New York, 11 November 2026 – Global electricity demand from data centres could nearly quadruple to 2,354 terawatt-hours by 2035, equivalent to 7% of projected world electricity use, according to the new Powering the Data Center Boom study.

For developers and investors, the commercial and environmental case depends on what supplies the additional demand, how quickly new generation comes online and what it costs to use the network.
