When referring to the provision of energy for an area, the word is often used with verbs such as 'unterbrechen' (to interrupt), 'wiederherstellen' (to restore), or 'zusammenbrechen' (to collapse). Common adjectives are 'stabil' (stable) or 'zuverlässig' (reliable).

Stromversorgung can generally refer to supplying a device with electricity, but it can also refer to the device used for this purpose. Netzteil always means the specific component that converts and passes on the electricity in the appropriate form. Use Stromversorgung when the function is the focus, and Netzteil when you mean the device.
