I just read that somewhere in rural Bavaria a small community has built itself a so-called "super battery". These are six above-ground larger buildings in small house format, with the capacity to supply 10,000 households with electricity for one (1) hour in the event of a dark period, when neither the sun is shining nor the wind is blowing.
Ten thousand households. One hour.
The day has
24 hours. Germany has
41 million households. And industry. And hospitals. Airports. Railroads. Etc. Etc. Etc.
And dark periods can last not just for an hour, but for several days. A week. Ten days. Occurs every winter on average, depending on the year, 1-3 times.
So, to supply 10,000 households not for one hour, but for ten days, we multiply these six battery houses by 240. Projected to 41 million households, we multiply again by 4100. So 6x240x4100. Then we are with over 5.9 million such battery houses, which would have to stand around in Germany. Additonally to the other buildings, and 75,000 windmill towers. The industrial and economic supply and infrastructure we ignore once, those come otherwise on top of the total count.
At the moment there are about 19.5 million residential buildings in Germany.
Germany.
In the 2023 World Competitive Ranking, Germany just has dropped from rank 15 to 22. I predict that is far from being the end of the downward journey. Add other problems like demographics, inadequate school education, desintegration of infrastructure systems...
