GoKawiilStudy estimates Claude Code AI agent uses up to 5.9 kWh per day of coding tasks
Climate scientist Zeke Hausfather analyzed his own usage of Anthropic's Claude Code assistant and calculated that a typical day of work consumed between 1.2 and 5.9 kilowatt-hours of electricity, comparable to running two refrigerators nonstop for a day. He found that 96 percent of the roughly 3.2 billion tokens processed over eight weeks came from the agent repeatedly re-reading its own accumulated memory at each step, rather than generating visible output.
