How this measure is built
- Definition
- Annual electricity consumed by all data centres globally, not AI-only facilities; April 2026 historical estimate or central projection.
- Measure
- One slice of Electricity consumption ( form: level, segment: data centre ) . Total electrical energy consumed over a given period. Region and period are columns on every record, not slices.
- Limitations
- 1 figure is a projection, drawn dashed and labelled in the table. Values are shown as published; StatOrigin does not revise, fill gaps or convert currencies.
- Verification
- Each value, unit, period and place was checked against its source evidence before publication. See the methodology and the corrections process.
