Energy Transition Isn't Neutral: South America's Sovereignty Test
As the world's largest economies race to control the minerals, manufacturing capacity, and grid infrastructure of the energy transition, nations in the Global South face a choice that has nothing to do with climate targets and everything to do with who holds the levers of the next economic order.
In April 2026, energy ministers, civil society groups, and multilateral development banks gathered in Asunción for a conference on energy transition — a convening whose agenda listed the usual items: renewable capacity targets, financing mechanisms, just transition frameworks. But the conversation that mattered was running underneath those official headings, and it had nothing to do with kilowatts.
The question South American governments are quietly working through is not whether to transition — it is who gets to build the system, who owns the inputs, and under whose rules the new energy architecture will operate. The climate language is genuine. The geopolitical stakes are at least as real.
For the better part of three decades, a central narrative held that global economic integration was a rising tide that would lift all boats. Development would come; sovereignty would follow. What the energy transition is exposing is that the order in which those things arrived mattered enormously. Countries that secured control over their extractive and industrial capacity before global capital consolidated are now in a fundamentally different position from those that did not. Paraguay, Bolivia, Chile, and Argentina — nations with extraordinary renewable potential and critical mineral deposits — are navigating a landscape where the terms of engagement have shifted beneath their feet.
The Itaipu hydroelectric complex, straddling the Paraná River between Paraguay and Brazil, remains the clearest illustration of how energy infrastructure can be built on a country's territory and generate leverage for someone else's economy. The dam's output powers the region. The treaty's terms have been a source of Paraguayan grievance for decades, producing recurring renegotiation disputes that expose how difficult it is to claw back sovereignty once it has been ceded in a development deal. The conference in Asunción was, in part, a recognition that the next generation of energy infrastructure cannot be negotiated on the same terms.
What makes the current moment different from the hydrocarbon era is the pace at which the transition is being commodified. China, the European Union, and the United States are not simply offering financing for green projects — they are actively shaping which technologies get deployed, which standards get adopted, and which supply chains get锁死. Chinese state-backed lenders have financed hydroelectric projects and grid infrastructure across Southeast Asia and sub-Saharan Africa. European development finance attaches conditionality around governance standards and local benefit-sharing. Washington's approach has oscillated between export-credit competition and industrial-policy coordination with allies. Each model has a theory of development embedded in it. None is neutral.
For nations like Paraguay, the challenge is not rejecting any of these partnerships outright — that is not a viable option — but ensuring that the negotiations over hydroelectric capacity, critical mineral extraction, and grid interconnection happen on terms that reflect their own development timelines, not the strategic convenience of the financing party. The pressure to lock in long-term supply agreements for lithium, cobalt, or copper is real, and it is coming from multiple directions simultaneously. Signing these agreements prematurely, before domestic processing capacity exists, is how resource-rich nations remain resource-dependent.
The structural point here is straightforward. The energy transition is not a rising tide — it is a reallocation of economic power. The countries and blocs that control the minerals, the manufacturing scale, and the grid integration standards will shape the terms of trade for the next half-century. Nations in the Global South, including those with abundant renewable potential, are not bystanders to this process, but they are not yet in control of it either. The conference in Asunción was a useful moment to name that plainly: the transition is underway, the competition is real, and the decisions being made right now about infrastructure financing, supply agreements, and technology standards will determine whether South American nations are players in the new energy order or merely its raw-material suppliers.
The stakes are concrete. If current trajectories hold, the region will export more critical minerals in 2035 than it did in 2025 — but if processing capacity and industrial integration remain concentrated in manufacturing powers, the region will capture a smaller share of the value added than it did during the hydrocarbon era. That is a choice. It is also a consequence of choices made earlier, in different geopolitical conditions, and the people in Asunción in April 2026 were not pretending those earlier decisions had not happened. They were trying to make sure the next set of decisions are not made on someone else's terms.
The decisions made in the next five to eight years on energy infrastructure financing, grid integration standards, and mineral supply agreements will define Latin America's position in the global economy for the remainder of this century. The transition is coming. The terms are still being written.
