Electricity consumptionThe demand for electricity has increased massively in the past four decades as it has become more and more important in our lives. Rising populations, economic growth, and increasing demand for consumer electronics has seen global electricity consumption rise from 7,323 terawatt hours in 1980 to more than 22,000 terawatt hours in 2019. Electricity demand is projected to continue growing in the coming decades and is expected to have surpassed 35,000-terawatt hours by 2040.
Today, China and the United States are far and away the largest consumers of electricity worldwide. Combined, the two superpowers account for roughly 50 percent of global electricity consumption, though the U.S. consumes considerably more than China per capita. In 2018, Canada had the highest electricity consumption per capita worldwide, at 15,438 kilowatt hours.
