Global GridUruguay's energy mix and electricity
🇺🇾 In 2025, Uruguay generated 11.9 TWh of electricity. The largest source was wind at 41%, followed by hydro (27%) and bioenergy (25%). In total, 98% came from low-carbon sources (nuclear and renewables) and 2.2% from fossil fuels.
On average, each kilowatt hour produced about 80 grams of carbon dioxide (CO₂), far below the world average of 458 grams in 2025. That makes Uruguay the 17th cleanest of 158 countries that generate at least 1 TWh a year.
Electricity demand was 14.8 TWh. Uruguay imported 2.81 TWh more electricity than it exported, equal to 19% of its demand.
Since 2000, electricity generation has grown by 57%, from 7.59 TWh. The low-carbon share went from 94% to 98%. The biggest rise was in wind, from 0% to 41% of generation. The biggest fall was in hydro, from 93% to 27%. Carbon intensity rose from 67 to 80 grams per kWh.

Energy security score
Strong. Uruguay ranks 15th of 158 countries and 9th of 29 in Americas. The score shows how well a country could keep electricity affordable and on if fuel supplies were disrupted. It is based on 4 of the 5 measures.
| Measure | Score |
|---|---|
| Produces its own energy No reliable figure exists for Uruguay, so this measure is left out and the other four count for more. | n/a |
| Variety of power sources How evenly generation is spread across nine sources. The largest, wind, made 41%. | 78 |
| Little reliance on imported power Net imports were 19% of demand; each 1% takes off 2 points. | 62 |
| Low-carbon power Nuclear and renewables made 98% of generation. | 98 |
| Low gas and oil use Gas and oil made 2.2% of generation; the score is 100 minus that share. | 98 |
The five measures are weighted 30%, 20%, 20%, 15% and 15%. How the score works.
Oil and gas pipelines
Global Energy Monitor lists 548 km of oil and gas pipelines operating in Uruguay, 0 km being built and 809 km proposed (lengths measured along the mapped routes; a pipeline crossing borders counts in full for each country).
