A current topic that is greatly under-reported involves the critical shortage of "rare-earth" minerals. These elements are needed in all facets of technology and are especially important
in all forms of renewable energy. Simply put, this is a crises - a crises in which you have never heard of.
For a good overview of the end use of various kinds of rare earth minerals go HERE.
Much of the content of this material draws from two recent and comprehensive reports. Below is the reprinted abstract from
the European Union (EU) point of view:
Due to the rapid growth in demand for certain materials, compounded by political risks associated with
the geographical concentration of the supply of them, a shortage of these materials could be a potential
bottleneck to the deployment of low-carbon energy technologies. In order to assess whether such
shortages could jeopardise the objectives of the EU's Strategic Energy Technology Plan (SET-Plan), an
improved understanding of these risks is vital. In particular, this report examines the use of metals in the
six low-carbon energy technologies of SET-Plan, namely: nuclear, solar, wind, bioenergy, carbon capture
and storage (CCS) and electricity grids.
The study looks at the average annual demand for each metal for
the deployment of the technologies in Europe between 2020 and 2030. The demand of each metal is
compared to the respective global production volume in 2010. This ratio (expressed as a percentage)
allows comparing the relative stress that the deployment of the six technologies in Europe is expected to
create on the global supplies for these different metals.
The study identifies 14 metals for which the
deployment of the six technologies will require 1% or more (and in some cases, much more) of current
world supply per annum between 2020 and 2030. These 14 metals, in order of decreasing demand, are
tellurium, indium, tin, hafnium, silver, dysprosium, gallium, neodymium, cadmium, nickel, molybdenum,
vanadium, niobium and selenium. The metals are examined further in terms of the risks of meeting the
anticipated demand by analysing in detail the likelihood of rapid future global demand growth,
limitations to expanding supply in the short to medium term, and the concentration of supply and
political risks associated with key suppliers.
The report pinpoints 5 of the 14 metals to be at high risk,
namely: the rare earth metals neodymium and dysprosium, and the by-products (from the processing of
other metals) indium, tellurium and gallium. The report explores a set of potential mitigation strategies,
ranging from expanding European output, increasing recycling and reuse to reducing waste and finding
substitutes for these metals in their main applications.

And shortages lead to rapid price escalations meaning that some strategies suddenly are no longer cost effective:
Now its important to realize that the situation right now, (May 2015) has improved over the large panic in 2010-2011. The figure below shows the strong price spike that lead to supply concerns which have now been relaxed somewhat due to increased production (because it was cost effective at high prices). However, there is ABSOLUTELY NO REASON TO BELIEVE THAT THE IMMEDIATE FUTURE WON"T BE SUBJECT TO ANOTHER PRICE SPIKE - THIS ENTIRE ARE IS EXTREMELY VOLATILE:

The following table identifies supply chain risks. Note that many of these materials are also used in various medical technologies.
And there are now legitimate Lithium Concerns which is highly relevant to the production rate of EV's and PHEVs.

Below are a few details for some of these critical elements with the highest levels of risk:
One of the more serious problems is the use of certain rare earths as the major components for magnetic motors and generators. Neodymium is a primary requirement and one of the largest usages occurs in
the Toyota Prius
And finally, it is abundantly clear that CHINA completely controls the rare earth Market now and forever. This will undoubtedly lead to interesting political and economic dynamics in the very near future.
A recent global report
In sum, the lack of US access to rare earth minerals may well become the biggest obstacle to implementing large scale renewable energy sources within its boundaries. This is a serious problem. But don't believe me - here are some links to resources
that discuss this issue at some reasonable level of credibility:
