Uruguay’s green power revolution: rapid shift to wind shows the world how it’s done

Stung by 2008’s oil price spike, Uruguay now produces up to 98% of its electricity from renewables. Can other countries follow suit?

It was the 2000s, and fossil fuel prices were rising worldwide. After a period of volatility in the 1980s, the crude oil price per barrel had reached one of its lowest points – $20 – at the end of 2001 but then, over the course of six years, it tripled before a new oil shock saw prices surpass those of the 1970s, reaching a record $145 a barrel on 3 July 2008.
Uruguay imports its oil, so it had a problem. Demand for energy in the country had grown by 8.4% the previous year and household energy bills were increasing at a similar rate. The 3.4 million-strong population was becoming restless. Lacking alternatives, President Tabaré Vázquez was forced to buy energy from neighbouring states at higher prices, even though Argentina, Uruguay and Paraguay had a mutual aid agreement in case of emergency conditions.
To escape the trap, Vázquez needed rapid solutions. He turned to an unlikely source: Ramón Méndez Galain, a physicist who would transform the country’s energy grid into one of the cleanest in the world.
Today, the country has almost phased out fossil fuels in electricity production. Depending on the weather, anything between 90% and 95% of its power comes from renewables. In some years, that number has crept as high as 98%.
Phasing out fossil fuels was a central issue at Cop28. After a week of tense negotiations in Dubai, countries agreed to transition away from fossil fuels within energy systems – but campaigners, governments and environmental experts continue to debate how to make that transition.
Physicist Ramón Méndez Galain: ‘I thought I could understand a little about this problem.’
One answer could lie in what Uruguay has achieved within a decade and a half.
“I had been working abroad for 14 years, and when I came back, there was this energy crisis, but the only solution people were giving was to install a nuclear power plant – that was it,” Galain remembers. “I was a nuclear physicist, so I thought I could understand a little about this problem.”
The more Galain researched the issue, the more he became convinced that nuclear power was not the answer for Uruguay. Instead, he argued, it was renewables. He published his findings in a paper that laid out his belief that the country should go all in on wind power. Soon after, he received a phone call inviting him to become Uruguay’s energy secretary and to implement his plan.
“Imagine my surprise,” Galain says. “This was crazy. But I did something even more crazy: I accepted.”
Uruguay is a small country – about 26% smaller than the UK by area – wedged between two giants. Argentina’s sprawling capital, Buenos Aires, lies 31 miles (50km) south of the mouth of the Rio de la Plata, which forms part of the border between the two countries, while Uruguay shares its northern border with Brazil.
In this context, the country is easily overlooked. However, economically it is a South American success story. Its GDP per capita was £16,420 in 2022, according to the World Bank, the highest on the continent; only a tiny fraction of its population lives in extreme poverty. The country has a burgeoning middle class – accounting for about 60% of the population – and there are high expectations for lifestyle and opportunities.
Such demographic change has driven demand for the trappings of a contemporary, 21st-century lifestyle. Homes are fitted with washing machines and dishwashers, and air-conditioning units have become commonplace, as have vast flat-screen TVs and connected devices.

All of that requires power. Over the course of about a decade, Uruguay, under the stewardship of Galain, installed about 50 windfarms across the country, decarbonised the grid and bolstered its hydropower.
The biggest challenge, however, was to change the “narrative” about renewables. Back then, sustainable energies were still surrounded by many misconceptions, says Galain: they were too expensive, too intermittent or would raise unemployment – and changing these stories proved vital to getting buy-in from all levels of society.
“No one believed we could do it. We needed new solutions. We needed to do things differently,” he says. “Today, even members of that cabinet say to me: ‘When you were saying those things on TV in 2008, we were thinking, how are we going to explain this when we fail?’”
Galain says there needed to be a “strong national narrative” to make it work. “I told people this was the best option even if they don’t believe climate change exists. It’s the cheapest and not dependent on crazy fluctuations [in oil prices].”
With that narrative, the government set about winning over a sceptical populace. One initial concern was that jobs would be lost in the energy sector. Instead, about 50,000 new jobs were created – a large number in a country with such a small population. The idea of a “just transition”, in which nobody was left behind, became central, and some workers were offered places on retraining schemes to adapt to the new normal.

Others were able to take advantage of the changes. Santiago Revello, 52, owns a beef farm in central Uruguay, about 175 miles north of the capital, Montevideo. Beef production is a primary industry across the country, owing to its vast swathes of grasslands.
The farm broke even financiallybut in 2009, the Revello family was debating whether to sell its farm. That was when Revello met Fernando Schaich, who ran what was previously a small energy-efficiency consultancy, and had learned about the country’s transition to renewables.
