It’s no secret that Elon Musk is known for bold, revolutionary ideas.
And by many measures, he’s been extraordinarily successful. Tesla recorded a near‑record 97,000 global vehicle orders in the third quarter, and received roughly 250,000 preorders for the Cybertruck. The company’s stock more than doubled since May 1, and Tesla vehicles have drawn praise from many industry observers.
But there’s an aspect of the green transition that rarely gets attention from prominent CEOs, including Musk.
They all depend on a critical industrial metal: silver.
Silver’s unique chemical and physical properties make it an essential component in many clean technologies. As society adopts more renewable energy systems, electric vehicles, and advanced electronics, demand for silver increases—often behind the scenes.
Below are the main ways silver supports the green revolution.
Electricity Generation
Silver is widely used in electrical generation because it has the highest known electrical and thermal conductivity of all metals. Solar power, one of the fastest-growing renewable sources, relies on silver in photovoltaic (PV) cells. On average, a typical solar panel contains roughly 20 grams of silver—about two‑thirds of an ounce.
For example, installing 23 solar panels on a home would use around 14.8 ounces of silver. That may seem modest per installation, but as solar adoption scales across homes, businesses, and utilities, these ounces add up quickly.
New regulations and broader adoption are driving growth. Some regions are already requiring solar on new low‑rise buildings, and many countries, including China and India, are expanding solar capacity rapidly because it’s cost‑competitive and quick to deploy.
It’s also not just solar: wind energy uses silver as well. Silver‑containing brushes and electrical contacts are employed in turbine motors and generators. While copper alternatives exist, silver parts often deliver better long‑term performance despite higher upfront cost.
Industry forecasts project substantial expansion of renewables: by 2030 renewables could account for a much larger share of power generation, prompting significantly more silver demand.
- By 2050, solar panels and wind turbines are estimated to require roughly three times more silver than they do today.
Because silver’s conductivity is difficult to match, manufacturers face limits on how much silver content they can reduce before sacrificing efficiency and performance. That physical constraint keeps silver integral to many PV technologies.
Electric and Hybrid Vehicles
Electric vehicles (EVs), battery‑electric vehicles (BEVs), and plug‑in hybrids (PHEVs) use more silver than traditional internal combustion engine vehicles. Silver is used in electric motors, battery management systems, and electrical contacts throughout the vehicle.
Although the silver content per EV is relatively small, rapid fleet electrification multiplies the total demand. Electrification also extends to conventional vehicles: many cars now incorporate silver‑coated contacts for switches, seat heaters, window controls, and electronic displays.
As automakers increase the electrification of features and as EV market share grows, silver demand from the automotive sector is expected to rise materially.
- Analysts estimate that automotive silver usage could reach about 70 million ounces by 2030, up from roughly 45 million ounces in 2017.
Nuclear Energy
Nuclear power is a low‑emission source of electricity and also uses silver in critical components. Silver alloys and silver‑bearing materials are used in certain control rods and specialized components within reactors. While each reactor uses a modest amount, the aggregate use across the industry is meaningful.
Newer reactor designs and expanding nuclear capacity can increase silver demand from this sector as well. Replacement rates may be low, but building additional reactors adds to total consumption.
- The silver used in nuclear control rods is relatively small per unit but essential to reactor function, and total demand will grow with industry expansion.
Going Green = Going Silver
As the world adopts more renewable energy, electrified transportation, and advanced energy systems, silver becomes increasingly woven into daily life. Its exceptional conductive and thermal properties make it difficult to replace in many high‑performance applications.
Whether powering a rooftop solar array, driving an electric vehicle, or operating a modern appliance, people benefit from technologies that rely on silver—often without realizing it.
As new clean technologies emerge, silver’s role is likely to remain significant, ensuring it stays an important material in the transition to a lower‑carbon economy.
The growing demand from green technologies could further tighten global silver supply. Industry observers expect this trend to create both challenges and opportunities in the metals market.
