Context:
The rapid expansion of the Electric Vehicle (EV) market has significantly increased global copper demand, raising concerns about a structural supply deficit by 2026, potentially affecting decarbonisation goals and clean energy transitions.
Key Highlights:
Rising EV Sales and Copper Consumption
• Global EV sales:
– 0.55 million (2015) → ~20 million (2025 estimate).
• Copper consumption linked to EVs:
– 27.5 thousand tonnes (2015) → 1.28 million tonnes (2025).
Projected Supply Deficit
• 2024: Supply exceeds demand by ~0.3 million tonnes.
• 2026 Projection:
– Demand: 30 million tonnes
– Supply: 28 million tonnes
– Indicates a 2 million tonne shortfall.
Elasticity Trends
• Copper demand elasticity w.r.t. EV sales > 1.0 (2016–2024).
• Implies copper demand grows faster than EV adoption.
Geographical Concentration
• China accounts for ~60% of global EV-based copper demand.
• Controls over 70% of battery cell production.
• Strongly integrated EV supply chain.
Supply Constraints
• Declining ore grades.
• Long project gestation period (up to a decade).
• Environmental opposition in mining regions.
Relevant Prelims Points:
- Copper Uses:
– Electrical wiring
– EV motors and batteries
– Renewable energy infrastructure - EVs require 2–4 times more copper than conventional vehicles.
- Elasticity of Demand:
– Measures responsiveness of quantity demanded to change in another variable.
– Elasticity > 1 indicates proportionally larger response. - Major copper producers: Chile, Peru, China, DRC.
- Copper is critical for energy transition technologies including:
– Solar panels
– Wind turbines
– Power grids - Decarbonisation refers to reduction of carbon emissions through clean energy transition.
Relevant Mains Points:
- Economic Implications
• Supply shortages may increase copper prices, raising EV production costs.
• Could slow EV adoption and delay climate commitments.
• Trade imbalances may deepen due to supply concentration. - Strategic & Geopolitical Concerns
• China’s dominance in battery and copper-linked supply chains increases strategic vulnerability for other nations.
• Resource nationalism and mining regulations may affect global markets. - Environmental Dimension
• Mining expansion may cause:
– Deforestation
– Water stress
– Social displacement
• Tension between green transition and extractive environmental costs. - India’s Perspective
• India’s EV push under FAME scheme and energy transition goals may be impacted.
• Need for securing critical mineral supply chains.
• Scope for recycling and circular economy models.
Way Forward:
• Diversification of supply sources.
• Investment in copper recycling and urban mining.
• Strategic mineral reserves.
• Technological innovation to reduce copper intensity.
• International cooperation on critical minerals security.
