Thank you, that sheds some light onto it, yes. I'm still wondering how this number marches up. Just using the device by far uses not even comparable amount of energy than e.g. the production and then it also depends if you use green energy or a diesel generator in your backyard.
I use https://miniflux.app/ now after switching from tinytinyRSS, which was in fact, not so tiny 😉
Miniflux has a simple, minimal web UI which works nicely from any device. It is kept simple and minimal, which I consider nice but might not be everyone's cup of tea.
In short: this is small, nice, easy to use and it runs on minimal resources. I'm happily using it for years already. 👍
Aye Aye Dolphin!
