Multiple choice

Which of the following is NOT a key component of an energy management system (EMS) in an industrial facility?

  1. Energy monitoring and measurement

  2. Energy efficiency assessment

  3. Energy procurement and contracting

  4. Energy policy and objectives
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Energy procurement and contracting is not a key component of an EMS. It is related to the process of acquiring energy from external suppliers, while an EMS focuses on managing energy consumption within the facility.
