some experts fear consequences that are difficult to measure

There is an initiative to build a gigantic data center in Utah (USA). The so-called Stratos Project plans to occupy an area equivalent to the city of Washington DC and is estimated to consume 9 GW of power. Some experts warn that the thermal impact will be devastatingand they claim that “it is the equivalent of releasing the energy of 23 atomic bombs a day in the form of heat.”

A Dantesque project. The approval of Project Stratos occurred at the beginning of May by the Box Elder County Commissionersthe community in northwest Utah on whose land it will be located. The megacomplex plans to occupy 16,100 hectares of surface, and if completed it will become the largest data center on the planet. That record is disturbing and alarming.

9 GW of computing capacity. This data center will consume 9 gigawatts of power, a figure that doubles the current electricity consumption of the entire state of Utah. The figure, like all those surrounding the project, is absolutely exaggerated, and there are many those who have criticized the project.

But also GW of heat. The biggest concern for experts It’s not just energy consumptionbut how this will affect the temperatures of the region in which this data center is intended to be built. Robert Davies, a physics professor at Arizona State University, has made the first calculations on this impact and his conclusions are worrying. Because the natural gas plants that will generate electricity for the center are 57% efficient, the complex will produce about 7 or 8 GW of waste heat. Once that electricity reaches the servers, it will be converted into heat, and it is estimated that Project Stratos will emit about 16 GW of thermal energy daily in the Hansel Valley where it will theoretically be located.

23 atomic bombs. Davies points out that this release of heat in a closed basin like the one in this valley is equivalent to “depositing the energy of 23 atomic bombs every day in the local environment.” It is obvious that the project does not generate nuclear explosions or radiation, but it will cause notable climate change. The models estimate that daytime temperatures will increase by 2.7 ºC on average, but the nighttime ones will suffer peaks of up to additional 15.5ºC. The semi-arid climate of the region, one of the driest in the US, will transform into an area with thermal dynamics similar to those of the Sahara Desert.

Threat to Great Salt Lake. The location chosen to locate this AI data center is not coincidental: the Hansel Valley is the area through which the so-called Ruby Pipeline passes, a gas pipeline that transports natural gas from Wyoming to the west coast of the United States. The problem is that it is also very close to the northern end of the Great Salt Lake, a body of water that has already been in danger for some time. In fact, its water levels are near historic lows after an unusually dry winter.

we were few. The supply contracts indicate an even greater risk to that body of water. The developers plan to acquire local water rights equivalent to about 16 million cubic meters. It is a volume sufficient to cover the basic needs of more than 20,000 homes in Utah.

Data center hate is real. This is the latest and most notable case of mega data center construction projects that trigger frontal rejection from local communities in the US. While AI companies and hyperscalers continue to announce new data center construction projects, residents of these areas organize local resistance.
