As the global demand for critical minerals surges, South America finds itself at the forefront of a contentious debate surrounding the sustainability of the energy transition. Countries like Brazil, Argentina, and Chile are increasingly entangled in a resource-driven economy that raises significant concerns about whether this shift towards greener technologies is genuinely sustainable or merely a continuation of traditional extractivist practices. The region’s rich deposits of lithium and copper are pivotal for electric vehicle batteries and renewable energy systems, yet their extraction poses serious environmental and social challenges.
The Lithium Triangle, encompassing Argentina, Bolivia, and Chile, is home to over half of the world’s lithium reserves. This metal has become essential in the production of electric vehicle batteries and other technologies critical to decarbonization efforts. However, the extraction processes employed in these areas often exacerbate existing environmental strains. In Chile’s Atacama Desert, for instance, lithium mining relies heavily on water-intensive methods that threaten local ecosystems and water supplies in one of the driest regions on Earth. Similar issues are reported in Argentina, where Indigenous communities face water depletion and disruption of traditional livelihoods due to mining activities.
In northern Argentina, provinces like Jujuy and Salta have attracted substantial foreign investment in lithium mining. While the government promotes this sector as a means of economic modernization and integration into global markets, local communities express concerns regarding inadequate consultation processes with Indigenous groups, disputes over land rights, and a lack of transparency in how mining revenues are distributed. Critics argue that this model perpetuates an extractivist approach where multinational corporations reap most of the benefits while local populations bear the environmental costs.
Chile positions itself as a leader in responsible lithium production; however, evidence from the Atacama Desert reveals a more complex reality. The expansion of evaporation ponds amid increasing water scarcity raises questions about the sustainability claims made by the industry. Local Indigenous groups report that their territories are under threat from ecological degradation linked to lithium extraction activities. This contradiction highlights the tension between supporting global clean energy supply chains and addressing environmental pressures at home.
Brazil’s energy strategy also reflects similar tensions despite not being part of the Lithium Triangle. The country has long championed biofuels as a renewable energy source; however, large-scale production is increasingly associated with agricultural expansion, deforestation, and rural displacement. Moreover, Brazil’s ambitions in hydrogen and clean energy may prioritize export-oriented megaprojects over local energy needs, raising concerns about potential greenwashing practices that fail to address the full environmental impacts.
The ongoing energy transition across South America is reshaping landscapes but often perpetuates inequities. Indigenous populations are increasingly vocal about their exclusion from decision-making processes related to resource extraction. Many argue that current practices mirror historical patterns where external markets benefit disproportionately from local resources while communities face increased environmental burdens.
Emerging critiques of “green extractivism” suggest that traditional extractive models cannot adequately support environmental goals without fundamentally altering their social and ecological impacts. Key issues include high water consumption during lithium production, weak regulatory enforcement in mining regions, limited community benefit-sharing, and a concentration of value within global supply chains. These factors indicate that without significant changes to governance structures and community engagement practices, the energy transition risks merely shifting environmental burdens rather than alleviating them.
The South American experience underscores a broader global challenge: achieving decarbonization is not solely a technological issue but also a political and ethical one. A truly sustainable transition necessitates stronger environmental governance, meaningful participation from Indigenous communities, diversified economic models beyond raw material exports, and recognition of territorial rights alongside ecological limits. Absent these elements, there is a real danger that the current transition will simply rebrand existing extractive systems while continuing to impose costs on vulnerable regions.
