A set of crucial questions arise as the demand to use of EVs, solar power, and wind energy increases: Is there enough supply to match the rising demand for critical metals? Where do we get these metals from and how? What are the actual repercussions of mining them? This article focuses on copper, one of the most important metals in the market for renewable energy. Its essential qualities enable electric vehicles to function and serve as a framework for energy storage systems. 

For thousands of years, the versatile and essential metal copper has been essential to human civilization. Copper is thought to have been used by humans for the first time around 10,000 years ago according to archaeological evidence. Copper’s importance continues to be unmatched, from prehistoric tools and coins to modern construction and technology. 

Significance of Copper 

Copper is a key component in electrical wiring, motors, and electronic devices due to its exceptional thermal and electrical conductivity. Electric motors are built primarily with copper, which is used largely in the windings. Strong magnetic fields can be generated inside the motor thanks to copper windings, which enhances torque, acceleration, and the overall performance of the EV. Copper is also used in electric vehicle battery systems. Copper is present in the anode and cathode materials of lithium-ion batteries, the most common type used in EVs.  

Copper in EV Charging Infrastructure  

A reliable charging infrastructure is necessary for all these new electric vehicles to become an economically viable form of transportation. Cables and connectors used for charging are made of copper. Due to copper’s high conductivity, EVs can be charged quickly and effectively, cutting down on the time needed to recharge the battery and enhancing overall convenience for EV owners. 

Supply and Demand of Copper 

The demand for copper will likely rise significantly as the uptake of electric vehicles continues. Copper is becoming even more crucial for the EV industry as transportation shifts to cleaner and more environmentally friendly modes of transportation. 

Sourcing Copper 

Mining and recycling are the two primary sources from which copper is primarily obtained. Large copper deposits can be found all over the world, with Chile, Peru, the Democratic Republic of the Congo, China, the United States, Russia, Indonesia, Australia, Zambia, and Mexico among the major producers. The extraction and processing of these copper ores results in refined copper that is ready for industrial use. 

Copper recycling has also become more popular because of its favorable effects on the environment and economy. In addition to lowering the need for new mining, recycling copper also uses less energy than primary copper production. The industry has come to rely heavily on copper recycling as the importance of sustainability has grown. 

In some nations, copper mining can have negative effects. Environment issues can arise in countries with heavy mining, such as Chile and Peru. The waste produced by the mining process can be harmful to the land, water, and plants and animals. Additionally, it causes deforestation, which entails the removal of trees and the destruction of animal habitats. In some cases, disputes over resources and land can even arise because of mining.
