Elon Musk Says ‘Enormous, Free Fusion Reactor in the Sky’ Will Supply 100% of Energy Needs
Tesla's energy revenue rose 13% YoY to $3.1B in Q2 2026, with capex up 141% to $5.8B. CEO Elon Musk predicts solar will supply 100% of global energy, backing this with $25B annual capex and $30B debt. The EIA disagrees, estimating solar will reach 20% by 2050. Tesla targets Megapack 3 production in Texas this year.
