How much will global electricity demand rise by 2035?
Core argument: The World Energy Outlook 2025 projects electricity demand rising around 40–50% by 2035, though electricity accounts for only 21% of total final consumption while serving sectors making up over 40% of the global economy.
Electricity rises by around 40% to 50% by 2035. End-use electrification already accounts for half of today’s global energy investment. For the moment, electricity accounts for only 21% of total final consumption globally, but it is the key source of energy for sectors accounting for over 40% of the global economy and the main source of energy for most households. Driven by surging data centre expansion, electricity consumption by AI-optimised servers increases fivefold by 2030, due to a doubling of total electricity consumption by data centres by 2030. [Yet] data centres account for less than 10% of global electricity demand growth between 2024 and 2030. Cooling is a rising source of electricity demand, led by developing economies. In [one scenario] income-driven air conditioning use adds around 330 GW to global peak demand by 2035, and higher temperatures add another 170 GW. Since 2000, coal has been the fastest growing fossil fuel in the global energy mix. Global coal demand has nearly doubled since then, and reached the record level of 6,090 million tonnes of coal equivalent (Mtce) in 2024, driven mainly by the use of coal to generate power in emerging market and developing economies, in particular China and India. Global coal demand peaks before 2030 and by 2035, demand is around 8% lower than 2024 levels.
