## Quote — verbatim

> The US Department of Energy report estimates US data centers consumed about 176 terawatt hours in 2023 — about 4.4% of US electricity. By 2028, the range is 325 to 580 terawatt hours, or 6.7% to 12% of US electricity. At the high end, that's 1 in 8 watts on the grid going to data centers... Analysts are warning by 2026, 40% of AI data centers could be stuck waiting for power, even as some facilities spin up diesel at peak to stay online.

The quantified energy case; he adds global data center electricity "could approach about 945 terawatt hours by 2030."
