> Artificial lighting saves land because plants can be grown above each other, but if the electricity for the lighting comes from solar panels, then the savings are canceled out by the land required to install the solar panels. Is this true? Plants use specific ranges of light (narrow bands of red and blue). Solar panels absorb a broad array of wavelengths. So isn't it at least possible that one solar panel could produce more than its size worth of productive sunlight for the purposes of photosynthesis?
