What Are Critical Minerals and Materials?

The Energy Act of 2020 defines a “critical material” as:

  • Any non-fuel mineral, element, substance, or material that the Secretary of Energy determines: (i) has a high risk of supply chain disruption; and (ii) serves an essential function in one or more energy technologies, including technologies that produce, transmit, store, and conserve energy; or
  • A critical mineral, as defined by the Secretary of the Interior.

The Energy Act of 2020 defines a “critical mineral” as:

  • Any mineral, element, substance, or material designated as critical by the Secretary of the Interior, acting through the director of the U.S. Geological Survey.

Energy Critical Materials List

Pursuant to the authority under Section 7002(a) of the Energy Act of 2020, the Secretary of Energy determines the Critical Materials List. This list includes critical materials for energy, as determined by the Secretary of Energy in the amendment of the Critical Materials List and Final 2023 Critical Materials List, as well as those critical minerals on the 2025 final list published by the Secretary of Interior, acting through the director of the U.S. Geological Survey.

The Results of the 2023 DOE Critical Materials Assessment

A matrix chart showing different minerals, assigned as "critical, near critical" and "not critical" classes. The X axis shows supply risk, from low to high, and the Y axis shows importance to energy, from low to high.

Medium-term (2025–2035) criticality matrix

The Final 2023 Critical Materials List includes all materials that were assessed as “critical” or “near critical” in either the short or medium term, with the exception of uranium. Section 7002(a) of the Energy Act of 2020 restricts the listing of critical materials to “any non-fuel mineral, element, substance, or material.” Based on the plain meaning of fuel, uranium used in commercial nuclear reactors is a fuel material. As the 2023 DOE Critical Materials Assessment includes only use of uranium as a fuel, DOE did not designate uranium as a critical material in the Final 2023 Critical Materials List.
