Here's Deutsche Welle - what used to be the German international radio service - on the subject:

German authorities believe a militant climate activist was behind a series of recent sabotage attacks on the country's power grid and are hunting for a 48-year-old suspect.

This suspect is now under arrest as also can be read in the following report by The Local (DE):

* German police on Tuesday arrested a suspected militant climate activist over a spate of sabotage attacks on the power grid that had apparently aimed to disrupt power from coal-fired plants.

The man, partially named in German media as Daniel V., 48, had spent days on the run since the first attacks last Tuesday in Brandenburg and North Rhine-Westphalia (NRW) states.

Police in the city of Cologne said Tuesday that officers had "apprehended the wanted 48-year-old suspect near the Weisweiler power plant" in NRW state.

"The man was carrying additional explosive devices at the time of his arrest but offered no resistance," they said in a statement.*

Now that I showed these sources - none of them exactly 'Russian-friendly' as you might know, otherwise read a bit more of their reporting on similar subjects - will you agree that this specific case was not directly related to Russia? That these 'climate extremists' do not need to be directed by the FSB or GRU to attack their own country's infrastructure because they have somehow convinced themselves that their 'climate activism' is a good cause?

After you agreed to this can you also agree to the fact that blindly claiming 'Russia Russia Russia' does nobody a favour, least of all those who want to be able to show where Russia is actually responsible for similar attacks? This is quite important because in the end it is not infeasible that Russia and its Soviet Union predecessor are actually responsible for these anti-Western activities through the decades of support - financial, ideological and sometimes practical - they lent to all manners of activism in the west with the goal of undermining western society.
