Which energy efficiency rating do HP Z displays have?

Question

Options

• AEPEAT
• BHERS
• CCommon Criteria
• DEnergy Star

• A
  4% (1)
• C
  8% (2)
• D
  88% (22)

Explanation

HP Z displays carry the Energy Star certification, which is the industry-standard energy efficiency program created by the U.S. EPA and Department of Energy specifically for electronic equipment and appliances.

Why the distractors are wrong:

• EPEAT (A) is a sustainability/environmental rating for electronics (covering recyclability, hazardous materials, etc.) - not strictly an energy efficiency rating, though related.
• HERS (B) is the Home Energy Rating System, used to score the energy efficiency of residential buildings, not monitors or electronics.
• Common Criteria (C) is a cybersecurity certification framework for evaluating the security of IT products - unrelated to energy efficiency.

Memory tip: Think "Energy Star = Energy efficiency for electronics." The name itself is the hint - it's the only option here that literally contains the word "Energy" and is the universally recognized label you see stamped on monitors, appliances, and computers in stores.
