Dr. Rob Davies, a physics professor at Utah State
University, prepared the analysis that estimates
the energy footprint of the proposed data center
is comparable to 40,000 Walmart Supercenters.
Size = 62mi² https://kutv.com/news/local/proposed-box-elder-data-center-r...
Energy usage = 9 Gigawats (Utah uses 4 Gigawatts total) https://www.cachevalleydaily.com/news/hundreds-of-utahns-fil...
Water usage permitted = 13,000 acre-feet (26k-39k homes worth) https://www.fox13now.com/news/local-news/box-elder-county/mo...
What is the standard "atomic bomb" unit these days?
This is an absolutely meaningless statistic. It's pretty hard to believe that it would be included in an otherwise informative article.
23 atomic bombs per day does not really tell me much. Both boxer's punch and a 9mm bullet have about 450 J of energy, but the effects are very different.
A better comparison would be ~550000 average US houses... or a single medium-sized aluminum smelter factory.
