After buying energy monitor "smart plugs" last week, I've learned a few things—
My PC uses WAY more energy than the fridge. I have a bad habit of leaving my PC on overnight. Even "asleep" my PC is using 3x more energy than my fridge.
For games I play #overwatch (FPS) and #osu (rhythm game). My PC uses far less power running Osu! (200 watts) vs Overwatch (500 watts). Osu! is noteworthy because it has native Linux builds, which may explain why my PC uses LESS power than normal when running Osu!
