Actually from the ongoing energy consumption perspective it is more efficient to build solar-panels and feed the electricity into highly efficient LED lights for these plants, but the picture is less clear when considering the entire life-cycle costs of these very capital intensive vertical farms.
It’s mostly because they require a lot of electricity for lights, right? Because plants outside use the sun and inside there is no sun.
