The energy transition in Latin America and the Caribbean must consider how the materials incorporated in renewable energy technologies will be managed at the end of their useful life. The environmental discussion can no longer be limited to replacing fossil fuels with clean sources; it must also include the capacity to recycle, reuse, and recover value from the components that make this transformation possible.
Today, the region has 150 million solar panels and 16,000 wind turbines in operation, and these figures will continue to grow in the coming years. Meanwhile, lithium battery systems to support electrical grids are expanding rapidly. What today represents technological advancement and emissions reduction will tomorrow also be a growing volume of waste and materials that will require traceability, treatment, and new value chains.
The magnitude of the challenge is undeniable. OLACDE projects that by 2050 there will be 81 million tons of materials associated with energy transition technologies in the region, including 36 million tons of steel, 4 million tons of copper, and 10 million tons of aluminum. At the same time, the recoverable economic value of these materials could reach US$209 billion. This figure is revealing: the circular economy is a strategic component and complement to the energy transition.

For the region, this reality presents both an opportunity and a challenge. The opportunity lies in developing a new industry linked to recycling, materials recovery, remanufacturing, and reverse logistics. However, if countries do not prepare regulatory frameworks, infrastructure, and technical capabilities today, they will face environmental liabilities, disposal costs, and additional pressure on waste management systems that are already fragile in many areas.
The challenge is significant because the materials involved are neither homogeneous nor easy to manage. Recovering metals, glass, plastics, and other components present in technologies such as solar panels, batteries, and wind turbines requires traceability rules, recycling standards, clear responsibilities for manufacturers and importers, and public-private coordination to develop regional solutions.
The energy transition will only be sustainable if it avoids shifting the problem from emissions to waste. It is important to consider what happens to these clean technologies before, during, and after their use, as each panel, battery, and turbine also has a material footprint.
Latin America and the Caribbean have a comparative advantage: they can become a pioneering region in integrating decarbonization and a circular economy. But to achieve this, we must anticipate future needs. The coherence of the energy transition will be measured not only by the megawatts installed, but also by the capacity to close the materials cycle.
