The modern economy relies on a menu of “critical minerals,” like the lithium used in batteries and the rare earth metals in powerful magnets. Obtaining those materials involves both economic and geopolitical risks. But a recent study found that much of the critical mineral material we need is already here, in unprocessed byproducts and waste from existing mines.
Mining engineer Elizabeth Holley joins Ira to explain the different options for accessing these critical minerals, and how recovering even a small percentage of the material already mined could reduce the need for certain mineral imports.
Then, Lacey Shaver joins to discuss solar power, and how changing state regulations are allowing the growth of “balcony solar” or “plug-in solar,” small solar power systems that can be connected to a home electrical outlet.
