Elon Musk's xAI is under fire for illegally using dozens of methane gas turbines to power the Colossus data centres in Tennessee.

In June of 2025, xAI's Colossus data centre outside of Memphis faced a lawsuit for operating at least 35 natural gas turbines but failing to secure a permit for 20 of them, per a Tech Crunch report.
