Who paid, from the report's own pages: the work was done by Lawrence Berkeley National Laboratory with support from the Department of Energy's Industrial Technologies Office, and the lab is operated for the DOE by the University of California under contract DE-AC02-05CH11231. Two details matter more than the funding line. The input data was provided by three commercial research firms, Omdia Research, S&P Global and the International Data Corporation, so the raw numbers come from private datasets rather than public ones. And the acknowledgements thank experts from organizations representing major data center equipment manufacturers and data center owners who answered questions and commented on the assumptions used in the analysis, so industry helped shape the modeling inputs even though it did not pay for the report. This is still the closest thing to a neutral scorekeeper and the safest number to quote on either side, because the funder has no stake in the answer and the method is published. Know the two caveats anyway. One caution on the numbers: the 2030 estimate is a range, 578 to 782 TWh on the report's single-factor sensitivities and 521 to 843 TWh on its wider compounded uncertainty range, and the authors give a range precisely because a single confident number would not be honest. Do not quote the middle figure as a prediction.
