Introduction

FOR FOUR THOUSAND YEARS, HUMANS DEPENDED ON FIRE, CAPRICIOUS winds and currents, and manpower and horsepower to roam, build fortresses, and work the land. Energy was a rare and precious resource, movement was slow, economic growth sluggish. Progress came in fits and starts, and history tended to be made one slow step at a time.

Then, from the eighteenth century, humans used the steam engine to power their looms, propel locomotives, and float battleships to reign over the seas. Steam powered the first industrial revolution. This was the world’s first energy transition, and one underpinned by the use of an indispensable fuel: a black stone called coal.

In the twentieth century, humans cast aside steam for another innovation: the petrol engine. This technology made vehicles, boats, and tanks more powerful, and paved the way for a new machine — the aeroplane — to conquer the skies. This second industrial revolution was also an energy transition, this time relying on the extraction of another resource: a rock oil called petroleum.

The disruptive effects of fossil fuels on the climate since the turn of the current century have driven humanity to develop new and supposedly cleaner and more efficient inventions — wind turbines, solar panels, electric batteries — that can connect to high-voltage ultra-performance grids. After the steam engine and the internal-combustion engine, these ‘green’ technologies have shifted us into a third energy and industrial revolution that is changing the world as we know it. Like its two predecessors, this revolution draws on a resource so vital that energy experts, techno-prophets, heads of state, and military strategists already refer to it as The Next Oil of the twenty-first century.

What resource are we talking about?

Most people don’t have the slightest idea.

Changing the way we produce and therefore consume energy is humanity’s next great adventure. Political leaders, Silicon Valley entrepreneurs, proponents of more moderate consumption, Pope Francis, and environmental groups have urged us to make this change, curbing global warming and saving ourselves from a second flood. Never have empires, religions, and money been so aligned behind a single undertaking.1 The proof of this — described by former French president François Hollande as the ‘first universal agreement in our history’ — is neither peace treaty, nor trade deal, nor financial regulation.2 The Paris agreement that was signed in 2015 following the twenty-first conference of parties to the United Nations Framework Convention on Climate Change (COP 21) is, in fact, an energy treaty.

The technologies we use every day might change, but our primary need for energy will not. Yet, faced with the question of what resource could possibly replace oil and coal as we embrace a new and greener world, no one really knows the answer. Our nineteenth-century ancestors knew the importance of coal, and the enlightened man on the street in the twentieth century was well aware of the need for oil. But today, in the twenty-first century, we are unaware that a more sustainable world is largely dependent on rock-borne substances called rare metals.

Humans have long mined the big names in primary metals: iron, gold, silver, copper, lead, aluminium. But from the 1970s, we turned our sights to the superb magnetic, catalytic, and optical properties of a cluster of lesser-known rare metals found in terrestrial rocks in infinitesimal amounts. Some of the members of this large family sport the most exotic names: rare earths, vanadium, germanium, platinoids, tungsten, antimony, beryllium, fluorine, rhenium, tantalum, niobium, to name but a few. Together, these rare metals form a coherent subset of some thirty raw materials with a shared characteristic: they are often associated with nature’s most abundant metals.

As with all elements extracted from nature in Lilliputian quantities, rare metals are concentrates packed with remarkable properties. It is a long and painstaking process, for instance, to distil orange blossom essential oil, but the perfume and therapeutic powers of a single drop of this elixir continue to astound researchers.3 Producing cocaine deep in the Colombian jungle is no easier feat, yet the psychotropic effects of just one gram of the powder can completely deregulate your central nervous system.4

The same applies to the rarest of the rare metals. Eight and a half tonnes of rock need to be purified to produce a kilogram of vanadium; sixteen tonnes for a kilogram of cerium; fifty tonnes for the equivalent in gallium; and a staggering 1,200 tonnes for one miserable kilogram of the rarest of the rare metals: lutecium.5 (See the periodic table of elements in Appendix 1.) These effectively form the ‘primary asset’ of the Earth’s crust: a concentration of atoms with outstanding properties, fine-tuned by billions of years of geological activity. Once processed industrially, a minute dose of these metals emits a magnetic field that makes it possible to generate more energy than the same quantity of coal or oil. And this is the key to ‘green capitalism’: the replacement of resources that emit billions of tonnes of carbon dioxide with resources that do not burn and therefore do not generate the slightest gram of it.

Less pollution, and at the same time a lot more energy. Tellingly, one of these elements was given the name ‘promethium’ by chemist Charles Coryell in the 1940s.6 His wife, Grace Mary, suggested the name, based on the Greek myth of the Titan Prometheus, who was helped by the goddess Athena to break into the realm of the gods, Olympus, and steal the sacred fire … to give to humanity.

