In Frankfurt, Germany, the grid is currently so saturated that no new connections will be available until at least the 2030s. There, data centers consume about 41% of the city's electricity. In Dublin, it's double that.
And data center electricity consumption is growing rapidly — it's expected to double by 2030 to about 945 terawatt-hours, around what Japan consumes annually, according to the International Energy Agency.
