What the Data Shows
Global data center electricity demand in the IEA 2030 Base Case is compared with selected national electricity-use benchmarks. The chart uses four TWh-per-year bars: global data centers in 2030 and Japan, Germany and India electricity use from 2023 or 2024 sources. At 945 TWh, the IEA data center figure is about 1.01x Japan’s benchmark and 1.79x Germany’s benchmark. India’s benchmark is larger at 1,715 TWh, so the data center figure is 55.1% of India’s electricity-use comparison value.

| 1 | Global data centers (2030) | 945 TWh | 2030 |
| 2 | Japan electricity use (2024) | 934 TWh | 2024 |
| 3 | Germany electricity use (2024) | 527 TWh | 2024 |
| 4 | India electricity use (2023-24) | 1,715 TWh | 2023-2024 |

Data notes & caveats
This is a raw benchmark comparison with mixed national definitions and periods. Japan and India use World Bank per-capita electricity and population inputs, while Germany uses gross electricity consumption.
Methodology
Japan and India TWh benchmarks use per-capita electricity consumption multiplied by population and divided by one billion. Germany uses the AGEB gross electricity consumption value directly.
Source consistency notes
The anchor is IEA, while benchmark rows use World Bank and AGEB. Units are harmonized to TWh, but definitions and periods are mixed.
