Elon Musk Outlines SpaceX Vision for Terawatt-Scale Solar Power on Earth and Moon

Elon Musk has outlined an ambitious long-term vision for SpaceX involving the development of solar energy capacity on an unprecedented scale, including a target of one terawatt per year on Earth and more than one petawatt annually from the Moon.
A petawatt is equivalent to 1,000 terawatts, making the proposed lunar target vastly larger than existing terrestrial solar installations. Musk suggested that achieving such an extraordinary level of energy production could make SpaceX more valuable than Earth itself, a speculative statement rather than a conventional financial valuation.
The concept reflects Musk's interest in combining space infrastructure, large-scale manufacturing and energy generation. However, producing and deploying solar systems at the proposed scale would require technological, logistical and financial capabilities far beyond those currently demonstrated.
No confirmed construction schedule, investment budget or commercial implementation plan accompanied the remarks. The targets should therefore be understood as an aspirational vision rather than established production forecasts.
