Elon Musk said the United States needs substantially more electricity for artificial-intelligence infrastructure, particularly energy sources that do not depend on China, and estimated that AI could drive 20%-30% of global economic growth by significantly improving productivity. At a Sept. 1 G20 tech ministerial meeting in North Carolina, he contrasted US power-generation growth of roughly 4% to 7% annually with China’s addition of approximately 543 gigawatts in 2025, including about 315 GW from solar. Musk said xAI is deploying dozens of natural-gas turbines at its Colossus data centers because they can provide power within months, while transmission lines and nuclear plants generally take years. Gene Munster of Deepwater Management said power could become the next major AI infrastructure investment opportunity, comparing the theme with Nvidia’s 2023 breakout. Tesla and SpaceX are pursuing large-scale solar production, while xAI is also developing solar and battery projects.
