The 15 lanthanides (or lanthanoids), [a] along with scandium and yttrium, are usually included as rare earths They play a critical role in energy. Rare earth elements (ree) are becoming increasingly important in electronic devices used in the defense, alternative energy, and communications industries
Minable deposits of rees are found in only a few locations. Despite their name, rees are relatively abundant in the earth’s crust, but rarely found in economically exploitable concentrations Department of energy’s office of critical minerals and energy innovation today announced a notice of funding opportunity for up to $134 million to enhance domestic supply chains for rare earth elements.
This beginner’s guide explores how rees power innovation, where they're found, their unique uses, and the global impact of demand, mining, and sustainable sourcing. They include the 15 lanthanide elements plus scandium and yttrium
