A brief evolutionary history of silver
From coins and jewelry to EVs and solar panels, silver adapts Metal Tech News – April 7, 2021

Typically thought of as a glimmery precious metal used to make coins, bullion, jewelry, and other shiny objects, silver's true value lies in more industrious properties that make it invaluable to high-tech applications such as solar panels, electric vehicles, and 5G networks.
"Silver demand has evolved from a monetary ornamental use, to photographic, to digital, and now to energy," Hecla Mining Company President and CEO Phillips Baker, Jr. said during a March 31 keynote presentation at the Extractive Industry Investment Options Conference.
Hecla, which has been mining silver for 130 years, has been in the business long enough to witness first-hand silver's demand transition from coins and jewelry to solar panels and EVs.
In fact, the Idaho-based mining company traces its founding to a time when silver was losing its 4,000-year status as a choice metal for making coins and the rise of a revolutionary technology that would dictate silver demand for the entire 20th century – a camera for the masses.
Century of silver photography
In 1900, Eastman Kodak introduced the Brownie camera, an affordable camera that allowed everyday people to capture treasured moments and imagery for posterity.
"It was a very inexpensive camera when it first came out in 1900 – it sold for $1, which in today's dollars would be about $31," Baker said.
While the Brownie itself did not contain any silver, the film that images were captured on did. For the entirety of the 20th century, photography was a major consumer of silver. In 1999, roughly 250 million ounces of silver was used each year for photography.
When Baker joined Hecla in 2001, most silver analysts believed photography would continue to drive the demand for silver. The advent of the digital camera and then the smartphone, however, nearly completely ended the century-long era of silver-infused film. By 2019, photographic demand for silver had plummeted to just 34 million oz/year.
Despite this 86% drop in photographic demand, total silver consumption over the same period rose from 875 million oz/year to 1.07 billion oz/year. This is because of silver's rise as an investment metal and steady growth in industrial uses outside of photography.
The techno-metal era begins
The very technological advances that looked to tarnish silver demand have brightened the future for this shiny metal.
It is not silver's luster, however, that is driving the metal's technological demand. Instead, it is silver's status as the best metallic conductor of electricity that is propelling the metal into the future.
While less expensive copper is the most widely used metal for transporting electricity, when you want to build a powerful pocket computer, a little bit of silver goes a long way.
The same traits that make silver invaluable to your smartphone also make silver a vital ingredient for renewable energy and EVs.
Photovoltaic solar cells take advantage of both the high electrical and thermal conductivity traits offered by silver.
Approximately 0.7 oz of silver goes into the making of each photovoltaic solar panel. This currently accounts for roughly 90 million oz of silver demand per year, and Goldman Sachs projects this demand to climb to 105 million to 150 million oz by 2023.
"So, strong, strong demand growth for photovoltaics," said Baker.
The transition to electric mobility is pushing similar demand growth by the automotive sector.
This is because virtually every electrical connection in a modern car is activated with silver-coated contacts, and by their very nature, EVs have a lot more electrical connections.
While approximately 0.64 oz of silver goes into the average internal combustion engine vehicle, an EV needs about 1.25 oz of the techno-precious metal.
As a result, Bank of America forecasts the automotive sector will need about 90 million oz/year by 2026, a 64% increase over the roughly 55 million oz/year currently needed. And this demand is expected to continue to grow as EVs take over ICE vehicles for market domination.
Adding to the technological demands driven by solar and EVs, a recent report released by the silver institute forecasts that the global roll-out of 5G networks will require another 16 million oz/year by 2025 and as much as 23 million oz/year by 2030.
Global silver production currently sits at about 840 million oz/year and demand is approximately 1 billion oz/year. The roughly 170 million oz of silver recycled each year fills the difference between supply and demand. The emerging technological demands for silver, however, are expected to upset this balance.
Using very conservative estimates, the need for newly mined silver is forecast to increase by 95 million oz per year over the next decade.
This is nearly 10 times more than Hecla's Greens Creek Mine in Alaska, which singlehandedly accounted for roughly one-third of total U.S. silver production during 2020.
"Our largest mine, Greens Creek, produces 10 million oz of silver per year. By 2030 ... you would need 10 more Greens Creeks," said Baker.
The Hecla Mining CEO says it will likely take higher silver prices to spur the investments to build the silver mines needed to meet the emerging demands for this metal that continues to evolve with the times.
