Yes, we could use some numbers here. I.e., how much energy would it take to grow one kg of potatoes in artificial lighting. Compared to how much it takes to transport it by ship from Morocco to Copenhagen. Or by an electrical train from Spain.

Production of electricity from wind turbines fluctuates a lot. So does the price. I wonder if there are plants that you can give light when it is windy at any time of the day and leave in the dark when when electricity is expensive.
