Climate change has been disrupting Latin American efforts to make its energy more renewable. Countries are now searching for new solutions and everything from nuclear power to green hydrogen is being debated.

In Ecuador and Cuba, power cuts for hours at a time, sometimes even days. In Brazil, energy bottlenecks. Although Latin America is seen as a global forerunner in renewable energies, the impact of climate change is starting to cause problems. Droughts lasting weeks mean less water flowing through rivers and water reservoirs that power hydroelectric plants. And the less water, the less electricity.
Now countries in the region are beginning to squabble over distribution too.
Colombia has halted electricity exports to Ecuador, citing concerns for its own power supply. Colombia has also been suffering a severe drought
Even though the causes for the power problems are unique to each country, the consequences are the same: energy rationing and power blackouts. This is why many countries are now debating how best to stablize their energy supplies.

Nuclear energy up
El Salvador, for example, plans a return to nuclear energy. "We want to have the first research reactor by 2030," Daniel Alvarez, head of the country's General Directorate of Energy, Hydrocarbons and Mines, announced at a forum organized by the Latin American Energy Organization in October.
Other countries are also showing renewed interest in nuclear energy, with a new generation of small modular reactors seen as particularly promising. The general opinion is that nuclear energy is free of emissions and can therefore be classified as green.
Lithium hype
Lithium also belongs to the energy debate in Latin America. Lithium is an indispensable part of electric vehicle (EV) batteries and it is hoped that carbon-neutral EVs will one day replace fossil-fuel powered engines on the street. At least, that's the plan. But resistance is growing in many Latin American countries.
As droughts become more frequent, they are increasingly wary of an extraction process that requires large volumes of water. In Peru, a mining project high in the Andes is drawing criticism. There, the Macusani Yellowcake mining company, a subsidiary of the Canada-based American Lithium Corp., is looking to mine 9.5 million tons of lithium on the Quelccaya glacier in the Carabaya region.
Environmental activist Vito Calderon has criticized the way the project affects the water supply for local communities. "The freshwater from the region flows into the Inambari, Urubamba and Azangaro basins, which feed Lake Titicaca," he told Radio France Internationale. Calderon fears the freshwater could be contaminated or removed from the natural cycle.
What about green hydrogen?
The initial excitement over what is known as green hydrogen has also become more muted. "Worldwide doubts about the strategic industry for Chile's future" Chilean online news outlet Emol wrote a few days ago, summing the general mood up. The high cost of investing in green hydrogen is also causing hesitation.
Instead, Alex Godoy-Faundez, director of the sustainability research center at Chile's University of Desarrollo has called for more realism and for taking small, manageable steps.
"Timelines should outline short-term goals that ensure that investment projects are profitable and eco-friendly,” Godoy-Faundez said.
Investment in Brazil
However in Latin America's largest country, Brazil, enthusiasm over green hydrogen has continued unabated. There's almost nowhere in the world like Brazil's undeveloped northeast, where electricity and therefore green hydrogen can be produced from renewable sources so cheaply, the country's media enthuse. Brazil could become a new global energy hub, they suggest. Foreign investors have already done deals with Brazilian states like Ceara and Pernambuco.
"Unfortunately, German investors are not among them," Ansgar Pinkowski, founder of the Brazil-based agency Neue Wege ("new paths" in English), told DW. His business specializes in providing information on the green energy transition and contacts between Europe and Brazil.
"With the recently passed laws for sustainable hydrogen, the risks for investors have also become much lower and more calculable," he said. As a result he predicts that, "we will see very strong economic growth in the region in the next few years, from which all sections of the population will hopefully benefit."
