What EIA projected, and what actually happened
Every Annual Energy Outlook since 2015 has projected U.S. electricity demand and the fuel mix a quarter-century ahead, and utilities, RTOs and federal rule-writers plan against it. Laying each edition's Reference case over what the grid actually did shows where the model and the market parted: flat demand that stopped being flat, a coal fleet that retired three times faster than projected, and solar that arrived a decade early. Projections are AEO Tables 8, 9 and 16; actuals are the Monthly Energy Review, the Electric Power Annual and the Short-Term Energy Outlook, with 2025 still preliminary. EIA published no AEO2024.
