The environmental comparison I'd be interested in seeing is between a year of heavy personal usage of LLMs (ChatGPT, Claude, Gemini etc) compared to the CO2 emissions from a single passenger flight

Can I do my own personal carbon offsetting by skipping one trip a year?

Does that question even make sense?

@simon Knowing the location of datacenters and using a source like https://app.electricitymaps.com/map you can guestimate the carbon footprint. My employer did the same for its datacenters in Norway but its somewhat complicated by a complex energy exchange market (we're connected to UK, Germany, Netherlands, Denmark, Sweden).
