I don’t think that’s your PC. I actually measured how much power my PC and my monitors consumed in a week and used that to calculate how much that would be for the year and compared to the total used energy for that year. My PC setup was only a small fraction of the yearly usage. The vast majority of your energy is gonna be consumed by things like fridges, ovens, heating, water pumps, etc.
I did the power measurement using a power meter. We also use natural gas for heating and don’t have any AC.
