Argentina
ARGArgentina is first in Latin America and the Caribbean for nuclear.
Nuclear supplies 7% of its electricity.
What this grid depends on
Three measures that say more about a country than how much power it makes. Open “what this means” on any of them if the term is new.
Cleaner than 6 in 10 grids worldwide.
What this means
How much planet-warming gas is released to make one unit of electricity. Two countries can generate exactly the same amount and one of them be ten times dirtier doing it. Lower is better.
Argentina buys in more electricity than it sends out.
What this means
The share of the electricity used here that was generated abroad and carried in over high-voltage lines. The higher it climbs, the more this country relies on a neighbour to keep its lights on.
Most of what this grid runs on is produced at home.
What this means
How much of what this grid runs on the country can supply itself. Sun, wind and water count fully, because nobody can cut them off; coal, gas and oil only as far as the country digs them up. A high score is not the same as a good grid: mining your own coal scores well, importing uranium scores badly.
Also true of Argentina
Argentina is third in Latin America and the Caribbean for how much electricity it makes.
153 TWh a year.

Figures are for 2025, the most recent year reported for Argentina. Generation shares are a percentage of electricity generated, not of energy used. How this is calculated.
