I would like to ban moving screen savers (photos and graphics) in my office - from what I understand, they use at least as much energy if not more than when a computer is in use/processing. And when a screen saver is on or the photos are moving, the employee is not generally around to look at it anyway. If an employee is away at lunch or at a long meeting, these screen "savers" are on for hours.
However, my employees have personal photos of friends and family on these computers, or have something meaningful/pretty to look at in general. Is it fair to ask them to take down these screen savers? I personally do not have such items on my monitor because of personal preference (although I have a few photos in frames on my desk). Is the energy waste worth employee morale? I am thinking it is not.
