Which energy management practice helps improve efficiency and reduce operating costs?

• A. Expanding outdoor lighting
• B. Increasing standby equipment
• C. Ignoring energy use
• D. Metering and submetering

Answer: (D)

Measuring energy use and understanding where it flows is the foundation of efficient energy management. Metering provides a read on total consumption, while submetering breaks that down into specific areas, systems, or pieces of equipment. With that detailed visibility, you can spot waste, establish baselines, and track the impact of efficiency projects over time. This enables informed decisions, tighter control, and the ability to verify that savings are actually achieved, which translates into lower operating costs. The other options would tend to increase or ignore energy consumption rather than reduce it; expanding outdoor lighting adds load, increasing standby power adds idle consumption, and ignoring energy use eliminates the feedback needed to optimize operations. In short, data-driven monitoring through metering and submetering is what makes targeted energy upgrades effective and cost reductions possible.
