Silver Through the Ages: The Uses of Silver Over Time

Published

on

The following content is sponsored by Blackrock Silver.

Silver is one of the most versatile metals on Earth, with a unique combination of uses both as a precious and industrial metal.

Today, silver’s uses span many modern technologies, including solar panels, electric vehicles, and 5G devices. However, the uses of silver in currency, medicine, art, and jewelry have helped advance civilization, trade, and technology for thousands of years.

The Uses of Silver Over Time

The below infographic from Blackrock Silver takes us on a journey of silver’s uses through time, from the past to the future.

3,000 BC – The Middle Ages

The earliest accounts of silver can be traced to 3,000 BC in modern-day Turkey, where its mining spurred trade in the ancient Aegean and Mediterranean seas. Traders and merchants would use hacksilver—rough-cut pieces of silver—as a medium of exchange for goods and services.

Around 1,200 BC, the Ancient Greeks began refining and minting silver coins from the rich deposits found in the mines of Laurion just outside Athens. By 100 BC, modern-day Spain became the center of silver mining for the Roman Empire while silver bullion traveled along the Asian spice trade routes. By the late 1400s, Spain brought its affinity for silver to the New World where it uncovered the largest deposits of silver in history in the dusty hills of Bolivia.

Besides the uses of silver in commerce, people also recognized silver’s ability to fight bacteria. For instance, wine and food containers were often made out of silver to prevent spoilage. In addition, during breakouts of the Bubonic plague in medieval and renaissance Europe, people ate and drank with silver utensils to protect themselves from disease.

The 1800s – 2000s

New medicinal uses of silver came to light in the 19th and 20th centuries. Surgeons stitched post-operative wounds with silver sutures to reduce inflammation. In the early 1900s, doctors prescribed silver nitrate eyedrops to prevent conjunctivitis in newborn babies. Furthermore, in the 1960s, NASA developed a water purifier that dispensed silver ions to kill bacteria and purify water on its spacecraft.

The Industrial Revolution drove the onset of silver’s industrial applications. Thanks to its high light sensitivity and reflectivity, it became a key ingredient in photographic films, windows, and mirrors. Even today, skyscraper windows are often coated with silver to reflect sunlight and keep interior spaces cool.

The 2000s – Present

The uses of silver have come a long way since hacksilver and utensils, evolving with time and technology.

Silver is the most electrically conductive metal, making it a natural choice for electronic devices. Almost every electronic device with a switch or button contains silver, from smartphones to electric vehicles. Solar panels also utilize silver as a conductive layer in photovoltaic cells to transport and store electricity efficiently.

In addition, it has several medicinal applications that range from treating burn wounds and ulcers to eliminating bacteria in air conditioning systems and clothes.

Silver for the Future

Silver has always been useful to industries and technologies due to its unique properties, from its antibacterial nature to high electrical conductivity. Today, silver is critical for the next generation of renewable energy technologies.

For every age, silver proves its value.

An Introduction to MSCI ESG Indexes

With an extensive suite of ESG indexes on offer, MSCI aims to support investors as they build a more personalized and resilient portfolio.

An Introduction to MSCI ESG Indexes

There are various portfolio objectives within the realm of sustainable investing.

For example, some investors may want to build a portfolio that reflects their personal values. Others may see environmental, social, and governance (ESG) criteria as a tool for improving long-term returns, or as a way to create positive impact. A combination of all three of these motivations is also possible.

To support investors as they embark on their sustainable journey, our sponsor, MSCI, offers over 1,500 purpose-built ESG indexes. In this infographic, we’ll take a holistic view at what these indexes are designed to achieve.

An Extensive Suite of ESG & Climate Indexes

Below, we’ll summarize the four overarching objectives that MSCI’s ESG & climate indexes are designed to support.

Objective 1: Integrate a broad set of ESG issues

Investors with this objective believe that incorporating ESG criteria can improve their long-term risk-adjusted returns.

The MSCI ESG Leaders indexes are designed to support these investors by targeting companies that have the highest ESG-rated performance from each sector of the parent index.

For those who do not wish to deviate from the parent index, the MSCI ESG Universal indexes may be better suited. This family of indexes will adjust weights according to ESG performance to maintain the broadest possible universe.

Objective 2: Generate social or environmental benefits

A common challenge that impact investors face is measuring their non-financial results.

