I don't really get the comparison.
With 10% of battery I can code for 3 hours. If I compare the result of this activity with the 10% of battery wasted on a single question whose answer probably won't be completely correct, I consider the latter to be excessive, in relative terms, even if I take into account my time cost. Theoretically, if I would need to ask 100 questions to complete one task, I would need to recharge my computer 10 times. This is why I offload the burden of energy usage to a third party such as OpenAI.
BTW I don't drive if I don't have to either, which might make me more sensitive than you to this, comparatively low, energy usage diff.
