I thought this video was rather interesting, because at 12:27, the presenter crunches the numbers to find out how many years it would take for a new computer purchase to be more environmentally friendly (in regards to total CO2 expended) compared to using a less efficient used model.
Depending on the specific use case, it could take as little as 3 years to breakeven in terms of CO2 if both systems were at max power draw forever, and as long as 30 if the systems are mostly at idle.
Kodi is a graphical app, like Firefox, so you won’t use docker for it.
It’s the other half of the home server that’s giving me docker trouble, the *arr stack; I hadn’t actually gotten to the stage of trying to set Kodi up yet
What problem are you having? Docker is very straightforward, just copy the compose file and run a command.
