Hmm no,

• first oft all: noise. Wind turbines have moving parts, that attached to a building or even worse attached to a balcony creates noise in the whole building. Imagine the rattling of 5-6 ~10 year old, bad maintained, wind turbines.
• Second: the energy output is rather low. A 1,2KW turbine is about 1.2m/3.9feet big. That’s in spherical, cause it has to be able to rotate by wind direction.
• Third: balconies are preferred to not have wind, but sun.
• And last but not least: blades. Every windturbine form factor has (fast) moving blades. If it’s reachable someone is going to stick a finger in it.

If you’re living more suburban and have a windy detached place to setup a small windturbine that’s an option. On the garage or shed for example.

Except when no one wants shovels anymore.

I’ve heard it both ways

There are some factors to consider:

• They have a law called “schuldenbremse” since 2011 that forbids the state to take loans for investment/subventions. That kind of worked as intended https://de.statista.com/statistik/daten/studie/154798/umfrage/deutsche-staatsverschuldung-seit-2003/ but not investing at low interest rates (2010-2020 at ~1%) is controversial among economists. Also at corona there was a exception.
• Germany’s economy is export based. Now almost every country is struggling with post corona effects. Therefore everyone tries to support their local businesses. Germany has the schuldenbremse.
• The real estate market was about 40% overvalued and bureaucracy with corona did it’s best. Now the market is struggling to keep alive. No seller accepts the lower prices, banks already adapted and demand high securities. More people have to rent, rent rates hike, people struggle with rates and don’t consume as much.

As personal experience: My wife and me are struggling to get a home in the range ~500-800k, we got 20% down payment and with income we are in the upper 10% of all dinks in Germany. Still struggling to get a home worth the price and getting credit for.
