In 2022, Guam's electricity consumption was predominantly reliant on fossil fuels, with these sources contributing over 90% of the total electricity produced. The island's low-carbon energy production was nearly 8%, with solar energy accounting for the entire share of clean power sources. While this modest adoption of solar reflects Guam's potential to tap into sustainable and environmentally friendly electricity, the reliance on fossil fuels still constitutes a significant barrier to further reducing carbon emissions and improving air quality. Transitioning to low-carbon electricity sources can aid in combating the harmful effects of climate change associated with high fossil fuel use.

Is Electricity Growing in Guam?

Despite the high dependence on fossil fuels, recent trends indicate that electricity consumption in Guam is on a decline. The total electricity consumption per person was approximately 10,900 kWh in 2022, a drop of about 1,200 kWh/person compared to the year 2000. On a positive note, the island has seen an increase in low-carbon electricity generation, especially solar, reaching 848 kWh/person, which is substantially higher than the previous high recorded in 2019. This shift highlights an emerging awareness and capacity for growth in solar power generation, although it still contributes a relatively small share to the total energy mix.

Suggestions

To enhance its low-carbon electricity generation, Guam can draw lessons from regions where solar and nuclear energy have been successfully integrated into the power supply. For instance, Nevada and California have made remarkable strides in solar energy, contributing 34% and 31% of their electricity, respectively. Countries like France and Slovakia showcase the vast potential of nuclear energy, with nuclear contributing more than 65% of electricity in those areas. By investing in infrastructure and policies that support solar and nuclear development, Guam can similarly increase its clean energy share, reducing its reliance on fossil fuels and paving the way for an environmentally sustainable future.

History

Looking back at Guam's low-carbon electricity history, solar energy had been stagnant from 2015 to 2021, with no noticeable increases during those years. It wasn't until 2022 that there was a prominent shift, with solar energy showing a positive change of 0.1 TWh. This shift marks a critical turning point and an initial step towards embracing more sustainable electricity generation. As Guam moves forward, these strides should be built upon, aiming to accelerate the growth of low-carbon sources to ensure a greener and more sustainable energy future for the island.
