None Electricity imports

In 2021, the Cook Islands consumed 335.2 watts per person in electricity. More than half, precisely 201.12 watts of this, came from fossil energy, while the remaining portion, equal to approximately 134.08 watts per person, was generated from low-carbon sources, namely solar energy. Compared to the global average consumption of 412 watts/person, the Cook Islands' electricity consumption is quite low. This lower level of electricity generation can impact the Islands' ability to support industry growth and potentially hinder advancements in living standards. The Cook Islands stand on their own when it comes to electricity, as they don't import or export electricity from or to other countries or regions.


In regards to increasing their low-carbon electricity generation, the Cook Islands could consider expanding their existing solar energy facilities, given the region's abundant sunshine. Further inspiration could be taken from countries successfully harnessing wind energy, given the similar natural conditions present in the Islands. Denmark, Sweden, and Ireland, for instance, have successfully brought considerable amounts of wind electricity per person, generating 369, 363, and 258 watts/person respectively. Given the Cook Islands' similar geographical features, harnessing wind energy could become a significant part of the nation's low-carbon electricity generation.


Looking at the history of low-carbon electricity in the Cook Islands, there has been consistent solar electricity generation over the past five years. Each year from 2017 through 2021 has seen a steady state of solar electricity production, with no noticeable increases or decreases. Solar power has been the Islands' primary source of low-carbon electricity for at least half a decade. These historical trends suggest a solid foundation for solar power in the Cook Islands, but there is clearly potential for growth, especially considering the successes of other island and coastal nations in harnessing wind power.
