I honestly find this obsession with LLM energy usage weird. The paper listed gives typical energy usage per query at around 1Wh for most models at a reasonable output length (1000 tokens). A typical home in the UK directly uses around 7,400 Wh of electricity and 31,000 Wh of gas per day.
I just don't see why some people are obsessing over something which uses 0.01% of someone's daily electricity usage as opposed to far more impactful things like decarbonising electricity generation, transport and heating.
