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

Somehow I need a smiley here that cries and laughs...

The discussion is actually obsolete as of today - gas will still be important in the coming years because the expansion of renewables is progressing far too slowly. Because if everyone switched to electric cars and heat pumps in the next few years, even just the new buildings being constructed, the lights would go out by November at the latest, or coal power plants would have to generate electricity to meet demand.

No greenwashing heat pump green electricity tariff will help then. The CO2 will still be emitted.

So let's see where the energy transition stands in 15 years. That will be decisive.

I am not an expert. But isn't it actually the case that we already produce so much electricity from renewable energy that we have to sell it, and that is only because our grid cannot handle the fluctuations? If that is true, then demand should not be the problem, but the grid, right?

On a July day, the demand is certainly no problem - but at 5:00 PM in the gray November, it probably is. Where is the electricity especially in the windless south supposed to come from then?

Grid? From wind turbines in the north? Hydropower plants? And (I’m coming clean) nuclear power? I mean it was in Belgium, soon the first plant will go online that recycles the generated waste? Edit: the keywords and transmutation as well as particle accelerators lead to the mentioned.

A very nice discussion.

I deliberately chose a gas heating system in my new building (moved in at the end of 2018).

What led to this extremely conscious decision?

However, environmental protection cannot always be carried on the backs of the middle class.

Hmm, didn't we already establish a few pages earlier that it is not actually more expensive?!
But since you consciously decided, can you certainly say again which option would have cost what for you?
