The electrification of things formerly powered by gas, petrol or diesel, be that motor vehicles, machinery or heating, in homes, in factories, on farms and indeed in mines, will require more metals. The classic example is the battery-electric vehicle. These cars require upwards of three times the amount of copper of an internal combustion engine vehicle. You then need battery metals such as lithium, nickel and cobalt, and a variety of hard-to-get rare earth elements for the magnets in the motors. But in addition to the metals in the vehicle itself, you also then need to charge it up. That requires even more metals, mostly copper and steel, to construct and then run the power supply to all the vehicle charging points. And then you need even more metals, again mostly copper and steel, to augment the electricity grid network so it can cope with all the extra demand coming from all that electrification. Finally, you need to increase the amount of electricity you are producing to meet that extra demand. All these metals start as ore mined from under the ground and then processed and refined into the metals we need such as copper, steel, aluminium, nickel, and so on.
