How do you get to this range? That's quite a spread.
When I last ran the math, my daily usage (efficient and effective productivity, not spamming Gas Town) came to about 0.67 kg of CO2, which is roughly equivalent to my individual emissions from the 1 mile public bus ride home from work.
The difference is so big because renewables are just that much more efficient than coal and, to a lesser extent, natural gas. You can have 60% coming from renewable sources and still emit 400g/kWh with a coal and gas mix, whereas all hydro is 24g/kWh according to that source. The production component is what makes renewables not completely emission-free
I would imagine there's a huge spread there too. Depending on hardware, size of the model, requests being batched and queued rather than occupying a whole GPU or TPU, or if you are running an agent loop for 8 hours straight or spend most of the time reviewing results.
So what you're saying could sound as though pair programming with the machine is less CO2 for the environment than adding another human to pair program with.
This is how the AI ends up with "end humanity" cults.

Oh, you haven't met _that_ part of the climate people. A surprising number of them do want to reduce the number of people and they see "degrowth" as the solution.
What? That's not how it works at all?
Edit: dams release water when you need power or when they are full, not all the time
Sure, but they're not infinitely large. I realized that it would be more accurate to mention this and edited that into the sentence after the one you quoted (you probably saw only the earlier version -- fair enough!), but either way, the average power consumption needs to be above the average water flow for it to not be 'wasted' (when the electric dam is already there anyway) so that part is basically free energy which we might as well use
Like, when electricity prices are negative in my area, I'm charging my EV (albeit a tiny one) no matter if I'm planning to drive tomorrow because there is a surplus anyhow and there might not be one when I want to charge next. Even without dynamic pricing, it costs me the same 35ct/kWh but there's just no reason not to, that I know of, until demand exceeds supply again. Even if they never shut down the coal plants (even during the heart of summer) and some of my electrons will be from coal, afaik every additional Wh used will come from the renewables rather than (like at night when the renewables have a fixed maximum supply) from the coal/gas plants. We don't have enough hydro storage around here to store even a single night's supply
