Colossus is housed in a predominantly Black, south Memphis community which heightens residents' risk to severe health issues

xAI has come under scrutiny in recent months for operating methane gas turbines at its Memphis facility to meet the electricity needs of the supercomputer Colossus. The turbines emit pollutants, including nitrogen oxides and formaldehyde, according to their manufacturer.

NAACP accuses Elon Musk’s xAI facility of environmental violations and requests officials in South Memphis shut down the data center, which runs the Colossus supercomputer.
