Electricity in Cook Islands in 2021

Global Ranking: #70
40.0% #84 Low-carbon electricity
335.20 watts #103 Generation / person
411.00 gCO2eq/kWh #95 Carbon Intensity

As of 2021, the Cook Islands present a peculiar scenario in terms of electricity consumption. There's a complete absence of low-carbon electricity generation in the grid, which includes nuclear, wind, and solar energies. This contrasts with the global scenario where, on average, individuals consume around 410 watts, with a significant portion coming from low-carbon sources. The lack of clean energy infrastructure not only places the Cook Islands behind in the sustainable energy transition, but may also negatively affect the islands' economy and environment. High dependency on fossil fuels can lead to price vulnerabilities and increased carbon emissions.


Looking at successful models from around the world, the Cook Islands might expand its existing solar energy efforts to increase low-carbon electricity generation. For instance, the People’s Republic of China and the United States, in 2021, generated over 500 and 240 TWh of solar electricity, respectively. While these nations are much larger, smaller nations have successful solar programs too; Japan and India generated 100 and 119 TWh, respectively. These figures signify the potential of solar energy, particularly for a sunny, island nation like the Cook Islands. With appropriate investment and planning, it’s feasible for the Cook Islands to drastically transform their energy landscape, mitigating environmental impacts while fostering economic diversification.


Historically, the landscape of low-carbon electricity in the Cook Islands has been stagnant. The data shows zero terawatt-hours (TWh) of solar electricity generated annually, from 2017 to 2021. This indicates that, so far, there has been no substantial effort to harness solar energy in the islands. There is a lack of data regarding wind or nuclear energy generation, but given the absence of significant industrial infrastructure, it may be inferred that the attempts have been negligible or non-existent. This lack of development in the low-carbon energy sector positions the Cook Islands farther behind in the global move towards cleaner, sustainable energy.
