"While the benefits of electric vehicles certainly are appealing, there are unintended consequences not openly being discussed. Among these are “indirect pollution,” and “natural resources availability” related to the wiring, traction motors, and batteries that are the primary drivers of electric-drive vehicles.
Let’s begin with “indirect pollution” resulting from mining and processing of materials. Battery-pack materials include aluminum, copper, steel, lithium, glass fibers, carbon fibers, and polymers. Electric motor materials include aluminum, cobalt, copper, iron, silicon-steel, manganese, graphite, lithium, and a variety of rare-earth minerals (dysprosium, neodymium, niobium, terbium and praseodymium).
For example, the amount of copper required for electric-drive vehicles is staggering compared to that for fossil-fuel-powered vehicles. Conventional cars use 18 to 49 pounds of copper, while hybrid vehicles (HEVs) use 85 pounds. But it doesn’t end there. PHEVs use 132 pounds of copper, while EVs require over 180 pounds. Electric buses and hybrid electric buses contain 196 and 814 pounds of copper, respectively. And there’s a real cost for that.
Copper, much like other primary metals, begins with mining the metal bearing ore. Beyond mining, the process steps for producing copper include transportation, concentration, roasting, smelting, converting, and refining before it is ever formed into bus bars, terminals, connectors, and wiring. Those processes require massive amounts of electricity and result in large amounts of impurities and pollutants that must be contained and disposed of. These include sulfur, antimony, arsenic, lead, sulfur dioxide (SO2), sulfuric acid, iron oxide, and naturally occurring radioactive materials (NORM) such as uranium and radium. The waste streams include solution ponds, smelter slag, and solid waste.
Note, too, that “natural resources availability” of many of the metals required for electric vehicles is in environmentally sensitive regions, countries with unstable or economically hostile governments, and globally- constrained supply chains. Let’s take a look at where massive amounts of just three of those required minerals are found: cobalt, rare earth, and copper.
♦ Cobalt: The Democratic Republic of Congo possesses 47% of the global reserve. China processes the largest amount of cobalt for the world market. New cobalt reserves are being exploited. Deep-sea mining of metal nodules mixed in the sediment is one of the most promising sources of cobalt, copper, nickel, and manganese, especially among the Pacific Islands. Waste rock and sediment is re-deposited on the sea floor destroying deep sea marine life.
♦ Rare-Earth Minerals: China possesses 95% of the global rare-earth mineral reserves. The supply chain is constrained by geo-political forces and a volatile price history. Until the 1980s, the U.S. was one of the world’s largest producers of rare-earth minerals. Northeast Wyoming, home to one of the highest-grade rare-earth deposits in North America, is currently under development. However, China has increased production by more than 500% since 1990 due to that country’s substantial deposits and cheap labor. As China began to produce more high-tech products requiring rare-earth elements, the mining intensified. That mining, in turn, uses a mix of water and chemicals, which causes extensive water and soil pollution. China’s local and federal authorities have reportedly shut down illegal and small-scale rare-earth mining operations.
♦ Copper: Domestically, copper is mined in Arizona, New Mexico, Utah, Nevada, Montana, and Michigan. Internationally, Chile, though, possesses over 30% of the global copper reserves."
