>>Because of unfortunate timing of when my contract expired I already pay around 800 euros per month for energy
Wait, what? Are you like cryptomining or something? That's actually insane. I charge two electric cars at home, work from home using a powerful workstation, and my electricity is about £100/month. How do you manage to spend 800 euro a month????
Curious where you are? I run a threadripper workstation with a 3070Ti and 2x 1440p monitors for ~10 hours per day, and my household's electricity bill is ~£40/month.
