- Electricity and water usage of AI chatbots in 2025 was better estimated, with individual usage being a rounding error compared to other daily activities.
- Median queries consume around 0.3 Wh, but coding agents like Claude Code use orders of magnitude more energy due to longer sessions and tool calls.
- A typical Claude Code session consumes ~41 Wh, and daily usage can reach ~1,300 Wh, comparable to running a dishwasher or skipping a short drive.
- Energy estimates are based on napkin math and assumptions due to lack of comprehensive data from frontier labs.
- The environmental impact depends on the energy source; renewables make the impact less concerning than fossil fuels.
- Advocating for green energy transition is more effective than reducing individual LLM usage for climate impact.
- The author donates to organizations promoting green energy in tech, despite not reducing personal usage of coding agents.
