Hubris is one of the great renewable resources.

O’Rourke’s line is a sardonic twist on the language of energy policy and environmentalism. By calling hubris a “renewable resource,” he suggests that human overconfidence—especially among leaders, experts, and ideologues—never runs out: it regenerates as quickly as it is discredited. The joke carries a moral edge. Hubris is treated like a dependable supply, but it is also a dangerous one, because it fuels reckless decisions and repeated historical mistakes. The aphorism implies a cyclical pattern: failures rarely cure arrogance for long, and each generation finds fresh reasons to believe it is exempt from the limits that humbled its predecessors.
