At this point it seems safe to say that the Green Revolution is not going as planned. In particular, mineral resource extraction was meant to decline as part of the energy transition away from fossil fuels, but it is doing the opposite — even as fossil-fuel consumption also hit a new high last year. Wind and solar power are mineral-intensive. Mineral resources like manganese, graphite, cobalt and lithium are critical to the batteries used in electric vehicles; electric vehicles are critical to the energy transition; therefore the mining of these minerals, which can be a very environmentally damaging process, is expected to take place on a large scale, damaging the environment in order to save it.
The other main driver for increased mining is digital technology. Part of this is again demand for batteries. Rechargeable batteries require lithium and cobalt. Without them there is no mobile Internet, no laptops or mobile phones. But digital technology also uses other minerals, like rare earths, and above all it uses minerals that produce energy. The data-center infrastructure that digital communications have come to depend on is making huge energy demands that are expected to increase in order to support energy-intensive artificial-intelligence computing. The digital revolution was meant to be good for the planet. All those books and newspapers that would no longer have to be printed, transported, and sold by retailers. All those carbon-footprint business trips that could be replaced by meetings online. Yet digitization seems to be resulting in more rather than less resource extraction. The digital world is damaging the physical world while pretending to transcend it.
The energy transition seems to be entering an era of paradox. It isn’t simply that green and digital technologies are dirty. It is that they are getting dirtier because major states seek both energy independence and secure high-technology supply chains. Climate change, it is often said, is a global problem requiring global solutions. But if the solutions are to be found, it appears that they will be found through the complete opposite of global cooperation. The Biden administration has just announced plans to spend more than $3 billion trying to secure US supply chains of critical minerals and build upstream capacity. That means, for example, $225 million toward the mining of lithium in Arkansas, and $166 million to help extract manganese in Arizona.
As US National Economic Adviser Lael Brainard explained, the goal is “an end-to-end supply chain for batteries and critical minerals here in America, from mining to processing to manufacturing and recycling, which is vital to reduce China's dominance of this critical sector." If a nation other than China were producing 77 percent of the world’s graphite supply or 60 percent of its rare earths, the situation would be different. As it is, geopolitical circumstance are shaping the energy transition into forms it would not take on a market basis. The desire for national data security, combined with the energy needed for data processing, points in the same direction of nationalized production that is inherently inefficient.
From an investor perspective, one clear option is to invest in extractives. However, the political risks can be high. If the US-China race to create mutually exclusive economies can be taken as a constant for the next generation or two, the specific policies will vary. If Donald Trump returns to the White House, he could well de-fund the EV battery projects, endangering new mining in Arizona and Arkansas. More interesting are investments that, in effect, eliminate political competition over a resource. For several years, electric-vehicle automakers have been trying to reduce their political exposure to Chinese dominance of rare-earths production. Of course one way to do that is through diversifying mineral supplies. A new project in Canada aims at just that. But another way is to engineer EV batteries that do not require rare earths. BMW in its newer EV lines has eliminated rare earths. In that instance, geopolitical supply-chain worries led to a reduction in resource extraction. Private-sector innovation could yet produce more ways of avoiding politically driven supply constraints. It would be a peculiar way to move toward the global transition away from carbon but it might be one way that really works.
