1. Introduction

The geopolitics of electricity technology materials concerns the political, economic, legal and strategic competition surrounding the minerals and processed materials required to manufacture modern electricity technologies. The electricity transition is increasingly dependent on materials such as copper, lithium, nickel, cobalt, graphite, manganese and rare-earth elements used in batteries, electricity grids, wind turbines, solar PV systems, transformers, power electronics and permanent magnets.

The geopolitical importance of these materials arises because their mining, refining, processing and manufacturing are geographically concentrated. The International Energy Agency reported in 2026 that demand for key energy minerals continued to grow strongly in 2025, driven by batteries, grids, wind turbines, solar PV and other electricity technologies. (IEA)

Consequently, energy security is no longer concerned only with access to oil and gas. It increasingly includes secure access to critical minerals and technology supply chains.

2. Meaning and Scope

The expression can be understood through four interconnected layers:

Resource geography – where minerals are extracted.

Processing geography – where ores are refined and converted into usable materials.

Manufacturing geography – where batteries, magnets, solar equipment, transformers and other technologies are produced.

Technology-control geography – where intellectual property, industrial know-how and strategic manufacturing capacity are concentrated.

This creates a new form of geopolitical dependency.

For example, a country may possess substantial lithium deposits but still depend on foreign countries for refining, cathode production, battery cells or associated technologies.

The IEA has highlighted the concentration of processing capacity as a major vulnerability. Its 2025 assessment found particularly strong concentration in materials such as lithium, cobalt, graphite and rare-earth-related supply chains. (IEA)

3. Why Electricity Technology Materials Are Geopolitically Important

A. Electrification increases mineral dependence

The transition from fossil-fuel-based systems toward electrification increases demand for materials.

They are required for:

The IEA reported that battery demand alone increased substantially in 2025, while electricity infrastructure and renewable deployment continued to drive demand for critical minerals. (IEA)

4. Resource Concentration and Geopolitical Power

The first geopolitical problem is geographical concentration.

A small number of countries may control substantial portions of:

mining;

refining;

chemical conversion;

component manufacturing;

battery-cell production;

permanent-magnet production; and

specialised processing technologies.

This produces what can be called strategic chokepoints.

A disruption at a chokepoint can affect the entire electricity technology chain.

For example:

Mine → concentrate → chemical processing → refined material → component → technology → electricity infrastructure

A country does not necessarily need to control the mine to possess geopolitical influence. Control over refining or intermediate processing can be equally important.

5. China and Electricity Technology Supply Chains

China occupies an important position in several electricity-technology supply chains, particularly in mineral processing and battery manufacturing.

The IEA has identified China as a dominant processor of several strategic minerals and a major participant in battery supply chains. It has also noted that China accounts for very high shares of certain refined materials and battery manufacturing capacity. (IEA)

This creates an important distinction between:

resource ownership and industrial supply-chain control.

A country may have natural resources but lack:

refining facilities;

chemical processing capacity;

skilled labour;

manufacturing ecosystems;

technology;

financing;

infrastructure.

Consequently, geopolitical competition increasingly concerns the entire value chain, rather than simply mineral deposits.

6. Rare Earths and Electricity Technologies

Rare-earth elements are particularly significant for technologies using permanent magnets.

They are important in:

high-performance electric motors;

wind turbines;

generators;

defence-related systems;

advanced electronics.

The geopolitical significance of rare earths became particularly clear through the WTO dispute involving China's export restrictions.

7. Case Law: China — Rare Earths, Tungsten and Molybdenum

China — Measures Related to the Exportation of Rare Earths, Tungsten and Molybdenum

WTO Disputes DS431, DS432 and DS433

This is one of the most important international legal cases concerning the geopolitics of strategic minerals.

The United States, European Union and Japan challenged Chinese measures involving export duties, export quotas and restrictions on trading rights relating to rare earths, tungsten and molybdenum. (World Trade Organization)

China argued, among other things, that its measures were connected with the conservation of exhaustible natural resources and environmental concerns.

Legal issue

The central question was whether China's export restrictions could be justified under Article XX(g) of GATT 1994, concerning conservation of exhaustible natural resources.

The WTO proceedings recognised that states possess sovereignty over natural resources and can pursue legitimate conservation policies. However, the measures must satisfy the applicable WTO requirements.

The WTO findings concluded that the challenged export quotas were not justified under Article XX(g), particularly because they were not applied in an appropriately even-handed manner and were found to support industrial-policy objectives. (World Trade Organization)

China subsequently removed the export duties, quotas and certain trading-right restrictions that had been found inconsistent with WTO obligations. (World Trade Organization)

Legal significance

The case establishes an important principle:

Control over strategically important natural resources does not automatically permit a state to impose discriminatory or WTO-inconsistent export restrictions.

For electricity technology materials, this is highly significant because governments may have legitimate environmental, conservation and resource-security objectives while simultaneously possessing incentives to favour domestic manufacturers.

8. Nickel and Battery Geopolitics: Indonesia — Raw Materials

Another important dispute is:

Indonesia — Measures Relating to Raw Materials

WTO DS592

The European Union challenged Indonesian measures concerning nickel, including an export prohibition and domestic-processing requirements.

