refers to the utilization of electrical energy across various applications. Globally, electricity accounts for approximately one-fifth of total final energy consumption, serving residential, industrial, commercial, transportation, and other sectors.^[2]

Units of Measurement

While power is measured in watts (W) or kilowatts (kW), energy consumption is quantified in watt-hours (Wh) or kilowatt-hours (kWh). The fundamental relationship is Energy = Power × Time (E=P×t).^[4]^[5] Electric energy is also measured in joules (J), where 1 W·s = 1 J, and 1 kWh = 3.6 million J.^[6]

Historical Context

The generation of electricity in power stations began in 1882. The subsequent development of the steam turbine in 1884, used to drive electric generators, significantly spurred the increase in worldwide electricity consumption.^[8]^[9]

Global Consumption Trends

Consumption Growth

Global electricity consumption in 2022 reached approximately 24,398 terawatt-hours (TWh), nearly tripling the 8,132 TWh consumed in 1981. This indicates a substantial and sustained increase in electricity demand over four decades.^[3]

Leading Consumers

China, the United States, and India collectively account for over half of the global electricity consumption. Japan and Russia follow, with consumption levels significantly higher than other industrialized nations.^[3]

Sectoral Distribution

In 2022, the industrial sector was the largest consumer of electricity, accounting for 42.2% of total final consumption. The residential sector followed at 26.8%, with commercial and public services at 21.1%. The transport sector represented a smaller portion (1.8%), while agriculture and other uses comprised the remainder (8.1%).^[12]

Per Capita Consumption

Regional Disparities

Per capita electricity consumption varies significantly worldwide. Developed regions like Scandinavia, North America, Japan, and the UK exhibit higher per capita usage, often exceeding 10 MWh annually. Conversely, many developing nations show much lower consumption levels, with some populations lacking grid access.^[10] The global average in 2022 was approximately 3 MWh per person.^[10]
