Silver in Electronics, Medicine, and EVs: The Industrial Demand Story
Silver's investment case is inseparable from its industrial uses. Unlike gold — where industrial use accounts for less than 10% of annual demand — silver derives roughly 55–60% of its total demand from industrial applications. This creates a fundamentally different demand profile and ties silver's fortunes to the health of the global economy and, increasingly, to the energy transition.
Electronics: The Foundation of Industrial Demand
Silver's primary industrial use is in electrical and electronic applications. It has the highest electrical conductivity of any element, making it the preferred contact material for switches, relays, and circuit boards where resistance losses must be minimised.
Virtually every smartphone, laptop, EV, and home appliance contains silver. As global electronics production has grown and products have become more sophisticated, the silver content per device — while declining on a per-unit basis due to thrifting — has been more than offset by unit volume growth.
Solar Photovoltaics: The Fastest-Growing Use Case
The rise of solar energy is the single most important new driver of silver industrial demand in the 21st century. Silver paste is printed onto silicon wafers to form the electrical contacts that collect the current generated by sunlight.
Solar now accounts for approximately 14–15% of total annual silver demand, up from less than 5% a decade ago. Under the International Energy Agency's net-zero scenario, solar installations must grow roughly five-fold by 2050 — implying a structural demand tailwind that mining supply is unlikely to meet without significant price incentives.
Electric Vehicles
Each electric vehicle contains approximately 25–50 grams of silver — roughly twice the silver content of a conventional internal combustion engine vehicle. Silver is used in battery management systems, charging infrastructure, and various electronic control units.
As global EV penetration rises from today's roughly 15% of new car sales toward projected 50%+ by 2035 in major markets, automotive silver demand is set to grow substantially.
Medicine and Antimicrobial Applications
Silver has been recognised for its antimicrobial properties since antiquity. In modern medicine, it appears in wound dressings, surgical instruments, catheters, and coatings for hospital surfaces where infection control is critical. Silver nanoparticles are also used in water purification systems and air filtration.
Medical silver demand, while smaller than electronics or solar, is growing steadily and is essentially recession-proof — hospitals do not cut infection control budgets in downturns.
The Investment Implication
Industrial demand provides a demand floor for silver that gold does not have. Even in a bearish macroeconomic environment where investment demand fades, silver's structural industrial bid — particularly from solar and EVs — limits the downside and provides a fundamentally different risk-reward profile from gold.
