Electricity demand drove a jump in overall global energy consumption growth in 2024, lifting it well above the average pace of increase in recent years, energy watchdog the IEA said today.
Global energy demand rose by 2.2pc in 2024 — higher than the average annual demand increase of 1.3pc between 2013 and 2023 — according to the Paris-base agency's Global Energy Review. Global electricity consumption rose by 4.3pc, driven by record-high temperatures that led to increased cooling demand, growing industrial consumption, the electrification of transport and from data centres and artificial intelligence, the IEA said.
Renewables and nuclear covered the majority of growth in electricity demand, at 80pc, while supply of gas-fired power generation "also increased steadily", it said. New renewable power capacity installations reached around 700GW in 2024 — a new high — while renewable power sources and nuclear together made up 40pc of total generation in 2024, it said.
Global gas demand rose by 2.7pc in 2024, with an increase in "fast growing Asian markets", the IEA said. It noted growth of more than 7pc and 10pc in China and India, respectively.
But "growth in global oil demand slowed markedly in 2024", the organisation said. Oil demand rose by 0.8pc — compared with 1.9pc in 2023 — and oil's share of total energy demand fell below 30pc last year "for the first time ever".
A rise in electric vehicle (EV) purchases was a key contributor to the drop in oil demand for road transport, and this offset "a significant proportion" of the rise in oil consumption for aviation and petrochemicals, the IEA said.
The rate of increase in coal demand slowed to 1.1pc in 2024, half the pace seen in 2023.
"Intense heatwaves" in China and India "contributed more than 90pc of the total annual increase in coal consumption globally", for cooling needs, the IEA found.
Renewables limit rise in emissions
The IEA repeatedly noted the significant effect that extreme weather in 2024 had on energy systems and on demand patterns. Last year was the hottest ever recorded, beating the previous record set in 2023.
"Weather effects contributed about 15pc of the overall increase in global energy demand", the IEA said. Global cooling degree days were 6pc higher in 2024 on the year, and 20pc higher than the 2000-20 average, it said.
But the "continued rapid adoption of clean energy technologies" restricted the rise in energy-related CO2 emissions, which fell to 0.8pc in 2024 from 1.2pc in 2023, the IEA said. Energy-related CO2 emissions still hit a record high of 37.8bn t in 2024, but the rise in emissions was lower than global GDP growth, it said.
"The majority of emissions growth in 2024 came from emerging and developing economies other than China," the IEA said. Emerging and developing economies accounted for more than 80pc of the increase in global energy demand last year, it said.
