I don't see how vertical farming can make sense. There is only so much sunlight striking the ground and you just changed the angle and so shaded something else.
Artificial lighting exists.
Let's assume the energy for lighting comes from solar. Panels are only 20% effective. Now your vertical farm needs 5x the space of a basic farm, and you still have to pay for power instead of using free sunlight. There is some video on YouTube from a salt lake city university professor who works for nasa on growing plants in space about this topic.
Sure. The solar panels don’t need to be next to it, but can be anywhere. Solar panels can even be used on traditional agricultural fields while still growing vegetables or grazing animals. Using solar panels on surfaces like roofs or above parking lots is another way of placing them without using additional ground.
