Why Copper Is Critical for Data Centers

Data centers are computer server hubs that collect, store, and process large amounts of data, requiring extensive network infrastructure and electric power supply.

As the North American data center market grows, copper will be a key building block in this infrastructure.

This infographic from the Copper Development Association illustrates the critical role of copper in data center development.

Copper in Technology

Much has been said about the growing demand for critical minerals like copper, nickel, and lithium for clean technologies such as batteries, EVs, solar, and wind power.

Copper, however, has a more extensive role in technology as it is used in wires that connect power grids and data centers around the planet.

As one of the best conductors of electricity, copper maximizes efficiency in the transmission and distribution of electricity. Its thermal conductivity also helps build efficient heat exchangers, which are vital for cooling in data centers.

The inherent ductility and malleability of copper make it ideal for shaping into compact system components, like electrical connectors. In addition, copper can be fully recycled without losing any beneficial properties, providing an excellent solution in a growing green economy.

Data centers use copper across various electrical applications, including:

  • Power cables
  • Busbars
  • Electrical connectors
  • Heat exchangers and sinks
  • Power distribution strips

To put the demand into perspective, Microsoft’s $500 million data center in Chicago required 2,177 tonnes of copper for construction.

North America’s Growing Need for Copper

With the rise of cloud computing and the Internet of Things (IoT), the North American data center market is expanding.

North American data center infrastructure is expected to grow from a $33 billion business in 2020 to $70 billion in 2030 and $185 billion in 2040.

This, in turn, will amplify the demand for copper. Copper consumption for data centers is estimated to jump from 197,000 tonnes in 2020 to 238,000 tonnes in 2030 and 293,000 tonnes in 2040.

The Copper Development Association (CDA) brings the value of copper and its alloys to society to address the challenges of today and tomorrow. Visit www.copper.org to learn more about copper’s critical role in data centers.

Charted: The End-of-Life Recycling Rates of Select Metals

End-of-life recycling rates measure the percentage of a material that is recovered at the end of its useful life, rather than being disposed of or incinerated.

A chart ranking the end-of-life recycling rates (EOL-RR) of commonly used metals in the economy, per 2021 data from the International Energy Agency.

We visualize the end-of-life recycling rates (EOL-RR) of commonly used metals in the economy. Data is sourced from the International Energy Agency, last updated in 2021.

ℹ️ EOL-RR is the percentage of a material or product that is recycled or recovered at the end of its useful life, rather than being disposed of in landfills or incinerated.

Tracking recycling rates helps manage resources better and make smarter policies, guiding efforts to cut down on waste.

Ranked: The End of Life Recycling Rates of Select Metals

Gold has an 86% recycling rate according to the latest available data. Per the Boston Consulting Group, one-third of total gold supply was met through recycling between 1995–2014.

Note: Figures are rounded.

Several factors can influence metal recycling rates. According to this International Resource Panel report, metals that are used in large quantities (steel) or have a high value (gold) tend to have higher recycling rates.

However, for materials used in small quantities in complex products (rare earth elements in electronics), recycling becomes far more challenging.

Finally, a metal’s EOL-RR is strongly influenced by the least efficient link in the recycling chain, which is typically how it’s initially collected.

Companies with the Most Fossil Fuel and Cement CO2 Emissions

Half of the world’s total fossil fuel and cement carbon dioxide emissions in 2023 came from just 36 companies.

Half of the world’s carbon dioxide emissions in 2023 came from just 36 companies. Here, we chart the world's biggest polluters.

Companies with the Most Fossil Fuel and Cement CO2 Emissions

This was originally posted on our Voronoi app. Download the app for free on iOS or Android and discover incredible data-driven charts from a variety of trusted sources.

Key Takeaways

  • Half of the world’s fossil fuel and cement carbon dioxide emissions in 2023 came from just 36 entities, according to a report by the Carbon Majors Project
  • If Saudi Aramco were a country, it would be the fourth-largest polluter in the world, after China, the U.S., and India.
  • Five publicly traded oil companies—ExxonMobil, Chevron, Shell, TotalEnergies, and BP—together accounted for 5% of global carbon dioxide emissions from fossil fuels.

Chinese Companies Dominate the List

This graphic is based on Carbon Majors, a database of historical production data from 180 of the world’s largest oil, gas, coal, and cement producers representing 169 active and 11 inactive entities.

In 2023, the top 20 highest carbon-producing entities were responsible for 17.5 gigatonnes of carbon dioxide equivalent (GtCO₂e) in emissions, accounting for 40.8% of global fossil fuel and cement CO₂ emissions. The list is largely dominated by state-owned companies, with 16 of the top 20 being state-controlled. Notably, eight Chinese entities contributed to 17.3% of global fossil fuel and cement CO₂ emissions in 2023.
