Fig. 1: Metal footprints (MFs) of the renewable power demand by metal types in 2015.
From: Tracing metal footprints via global renewable power value chains
Top ten economies in MFs of a hydropower, b wind power, c bioenergy, d solar photovoltaic (PV), e geothermal power, f solar thermal, g ocean power. Among all economies, the top 10 economies with more than half the global MFs for each renewable power demand are included unless the MFs = 0 (for additional economy MFs, see Supplementary Fig. 3).
