The biggest solar story isn’t that it passed coal and wind. It’s what happens next

In May, solar generated more electricity than either coal or wind across the United States for the first time in a single month. New figures from the U.S. Energy Information Administration show solar produced 47,147 gigawatt-hours, ahead of coal’s 45,119. Over the first five months of 2026, utility-scale solar output rose 21.6 percent from a year earlier, while coal generation dropped 10.9 percent. The agency projects that solar, wind, and battery storage will add about 83 gigawatts of new capacity by May 2027. Fossil and nuclear capacity are set to slip by nearly 4.7 gigawatts over the same period. Strip away the energy specifics and this is a story about how disruption actually arrives. Disruption often looks like a sudden and surprising event where one product or technology overtakes another. But in solar, as in many other industries, it’s actually the logical trajectory of a cost curve that has been bending for more than a decade. The question for any leader watching a slow-moving trend in their own industry is simple: How do you tell a curve that will lead to disruption from one that never will? The solar crossover was never the surprise Each time the world’s installed solar …
