The Raw Materials That Fuel the Green Revolution

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.
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 Type||Net Global Capacity Added (2016)|
|Renewable (excl. large hydro)||138 GW|
|Large hydro||15 GW|
|Other flexible capacity||5 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.
Ranked: The World’s Top Cobalt Producing Countries
Cobalt, an essential component for certain types of EV batteries, has seen a significant shift in its global production landscape.
Ranked: The World’s Top Cobalt Producing Countries
Cobalt, an essential component of key chemistries of the rechargeable lithium-ion batteries used in EVs, has seen a significant shift in its global production landscape.
The Democratic Republic of Congo (DRC) has long been the world’s largest cobalt producer, accounting for 73% of global output in 2022.
However, according to the Cobalt Institute, the DRC’s dominance is projected to decrease to 57% by 2030 as Indonesia ramps up its cobalt production as a byproduct from its rapidly expanding nickel industry.
Indonesia Became Second Largest Cobalt Producer in 2022
Indonesia accounts for nearly 5% of global cobalt production today, surpassing established producers like Australia and the Philippines.
In 2022, Indonesia’s cobalt production surged to almost 9,500 tonnes from 2,700 tonnes in 2021, with the potential to increase production by tenfold by 2030.
|Country||2022 Production (tonnes)||% of Total Production|
|🇵🇬 Papua New Guinea||3,060||1.5%|
Percentages may not add to 100 due to rounding.
In total, global cobalt production reached 197,791 tonnes, with the DRC contributing just under 145,000 tonnes of that mix.
The EV industry is the largest consumer of cobalt, accounting for approximately 40% of total demand. The exponential growth of the EV sector is expected to drive a doubling of global cobalt demand by 2030.
While the shift in cobalt production is notable, it is not without challenges. Plummeting cobalt prices, which fell almost 30% this year to $13.90 a pound, have severely impacted the DRC.
Furthermore, the longer-term prospects of cobalt could face hurdles due to efforts to reduce its use in batteries, partly driven by human rights concerns associated with artisanal cobalt mining in the DRC and related child labor and human rights abuses.
In a 2021 ruling by a federal court in Washington, Google parent Alphabet, Apple, Dell, Microsoft, and Tesla were relieved from a class action suit claiming their responsibility for alleged child labor in Congolese cobalt mines.
The Future of Cobalt
Despite ongoing efforts to substitute cobalt in battery applications, cobalt is expected to remain a vital raw material for the entire battery supply chain in the near future.
The demand for cobalt is forecasted to more than double by 2030 to 388,000 tonnes.
