0.04 to 0.1 kWh/GB is insane even for 2018 lol.
I have gigabit internet (125 MB/s). This would imply when I'm downloading something I'm using 18 to 45 kW of electricity. Completely bonkers.
I'd guess there is some offset power needed for keeping a "line" open. Like, 200 kB/s is not twice the power of 100?
Clearly you're charging an EV to drive a jar of microsd cards with your data back and forth
It would also imply that it costs Google ~7¢ in only energy cost to deliver that file to you (using average EU energy costs), which is clearly non-sensical given the rates hyperscalers charge for network egress.
Additionally, the cited number also conflates wired internet (low power consumption) with mobile internet (higher), even though this model is only being downloaded to Chrome Desktop AFAICT.
