Question

Options

• APut monitors off at night.
• BTurn down the brightness of the display.
• CUse one power strip for all your chargers.

• A
  81% (25)
• B
  13% (4)
• C
  6% (2)

Explanation

Powering monitors off entirely at night eliminates their energy draw completely during the many hours a workplace is unoccupied, making it the highest-impact habit - monitors can consume 20–100W, and eliminating that for 8+ hours nightly adds up significantly across an organization.

Why the distractors fall short:

• B (reduce brightness): Dimming a screen only cuts power by a small percentage (often 10–30%) and still leaves the monitor drawing power 24/7 - a minor reduction, not elimination.
• C (one power strip for chargers): Consolidating chargers onto a single strip offers no inherent power savings on its own; it's a convenience measure. It could help if used as a switched strip to kill standby draw, but that's not what the choice states.

Memory tip: Think "off > dim > consolidate" - complete shutdown always beats partial reduction. When in doubt on Green IT questions, the option that removes consumption beats the one that merely reduces it.
