MIT study finds unprecedented production of metals needed to meet some solar energy goals.

Several government agencies, academic researchers, and firms have proposed scenarios for the future in which photovoltaic (PV) technologies grow rapidly. To support such growth, PV technologies would need to be developed with resource constraints in mind. For some PV technologies, the production of the required input materials would need to grow at a rate never before seen in the metals industry, according to a new analysis by MIT researchers.  …