The dispute concerned Indonesia's policy of encouraging domestic processing rather than exporting raw nickel ore. (World Trade Organization)

The geopolitical significance is considerable because nickel is important to several battery technologies.

The dispute illustrates the concept of resource nationalism.

A resource-rich state may attempt to move from:

Raw-material exporter → processed-material exporter → battery-material producer → battery manufacturer

This can increase domestic industrial capacity and capture more value from natural resources.

However, such policies can conflict with international trade obligations.

9. Resource Nationalism

Resource nationalism occurs when governments adopt policies designed to increase national control over natural resources or capture a greater share of their economic value.

Common mechanisms include:

export restrictions;

export taxes;

domestic-processing requirements;

local-content requirements;

state ownership;

production quotas;

licensing restrictions;

strategic stockpiles;

foreign-investment restrictions.

For electricity technology materials, resource nationalism can be driven by two objectives:

Development objective

The state wants to develop domestic industries.

Security objective

The state wants to prevent strategic dependence on foreign supply chains.

The legal difficulty arises when domestic industrial policy conflicts with international trade commitments.

10. From Energy Security to Mineral Security

Traditional energy security generally focused on:

oil + gas + coal + electricity supply.

Modern energy security increasingly includes:

critical minerals + processing + manufacturing + technology + recycling.

The IEA has described critical-mineral concentration as an increasingly important energy-security risk. Its 2025 World Energy Outlook noted that one country was the dominant refiner for 19 of 20 energy-related strategic minerals examined, with an average market share of around 70%. (IEA)

Thus, electricity security can be disrupted before electricity generation begins.

For example:

Mineral shortage → battery manufacturing disruption → storage shortage → grid flexibility constraint → electricity-system vulnerability.

11. Copper and Grid Geopolitics

Copper is particularly important because electricity grids require enormous quantities of conductive material.

It is used in:

transmission lines;

distribution networks;

transformers;

motors;

generators;

renewable-energy equipment;

EV charging infrastructure.

The IEA has specifically identified rapid growth in copper demand associated with grid investment. (IEA)

This creates a different geopolitical problem from lithium or cobalt.

Copper is not merely a battery material. It is fundamental to electrification itself.

Therefore, inadequate copper supply can constrain:

grid expansion;

renewable integration;

electrification;

charging infrastructure;

industrial decarbonisation.

12. Battery Materials and Strategic Dependence

Battery supply chains demonstrate how geopolitics operates across multiple stages.

For example:

Lithium mine

↓

Chemical conversion

↓

Cathode/anode materials

↓

Battery cells

↓

Battery packs

↓

Electricity storage

The country controlling only one stage may still be strategically dependent on another country.

This is why modern industrial policy increasingly focuses on supply-chain resilience rather than simple domestic extraction.

13. Technology Substitution as a Geopolitical Strategy

An important legal and policy response is technological diversification.

For example, battery chemistry can affect mineral dependence.

The IEA has identified the development of alternative battery chemistries as one potential means of reducing upstream vulnerabilities, although downstream manufacturing can remain geographically concentrated. (IEA)

Therefore:

Technological innovation → reduced dependence on particular materials → reduced geopolitical vulnerability.

But substitution can create new dependencies.

For example, reducing dependence on one mineral may increase dependence on another.

14. Recycling as a Geopolitical Instrument

Recycling can reduce dependence on primary extraction.

A circular-material system can be represented as:

Mining → Manufacturing → Electricity Technology → Use → Collection → Recycling → Recovered Materials → Manufacturing

Recycling therefore becomes an element of energy security law.

Governments may introduce:

recycling obligations;

producer-responsibility schemes;

battery collection requirements;

minimum recycled-content standards;

material-recovery targets;

strategic recycling infrastructure.

These measures can transform waste regulation into an element of geopolitical strategy.

15. Strategic Stockpiling

States can also create strategic reserves of critical materials.

A strategic stockpile can provide protection against:

war;

sanctions;

export restrictions;

trade disputes;

natural disasters;

mining disruptions;

transportation interruptions.

The legal framework may regulate:

who owns the stockpile;

when materials can be released;

who can purchase them;

emergency-release criteria;

financing;

reporting requirements.

Strategic stockpiling therefore links public law, national security law, trade law and energy law.

16. Critical-Mineral Legislation

Modern jurisdictions are increasingly developing legal frameworks for critical materials.

The European Union's Critical Raw Materials framework, for example, seeks to strengthen extraction, processing, recycling and diversification of critical-material supply chains.

Such legislation reflects a movement away from relying exclusively on international markets toward a resilience-oriented regulatory model.

This creates potential legal questions concerning:

WTO compatibility;

non-discrimination;

subsidies;

public procurement;

investment screening;

environmental permitting;

state aid;

strategic partnerships.

17. Geopolitical Competition and International Trade Law

The geopolitics of electricity materials frequently creates tension between two principles:

Principle 1: Resource sovereignty

States have legitimate authority to regulate their natural resources and environmental impacts.

