I'm saving infinite money by never going to the bar at all! I'm wealthy beyond dreams!
In reality, one 5W bump isn't going to move the needle, but you only have to make that concession a few times before you end up adding an appreciable amount to your power bill. I'm paying €0.39/kWh for power. When I added Starlink (57-75W constant draw, equating to at least €12/mo on the bill) I went looking for things to unplug to wash that increase out. Turns out my power consumption monitoring plugs were using about 15W on their own, and having too many wireless access points was adding another 45W. That's all been sorted out, and I'm more cautious of suffering death by a thousand cuts now.
