Where does a country’s electricity come from, and who can get it?
Cook Islands is placed 67th of 193 countries on energy in the Country Index 2026, from 2 of its 3 key statistics. Readings behind it: Carbon Intensity of Electricity 350 (2024); Renewable Share of Electricity Generation 50 (2024).

Placed from 2 of 3 key statistics
Not placed in the Country Index 2026 overall: measured on too few topics.
01The evidence
Only these place Cook Islands on energy — one vote each. Every value is the publisher’s own, read at the edition the Country Index 2026 used; the grey ticks are every other country it was compared with, lowest on the left.
Key 1 of 3
Ember
Why it is a key: How much greenhouse gas a country's power stations emit for every unit of electricity they produce.

Carbon intensity (gCO₂e per kWh generated)
Lower is better
Cook Islands: 350. Across the 193 countries in this edition, values run from 23.49 (Ethiopia) to 1,306 (Turkmenistan); the world median is 468.81.
Each grey tick is one of 193 countries in the 2024 edition.

Why it is a key: How much of the electricity a country generates already comes from renewable sources.

Higher is better
Cook Islands: 50. Across the 193 countries in this edition, values run from 0 (Gambia) to 100 (Paraguay); the world median is 31.14.
Each grey tick is one of 193 countries in the 2024 edition.
Key 3 of 3
World Energy Council
Why it is a key: How a country's energy system balances security of supply, affordability and environmental impact — three pressures that trade off against one another.

Trilemma score (0–100)
Higher is better
World Energy Council publishes no 2023 figure for Cook Islands, so the standing rests on the other keys.
Across the 126 countries in this edition, values run from 27.7 (Niger) to 83.2 (Denmark); the world median is 63.8.
Each grey tick is one of 126 countries in the 2023 edition.
02Over time
Each key’s published value, edition by edition, beside the world median. The Country Index 2026 is the first edition of the standing, so the standing itself has no history to chart yet.

03In context
A position reads best beside the countries around it. Every position below is a place among all 193 countries on energy, never a place within the region.
Cook Islands has no land border, so the table compares it with its sub-region. The standing is each country’s place among all 193 placed on the topic; the other columns are the publishers’ own values, read at the edition the standing used.

05Country Index 2026
Energy is Cook Islands’s 3rd best-placed topic of 4. Strongest first; each marker sits at the position divided by that topic’s field, so fields of different sizes compare fairly.
No standing on Governance & Institutions, Economy & Innovation, Work & Labour, Environment & Sustainability, Gender & Equality, Democracy & Civil Liberties, Peace & Security, Risk & Resilience, Mobility & Trade, Food & Agriculture, Poverty & Inequality, Digital & Technology: too few of those topics’ key statistics are published for this country.

07Questions
Every answer is built from the numbers on this page, so none can say something the page does not.
Cook Islands is placed 67th of 193 countries on Energy in the Country Index 2026, from 2 of its 3 key statistics (Carbon Intensity of Electricity and Renewable Share of Electricity Generation). The position is this site’s ordering of published statistics, not a rank any publisher printed.
350 in 2024 (carbon intensity (gCO₂e per kWh generated)), according to Ember. The world median in the same edition was 468.81.
50 in 2024 (renewables (% of electricity generated)), according to Ember. The world median in the same edition was 31.14.
Carbon Intensity of Electricity fell from 666.67 in 2000 to 350 in 2024; Renewable Share of Electricity Generation rose from 0 in 2000 to 50 in 2024.
No current reading is published for Cook Islands on Access to Electricity, Energy Intensity of GDP (PPP), Primary Energy Consumption per Capita, RISE Energy Efficiency Policy Score, RISE Renewable Energy Policy Score and World Energy Trilemma Index. They are listed rather than hidden, so the evidence on the page can be checked against it.

09Method
What this topic does not measure
This is deliberately the electricity and energy-system subject, not an infrastructure one: roads, railways, ports, water and telecommunications would each need a global series this site does not hold. Emissions are under Environment & Sustainability. Access to electricity is published here in full but takes no part in any ranking — more than half the world’s countries now report 100%, and a position derived from that would read “1, 1, 1 … 123”, which is noise rather than information.
A standing is a place in a list, not a mark out of anything. This one is part of the Country Index 2026, and it is worked out like this.
The other 5 statistics on this page come from 2 publishers, each named beside its numbers, with every edition and licence on the datasets pages.
