Crs Report for Congress Rare Earth Elements
Crs Report for Congress Rare Earth Elements by Marc Humphries, published by BiblioLife in November 2013, is a concise exploration of the production and supply vulnerabilities associated with rare earth elements (REEs). This 34-page report addresses critical questions regarding the United States’ reliance on imported REEs, which are essential for new energy technologies and national security applications. The text outlines the composition of REEs, including the 17 elements that fall within the lanthanide group, and discusses the implications of the U.S. becoming fully dependent on foreign sources, particularly from China.
Readers will find a detailed examination of the significance of REEs in relation to U.S. economic well-being and national security. The report highlights the moderate abundance of these elements in the earth’s crust, while also noting the economic challenges in their exploitation. By focusing on the geopolitical and economic factors surrounding REE production, this edition provides insights into the complexities of supply chains and the potential vulnerabilities faced by the United States in securing these critical resources.
Official synopsis Publisher
The concentration of production of rare earth elements (REEs) outside the United States raises the important issue of supply vulnerability. REEs are used for new energy technologies and national security applications. Is the United States vulnerable to supply disruptions of REEs? Are these elements essential to U.S. national security and economic well-being? There are 17 rare earth elements (REEs), 15 within the chemical group called lanthanides, plus yttrium and scandium. The lanthanides consist of the following: lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, and lutetium. Rare earths are moderately abundant in the earth’s crust, some even more abundant than copper, lead, gold, and platinum. While more abundant than many other minerals, REEs are not concentrated enough to make them easily exploitable economically. The United States was once self-reliant in domestically produced REEs, but over the past 15 years has become 100% reliant on imports, primarily from China, because of lower-cost operations.