Consider an asset owner who wishes to support gender diversity through their portfolios. In order to gauge their success, they would need to regularly filter the entire investment universe for updates regarding corporate diversity and related initiatives.

In this scenario, linking their portfolios to an MSCI Women’s Leadership Index would negate much of this groundwork. Relative to a parent index, these indexes aim to include companies which lead their respective countries in terms of female representation.

Objective 3: Exclude controversial activities

Many institutional investors have mandates that require them to avoid certain sectors or industries. For example, approximately $14.6 trillion in institutional capital is in the process of divesting from fossil fuels.

To support these efforts, MSCI offers indexes that either:

  • Exclude individual sectors such as fossil fuels, tobacco, or weapons;
  • Exclude companies from a combination of these sectors; or
  • Exclude companies that are not compatible with certain religious values.

Objective 4: Identify climate risks and opportunities

Climate change poses a number of wide-reaching risks and opportunities for investors, making it difficult to tailor a portfolio accordingly.

With MSCI’s climate indexes, asset owners gain the tools they need to build a more resilient portfolio. The MSCI Climate Change indexes, for example, reduce exposure to stranded assets, increase exposure to solution providers, and target a minimum 30% reduction in emissions.

An Index for Every Objective

Regardless of your motivation for pursuing sustainable investment, the need for an appropriate benchmark is something that everyone shares.

With an extensive suite of ESG indexes designed specifically for sustainability and climate change, MSCI aims to support asset owners as they build a more unique and personalized portfolio.

Tracked: The U.S. Utilities ESG Report Card

As emissions reductions and sustainable practices become more important for electrical utilities, environmental, social, and governance (ESG) reporting is coming under increased scrutiny.

Once seen as optional by most companies, ESG reports and sustainability plans have become commonplace in the power industry. In addition to reporting what’s needed by regulatory state laws, many utilities utilize reporting frameworks like the Edison Electric Institute’s (EEI) ESG Initiative or the Global Reporting Initiative (GRI) Standards.

But inconsistent regulations, mixed definitions, and perceived importance levels have led some utilities to report significantly more environmental metrics than others.

How do U.S. utilities’ ESG reports stack up? This infographic from the National Public Utilities Council tracks the ESG metrics reported by 50 different U.S. based investor-owned utilities (IOUs).

What’s Consistent Across ESG Reports

To complete the assessment of U.S. utilities, ESG reports, sustainability plans, and company websites were examined. A metric was considered tracked if it had concrete numbers provided, so vague wording or non-detailed projections weren’t included.

Of the 50 IOU parent companies analyzed, 46 have headquarters in the U.S. while four are foreign-owned, but all are regulated by the states in which they operate.

For a few of the most agreed-upon and regulated measures, U.S. utilities tracked them almost across the board. These included direct scope 1 emissions from generated electricity, the utility’s current fuel mix, and water and waste treatment.

Another commonly reported metric was scope 2 emissions, which include electricity emissions purchased by the utility companies for company consumption. However, a majority of the reporting utilities labeled all purchased electricity emissions as scope 2, even though purchased electricity for downstream consumers are traditionally considered scope 3 or value-chain emissions:

  • Scope 1: Direct (owned) emissions.
  • Scope 2: Indirect electricity emissions from internal electricity consumption. Includes purchased power for internal company usage (heat, electrical).
  • Scope 3: Indirect value-chain emissions, including purchased goods/services (including electricity for non-internal use), business travel, and waste.

ESG Inconsistencies, Confusion, and Unimportance

Even putting aside mixed definitions and labeling, there were many inconsistencies and question marks arising from utility ESG reports.

For example, some utilities reported scope 3 emissions as business travel only, without including other value chain emissions. Others included future energy mixes that weren’t separated by fuel and instead grouped into “renewable” and “non-renewable.”

The biggest discrepancies, however, were between what each utility is required to report, as well as what they choose to. That means that metrics like internal energy consumption didn’t need to be reported by the vast majority.

Likewise, some companies didn’t need to report waste generation or emissions because of “minimal hazardous waste generation” that fell under a certain threshold. Other metrics like internal vehicle electrification were only checked if the company decided to make a detailed commitment and unveil its plans.

As pressure for the electricity sector to decarbonize continues to increase at the federal level, however, many of these inconsistencies are roadblocks to clear and direct measurements and reduction strategies.
