The dark side of renewable energy | Earth Journalism Network

Rare earth metals, hard-to-find materials, with unfamiliar names such as lanthanum, neodymium and europium, are used in wind and solar energy projects, but dwindling supplies could hinder a roll-out of low carbon technologies and slow China's shift away from coal power. These compounds, which are highly toxic when mined and processed, also take a heavy environmental toll on soil and water .
