The production of minerals such as graphite, lithium and cobalt will have to increase by 500% by 2050 to meet the growing global demand for clean energy. This is the main information in the report “Minerals for Climate Action: The mineral intensity of the clean energy transition” published by the World Bank.
According to the study, it will take more than 3 billion tonnes of minerals and metals to set up the solar, wind and geothermal infrastructures necessary to reach the objective of limiting global warming to less than 2 ° C. However, experts say, the carbon footprint of extracting these materials will represent only 6% of greenhouse gas emissions from fossil energy technologies for an equivalent amount of energy.
The report also highlights the important role that mineral recycling and reuse can play in meeting growing demand. This contribution will certainly be important for minerals such as copper or aluminum that can be 100% recycled, but it will not be sufficient.
