Reducing Electrical energy consumption in hospitals: A conceptual Framework for Reducing Idle Energy consumption of Medical Devices
Year: 2026
Type: preprint
Abstract: Electrical energy consumption in hospitals continues to rise, and a significant portion of this consumption comes from medical devices that remain connected to electricity even when they are not actively used. Some devices must remain powered at all times for safety or cooling requirements, while others consume electricity unnecessarily due to inefficient standby modes or outdated power‑management practices. This article presents a simple conceptual framework to classify medical devices into two categories based on their electrical behavior and proposes a basic mathematical model to illustrate how reducing idle connected time can decrease overall energy consumption. Although the model does not rely on precise numerical data, it demonstrates the clear relationship between unnecessary standby time and wasted electrical energy. The goal of this work is to highlight an overlooked source of energy waste in healthcare settings and to encourage the development of smarter, more efficient power‑management strategies for medical devices.
