Elon Musk has frequently championed solar energy as an essential pillar of a sustainable global power grid, famously noting that humanity sits underneath a giant nuclear fusion reactor in the sky. He has emphasized that transitioning the world to a fully sustainable energy ecosystem requires a combination of solar and wind generation paired with massive stationary battery storage to handle nighttime and low-generation periods. Musk has consistently argued that if a tiny fraction of land area were covered with photovoltaic panels, it could easily power the entire United States or the globe, highlighting that scaling manufacturing capacity for both solar collection and battery storage remains the ultimate key to unlocking a zero-carbon energy future.
