Like, you’re joking but this is an actual thing. It’s called biofuel.
Basically they turn maize and other crops into fuel that you can fill into your car where it will be burned. This obviously means that the more biofuel we produce, the less food we produce, because both take up the same area, and the area availability is what’s limiting food production.
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.
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.

And it’s orders of magnitude less efficient than just using that land for solar panels.
but can I light the solar panels on fire?
do you want to?
IIRC solar panels produce about 100x as much energy for the same area than biodiesel.
I think we all saw the same video from the Christmas lights activist
what video?

oh that yeah of course i saw it :D

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

Someone best me to it lol
Which in turn still damages the environment more, because you need more surface and you spray it with chemicals. Bio fuel is not green.
