- 2025-04: Why using ChatGPT is not bad for the environment - a cheat sheet
- A single LLM response uses only ~3 Wh = 11 kJ (~10 Google searches; examples of 3 Wh energy usage)
- Reading an LLM-generated response (computer running for a few minutes) typically uses more energy than the LLM generation of the text.

Examples
- LLM query
- 3 kW * 4s = 3 Wh = 11 kJ
- Human brain
- 20 W * 8h = 106 Wh
- 20 W * 1h = 20 Wh
- 20 W * 10m = 3 Wh = 10 kJ
- Human brain excess thinking
- 2 W * 8h = 11 Wh
- 2 W * 1.7h = 3 Wh
- Regular computer
- 200 W * 8h = 1,600 Wh = 5,700 kJ
- 200 W * 1m = 3 Wh = 10kJ
