Data-centre electricity
International Energy AgencyEurope, as the IEA defines it
- 2024 estimated 70 TWh · slightly less than 2% IEA 2025, p. 58
Data centres account for slightly less than 2% of Europe’s electricity consumption, a share that is higher than China’s (1.1%). However, in absolute terms, Europe’s consumption is lower, at an estimated 70 TWh in 2024.
- Change, 2024 to 2030 more than +45 TWh IEA 2025, p. 64
Consumption increases by around 240 TWh (up 130%) in the United States, compared to the 2024 level (Figure 2.12). In China it increases by around 175 TWh (up 170%). In Europe it grows by more than 45 TWh (up 70%). Japan increases by around 15 TWh (up 80%).
- 2030, base case around 115 TWh IEA 2026, p. 64
This is comparable to the projected future demand from data centres in Europe, which is projected to grow to around 115 TWh, accounting for approximately 12% of global demand.
