Vertical farming seems to be to be the hydrogen power of agriculture. It works in theory, but it currently really only works for fairly niche situations and the effort to break through to economies of scale is pretty intractable. Energy use is one reason; cost and profitablity is another. Compared to the alternative (making traditional agriculture better, improving electric vehicles), there's much less low hanging fruit.
