TIL Dankelflaute, a time when it is too dark with too little wind for either solar or wind energy generation. Thank you for this amazing word.

It has to be scoped by area. A Dankelflaute that covers the European continent has never been observed. OTOH, a Dankelflaute that covers only Germany is a regular occurrence.

So, you're telling me there is daylight in Spain when we have night in Germany?

Also, have you ever done some research on how winds work? They're usually blowing (or not blowing) across the whole continent.

So, yeah, Dunkelflauten usually cover the whole continent.

I'm saying there is always wind blowing somewhere on the continent. For the time period where we have had widespread measurement of wind speeds continent wide, there has never been an hour without enough wind to turn a generator in some location.
