Energy security score
Vulnerable. It is not ranked because its power system is very small. 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 the Cayman Islands, 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 96%. | 9 |
| Little reliance on imported power The Cayman Islands exported more electricity than it imported, so it scores full marks. | 100 |
| Low-carbon power Nuclear and renewables made 4.2% of generation. | 4 |
| Low gas and oil use Gas and oil made 96% of generation; the score is 100 minus that share. | 4 |
The five measures are weighted 30%, 20%, 20%, 15% and 15%. How the score works.
