xAI's gas-powered data centers in Mississippi spark environmental concerns as tech companies increase fossil fuel reliance for AI

Elon Musk's xAI is constructing massive data centers, named "Colossus 1" and "Colossus 2," with a third "Macrohardrr" planned, near Southaven, Mississippi, to power his "anti-woke" chatbot Grok. These facilities are powered by dozens of methane gas turbines, generating enough electricity for hundreds of thousands of homes and emitting formaldehyde and nitrogen oxides, leading to "unpermitted power plant" concerns and "fierce community opposition." The Southern Environmental Law Center (SELC) has filed a lawsuit against xAI over clean air violations, which the Trump administration has attempted to dismiss, citing "paramount national security" for Grok.

This development by xAI highlights a broader industry shift where major tech companies, including Google, Microsoft, OpenAI, and Anthropic, are abandoning their previous climate idealism and decarbonization pledges due to the immense energy demands of the AI arms race. OpenAI is planning a massive data center in Ohio powered by the largest natural gas plant in the U.S., which the Ohio Environmental Council warns will have "astronomical" climate and public health impacts.

Critics, like scientist John Fleming from the Center for Biological Diversity, argue that feeding data centers with fossil fuels "is taking the climate crisis we have now and blowing it up like the Incredible Hulk." The article suggests a "Fossil Tech" symbiosis between Big Tech and the fossil-fuel sector, with organizations funded by petroleum billionaires lobbying for AI deregulation. Even as these companies acknowledge the increased emissions, they contend that AI will ultimately "fix" the climate crisis it exacerbates.
