level: business
elon musk's xai is powering its ai data centers with dozens of unregulated natural gas turbines and plans to buy $2.8 billion more, moving away from the solar electric economy he once championed. this contradicts tesla's master plans, which aimed to eliminate fossil fuels. xai has spent $697 million on tesla megapacks for peak load management but has not bought significant solar panels from tesla.
spacex's ipo filing emphasizes space-based solar power, claiming it can generate over five times the energy of terrestrial solar due to constant sunlight. musk and other silicon valley executives see orbiting data centers as a solution to earthbound opposition and power constraints. however, the economics are challenging, with high launch costs and the difficulty of protecting chips in space. it is also unclear if ai training can be distributed across satellites.
musk believes ai compute demand will grow at terawatt-scale annually, far beyond current data center capacity. he views xai's gas-powered centers as temporary until space-based servers are viable. but critics note that earth's solar potential is barely tapped, and shipping panels by truck is far more efficient than launching them into orbit. the shift raises questions about musk's commitment to terrestrial clean energy.
why it matters: this highlights the tension between ai's growing energy demands and clean energy goals, showing how tech leaders may prioritize rapid scaling over sustainability.
