How to lower the cost of running a desktop computer

Everyday desktop use — browsing, documents, video calls — is light work for a modern PC, so most office desktops plus a monitor draw around 100–200W. Workstations rendering video or running heavy software use more. Sleep mode drops consumption to just a few watts, so letting the computer sleep when you step away makes a real difference over a year.

  • Set the computer to sleep after 15–30 minutes and the display after 5–10 minutes.
  • Turn off the whole setup with a power strip at the end of the day.
  • Lower monitor brightness — it often accounts for a big share of the total.
