On September 17, 2019, U.S. Senator Lisa Murkowski (R-AK) chaired a hearing to discuss the use and sourcing of minerals needed for clean energy technologies. Highlighting the fact that renewable technologies such as batteries and wind turbines are built from minerals, Senator Murkowski stated that “[t]he United States is capable of being a leader in the development of the minerals needed for clean energy technologies.” As Chairman for the Committee on Energy and Natural Resources, she further argued that for this to be achieved, the production, manufacturing, and recycling of minerals must expand to rebuild a robust domestic supply chain. In her opening statement, Senator Murkowski announced the release of a report by the Congressional Research Service. The report summarizes analyses of the quantity of materials needed to meet renewable and greenhouse gas (GHG) emission goals. The report includes an analysis of a World Bank Group (WB) study, which forecasts that demand for certain minerals will increase under an aggressive scenario to limit warming. The other two analyses in the report consist of DOE critical mineral demand projections and a gross domestic product (GDP) electricity demand study by Halada et al.
