"His core defense: That massive, unexplained increase in hydropower capacity wasn’t a modeling error; it was a modeling assumption. He assumed that the U.S. could simply add turbines on existing dams such that they could deliver 15 times more instantaneous capacity, even though total flows for a year would remain constant" This seems like a pretty big error. Enough for me to be unsure of the paper linked here.
