Around 2010, many commentators stridently warned that China''s nearmonopoly on supermagnet rareearth elements could make the growing global shift to electric cars and wind turbines impossible—because their motors and generators, respectively, supposedly required supermagnets and hence rare earths. Some such reports persist even in 2017.
Rare earth elements ("REEs") are a set of seventeen chemical include the fifteen lanthanides plus scandium and yttrium. Scandium and yttrium are rare earth elements since they are often found in the same ore deposits as the lanthanides and have similar chemical properties..
