        oh that yeah of course i saw it :D

        but that’s not why i said it. I did my own calculations here:

        Biodiesel takes much more area because the efficiency is much lower because plants metabolism isn’t so efficient, like iirc sth like 0.3% of sunlight energy end up in the fruits of the plants, compared to 20% efficiency for solar panels.

          Is it me or does it look genuinely possible when most rooftop space is not being actively used?

            i’m personally also against rooftop solar, partially for aesthetic reasons but more importantly for financial reasons:

            flat-area solar parks are significantly cheaper than rooftop solar (source 1, source 2), and they also don’t require a lot of land area (see comments above).

            “utility scale” and “PV frei” means flat-area ground-based solar parks, while “PV klein” and “PV groß” mean rooftop solar (small/big). “Stromgestehungskosten” means levelized cost of energy.
