Construction costs are currently skyrocketing

China currently has 1.4 billion people, which is 17 times as many inhabitants as Germany with 82 million. China has a nominal capacity of 1020 gigawatts in renewable energies, Germany 131. Put this into relation and you get the following values: China = 1.4 GW nominal capacity per 1 million inhabitants. Germany = 0.6 GW nominal capacity per 1 million inhabitants

But there is a calculation error - isn't there? I would calculate China: 1020 / 1400 = 0.72 GW/million inhabitants Germany: 131 / 82 = 1.59 GW/million inhabitants Nevertheless, I agree with your basic statement that China has generally recognized the energy dilemma and tries to act, simply out of self-interest.

Yes, he divided 82 / 132 instead of the other way around.

The Frankfurter Allgemeine currently has a longer article with forecasts on construction price development and the various supply chain problems on the homepage. Title: Hard landing for the construction industry. The decline in owner-occupied housing construction is estimated at 18%! The building material prices should ease for most sectors around the beginning of next year, but the overall construction costs will remain high.

To be honest, I assumed that people here understand the basic rule of three and at least have a small feel for numbers...

Apparently not. :D
Jokes aside. A large part of Chinese "renewable energy" comes from hydropower (almost twice as much as wind & solar combined).
It requires certain geographical conditions and cannot be scaled arbitrarily.

After my last construction weekend including a visit to the hardware store and tile dealer, the following can be stated: OSB panels are gradually becoming "cheaper" (still extortionate from my perspective but at least). The tile dealer currently has everything I need in sufficient quantity in stock and also at reasonable prices. To everyone who is currently building or renovating, I wish continued perseverance! Or to put it in the words of the former chancellor: We can do this! ;)

I honestly assumed that people here understand the basic rule of three and at least have a small sense for numbers... China currently has 1.4 billion people, which is 17 times as many inhabitants as Germany with 82 million. China has a nominal capacity of 1020 gigawatts in renewable energies, Germany 131. Put this into relation and you get the following values: China = 1.4 GW nominal capacity per 1 million inhabitants. Germany = 0.6 GW nominal capacity per 1 million inhabitants ==> As of today, China has 2.3 times the nominal capacity of renewable energies as Germany. China plans to bring new renewable energy plants (e.g., photovoltaics) with a nominal capacity to the grid this year that corresponds to the current total nominal capacity of all renewable energies in Germany. So the absolute and relative numbers will continue to shift in favor of China. Is this meaningful for you now or should I prepare the numbers for you differently?

Well, still more than half of China’s primary energy comes from coal! And 7% from renewables (excluding hydropower, which is 15%. China has comparatively high hydropower potential). For comparison: Germany had 16.6% from renewables in total in 2020.
