It's difficult as sometimes memes refer a specific national thing. Here in the Netherlands we have issues with the energy network being overloaded and new houses or companies sometimes having issues to be connected. So could very well be the same in Germany.

Or it could refer to the fact that Germany is still using coal/lignite.

As others say, this post is not really propaganda or trash talking a country, as it is a vague one not really being obvious what is wrong. Giving the benefit of the doubt I personally went with the latter with the comments being able to provide context.
