power supply
The provision of electrical energy for devices, buildings, or an entire area.
Wegen des Sturms wurde die Stromversorgung für mehrere Stunden unterbrochen.
Because of the storm, the power supply was interrupted for several hours.
The word is made up of 'der Strom' (electric current/power) and 'die Versorgung' (supply/provision). So it literally describes the supply of electrical power.
Eine stabile Stromversorgung ist für die Industrie unerlässlich.
A stable power supply is essential for industry.
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).
Nach dem Gewitter war die Stromversorgung für mehrere Stunden unterbrochen.
After the thunderstorm, the power supply was interrupted for several hours.
You can tell from context whether the power supply unit of a device is meant. In this case, 'Stromversorgung' (power supply) is treated like a countable object that you can 'kaufen' (buy) or 'austauschen' (replace), or that can be 'defekt' (defective).
Mein Computer startet nicht mehr; ich glaube, die Stromversorgung ist defekt.
My computer won't start anymore; I think the power supply is defective.
energy supply
'Stromversorgung' and 'Energieversorgung' both describe people, buildings, or devices being supplied with energy. However, 'Stromversorgung' refers only to electrical energy. 'Energieversorgung' is broader and can also include gas, heat, or other forms of energy. The words can be confused because electricity is an important part of the energy supply. If you are talking specifically about electricity, sockets, or devices, 'Stromversorgung' is more precise. If you are talking about the whole system of electricity, gas, and heat, 'Energieversorgung' fits better.
Nach dem Sturm war die Stromversorgung im Dorf mehrere Stunden unterbrochen.
After the storm, the power supply in the village was interrupted for several hours.

In winter, the city talks a lot about a secure energy supply.
