ISO 50001 is a standard intended to improve energy use through a(n) ___.

• A. Lighting control system
• B. Energy management system
• C. MCC
• D. Communication system

Answer: (C)

ISO 50001 centers on creating, implementing, and continually improving an energy management system (EnMS) within an organization. It provides a structured framework—often described through a Plan-Do-Check-Act cycle—for systematically managing energy use, performance, and efficiency. Key pieces include setting an energy policy, establishing baselines and energy performance indicators, conducting energy reviews, setting objectives and targets, and regularly auditing and reviewing progress with top management. This holistic approach helps organizations reduce energy consumption and costs over time, not just by upgrading a single device, but by integrating disciplined energy management into everyday operations.

The other options describe specific technologies or components (like a lighting system, a motor-control center, or a general communications system). While those can contribute to energy savings, ISO 50001 is about the management system that governs energy use across the organization, not a particular piece of equipment.
