Someone needs to do a good xkcd like visual of the relative energy and carbon footprint of things. You can really see a surge of honest yet weird questions like this from people because there has just really been no good accounting and communication to give people a frame of reference.

Personally this is the one I visualize and use as a mental rubric when people ask about individual behavior options: https://i2.wp.com/shrinkthatfootprint.com/wp-content/uploads... but its a decade old and "average american" centered.

I think it would really help both better decision making and better conversations if people understood that there is no one answer to any of these questions. You just have to rank things by footprint and start at your top. If you're doing things that are #7 on your own footprints list instead of things that are #1 - #3 then you're not being an engineer, you're fretting.
