You misunderstand the expansion of wind and solar. But whatever. You can’t convince me with arguments anyway. If NOW (in winter) 50% green electricity is in the energy mix, then I also charge with 50% green electricity. I am not interested in future prospects in my current consideration.
Which by the way look like coal is becoming less and less.

Your statement was: In the dark season there is almost always 100% coal power. That is simply nonsense and just wrong.

I thought we have no gas power plants and 100% of the electricity comes from coal? At least, that’s what you write. Where does the gas come from suddenly? Oh yes, I make the world the way I like it.

And even if I were to charge for some months in winter with coal (subjunctive), I would still easily have 60% to 100% green electricity, since I produce it myself. With the worst case calculation in my own example I am still better than any combustion engine.

Yes, you charge with just under 50% green electricity, but in the same amount you are precisely taking that green electricity away from all other consumers. That makes you feel good, but you still have not reduced Germany’s CO2 emissions. How fortunate that "attitude" and "mental accounting" beat physical realities.

Yes, you load about 50% green electricity, but at the same time you take exactly this green electricity away from all other consumers in the same amount. That makes you feel good now, but you still haven't reduced Germany's CO2 emissions. How good that "attitude" and "mental accounting" beat physical realities.

Since the "physical reality" looks like this (according to your interpretation), that in the end everyone in Germany only charges 50/50 green/brown, I have no real problem with that. For me, it is all the more important that Germany already consumes 50% green electricity overall in winter and much more in summer.

Oh yes, when using only the mixed electricity, my statement remains:

By the way, an average car needs about 3-6 years with normal driving behavior if you charge exclusively according to the German electricity mix

P.S. Where did your 100% coal electricity in winter go? Is that no longer valid? And finally: who is supposed to give up green electricity so that "all other consumers" can then use it? What about those who take green electricity away from me. Those scoundrels...

Thanks. Who decides what is reasonable? It’s fine if chand considers travel valuable, other people enjoy the smell of fresh laundry. But that just doesn’t get into the minds of moralists, even if in the end supposedly no one wants to be one...
(...)

That said, you also have to put it into perspective. For a flight for 2 people to Mallorca and back, I can probably run my washing machine all year...

If you start comparing private pleasure flights, then they lose against everything. Trips to the bakery with a diesel car, meat consumption, daily washing. All peanuts compared to flights or even better cruises.

So let’s keep a low profile when it comes to judging the behavior of others.

100%
We have a legal framework within which we operate. Blaming each other within this framework is popular but ultimately poison for good coexistence. There is plenty of room.

Furthermore, people often have no idea how much energy is required for what.
An A320neo (e.g. from Germanwings) needs about 5.5 tons of kerosene from Cologne to Palma and transports 180 people (fully occupied).
This currently particularly efficient aircraft reaches just over 30 kg of fuel per passenger under ideal conditions (full occupancy).
A single-engine Diesel DA40 with 4 seats consumes on average about as much as a modern mid-size car.
I share this without judgment.

Yes, you charge nearly 50% green electricity, but at the same time you are taking exactly this green electricity away from all other consumers in the same amount. You feel good about that now, but you have not reduced Germany's CO2 emissions anyway. How good that "attitude" and "mental accounting" override physical realities.

For CO2 emissions, the pure overall balance of energy production (total) / energy production (CO2-free) is decisive. For the world, mind you.
So the idea that you are taking something away from someone when you drive electric instead of a combustion engine is physically wrong, because you shift something in the above fraction from the numerator to the denominator.

Logically, there are exactly two measures to reduce CO2 emissions: saving energy (lower the numerator), providing green energy (raise the denominator). All(!) other nettings against each other are unphysical misinterpretations. Energy conservation sometimes also has a simplifying effect.

The idea of "taking away" is already wrong for the simple reason that we currently have a massive surplus on windy and sunny days and ultimately have to shut down wind turbines and massively curtail solar plants to keep the grid stable.

It is also wrong because there is no energy transition without electric drives. It is completely absurd to believe that you will laboriously produce billions of tons of synthetic fuels with electricity and then burn them in combustion engines with 30% efficiency.

Apart from that... I drive my ID.4 with 22kWh/100km. That is quite a lot because I am constantly speeding on the highway. But 22kWh is just about 2.2 liters of diesel...
