Global Energy Review 2026
The report covers estimates of energy demand by region and by source and fuel in 2025; developments in electricity demand and supply; deployment of selected energy technologies; and estimates of energy-related CO2 emissions. The report also assesses trends in energy intensity and analyses the impact of factors, such as weather effects, on energy demand and emissions.
Key findings are:
All major energy fuels and technologies grew in 2025 – but at very different rates. Overall global energy demand growth slowed to 1.3%, just below the average for the previous decade. Slower economic growth and slower growth in energy-intensive industries in some regions, lower cooling demand, and faster efficiency improvements all contributed to slower demand growth.
Solar PV, the largest single source of growth, met more than 25% of higher demand, followed by natural gas, which contributed 17%. This was the first time on record that a modern renewable source contributed the largest share of global energy demand growth. Demand for oil, natural gas and coal all grew in 2025, but at a slower rate than in 2024. Low-emissions sources combined – solar, wind, nuclear, hydropower and other renewables – contributed nearly 60% of the growth in global demand.
Demand growth in the United States rose to its second highest level since 2000, excluding post-recession rebound years, boosted by strong electricity demand from data centres, robust industrial growth and colder temperatures. The People’s Republic of China (hereafter, “China”) accounted for the largest overall share of global energy demand growth, but at 1.7% its growth rate slowed sharply due to the rapid growth of renewables and efficiency improvements.
Demand for electricity grew at well over twice the rate of energy demand, reaffirming that the world has entered the Age of Electricity. Growth of nearly 3% remained above the average of 2.8% over the last decade, but was slower than in 2024, largely due to one-off factors such as lower demand for cooling in India and Southeast Asia. Electricity demand growth was again driven by a wide range of end uses in buildings and industry. Although only contributing a small share of this total growth, demand from electric vehicles and data centres grew rapidly. In the United States, data centres made up half of all growth in electricity use.
Oil demand growth slowed further in 2025, increasing by 0.65 million barrels per day (mb/d) or 0.7%, down from 2024’s already muted 0.75 mb/d of growth. The increase in both years, which was in line with IEA projections, remained well below the average annual rise between 2010 and 2019 of 1.4 mb/d. The slower increase mainly reflected weaker growth in petrochemical feedstocks, notably in China, while continued growth of electric vehicles kept oil demand for road transport in check. Electric car sales continued their rapid growth, climbing over 20% to more than 20 million units – around one quarter of new car sales in 2025.
Gas demand growth slowed markedly in 2025, rising by around 1%, down from the 2.8% recorded in 2024, amid relatively high prices in the first half of the year. Incremental demand was largely concentrated in the United States and European Union, supported by colder winter weather, and in the Middle East, where gas use in the power sector grew quickly. By contrast, Asia Pacific demand grew at its weakest pace since the 2022 energy crisis.
Coal demand in 2025 grew only modestly above 2024 levels, rising by around 0.4%. In the United States, gas-to-coal switching and strong growth in electricity demand supported a 10% rise in coal use, reversing the trend of recent declines. Coal demand was flat in China: strong renewables growth pushed down coal use in electricity generation, while in industry, lower coal use in steel and cement production was offset by increased use for chemicals. Coal demand for power generation decreased in India, mostly due to an early, strong and long monsoon.
The increase in generation from renewables and nuclear power in 2025 exceeded the total growth in electricity supply. The 2025 increase in solar PV of 600 terawatt-hours (TWh) was the largest-ever electricity generation increase by any source in one year, outside of periods of post-crisis recovery. The rise in solar PV alone met around 70% of electricity generation growth. Renewables combined now virtually match total global generation from coal. In the European Union, the share of solar PV and wind reached 30% in 2025, surpassing that of fossil fuels for the first time. Electricity generation from natural gas and from nuclear power continued to grow at the global level in 2025.
Annual global renewable capacity additions rose to a record 800 gigawatts (GW), of which solar contributed 75%. Battery storage was the fastest growing power technology: capacity additions rose by around 40% in 2025 to reachalmost 110 GW, more than the highest-ever annual capacity additions from natural gas. In addition, construction started on over 12 GW of nuclear power capacity in 2025.
Global growth in energy-related carbon dioxide emissions slowed further in 2025, rising by around 0.4%. Emissions from China fell due to the boom in renewables, structural declines in energy-intensive industry, and overall slower demand growth. India’s energy-related CO2 emissions were flat for the first time since the 1970s, largely due to cyclical effects from a strong monsoon combined with structural growth in renewables. A cold winter and higher natural gas prices pushed up emissions in advanced economies. Due to these trends, emissions from advanced economies grew faster (+0.5%) than those from emerging market and developing economies (+0.3%) for the first time since the 1990s.
The rollout of clean energy technologies since 2019 avoided more than 35 exajoules of annual fossil fuel demand in 2025, equivalent to around 7% of global fossil fuel use annually. Deployment of solar PV, wind, nuclear, electric cars and heat pumps since 2019 also prevents 3 billion tonnes of CO2 annually, or around 8% of global emissions. The avoided coal demand (around 800 million tonnes of coal equivalent) equates to more than the entire coal use of India in 2025. Estimated avoided gas demand (over 260 billion cubic metres) is equivalent to almost half the global liquefied natural gas (LNG) market.
