We should be able to survive a power outage. There is a stove on each floor that heats everything well. Wood and briquettes are available. Water supplies are of course also there – and in an emergency, we have a well with a hand pump plus water disinfection. Yes, go ahead and laugh at me, but I always keep my Weck jars >1l filled with water. Two backup generators including fuel reserves are also available. Cooking options as well. The only problem will be the mother-in-law who will show up here :D
...yesterday there was a fire at the Nürnberg power plant. Two districts are affected; the district heating was turned down to 10 to 15 degrees. The nights are expected to be cold. Fortunately, only the district heating is affected. But things can go faster than you think.
