How much glass is needed for terawatt-scale PV?

German scientists have assessed demand for resources such as glass and silver until 2100 and have found that current tech learning rates could be sufficient to avoid supply concerns.Researchers at Germany's Fraunhofer Institute for Solar Energy Systems ISE and the Potsdam Institute for Climate Impact Research (PIK) have tried to estimate how much float glass the PV industry may need to help the world reach the terawatts of installed solar capacity that will be necessary to reach ambitious climate goals and limit global warming to 1.5 C. The scientists outlined two different scenarios: a conservative ...
