The Dark Side of Clean Energy and Digital Technologies by Guillaume Pitron, review — our dirty future

When Donald Trump offered to buy Greenland from Denmark in 2019 it was dismissed as illegal and absurd. However, the president’s expression of interest was far from absurd, says Guillaume Pitron. Under its soil Greenland boasts one of the largest concentrations of the rare metals that the world will need to power electric cars, computers, mobile phones, robots, solar power plants, artificial intelligence and many high-tech “green” innovations that have not been dreamt up yet. If Trump were after those minerals, buying Greenland would have been a smart move.

The global production and sales of rare metals are dominated by China. It mines so much of them on home soil and controls so much of their extraction in Africa and elsewhere that it oversees up to 95 per cent of the global production of certain minerals. This puts Beijing in charge of “the oil of the 21st century”, writes Pitron, which is a problem for western nations because it means China can restrict supply and drive prices up or down at will, as Opec does with oil. We have “entrusted a precious monopoly of mineral sovereignty to potential rivals”, he notes.

China’s dominance is not the only problem with the rare earth metals market. In our rush to develop new green technologies, Pitron argues, we forget that many of the innovations that we are told will help to combat climate change are very dirty. Electric cars, it’s true, do not emit CO2 or NO2. But when you factor in the environmental cost of extracting all the rare earth minerals that go into making batteries, it is far from clear whether their overall footprint is better than existing petrol models.

Rare earth minerals production is very energy intensive. Extracting a single kilogram of some requires mining as much as 1,200 tonnes of rock. “Clean energy is a dirty affair,” Pitron writes. He drives home his point by touring villages near polluted lakes in China that are known locally as “cancer villages”.

We all love the communications revolution spawned by mobile phones, tablets, PCs and video and audio streaming services. But Pitron points out that all the devices we use consume rare metals and that the servers that power them are hugely energy hungry. He cites studies showing that the communications industry consumes 10 per cent of global electricity and produces 50 per cent more greenhouse gases than the aviation industry.

And all this is before we get to the sulphurous issue of recycling. Recycling large electric car batteries could be the next diesel scandal, he warns. He quotes Carlos Tavares, the boss of the newly merged Peugeot Fiat group, who warns: “If we are instructed to make electric vehicles, authorities and administrations must assume the scientific responsibility of this choice. I don’t want to find that in 20 or 30 years we’ve fallen short in aspects such as battery recycling.”

If the message of this book is a tough one, it can be tough going too. It was written in French and has too often been translated literally. Pitron’s style is “tell, not show”, making it read more like a lecture on the geopolitics of raw materials than what it purports to be: a wake-up report on a looming crisis. There are too many unnamed sources for my taste. And some of the sources we’re introduced to I’m not sure we need to be burdened with. The deliberations of the China Nonferrous Metal Mining Group Corporation will be of scant interest to most readers.

Yet it is worth persevering with, because much of what he says will be new to readers. I did not know, for instance, that America’s most high-tech weapons are dependent on magnets and other components made in China using rare metals mined in China. Nor that up to 90 per cent of electric car batteries are made in China. This dependency makes the issue of Chinese-made Huawei communications equipment creeping into our telecoms networks look like small beer.

I also had no idea that as well as all the rare earth minerals we will need to extract to drive the green energy revolution we will also need to mine vast quantities of more everyday metals. The case of wind turbines is alarming. To keep up with projected market growth in turbine demand and construction will require by 2050 some 3,200 million tonnes of steel, 310 million tonnes of aluminium and 40 million tonnes of copper, Pitron calculates. Chuck in all the raw materials needed to build everything from billions of green car chassis to new solar power plants and “by 2050, we will have to extract more metals from the subsoil than humanity has extracted since its origin. Our 7.5 billion contemporaries will absorb more mineral resources than the 108 billion humans who have walked the Earth to date.”

In the post-Covid, climate emergency era, we will need to rebuild business and consumer industries in a genuinely responsible way. This book contains few solutions to the problems it identifies. But, after the dieselgate scandal, recognising that the latest technologies might not be as green as we like to think is a good place to start planning for a better world.

  1. Ive had this argument with a few before, human population is unsustainable both in the current form and even worse under a green new world.
    People are blown away when you say that covid isnt the virus we need as its not deadly enough, we need something that indiscriminatly smashes half the worlds populatio, No green agenda needed after that.

  2. Iam a stupid boy, I agree ,even if every human is removed from the planet it’s not the end only the end of us, a hundred years later the planet would be mended for all the other life that will flourish once the greedy wasteful human stain has gone.
    Whats the big deal about the end of humans as the dominant species?

  3. The diesel thing was such a cock up.
    The Volkswagen ‘great revelation’ on emissions story was but the tip of the tip of the iceberg.

    The British Govt pushed diesel cars
    Totally political without understanding it at all.
    I contend the same is occurring with electric cars (which are more useless)

    Note how these things work.
    There is a test pack to see how gullible people are.
    eg. Global warming.
    A complete fake – fiddle the figures, Johnny Sheep panics a little bit ; tell horror stories about what the planet will be like in 20 years (and when we get there , Nada, never happened).
    Phase II: Drum home the nonsense and fear to Johnny Sheep’s 8 year old daughter in the re-education camps (formerly used as school classrooms) and the fear mounts.
    Then bait and switch… ta da …. a bad cold that kills really old people will wipe out the planet!!
    The fear is multiplied beyond any reason and carried by media filth puppets and the politicians by and large are subordinated through decades of ‘campaign contributions’ and trips to rapey islands in the Caribbean to just go along with it.

    So, start with Diesel cars – caught out – but then do the same with electric cars – an even more stupid idea.

    Diesel cars were pushed in Britain in the 2000 to 2010 decade as an alternative to ‘evil petrol’
    Whaaaaat ???
    An inferior product (for domestic vehicles, OK for delivery vehicles, taxis) used to power cars that generally do lots of under 8 km trips, start stop; start stop.
    It was completely daft, but promoted by Govt.

    The Camel. A Horse designed by a committee.
    And we know about horses in the NZ Govt !!
    So pushing electric cars is no surprise.
