The essential similarity in the future perspectives of IEA and GTK is that electronic transportation corresponds to a very small part of the known mineral reserves. For example, copper need for electric transportation is only about 2.3% of the known global resources, according to the GTK estimate. That's where the similarities end, but there's no need to slow down the development of electric transportation in favor of metals. It will take at least 15-20 years anyway, even if all new cars are electric tomorrow.
