The International Energy Agency (IEA) in its Electricity Mid-Year Update reports that global electricity demand is set to rise by 3.3% in 2025 and 3.7% in 2026 – more than twice as fast as total energy demand growth over the same period.
The new report underscores the increasing demand for electricity to power factories and appliances, keep buildings cool, operate growing fleets of data centres, run electric vehicles and more.
While the latest forecasts for global electricity demand growth this year and next are a deceleration from the 4.4% surge recorded in 2024, they remain well above the 2015-2023 average of 2.6%.
Renewables are expected to overtake coal as the world’s largest source of electricity as early as 2025 or by 2026 at the latest, depending on weather and fuel price trends.
At the same time, nuclear power output is expected to reach record highs, driven by reactor restarts in Japan, robust output in the United States and France, and new additions, mostly in Asia.
The steady increase in gas-fired power generation is set to continue displacing coal and oil in the power sector in many regions.
As a result of these developments, carbon dioxide emissions from electricity generation are currently forecast to plateau in 2025 and record a slight decline in 2026, although weather and economic conditions could affect that trajectory.
“The growth in global electricity demand is set to remain robust through 2026, despite an uncertain economic backdrop,” said Keisuke Sadamori, IEA Director of Energy Markets and Security. “
