People are obsessed with efficiency because it’s the only metric that matters. We have a finite amount of resources on this planet and efficiency is the only way we can make it last. If you aren’t a ‘save the planet’ type of person then efficiency still matters because it’s directly correlated with cost.
You are comparing different efficiencies. Solar panels are 15% to 20% efficient at converting light into energy. As far as I’m aware every Efuel being developed (and every hydrocarbon fuel for that matter) has a 0% efficiency at converting light into energy but if I am mistaken please do correct me.
In a completely technical sense the hydrocarbon fuel was at one time produced from light energy (dead plants) but that’s taking your point and being pedantic since the “efficiency” of the conversation is probably astronomically low when you account for the loses sustained by whatever lifeform died and became said hydrocarbons.
You avoid the giant, expensive battery though. People are obsessed with efficiency in a self-defeating way.

Better ban solar panels cause they’re only 15-20% efficient. /s

E-fuels are made from solar power. It is not anywhere near 0%. Also, clearly efficiency is not “the only metric that matters.”
