Solar panels + lights together are a system for redirecting energy, and the efficiency “loss” is inconsequential. You can simply cover an adjacent area 10x the size to provide the extra sunlight.
- jodrellblank 4y agoBut then why not cover the adjacent area with crops and sod the vertical farm, solar panels, grow lamps, wiring, and all the costs, construction time, maintenance work, etc. and just have a farm?
- voakbasda 4y agoBecause good land itself might just be more expensive to purchase and maintain than all of those systems in a highly dense footprint?
- curi0sity 4y agoInstead of an adjacent area, the panels could be in an arid desert. Meanwhile, the vertical farm is in a population center and using less water
- dredmorbius 4y agoThat is equivalent to saying "vertical farming is cost-effective where energy is free and land is scarce and expensive". Oddly enough, precisely the opposite circumstance describes most farming.
