Uruguay now runs on nearly 100% renewable electricity

Story: 2025 C.E.  |  Last updated: April 20, 2026

A small South American nation of 3.5 million people has quietly achieved something most large economies are still decades away from: Uruguay renewable electricity now accounts for between 97% and 99% of the country’s total power supply — and has done so consistently for years. No experimental technology. No heroic sacrifice. Just a decade of disciplined policy, the right mix of energy sources, and a very pragmatic reason to act.

At a glance

• Renewable electricity share: Uruguay sources 97–99% of its electricity from wind, solar, hydropower, and biomass — among the highest shares of any country on Earth.
• Economic driver: The government pursued clean energy primarily to cut dependence on costly fossil fuel imports, stabilizing prices for households and businesses alike.
• Speed of change: The transformation took roughly 10 years, relying entirely on proven, commercially available technologies — no nuclear power, no experimental systems.

How Uruguay built a reliable clean grid

Uruguay’s grid draws from four sources: wind, solar, hydropower, and biomass. That diversity is intentional — and it is the system’s greatest strength.

Hydropower provides a stable baseline. Wind has grown into a major contributor, accounting for a large share of total generation on most days. Solar capacity continues to expand, adding further cushion. When wind drops, hydro and biomass ramp up. The result is a grid that stays balanced without depending on large-scale battery storage, which remains expensive and logistically complex nearly everywhere.

The International Energy Agency has highlighted Uruguay’s management of variable renewables as a model worth studying closely. Few countries have achieved this kind of stability at a national scale while relying so heavily on sources that fluctuate with weather.

A pragmatic economic decision, not a climate crusade

Uruguay’s leaders were not primarily motivated by climate pledges. They recognized that dependence on imported oil and gas left the economy exposed to volatile global prices. Renewables offered a concrete way out — cheaper over time, domestically controlled, and increasingly reliable.

That calculation proved correct. Energy costs stabilized. The grid became more resilient. Thousands of jobs were created in construction, maintenance, and operations across the renewable sector. International capital followed, attracted by a predictable regulatory environment that gave investors confidence to make long-term commitments.

The World Bank has noted Uruguay’s energy transition as a rare example of decarbonization driving genuine economic growth rather than constraining it. Clear rules, consistent enforcement, and durable policy signals accomplished what declarations alone rarely do.

This matters beyond Uruguay’s borders. The International Renewable Energy Agency documents how Uruguay’s framework influenced energy planning conversations across Latin America — proof that a mid-sized, middle-income country can reshape regional thinking.

What other countries can learn

Uruguay’s model did not require cutting-edge technology, massive subsidies, or natural endowments unavailable elsewhere. It required political consensus and a stable framework that gave investors reason to commit capital over many years.

That is a particularly relevant lesson for developing nations still heavily dependent on fossil fuel imports. Uruguay demonstrated that leapfrogging that dependency is not a theoretical possibility — it is something a real country actually did, on a real timeline, with real-world tools.

There are honest limits to the comparison. Uruguay’s geography — abundant rivers, steady wind corridors, a relatively small and concentrated population — provided natural advantages not every country shares. Replication requires adapting the model, not copying it wholesale. Scaling this approach to larger, more complex grids remains an open challenge.

Still, the global momentum documented by Our World in Data suggests Uruguay is not an outlier so much as a leading edge. Renewables now account for over 30% of global electricity generation, with projections pointing toward 45% by 2030 C.E. Uruguay’s story shows what the far end of that arc can look like when governance and economics align.

What comes next for Uruguay

The country is not stopping at electricity. Uruguay is now exploring green hydrogen production and the electrification of its transport sector — moves that would extend its low-carbon lead into harder-to-decarbonize parts of the economy.

A nation that transformed its power grid in a decade is now asking what the next decade could bring. For a country that treated clean energy as an economic strategy from the start, the answer is likely to stay ambitious.
