Rare Earth Elements In Solar Panels

Neodymium is a so called rare earth element a silvery metal with a very important role in renewable energy.

Rare earth elements in solar panels.

This means that global production of several rare earth minerals used in solar panels and wind turbines especially neodymium terbium indium dysprosium and praseodymium must grow twelvefold by. For example a single tesla vehicle requires about 15 pounds or a bowling ball s worth of lithium and thin cheap solar panels need tellurium one of the rarest elements on earth. In 2011 the average price of rare earth metals shot up by as much as 750 percent. 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 hindera roll out of low carbon technologies and slow china s shift away from coal power.

However recent research coming out of the netherlands has spotted a red flag to relying on solar panels as a panacea for global emissions problems.

Terbium and europium are used in thin film solar panels while dysprosium is used to manufacture batteries in most hybrid gas electric. Rare metals are especially vital for renewable energy technologies such as electric cars and solar panels.

When combined with iron and boron it makes strong magnets that are important both for. Rare earth elements are 17 elements found on earth. High performance batteries need lithium which is only easily extracted from briny pools in the andes. Thin film pv technologies for example contain potentially critical metals such as tellurium.

However a lack of rare earths does not mean that the components of solar modules are harmless.
