What's the environmental cost?

6 min read · energy, water, and keeping it in proportion

Fair question — and one that deserves an honest answer, not "it's nothing" and not "you're killing the planet by saying thanks to a chatbot." The truth sits in the middle, and it's worth actually understanding.

💧 One query is genuinely tiny

A single question to a chatbot uses a small amount of energy — very roughly ten times a web search, which is itself a small amount — and a fraction of a millilitre of water for cooling. On its own, one query lands somewhere between sending a few emails and boiling a thimble of water. (Estimates vary a lot and the research is young, so treat any precise figure with a pinch of salt.)

📈 …but scale and training are the real story

Where it adds up is volume and training. Billions of queries a day, plus the enormous one-off cost of training the models in the first place, plus a global building boom in data centres. That's where the real footprint lives — not in your individual chat. Framing it as "my one question" quietly misses the actual issue.

Your single query is a thimble. The honest concern isn't you saying thanks — it's a billion queries a day and the data centres behind them.

⚖️ Keeping it in proportion

Worth holding two things at once: it's not nothing, and it's also not the thing most worth losing sleep over in your day. A short drive, a load of washing, a single steak — each dwarfs a whole day of chatting to an AI. If you want to be a thoughtful user, the bigger levers in your life are almost certainly elsewhere. But "it has a cost" is true, and worth not pretending away.

🌱 What you can actually do

No hand-wringing required. Don't generate slop for the sake of it — fewer pointless regenerations, less "make me fifty versions of this." Use it for things that genuinely save you something real. And remember the providers move the big numbers, not you — greener data centres, more efficient models — so it's fair to expect that of them, and to lean toward the ones who take it seriously.
