Batteries are unsustainable and have massive resource requirements. It’s basically an obsession with “efficiency” while actually being extremely wasteful.
You say that while promoting the idea of more inefficient energy transfer systems. Electric motors operate above 90%, traditional motors around 25-30%. Trying to mitigate that with wasting more energy by creating an artificial fuel is even more wasteful.
Burning stuff is unsustainable, using batteries, that are recyclable is not.
Solar panels are only 15-20% efficient. No one is going around saying we need to ban solar panels.
Fuels made from solar power are the opposite of unsustainable. They are the most sustainable ideas possible. It is basically artificial photosynthesis.
Because it is solar power ultimately powering it all. If you don’t care about the efficiency of that step, you don’t really care about all of the later steps. It is still green energy and still cheap.
The problem with BEVs is that while it is efficient in one respect, it is insanely wasteful in others. As a result, it is an unsustainable idea and functionally just greenwashing.
Now we’re in the “pro-BEV bullshit” zone. Batteries won’t magically solve all transportation needs, nor solve the energy storage requirements of the grid. Alternatives still have to exist anyways, and the total lifecycle efficiency of BEVs isn’t that special. In a lot of cases, avoiding excessive use of batteries will save you energy. So pursuing alternatives will not need radically more solar panels.
Yeah, quit using the efficient stuff, we need something similarly inefficient as gas powered cars.

We don’t make fuels from solar power.
Unless you mean hydrogen, which by itself is already 30-40% less efficient then just using the electricity directly in a battery.
And that is without counting all the hydrogen that just escapes through any form of containment we try to keep it in.
Hydrogen is a fuel. E-fuels are hydrogen plus CO₂ and converted into synthetic hydrocarbons.
You are blatantly ignoring the part where solar power is incredibly inefficient to begin with, and we don’t care. It’s still cheap energy.
Where is the comparison to the solar panel? I’m comparing methods of propelling, you are comparing solar panels and?
If you can use the energy more efficiently and choose not to it’s not sustainable (or at least not very smart)

So it’s the same if you have to build 5 times as many solar panels to do the same thing? It’s just not.

Where did I say batteries were perfect?
