By 2030, the world’s data centres may use about as much electricity in a year as the entire nation of Japan uses today.
“Thousands of data centres are set to be built in the next five years.”
At that total, data centres would account for around 3% of global electricity demand.
Its updated outlook says electricity consumption from AI-focused data centres will triple between 2025 and 2030.
Data centre electricity demand grew by 17% in 2025, while electricity use at AI-focused data centres surged 50%.
