Newly built single-family house - gas or air heat pump + photovoltaics + storage?

Why does the state promote heat pump technology and here only particularly efficient ones?

I understand what you want to say with that. But I do not necessarily deduce existing ecological awareness of the decision-makers solely from the fact of a subsidy or a political decision; this topic has been known for decades and yet they have promoted poison-spewing technologies from coal to combustion engines. When I recently saw the promotional video of the Minister of Agriculture together with Nestlé or, for example, the renewed postponement of piglet castration, etc., how should I as an ordinary citizen then find the belief that decisions in the residential construction sector are made solely for climate protection reasons? If that were the case, we would have, among other things, had a speed limit long ago.
If politics had truly understood the climate problem, it would have had enough opportunities across parties in recent decades to steer the wheel in a different direction; even Mr. Kretschmann does not get under the 500-series Mercedes, he did not even want to discuss it.

If gas is such an extreme killer, I would be in favor of completely banning its installation; then that’s just how it is because it is harmful to the climate!
But to even promote it indirectly through KfW, to build new pipelines, but at the same time to outlaw it, that doesn’t quite make sense to me.

When these questions have been answered, one should know what is currently societal consensus through the society via the elected representatives and thus a majority of the population.

Why is the possible gas heating outside the current societal consensus when the above-mentioned elected representatives precisely allow this gas heating as part of the KfW subsidy?

What I still have to get off my chest because I simply find it perverse. When I look at which "electric cars" are driving around here with us (and there are quite a few now because of Telekom, Post/DHL, Postbank/Deutsche Bank, United Nations, Bechtle, and others), it makes me sick. These are all big rigs, hybrids that have a tiny electric motor and a big combustion engine. Thick SUVs, luxurious limousines. They then think they are the game changers because they drive luxury cars subsidized by the state and provided by the employer, which can barely store enough electricity to get to the next [alnatura]. Double standards to the very end.

Pretty strange what is being put into my mouth here. Maybe you mean someone else? But fine. I’ll address it.

then you don’t consistently apply your ideology ;)

Which ideology? What do you mean?

For many home builders, 5-15k€ for a photovoltaic system is still too expensive.

Really? I don’t believe that. But we will see how the photovoltaic obligation on new builds will slow down the construction boom. And of course, 5-15k for a photovoltaic system is chosen very, very low. Almost always a “normal” house requires 20 kWp. So 20k. By the way, you can finance that completely separate from the house loan from the KfW. Ah, and it pays for itself. Thanks to a subsidy. So it ends up costing nothing. Saves money. Which other part of the house can do that?

If money is available, you can of course easier do greenwashing when building a single-family house.
It still doesn’t become “green” because of that.

With money many things become easier. And I find it makes you incredibly happy to buy something meaningful with it. What heat pumps and photovoltaics have to do with “greenwashing” I don’t understand.

Subsidies are usually not good. And just because they exist doesn’t mean it’s the only right way. Look through history what has been and is being subsidized.
Oh, fuel cell heating systems are also subsidized. But according to your view, that’s the wrong way.

All correct. Did I say otherwise? I believe we aren’t that far apart after all.

4,000€ gross family income and 2,000€ single person equals unemployed? Bold statement.

I don’t really know how that is supposed to be read from my posts. That’s certainly not what I meant. To clarify again: Here in the forum most certainly have a decent income, otherwise they wouldn’t be interested in building. Because building in 2021 is very expensive. And I ONLY address these people when I say: In 2021 you no longer build with gas, that is irresponsible.

Electric cars cheaper alternative, if a family-appropriate car costs around 40,000€?

A normal Golf at the end of its car life is cheaper as electric than as combustion. Yes. You can calculate that with a calculator. Many have already done so. What do you want to get at?

Photovoltaic system cheap? Can a normal earner afford a photovoltaic system at an assumed 1,200€ per kWp?
Probably not.

Yes. Sure. If you don’t have the money, you can borrow it. The monthly rates come back from the energy provider. Even after the loan is already paid off. Ah, and then you also save on electricity purchase. Whoever has a roof can also have photovoltaics. Or not calculate. BUT: I never claimed that. I said photovoltaic systems have become one of the cheapest forms of energy generation thanks to our Renewable Energy Act. Feel free to argue against that.

I stick to it, everything you say is right. But only doable for the top percentages of the population.
Serious environmental protection looks different.

The poorer, the less environmentally destructive the lifestyle, the lower the responsibility. A short recap: “People who newly build in 2021 (and obviously can afford somehow upwards of 350k €), please build with heat pumps.”

How much does a Golf electric car cost, please? I don't know. So fully electric, no hybrid. Also, not a family car for me. What use is a car to me that costs less at the end of its life (by the way, I thought this was about environmental protection and not about economic efficiency) but that I cannot afford to buy. Most people will probably spend around €6,000-17,000 on a car. Used.

Now I am debating after all. I didn't want to.

There are practically no used electric cars. So no need to discuss that yet. It's about new cars. And if someone needs a large van, they still can't find that as electric. So there's no need to discuss that yet either. Fine.

A single-family house is never ecological. That is what I meant by greenwashing in single-family house construction. In this case, luxury is more important to everyone here than the ecological consideration.
