Using three different methods I find that the typical agentic prompt uses 180 watt-hours (45 to 360 Wh). This adds up to around 3 kWh per day, around the energy of running two fridges.

For my understanding, where you talk about the reality being 150 to 1200 times higher, does that higher estimate include the energy used in model training? I don't think that's the point you're making but I'm just not clear! 🙏🏽

It makes sense to me that it is vastly higher than simple questions to a chatbot.

I also didn't realize the extent of efficiency improvements over the past decade. It's incredible. I'm glad you mentioned Jevon's paradox because it's definitely happening.

So efficiency is good, but it won't save us. Clean energy sources will help. It would be great if we (in the US) could tax or ban new fossil fuel energy sources.

Our annual use is 31kWh! 😯

Gas and other short term fixes for the capacity and distribution shortages should have a fairly short shelf life.

My M5 64GB laptop goes from a few watts to 50W or so (it has a 96W power supply) and the fans come on when it’s thinking hard. Thats still much less than sending prompts away to run on Claude.

I caught a typo in the "Credible estimates" link at the top of the article. Here is the URL from the article link:
https://eta-publications.lbl.gov/publications/2024-lbnl-data-center-energy-usage-report)

It works if I take off the trailing ")".

If AI's capital and urgency fund firm clean power and grids, it could help clean the grid. Behind-the-meter gas, and it won't.
