Green technologies require huge amounts of many different raw materials. A methodology is presented to identify possible material bottlenecks. Bottlenecks are assessed through reserves, resources and production data. Annual increase in metal recycling rates to offset bottlenecks is calculated. 1. Introduction
Technologies which are affected by these bottlenecks are solar photovoltaic, with indium, gallium, selenium, tellurium and silver requirements, electric vehicles, that need cobalt, lithium, molybdenum and gallium among others, wind power which demands permanent magnets (i.e. REE) and solar thermal power that requires silver and molybdenum.
