Increase the power saving settings on all computers

Why

When you aren’t actually using your computer, it might still be using your electricity.  Save 190 kg CO2/year per computer by having your sleep settings activated.  How many computers do you think are in your company?  In your city?  Think how much electricity and CO2 emissions could be saved simply by having our computers go to sleep when we aren’t using them.  

How

Set your computer to fall asleep after 5-15 minutes of inactivity.

Note that “sleep” and “hibernate” each drop power use to about 1-3W.   Sleep wakes in seconds, but you may lose open work if power is lost.  Hibernate wakes in 20+ seconds, but saves your work even if power is lost.  You can chose “hybrid sleep” which wakes in seconds AND saves your work.  This one minute video shows how to quickly set up hybrid sleep in Advanced Power Settings.