The name says a great deal about the promethean power that we have acquired by harnessing rare metals. Like demigods, we have carved out a multitude of applications in two fundamental areas of the energy transition: supposedly ‘green’ technologies and digital technologies. Today, we are assured that the convergence of the two will create a better world. The first examples of this convergence (wind turbines, solar panels, and electric cars) are packed with rare metals to produce decarbonised energy that travels through high-performance electricity grids to enable power savings. Yet these grids are also driven by digital technology that is heavily dependent on these same metals. (See Appendix 11 for the main industrial applications of rare metals.)

Jeremy Rifkin, a leading US theorist of this energy transition and the resulting third industrial revolution, takes this a step further.7 He writes that the crossover of green technologies and new technologies of information and communication (NTIC) already enables each of us to abundantly and inexpensively generate and share our own ‘green’ electricity. In other words, the mobile phones, tablets, and computers we use every day have become the key components of a more environmentally friendly economic model. Rifkin’s prophecies are so compelling that he now counsels numerous heads of state, and is advising a region in the north of France on how best to implement its new-energy models.8

Recent history lends substance to his predictions: in the space of ten years, wind energy has increased seven-fold, and solar power by forty-four. Renewable energy already accounts for 19 per cent of world final energy consumption, with Europe planning to increase its share to 27 per cent by 2030.9 Even technologies based on combustion engines use these metals to make vehicle and aircraft design lighter, more efficient, and therefore less fossil-fuel-intensive.

Enter the military, which is pursuing its own energy transition. Or strategic transition. While generals are unlikely to lose sleep over the carbon emissions of their arsenals, as oil reserves dwindle they will nevertheless have to consider the possibility of war without oil. Back in 2010, a highly influential American think tank instructed the US army to end its reliance on fossil fuels by 2040.10 How will they do this? By using renewable energy, and by raising legions of electrically powered robots. These remote-controlled weapons, which can be recharged using renewable-energy plants, would be a formidable destructive force and solve the conundrum of getting fuel to the front line.11 This form of combat is, in fact, already colonising new virtual territories: cyber armies alone could win future conflicts by targeting the enemy’s digital infrastructure and altering its telecommunication networks.12

Like army generals, we too are engaged in a transition to a connected world in which the way we use digital technology will replace certain resources with nothing but … thin air: clouds, intangible messaging, and online traffic instead of highway traffic. The digitalisation of the economy — we are assured — will drastically reduce our physical footprint on the living world. We stand only to gain from an energy and digital revolution: two technological forces marching hand in hand towards a better world.

Even the face of international relations is changing, as diplomats use rare metals to drive a geopolitical transition. Indeed, the rise of new non-carbon energy, say geopolitical experts, will upend the relationship between oil-producer states and oil-consumer states. It will enable the US to progressively shift its warships from the Straits of Hormuz and Malacca — today’s vital oil-transit chokepoints — and rethink its partnership with the Gulf petro-powers. As for the European Union, less reliance on Russian, Qatari, and Saudi Arabian fossil-fuel imports will increase its member states’ energy sovereignty.

For all these reasons, the energy transition promises to be positive — although implementing it will be no easy feat so long as we have not seen the last of oil and coal.13 The world that is taking shape before our eyes nevertheless gives us reason to hope. More modest energy consumption will naturally stave off global tensions around the ownership of fossil-fuel sources, create green jobs in leading industrial sectors, and make Western countries serious energy contenders once again.14 Irrespective of what Donald Trump thinks, this transition is unstoppable: it involves big money that is pulling in players from all across the economy — including the oil giants.

This energy transition traces its beginnings to Germany in the 1980s,15 and culminated in Paris in 2015, when 195 nations jointly agreed to accelerate this formidable journey. Their goal: to keep the increase in global warming to below two degrees by the end of this century, mainly by replacing fossil fuels with green energy.

But just as the delegates were about to sign the Paris agreement, a wise old man with pale-blue eyes and a bushy beard, dressed like a hermit descending from the mountain, entered the vast hall of COP 21. With an enigmatic smile on his face, he parted the amassed heads of state. Reaching the podium, he began to speak in a deep and deliberate voice: ‘Your intentions are charming, and we can all rejoice in the new world to which you are about to give birth. But you are blind to the perils inherent in your audacity!’

Silence.

Turning to the Western delegates, he continued: ‘This transition will cripple entire swathes of your economies, and the most strategic at that. It will plunge hordes of workers into retrenchment, triggering social upheaval that will shake your democratic foundations. Even your military sovereignty will be compromised.’

Now addressing all delegates, he added: ‘The energy and digital transition will devastate the environment in untold ways. Ultimately, the environmental price of building this new civilisation is so staggering that there is no guarantee you will succeed.’

He ended with an oracular message: ‘Your power has blinded you to the point that you have lost the humility of the sailor before the ocean, the climber before the mountain. You forget that the Earth will always have the final say!’

