Demand for critical minerals essential for clean energy technologies such as electric vehicles and wind turbines will soar as the world attempts to meet its net-zero goals.

The International Energy Agency (IEA) has compiled a report that stresses that such demand will also bring potential energy security hazards as well as supply disruption.

The report, The Role of Critical Minerals in Clean Energy Transitions, is the most comprehensive global study to date on the central importance of minerals such as copper, lithium, nickel, cobalt and rare earth elements in a secure and rapid transformation of the global energy sector.

“Today, the data shows a looming mismatch between the world’s strengthened climate ambitions and the availability of critical minerals that are essential to realising those ambitions,” said Fatih Birol, executive director of the IEA. “The challenges are not insurmountable, but governments must give clear signals about how they plan to turn their climate pledges into action. By acting now and acting together, they can significantly reduce the risks of price volatility and supply disruptions.”

The report, part of the IEA’s flagship World Energy Outlook series, underscores that the mineral requirements of an energy system powered by clean energy technologies differ profoundly from one that runs on fossil fuels. A typical electric car requires six times the mineral inputs of a conventional car, and an onshore wind plant requires nine times more mineral resources than a similarly sized gas-fired power plant.

Demand outlooks and supply vulnerabilities vary widely by mineral, but the energy sector’s overall needs for critical minerals could increase by as much as six times by 2040, depending on how rapidly governments act to reduce emissions. Not only is this a massive increase in absolute terms, but as the costs of technologies fall, mineral inputs will account for an increasingly important part of the value of key components, making their overall costs more vulnerable to potential mineral price swings.
