Which of the following actions can help reduce energy consumption in a workcenter?

Turning off computer monitors at night is an effective way to reduce energy consumption in a workcenter. Monitors can consume a significant amount of electricity, especially if they are left on for extended periods when not in use. By powering them down during non-working hours, the workcenter minimizes unnecessary energy use, contributing to overall efficiency and lowering operational costs.

In contrast, using more artificial lighting increases energy consumption rather than reducing it. Keeping computers running at all times contributes to energy waste, as they consume power even when not actively in use. Increasing air conditioning usage typically leads to higher energy bills and resource consumption, which runs counter to the goal of reducing energy usage. Thus, the most efficient action is to turn off monitors during periods of inactivity to enhance energy conservation.
