This turning point is decades in the making — not a policy target, but an economic reality arriving ahead of schedule. Wind and solar costs have dropped so sharply that 74% of the U.S. coal fleet could now be replaced by renewables while still saving customers money. April’s seasonal conditions give renewables a boost they don’t always enjoy, and annual parity remains years away. But the direction is no longer in doubt — and as utilities retire coal plants early, this milestone signals to energy markets worldwide that the crossover isn’t hypothetical anymore.
