In 2022, the electricity consumption in the Cook Islands was evenly split between clean energy sources and fossil fuels. Specifically, all of the electricity classified as low-carbon was derived from solar power, accounting for half of the total electricity generation. This reflects a significant achievement in adopting clean energy technologies, as solar power alone was responsible for providing more than half of the country's low-carbon electricity. The remaining electricity was generated through fossil fuels, pointing towards a balance that the Cook Islands should aim to shift more towards low-carbon sources to combat climate change and reduce air pollution.
To further increase low-carbon electricity generation, the Cook Islands should consider expanding their existing solar power infrastructure. Learning from countries that successfully harness low-carbon energies, such as Denmark, which generates over half of its electricity from wind, could guide these efforts. While nuclear energy plays a significant role in countries like France and Slovakia, the Cook Islands could draw particularly from similarly sized island nations like Cape Verde, which achieves a notable portion of its electricity from wind. Transitioning towards other forms of low-carbon technologies besides solar may diversify the energy mix and increase resilience within the grid.
The history of solar power in the Cook Islands from 2017 to 2022 shows a stable yet unchanging landscape, as no additional electricity generation from solar was recorded during these years. This period represents a stagnation rather than growth in solar energy, and suggests that the Cook Islands have yet to capitalize on the vast potential of expanding low-carbon electricity infrastructure. Increasing solar generation or integrating complementary low-carbon sources like wind or exploring small-scale, modular nuclear options could effectively alter this trajectory, reducing dependence on fossil fuels and reinforcing the commitment to sustainable energy production.
