- montalbano 7y agoIn addition to my other comment on amortising manufacturing pollution of electric cars, see the below scientific articles on the time required for energy payback of solar panels. Many people are investigating this. https://www.sciencedirect.com/science/article/pii/B9780123859341000374 https://www.sciencedirect.com/science/article/pii/B978012385... https://www.sciencedirect.com/science/article/abs/pii/S0038092X01000330 https://www.sciencedirect.com/science/article/abs/pii/S00380...
- vermilingua 7y agoThank you for these. The solar articles talk about the energy payback of the PV systems, but is this necessarily equal to the environmental cost to produce them? I would think that energy usage != CO2 cost, as energy may not factor in mining, refining, etc.
