Energy security score

70out of 100

Strong. New Caledonia ranks 63rd of 158 countries and 4th of 6 in Oceania. 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 New Caledonia, 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, coal, made 37%.	78
Little reliance on imported power New Caledonia exported more electricity than it imported, so it scores full marks.	100
Low-carbon power Nuclear and renewables made 27% of generation.	27
Low gas and oil use Gas and oil made 37% of generation; the score is 100 minus that share.	64

The five measures are weighted 30%, 20%, 20%, 15% and 15%. How the score works.
