"Green" energy of wind-another view

Promoting the use of renewable energy sources is important both to the reduction of the dependence on foreign energy imports, and in meeting targets to combat global warming. A solution to the problems of climate change, air pollution, water pollution, and energy insecurity requires a large-scale conversion to clean and reliable energy at low cost together with an increase in energy efficiency.For windpower, the most problematic materials may be rare earth elements(REEs) like neodymium(Nd) used in permanent magnets (PMs) in generators . Monazite is a primary ore of several rare earth metals most notably thorium, cerium and lanthanum. All these metals have various industrial uses and are considered quite valuable. Monazite is an extremely important ore mineral, but extraction of REE are potentially ecologically very damaging process.