The wise old man is, of course, a figment of my imagination. But the message is real enough, and crystal clear: the 196 delegations in Le Bourget that day signed the Paris agreement and committed to this Herculean task without considering a few crucial questions.16 Where and how are we going to procure the rare metals without which this treaty will fail? Will there be winners and losers on the new chessboard of rare metals, as there were for coal and oil? And what will be the economic, social, and environmental cost of securing their supply?17

For eight years and across a dozen countries, I researched these new rare substances that are already upending our world. I ventured deep into mines in the tropics of Asia, eavesdropped on deputies in the corridors of the French National Assembly, flew over the deserts of California in a light aircraft, bowed before the queen of a tribal community in southern Africa, travelled to the ‘cancer villages’ of Inner Mongolia, and blew the dust off old parchments in venerable London institutions.

Across four continents, men and women involved in the opaque and underground world of rare metals shared with me a very different and far darker tale of the energy and digital transition. By their account, the emergence of these new substances in the wake of fossil fuels has not done us or the planet any of the favours we would expect from a supposedly greener, friendlier, and more insightful world — far from it.

Great Britain dominated the nineteenth century, thanks to its hegemony over global coal production. Many of the events of the twentieth century can be seen through the lens of US and Saudi Arabian control over oil production and supply routes. In the twenty-first century, one state is in the process of dominating the export and consumption of rare metals. That state is China.

Consider this economic and industrial observation: by committing to the energy transition, we have flung ourselves headlong into the jaws of the Chinese dragon. Arguably, the Middle Kingdom holds a near monopoly over a profusion of rare metals without which low-carbon and digital energies — the very foundations of the energy transition — cannot exist. And, as I will address later in this book, China has used barely credible chicanery to position itself as the sole supplier of the most strategic of the rare metals. Known as ‘rare earths’, they are difficult to substitute, and the vast majority of industrial groups cannot do without them.18 (See Appendix 12 for the main industrial applications of rare earths.)

And so the West has placed the fate of its green and digital technologies — the cream of its industries of the future — in the hands of just one nation, while China is nurturing its own technologies and playing hardball with the rest of the world by putting a cap on the export of those resources. The result: serious economic and social consequences for the rest of the world.

Next, an ecological observation: our quest for a more ecological growth model has resulted in intensified mining of the Earth’s crust to extract the core ingredient — rare metals — with an environmental impact that could prove far more severe than that of oil extraction. Changing our energy model already means doubling rare metal production approximately every fifteen years. At this rate, over the next thirty years we will need to mine more mineral ores than humans have extracted over the last 70,000 years. But the shortages already looming on the horizon could burst the bubble of Jeremy Rifkin, green-tech industrialists, and Pope Francis, and prove our hermit right.

The third observation relates to geopolitics and the military. The continued existence of the most sophisticated Western military equipment (robots, cyberweapons, and fighter planes, including the US’s supreme F-35 stealth jet) also partly depends on China’s goodwill. This has US intelligence leaders concerned, especially as one high-ranking US army officer states that ‘only war can now stop Beijing controlling the South China Sea’.19

This latest scramble for resources is already heightening tensions over ownership of the most abundant deposits, sparking territorial conflicts in peaceful backwaters apparently of interest to no one. Fuelling this thirst for rare metals are a burgeoning global population set to reach 8.5 billion by 2030, the boom in new modes of high-tech consumption, and the growing convergence of Western and emerging economies.20

By seeking to break free from fossil fuels and turn an old order into a new world, we are in fact setting ourselves up for a new and more potent dependence. Robotics, artificial intelligence, digital healthcare, cybersecurity, medical biotechnology, connected objects, nanoelectronics, driverless cars … the most strategic sectors of the economies of the future, all the technologies that will exponentially increase our computing capacity and modernise how we consume energy, our daily routines, and even our most significant collective choices will depend entirely on rare metals. These resources will provide the fundamental building blocks of the twenty-first century. Yet our addiction is already pointing to a future so far unpredicted. We thought we could free ourselves from the shortages, tensions, and crises created by our appetite for oil and coal. Instead, we are replacing these with an era of new and unprecedented shortages, tensions, and crises.

From tea to black oil, nutmeg to tulips, saltpetre to coal, commodities have been a backdrop to every major exploration, empire, and war, often altering the course of history.21 Today, rare metals are changing the world. Not only are they polluting the environment, but they are jeopardising economic stability and global security. In the twenty-first century alone, their use has consolidated China’s supremacy and accelerated the weakening of the West that began at the turn of the millennium.

But the rare metals war is far from lost. China has made some colossal errors; the West can respond; and the technical progress we have yet to make is bound to transform how we generate wealth and energy.

Until then, this book recounts the dark side of the story of the world that awaits us. It is an undercover tale of a technological odyssey that has promised so much, and a look behind the scenes of our lavish and ambitious quest that involves risks as formidable as those it sets out to resolve.
