Elon Musk, the visionary tech entrepreneur, has once again championed the potential of solar energy, citing the Kardashev Scale and simple math to support his claims. He argues that a small portion of Texas or New Mexico could easily power the entire United States with solar energy. Musk also highlights the immense potential of solar power, given the amount of energy the Earth receives from the sun, and emphasizes the efficiency of his own Starlink satellite network, which runs entirely on solar and battery power.