Principle 2: Open international trade

States must respect international trade obligations.

The China Rare Earths case demonstrates that resource sovereignty does not necessarily provide an unlimited legal defence for export restrictions. (World Trade Organization)

The Indonesia nickel dispute demonstrates another dimension: domestic-processing strategies may generate international trade litigation. (World Trade Organization)

18. Subsidies and Industrial Policy

Governments increasingly provide support for domestic:

battery factories;

semiconductor manufacturing;

solar manufacturing;

mineral processing;

grid equipment;

critical-mineral projects.

These policies can include:

tax credits;

grants;

concessional finance;

loan guarantees;

government procurement;

production incentives.

The geopolitical purpose is often to create domestic or allied supply chains.

However, subsidies can produce international legal disputes where they distort competition or conflict with WTO obligations.

19. National Security and Foreign Investment

Critical-material industries are increasingly treated as strategic infrastructure.

Governments may therefore scrutinise foreign investment in:

mines;

mineral-processing plants;

battery manufacturers;

semiconductor companies;

grid-equipment manufacturers;

rare-earth facilities.

Investment-screening legislation may be justified on grounds of:

national security;

critical infrastructure;

technological sovereignty;

economic security.

This represents an expansion of the traditional concept of national security into economic and technological security.

20. Electricity Technology Materials and Sanctions

Geopolitical conflicts can also restrict access to materials through:

sanctions;

export controls;

financial restrictions;

shipping restrictions;

technology controls.

Unlike an ordinary commercial disruption, sanctions can deliberately prevent a country from obtaining strategic materials or technologies.

The resulting legal questions include:

What international obligations apply?

Is the restriction discriminatory?

Does a national-security exception apply?

Is the measure proportionate or otherwise legally defensible?

What happens to existing contracts?

Can affected companies obtain compensation?

21. Environmental Justice Dimension

Critical-mineral geopolitics also has an environmental dimension.

Mining can generate:

land degradation;

water consumption;

pollution;

biodiversity loss;

displacement;

labour concerns.

Therefore, electricity-transition law must avoid simply transferring environmental costs from developed electricity markets to resource-producing states.

A legally sustainable system should integrate:

energy security + trade law + environmental law + human rights + development law.

22. India and the Geopolitics of Electricity Materials

For India, the issue is particularly important because rapid electrification requires:

transmission expansion;

renewable-energy equipment;

batteries;

EV infrastructure;

power electronics;

transformers;

solar manufacturing.

India's strategic approach can therefore involve:

diversification of mineral imports;

domestic exploration;

overseas mineral partnerships;

recycling;

domestic processing;

battery manufacturing;

strategic stockpiling;

alternative technologies.

The legal framework must coordinate mining law, electricity law, environmental law, industrial policy, customs law and international trade law.

23. Emerging Legal Doctrine

The geopolitics of electricity technology materials is contributing to an emerging legal concept that may be described as material-energy security law.

Its central idea is:

Electricity security depends not only upon generating and transmitting electricity, but also upon securing the physical materials and technologies necessary to construct and maintain electricity systems.

This expands traditional energy law.

Previously:

Energy law → regulation of energy production and consumption

Increasingly:

Energy law → production + networks + technologies + minerals + supply chains + recycling + geopolitical resilience

24. Key Case Laws

The first two are particularly directly connected to critical-material geopolitics.

25. Future Legal Challenges

Several major legal questions are likely to become increasingly important.

1. Can states restrict critical-mineral exports?

Yes, potentially, but restrictions must be assessed against applicable international obligations and exceptions.

2. Can governments require domestic processing?

They may pursue industrial-development policies, but such requirements can create WTO disputes, as illustrated by the Indonesia nickel dispute.

3. Can states subsidise domestic battery and mineral industries?

Yes, subject to applicable subsidy and trade rules.

4. Can national-security exceptions protect strategic-material restrictions?

Potentially, but the precise scope of national-security exceptions remains legally significant.

5. Can environmental concerns justify mineral restrictions?

Environmental and conservation objectives can be legally relevant, but the design and application of the measure matter.

26. Conclusion

The geopolitics of electricity technology materials represents a fundamental transformation in energy security.

The energy system is moving from dependence primarily on:

oil + gas + coal

toward increasing dependence on:

copper + lithium + nickel + cobalt + graphite + manganese + rare earths + advanced manufacturing capacity.

The geopolitical struggle therefore increasingly concerns who mines, who processes, who manufactures, who controls technology and who has access to strategic supply chains.

The WTO's China–Rare Earths litigation demonstrates that strategic control over minerals is constrained by international trade law, while Indonesia–Raw Materials illustrates the legal tensions surrounding domestic processing and resource nationalism. (World Trade Organization)

The emerging legal architecture will therefore have to balance four objectives:

resource sovereignty + international trade + electricity security + environmental sustainability.

The central lesson is that electricity security is becoming inseparable from material security. A resilient electricity transition consequently requires not merely more generation and transmission infrastructure, but diversified mineral supplies, processing capacity, recycling systems, technological alternatives and legally stable international supply chains.
