The linked page includes the energy cost of a Google search. I made an informed guess that operations done infrequently and deliberately written in extremely power-inefficient ways cost at least that much.
And what did you base that off of? Do you know the efficiency of a Stripe transaction, compared to a Google search? And what does "a Google search" even entail? How far down does it go? Where did that number come from?
How could you possibly compare the two?
At best, you're making a guess (I wouldn't exactly call it "informed") based on some randomly sourced data on a blog, which uses another blog for its source, which uses a third blog.
