Case Study
Dysprosium is an essential element in the creation of permanent neodymium magnets. Dysprosium allows such permanent magnets to maintain their properties at high temperatures. Due to the high temperatures which exist inside electric motors and turbines, the main demands for dysprosium-doped magnets come from production of wind turbines and electric vehicles (Moss et al., 2011). Dysprosium is needed in order for these products to operate efficiently at high speeds.
As demands for green energy and green tech continue to rise, so does the demand for dysprosium (Department of Energy, 2011; Moss et al., 2011; Alonso et al., 2012) Projections show that the increases in use of green technology required to stabilize atmospheric carbon dioxide at 450 ppm would increase demand of dysprosium by 2600% over the next 25 years (assuming current demands for wind and electric motor applications are representative of future needs). However, current estimates show that production of dysprosium is predicted to increase by at most 6% per year. In order to meet the expected rise in demand, production would have to increase by more than twice as much, at a rate of 14% per year (Alonso et al. 2012). The figure below shows supply and demand projections for dysprosium until the year 2025.
Projections for Future Supply and Demand for Dysprosium, Based on Various Scenarios for Green Energy Demand

In the figure above, various demand scenarios are plotted against expected future supplies of dysprosium. It is crucial to note that for even the most optimistic of scenarios there is shortfall in future supply of dysprosium.

Unbiased article IMO however judge for yourself as I am biased towards NTU...
