sun - NASA 2BSF – the pinnacle of sustainability

We often think of solar photo-voltaic generation of electricity as a prime example of sustainable technology, but how does it compare to bio-conversion represented by black soldier fly larvae (BSFL)? I think using virtually unlimited solar radiation to produce energy is significantly better that using fossil fuels, however, I believe using BSFL to convert waste into food (animal feed) is an even better model of sustainability. One of the reasons I feel that way is due to the potential environmental impacts of each technology. Below I’ve quoted one study of the risks involved in the manufacture and disposal of photo-voltaic panels:
