[Viewpoint] Energy security as a crucial component of health infrastructure: global evidence and actions

Energy security, defined as the availability of reliable, clean, and sustainable energy necessary to ensure the continuous operation of health-care facilities, is essential for delivering safe and effective health care.

Evidence from nearly a thousand hospitals shows that power outages were common, especially in lower-income settings, disrupting surgery, diagnostics, cold chains, and digital records, with reports of direct patient harm and environmental costs.
