Experience with KFW55 solid + gas + 5 sqm solar

I think you just have to read into the subject a little #Energiekosten.
Besides, age plays a huge role.
I am under 30 and will live and heat this house for a very long time.
But if someone is already 50 years old, they don’t need to insulate as much to have affordable energy costs in retirement.

For example, in 40 years I will be 70 and retired. Currently, I pay €30 monthly. Energy costs increase by 7.5% per year. My pension is, let’s say, €1800.
The €30 will rise to €500 monthly in 40 years. That leaves €1300 remaining.
Won’t that happen? Yes! After all, I don’t have a crystal ball. But energy costs rise, and the longer the period, the greater the difference. For these reasons I chose kfw55. Maybe exaggerated today, in 40 years I will probably regret not having built a passive house… or at least be glad about the E55.

Yeah. Either the energy transition bears fruit and energy becomes cheaper than ever. Or you put a few solar panels, a wind turbine, and a battery pack in your place and become self-sufficient. Then you'll be pretty annoyed that you chose a passive house with 60 cm wall thickness...

Who knows...

Nuclear power plants off Fossil power plants should be reduced Electric mobility is coming more and more I am very glad not to heat with electricity that will be really fun when most new cars are electrified in 10 years! The amount of electricity "burned" there is huge Is that wind turbine meant seriously? Nobody would put something like that in their garden, right?! LOL

The thing with electric cars isn’t so bad. We in Germany only need about 10% more electricity than now. So no big deal.

And many people do the wind turbine thing. You just shouldn’t imagine the 100 meter tall offshore parts. There are plenty of small, quiet solutions that deliver around one kW of power. Unfortunately, the technology is still quite a bit less economical than solar because the quantities are still extremely low. But the topic was "in 40 years"...

I recently read that small wind turbines are economically disastrous. They have to be a certain height (over 30m?) for it to be interesting. And nobody can manage that in their garden.

Regarding the topic of rising electricity costs – who knows. Fossil fuels will be affected first because the transition will be subsidized. CO2 tax says hello; all "combustion engines" – whether cars or gas boilers – will have a lot of fun getting rid of old devices. However, the period will be typically long before such major pain is caused. Much too long.

There must be an area designated for wind power in the construction zone, which developers operate jointly; in SH this would provide almost 100% supply security. There are hardly any days without wind.
