Construction costs are currently skyrocketing

Ah, because you just keep repeating it, does it become more correct? So when I google what happens if everyone has an electric car instead of a combustion engine: Germany's electricity consumption increases by 10%. Currently, we export 8%. Yes, maybe we have to start managing everything a bit smarter to have it at the right time in the right place. But none of that sounds problematic. Or what scares you?

It's not just about electric cars. You also want to heat every house with an electric heat pump. How is this electricity supposed to be produced "green"? ;)

Realism is sometimes mistaken for a lack of imagination and a refusal to question things down to their essence. Sometimes also for clinging to the familiar.

There is so much truth in your sentence. Very good.

The ratio of existing buildings to new construction is about 10:1 (!!!) You simply can't electrify everything. That is absolutely unrealistic! Also think about the electricity supply. The grids are already more than overloaded... Especially if at some point we all have to switch to electric cars.

Even if you think about hydrogen (it’s also a gas!), that can only work if all existing gas pipelines are replaced (who is supposed to pay for that?). Unfortunately, the existing gas pipelines are not suitable for H2. Besides, H2 is about 3 times more expensive than natural gas.

When you think about climate goals, you must not only think about single-family houses. They are negligible in the overall consideration...

So many concerns in one post. Actually the perfect example of what Hampshire wrote. It is astonishing what humanity has achieved so far in its history, only to apparently let further development fail because of a piece of copper and gas pipes in this case.

From a very short-term perspective, your concerns might be valid, but I think future society will no longer be able to understand your concerns.

The fact that single-family houses cause only a small part of the climate problems does not justify not paying attention to them at all. I really cannot understand such statements. There is always someone who does something even worse than oneself, but that’s how we all remain stuck in place.

The fact that single-family houses cause only a small part of the climate problems does not justify not paying any attention to them at all. I really cannot understand such statements. There is always someone who does things even worse than oneself, but if we keep thinking like this, we will all remain stuck in place.

Where did I write that one should not pay attention to it? My point is only that a holistic concept with purely electric operation of heat generators, e-cars, and other consumers (which will certainly increase in the future) will not be feasible in the near future, and therefore gas as an energy carrier will also play a role. Especially in existing buildings. Of course, something must be done, but at the same time one must remain realistic ;)

In Germany, around 1 million heat pumps were sold in 2021, with numbers expected to rise in the coming years. Calculate the electricity demand yourself...

I have nothing more to say on this and don’t want to spoil the thread any further ;)

The nice thing about electricity is that it can be generated universally. Even the Greens realize that gas power plants are needed during the transition. In internal combustion engines, about 75% of the energy is lost as heat, so only a small part goes into motion. The electric motor has a much higher efficiency. In the worst case, we no longer pour the gasoline into the car tank but convert it into electricity in power plants as efficiently as possible to power cars.

It is already being discussed whether the nuclear phase-out, combined with the increasing electricity demand, makes sense.

I have an idea for a bridge back to the topic: The trigger was the high emissions from cement production. How can they be reduced? With hydrogen. And that is exactly why it certainly won’t flow into any private tank for the next 30 years. (Burning banknotes would actually be the cheaper way to drive/heat. ;-) But what do we need to produce the hydrogen for the cement? Electricity. So cover your roofs completely and dry out the swamp of corruption among the wind power blockers! Otherwise, the next foundation slab will no longer be affordable.
