Energy security score

55out of 100

Moderate. Puerto Rico ranks 113th of 158 countries and 22nd 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 Puerto Rico, 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, oil and other fossil fuels, made 49%.	73
Little reliance on imported power Puerto Rico exported more electricity than it imported, so it scores full marks.	100
Low-carbon power Nuclear and renewables made 6.3% of generation.	6
Low gas and oil use Gas and oil made 78% of generation; the score is 100 minus that share.	22

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