Secure supplies of critical minerals are required to expand U.S. energy infrastructure and power technologies such as artificial intelligence and advanced manufacturing. Critical minerals including copper, lithium, graphite, nickel, cobalt, and rare earth elements serve as building blocks for electric vehicles (EVs), battery storage, transmission lines, and next-generation nuclear reactors. According to the International Energy Agency (IEA), these minerals are indispensable to clean energy transitions.
While the U.S. possesses significant domestic deposits of these materials—including lithium in Nevada, copper in Arizona, and cobalt in Idaho—the current development timeline for new mining projects can exceed 15 years. Data from S&P Global indicates that companies frequently encounter overlapping reviews and lengthy litigation under the National Environmental Policy Act (NEPA). The Congressional Research Service has documented these complexities, which can lead to extended periods of uncertainty before construction begins.
The global supply chain for processing and refining these minerals is currently led by China. This reliance on foreign suppliers affects the production of both consumer technologies and national defense systems, such as fighter aircraft and communication electronics. Domestic interest is growing in projects like the Thacker Pass lithium mine in Nevada, which is expected to begin operations in 2027, as part of an effort to strengthen domestic mineral supply chains.
The scale of the challenge involves billions of dollars in potential infrastructure investment and thousands of jobs for engineers, scientists, and skilled workers. The current 15-year development timeline for new mines means that decisions made today regarding permitting and exploration will not result in new domestic mineral supplies until the early 2040s. A person working in the manufacturing sector or a student entering a technical field would notice these effects through the availability of domestic employment opportunities in processing plants and research facilities.
If the U.S. continues to rely on foreign processing, particularly from China, it remains vulnerable to geopolitical disruptions that could impact energy prices and national security. The knock-on effects include the ability of the U.S. to meet its stated goals for expanding the electric grid and deploying advanced nuclear technologies. What happens next depends on whether the federal government modifies its permitting systems to be more predictable and if investments in advanced mapping and domestic processing capacity increase. The Thacker Pass mine project is a key milestone to watch, with its scheduled opening set for 2027.
