Responsible Minerals Sourcing for Renewable Energy

By Elsa Dominish, Sven Teske, and Nick Florin - Institute for Sustainable Futures, 2019

The transition to a 100% renewable energy system is urgently needed to meet the goals of the Paris Climate Agreement and increase the chance of keeping global temperature rise below 1.5 degrees. Renewable energy technologies are now the most cost competitive technologies for new installations – and recent investment in new renewable energy infrastructure globally has been double that of new energy investment in fossil fuels and nuclear.

Renewable energy technologies, electric vehicles and battery storage require high volumes of environmentally sensitive materials. The supply chains for these materials and technologies need to be appropriately managed, to avoid creating new adverse social and environmental impacts along the supply chain.

This report presents the findings of an assessment of the projected mineral demand for fourteen metals used in renewable energy and storage technologies, the potential to reduce demand through efficiency and recycling, and the associated supply risks and impacts. Solar photovoltaic (PV) and wind power have been chosen for this assessment because these two technologies make up the majority of new global renewable electricity installations. Batteries have been assessed because of their importance for use in electric vehicles (EVs) and energy storage systems.

This research aims to identify the main ‘hotspots’ or areas of concern in the supply chain, including technologies, metals and locations, where opportunities to reduce demand and influence responsible sourcing initiatives will be most needed.
