QAZAQ GREEN.  Global energy demand reached an all-time high in 2025, with renewables becoming the largest source of energy supply growth for the first time outside of a recession, and regional energy transition pathways diverging sharply. These are among the key findings of the 75th edition of the Statistical Review of World Energy, published by the Energy Institute in partnership with Ember, KPMG and Kearney.

Total energy supply rose 1.7%, with all major energy sources reaching record levels for the second consecutive year. Solar generation expanded by 30% worldwide, accounting for 71% of the increase in renewables, while battery storage capacity grew by 66%.

For the first time on record, the 3% year-on-year growth in global electricity demand was met entirely by low-carbon sources, with renewables and hydro overtaking coal as the largest source of electricity generation globally.

The regional picture, however, remains sharply divided. China delivered record wind and solar additions while keeping emissions growth to just 0.3%. India expanded renewable generation by nearly 24%, with emissions rising 0.9%. The United States recorded the largest emissions increase among major economies at 3.2%, driven by a 13% surge in coal-fired power.

In a first for the Review, global electricity consumption by data centres was reported at 788 TWh, with 40% concentrated in the United States.
