Global electricity mix 2023, by energy source

Fossil fuels remain the greatest source of electricity generation worldwide. In 2023, coal accounted for roughly 35.5 percent of the global power mix, while natural gas followed with a 23 percent share. China, India, and the United States accounted for the largest share of coal used for electricity generation. 

The future of renewable energy

Fossil fuel use notwithstanding, the share of renewables in global electricity has seen a more pronounced year-on-year growth in recent years, following increased efforts by governments to combat global warming and a decrease in levelized costs. Projections indicate that renewables will surpass fossil fuels as the main power source by 2040.

Electricity consumption in the world

China is the largest electricity consumer in the world, requiring more than 8,000 terawatt-hours of electricity every year. However, this economic power accounts for the largest population in the world and its electricity consumption per capita is almost tenfold smaller than the consumption of Iceland, although the power used in this country came almost completely from clean sources.
