Records for renewable energy consumption were smashed around the world in 2017.

Looking at national and state grids, progress has been extremely impressive. In Costa Rica, for example, renewable energy supplied five million people with all of their electricity needs for a stretch of 300 consecutive days. Meanwhile, the U.K. broke 13 green energy records in 2017 alone, and California’s largest grid operator announced it got 67.2% of its energy from renewables (excluding hydro) on May 13, 2017.

The corporate front is also looking promising, and Google has led the way by buying 536 MW of wind power to offset 100% of the company’s electricity usage. This makes the tech giant the biggest corporate purchaser of renewable energy on the planet.

But while these examples are plentiful, this progress is only the tip of the iceberg – and green energy still represents a small but rapidly growing segment. For a full green shift to occur, we’ll need to 10x what we’re currently sourcing from renewables.

To do this, we will need to procure massive amounts of natural resources – they just won’t be the fossil fuels that we’re used to.

Green Metals Required

Today’s infographic comes from Cambridge House as a part of the lead-up to their flagship conference, the Vancouver Resource Investment Conference 2018.

A major theme of the conference is sustainable energy – and the math indeed makes it clear that to fully transition to a green economy, we’ll need vast amounts of metals like copper, silicon, aluminum, lithium, cobalt, rare earths, and silver.

These metals and minerals are needed to generate, store, and distribute green energy. Without them, the reality is that technologies like solar panels, wind turbines, lithium-ion batteries, nuclear reactors, and electric vehicles are simply not possible.

First Principles

How do you get a Tesla to drive over 300 miles (480 km) on just one charge?

Here’s what you need: a lightweight body, a powerful electric motor, a cutting-edge battery that can store energy efficiently, and a lot of engineering prowess.

Putting the engineering aside, all of these things need special metals to work. For the lightweight body, aluminum is being substituted in for steel. For the electric motor, Tesla is using AC induction motors (Model S and X) that require large amounts of copper and aluminum. Meanwhile, Chevy Bolts and soon Tesla will use permanent magnet motors (in the Model 3) that use rare earths like neodymium, dysprosium, and praseodymium.

The batteries, as we’ve shown in our five-part Battery Series, are a whole other supply chain challenge. The lithium-ion batteries used in EVs need lithium, nickel, cobalt, graphite, and many other metals or minerals to function. Each Tesla battery, by the way, weighs about 1,200 lbs (540 kg) and makes up 25% the total mass of the car.

While EVs are a topic we’ve studied in depth, the same principles apply for solar panels, wind turbines, nuclear reactors, grid-scale energy storage solutions, or anything else we need to secure a sustainable future. Solar panels need silicon and silver, while wind turbines need rare earths, steel, and aluminum.

Even nuclear, which is the safest energy type by deaths per TWh and generates barely any emissions, needs uranium in order to generate power.

The Pace of Progress

The green revolution is happening at a breakneck speed – and new records will continue to be set each year.

Over $200 billion was invested into renewables in 2016, and more net renewable capacity was added than coal and gas put together:

Power TypeNet Global Capacity Added (2016)
Renewable (excl. large hydro)138 GW
Coal54 GW
Gas37 GW
Large hydro15 GW
Nuclear10 GW
Other flexible capacity5 GW

The numbers suggest that this is the only start of the green revolution.

However, to fully work our way off of fossil fuels, we will need to procure large amounts of the metals that make sustainable energy possible.

Visualizing China’s Cobalt Supply Dominance by 2030

Chinese dominance over critical minerals used in technologies like smartphones, electric vehicles (EVs), and solar power has become a growing concern for the U.S. and other Western countries.

Currently, China refines 68% of the world’s nickel, 40% of copper, 59% of lithium, and 73% of cobalt, and is continuing to expand its mining operations.

This graphic visualizes the total cobalt supply from the top 10 producers in 2030, highlighting China’s dominance. The data comes from Benchmark Mineral Intelligence, as of July 2024.

China’s Footprint in Africa

Cobalt is a critical mineral with a wide range of commercial, industrial, and military applications. It has gained significant attention in recent years due to its use in battery production. Today, the EV sector accounts for 40% of the global cobalt market.

The Democratic Republic of Congo (DRC) currently produces 74% of the world’s cobalt supply. Although cobalt deposits exist in regions like Australia, Europe, and Asia, the DRC holds the largest reserves by far.

China is the world’s leading consumer of cobalt, with nearly 87% of its cobalt consumption dedicated to the lithium-ion battery industry.

Although Chinese companies hold stakes in only three of the top 10 cobalt-producing countries, they control over half of the cobalt production in the DRC and Indonesia, and 85% of the output in Papua New Guinea.

Given the DRC’s large share of global cobalt production, many Chinese companies have expanded their presence in the country, acquiring projects and forming partnerships with the Congolese government.

According to Benchmark, Chinese companies are expected to control 46% of the global cobalt mined supply by 2030, a 3% increase from 2023.

By 2030, the top 10 cobalt-producing countries will account for 96% of the total mined supply, with just two countries—the DRC and Indonesia—contributing 84% of the total.

The total copper per vehicle is projected to decrease by 38 kg between 2015 and 2030.

Visualizing the Decline of Copper Usage in EVs

Copper intensity in passenger battery electric vehicles (BEVs) has steadily decreased over the last decade, driven by numerous technological advancements alongside increasing usage of alternative materials such as aluminum.

In this graphic, we visualize the evolution of copper demand in various subcomponents of passenger battery electric vehicles (BEVs) from 2015 to 2030F, along with total global copper demand driven by EVs for the same period. This data comes exclusively from Benchmark Mineral Intelligence.

Copper Intensity Per Car

According to Benchmark Mineral Intelligence, the copper intensity per vehicle is expected to decline by almost 38 kg, from 99 kg in 2015 to 62 kg by 2030.

2030F17825.635.442.373.2661.70

One of the most significant factors driving this decline is thrifting, where engineers and manufacturers continuously improve the efficiency and performance of various components, leading to reduced copper usage. A key example of this is in battery production, where the thickness of copper foil used in battery anodes has significantly decreased.

In 2015, Benchmark estimated copper foil usage was just over 41 kg per vehicle (at an average thickness of 10 microns), but by 2030, it is projected to fall to 26 kg as manufacturers continue to adopt thinner foils.

Similarly, automotive wiring systems have become more localized, with advances in high-voltage wiring and modular integration allowing for reduced copper content in wiring harnesses.

Copper used in wiring has dropped from 30 kg per vehicle in 2015 to a projected 17 kg by 2030.

Newer, more compact power electronics and improved thermal management in motors and charging cables have also contributed to the reduction in copper usage.

Substitution has also played a role, with alternatives such as aluminum increasingly being used in components like busbars, wiring harnesses, and charging cable applications.

Aluminum’s lighter weight and lower cost have made it a practical alternative to copper in specific applications, though the additional space required to achieve the same level of conductivity can limit its use in certain cases.

Benchmark estimates that copper used in automotive wire harnesses has declined by 30% between 2015 and 2024.

The Road Ahead

Despite reductions in per-vehicle copper usage, the outlook for copper demand from the EV sector remains strong due to the sector’s growth.

2030F2.5M

Benchmark’s analysis indicates that by 2030, copper demand driven by EVs alone will exceed 2.5 million tonnes, securing copper’s critical role in the transition to a low-carbon future.
