The U.S. Could Run Out of Metals That Are Crucial to Tech
Entire industries, including consumer electronics, may be disrupted
Technology has made us dependent on an alphabet soup of rare minerals sourced from the far corners of the planet. But there’s no guarantee that we’ll always have reliable supplies of these crucial resources. Now, scientists with the United States Geological Survey have identified a shortlist of 23 minerals that pose the greatest “supply risk” to U.S. manufacturers — minerals that, if unavailable, could upend entire industries, including consumer electronics, and set back efforts to combat the climate crisis.
The study, published Friday in the journal Science Advances, shows the surprising variety of metals American industries have a tenuous supply of, from familiar names like aluminum to obscure elements like dysprosium. The risk of supply shocks can be reduced, the authors say, by shoring up domestic supplies of these minerals, devising new manufacturing techniques, and beefing up recycling technologies. Experts, however, caution that efforts to develop additional supplies could result in increased instabilities overseas and new environmental risks.
The USGS scientists evaluated the supply risk of 52 minerals for which good data was available between 2007 and 2016. For each, they…
