• Electricity 4.92 MWh (4.07 MWh to 5.84 MWh)
• Water 12,492 litres (489 litres to 32,004 litres)
• CO2 2.33 tonnes (509 kg to 3.27 tonnes)

AI runs at about 17.7 GW, day and night, about 5.81 times the data centres of Northern Virginia, the biggest hub Hum tracks (about 3,046 MW). At this rate AI fills an Olympic pool (2.5 million litres) with the water it uses about every 3.34 minutes.

A model, not a live meter: the world's data-centre electricity in 2025 (IEA) times AI's share (26.5–38%, a United States figure used as a world estimate), spread evenly over the year. Water: on-site cooling plus power-plant water per kWh. CO2: world-average grid (middle). Dotted numbers are calculated. How we know
