NEW YORK (
TheStreet) -- With the global stock markets naturally reacting terribly to the possibility of
Japan's nuclear situation going from disastrous to catastrophic, nearly every sector has suffered a beating.
That includes rare earth stocks.
In case you don't know, rare earths are a group of 17 metallic elements used in a plethora of consumer and industrial products. Many people don't know anything about them, but they're found in televisions, cars, cellphones, radar systems, fiber optic devices, wind turbines and many more.
Take the latter, for example. Rare earth elements are crucial to wind turbine manufacturing. Why? Because wind turbines contain very large magnets that are part of the generator that produces electricity from the spinning blades.
Each one-megawatt generator uses as much as one ton of rare earth metal, neodymium, as well as other rare earths.
Simply put, our way of life wouldn't be possible without rare earth elements. They're vital to all economies, including Japan's.
Trouble is, Japan is the largest importer of rare earths from China (which is responsible for 95% of global rare earth production), gobbling up about 50% of Chinese rare earth exports.
So what do you need to know?
Former Bank of Japan Deputy Governor Toshiro Muto says Japan's rebuilding costs from the current disaster could hit 20 trillion yen ($245 billion). That's double what it cost to rebuild after the Kobe earthquake in 1995.
That means demand for rare earth metals will increase... dramatically.
However, while Japan's demand will ratchet higher, the need for these metals isn't exclusive to the world's third-largest economy.
Take wind power in the United States, for example. U.S. Secretary of Energy Steven Chu and Secretary of the Interior Ken Salazar recently announced a major initiative to advance the development of offshore wind power.
And given the current nuclear crisis taking place, it's likely that the proposal will sail through Congress with little resistance. Particularly with President Obama having already announced a plan to produce as much as 80% of America's power from clean sources like solar, wind and nuclear.
