Rare Earth Elements, a classification that includes the Lanthanides and Actinides.
Click on the following links:
Avalon Rare Metals
Molycorp Minerals
These metals are used extensively in the electronics industry and are a major player
in many green technologies and military defense.
Although these elements are not as rare as once believed, they have economic, envrionmental and political importance.

Examples include:
Lanthanum, found in hybrid car batteries
Europium, which may someday be used in LED-based lights as
an energy-efficient replacement for incandescent and fluorescent bulbs
Erbium, used in optical fibers to transmit information across the globe and
to produce low-heat medical lasers
Neodymium, to produce strong, yet light, magnets for use in electric motors that power
anything from small gadgets to computer hard drives and wind turbines.
