The Stratos artificial intelligence datacenter footprint will cover more than 40,000 acres (62 sq miles) over three sites in Box Elder county in north-western Utah. The facility will require about 9GW of power, which is more than the entire state of Utah currently consumes, and suck up a significant amount of water in an area that has been hit by severe drought in recent years.
Assuming that happens, I think we can look to Detroit, starting 50 years ago, for a good example of how awful we are at scaling down and retiring infrastructure at anything approaching this scale. Especially when the state doesn’t care to require companies to clean up their mess.
