Frank Pallone is demanding emissions data and a site visit over the gas turbines powering xAI’s Colossus supercomputers, near mostly Black communities in Tennessee and Mississippi. The top Democrat on the House Energy and Commerce Committee is demanding that Elon Musk account for the pollution from xAI’s data centres, escalating a fight over the gas turbines that power the company’s supercomputers. Frank Pallone sent the letter on 29 July, seeking emissions data, permitting records, and access for committee staff to visit the sites. The facilities in question are xAI’s Colossus clusters. xAI installed 59 gas turbines for Colossus 2, Reuters has reported, without securing the federal clean-air permits that emissions of that scale normally require.
