The rush to 'go electric' comes with a hidden cost: destructive lithium mining

Thea Riofrancos

As the world moves towards electric cars and renewable grids, demand for lithium is wreaking havoc in northern Chile

The Atacama salt flat is a majestic, high-altitude expanse of gradations of white and grey, peppered with red lagoons and ringed by towering volcanoes. It took me a moment to get my bearings on my first visit, standing on this windswept plateau of 3,000 sq km (1,200 sq miles). A vertiginous drive had taken me and two other researchers through a sandstorm, a rainstorm and the peaks and valleys of this mountainous region of northern Chile. The sun bore down on us intensely – the Atacama desert boasts the Earth’s highest levels of solar radiation, and only parts of Antarctica are drier.

I had come to the salt flat to research an emerging environmental dilemma. In order to stave off the worst of the accelerating climate crisis, we need to rapidly reduce carbon emissions. To do so, energy systems around the world must transition from fossil fuels to renewable energy. Lithium batteries play a key role in this transition: they power electric vehicles and store energy on renewable grids, helping to cut emissions from transportation and energy sectors. Underneath the Atacama salt flat lies most of the world’s lithium reserves; Chile currently supplies almost a quarter of the global market. But extracting lithium from this unique landscape comes at a grave environmental and social cost.

In the mining installations, which occupy more than 78 sq km (30 sq miles) and are operated by multinationals SQM and Albemarle, brine is pumped to the surface and arrayed in evaporation ponds resulting in a lithium-rich concentrate; viewed from above, the pools are shades of chartreuse. The entire process uses enormous quantities of water in an already parched environment. As a result, freshwater is less accessible to the 18 indigenous Atacameño communities that live on the flat’s perimeter, and the habitats of species such as Andean flamingoes have been disrupted. This situation is exacerbated by climate breakdown-induced drought and the effects of extracting and processing copper, of which Chile is the world’s top producer. Compounding these environmental harms, the Chilean state has not always enforced indigenous people’s right to prior consent.

These facts raise an uncomfortable question that reverberates around the world: does fighting the climate crisis mean sacrificing communities and ecosystems? The supply chains that produce green technologies begin in extractive frontiers like the Atacama desert. And we are on the verge of a global boom in mining linked to the energy transition. A recent report published by the International Energy Agency states that meeting the Paris greement’s climate targets would send demand skyrocketing for the “critical minerals” used to produce clean energy technologies. The figures are particularly dramatic for the raw materials used to manufacture electric vehicles: by 2040, the IEA forecasts that demand for lithium will have increased 42 times relative to 2020 levels.

1. Other than abandoning technology

and going to nature, everything has a price.

2. True, but ... is it really worth it?

People aren't talking enough about what 'going green' will actually entail, esp with regards to mining expansion and land use.

Many people think it's this obvious panacea that is only not happening because of the greedy fossil fuel companies ... but it's a lot more complex than that.

IMHO the only way out of this mess is negative population growth, people worldwide accepting that the days of plenty are over, and getting away from a world economy based on perpetual growth.

No way are we maintaining our current average standard of living and population expansion while simultaneously significantly reducing CO2 the way we need to to avert climate catastrophe.

Not without some technological miracle, such as viable Fusion reactors.

3. I think the answer

is to attempt to find the path of least damage, not eliminate all damage.

And to try and repair or replace what damage you do cause.

Can we mine lithium in a better way? If so, do that.
If not, then compensate for the damage caused as best we can.
