Which of the following is a necessary component of power management?

Regular maintenance of power sources is crucial for power management because it ensures that all electrical systems operate efficiently and safely. This maintenance can involve checking for wear and tear, replacing outdated components, and ensuring that all connections are secure. By keeping power sources in good condition, businesses can prevent electrical failures that might lead to downtime or safety hazards. Additionally, regular maintenance helps in optimizing energy consumption and prolonging the lifespan of electrical equipment, contributing to overall cost savings for the business.

Frequent repositioning of displays and utilizing daylight for illumination can be part of a retail strategy to enhance customer experience or save on lighting costs, but they do not directly relate to power management. Removing all electrical components is impractical and counterproductive for any retail operation, as it would hinder essential activities that require power. Thus, maintaining power sources aligns with the framework necessary for effective power management within a retail environment.
