The Growing Demand for Copper in Energy Transition

Copper is emerging as a linchpin in the clean energy transition, with electric vehicles (EVs) requiring four times more copper than conventional cars. The U.S. imports 35% of its copper, primarily from Chile and Peru, where labor strikes and water shortages threaten supply stability. By 2030, global copper demand could outstrip supply by 6 million metric tons annually.

Copper-Intensive Technologies

• EV Charging Infrastructure: Each fast charger contains 8–12 kg of copper.
• Wind Turbines: Offshore units use 8 tons of copper per megawatt.
• Grid Modernization: U.S. electricity networks need 1.5 million tons of new copper by 2035.

Trade Policies Reshaping Mineral Flows

The U.S. Section 301 tariffs on Chinese minerals and the USMCA rules of origin are redirecting supply chains. For example, Canada now supplies 28% of U.S. aluminum imports, up from 9% in 2018. However, these shifts come with trade-offs—Canadian aluminum costs 15% more than Chinese imports.

Impact of Recent Trade Measures

Policy	Target Mineral	Effect
Inflation Reduction Act	Lithium, nickel	50% of battery minerals must be from US/FTA countries by 2027
CHIPS Act	Germanium, gallium	$52 billion for domestic semiconductor mineral security

Space Mining: The Next Frontier

Asteroids contain trillions of dollars worth of platinum-group metals and rare earths. Companies like AstroForge plan to test extraction technologies by 2026. While promising, space mining faces legal ambiguities—the 1967 Outer Space Treaty prohibits national appropriation but allows commercial exploitation.

Near-Earth Asteroid Mineral Estimates

• 16 Psyche: Contains $700 quintillion in iron and nickel (theoretical value).
• Ryugu: Sampled by Japan’s Hayabusa2, showed traces of cobalt and platinum.

Battery Passport Initiatives

The EU’s new battery passport requirement (effective 2027) will mandate full disclosure of mineral origins, carbon footprint, and recycling content. U.S. manufacturers exporting to Europe must implement blockchain-based tracking, adding 3–5% to production costs but enabling premium pricing.
