Solar energy has surpassed coal as a source of U.S. electricity generation for the first time, with utility-scale solar accounting for 12.8% of the nation's power in May 2026, compared to coal's 12.2%. This rapid growth is attributed to advancements in large battery energy storage systems and decreasing costs for solar and battery installations. California, in particular, has seen solar generation overtake natural gas, with solar electricity generation increasing by 21% in the first five months of 2026 compared to the same period in 2024. Meanwhile, Elon Musk's SpaceX is exploring the concept of orbital data centers, powered by solar satellites, as a potential solution to the growing terrestrial data center demand and its associated issues.
