Still an absurdly high number. fixed line internet has 0.06 kWh/GB according to this 2018 study:

The majority of data heavy stuff also tends to happen in WiFi environments. So I dont know where this 300x overhead increase is supposed to come from. A typical 3G base station is burning 500W/h no matter what data usage is. So unless you share you wireless cell with less than 5 people this should be magnitudes below a fridge. The wired part of the infrastructure is much more efficient and aggregated in general.

I suppose the biggest culprut are not even the smarthones, but their cloud storage services, which are completely optional and not used to a large extent by the majority of smartphone users.

Most of all ISP profits and subscription costs would also be decisively lower/higher if energy use and therefore cost was supposedly that significant.

> 500W/h

Again, "W/h" is almost always wrong. You mean just "W", which already contains the "per time" part because W = J/s.
