Electricity in Guam in 2022
In 2022, Guam's electricity consumption was overwhelmingly dependent on fossil fuels, which made up more than 90% of the total electricity generated. Conversely, the share of low-carbon or clean energy was low, at just under 8%, with solar accounting for all of it. This stark imbalance underscores Guam's heavy reliance on fossil-based energy, which poses significant challenges related to climate change and pollution. Given the pressing need for clean energy transitions worldwide, the current state of electricity consumption in Guam highlights a crucial area for improvement—supporting the expansion of sustainable energy sources like solar power to reduce its carbon footprint significantly.

Is Electricity Growing in Guam?
Comparing the latest data to the historical record reveals concerns about electricity growth in Guam. The current per-person electricity consumption stands at 10,900 kWh, which is more than 1,200 kWh less than the previous record set in 2000. This decline suggests that electricity consumption is not keeping pace with other nations or regions. However, a positive trend is evident in the growth of low-carbon electricity generation, particularly solar, which increased to 848 kWh per person from a previous record of 494 kWh in 2019. The increasing share of solar electricity is encouraging, yet further efforts are needed to ensure sustainable growth that can meet future energy needs while reducing reliance on fossil fuels.
Suggestions
To boost low-carbon electricity generation in Guam, it is advisable to draw lessons from regions effectively leveraging clean energy. For instance, Nevada and California have successfully integrated solar power to make up about 34% and 31% of their electricity, respectively. Similarly, countries like Denmark and states like Iowa demonstrate the potential of wind energy, while nations such as France and Slovakia highlight the effectiveness of nuclear power. By strategically adopting and expanding both solar and nuclear energy capabilities, Guam could significantly enhance its clean energy share. These strategies would not only contribute to a decrease in carbon emissions but also possibly stimulate economic growth through green energy investments and job creation.
History
The history of low-carbon electricity in Guam shows a slow, yet steady, transition primarily driven by solar power. From 2015 to 2021, solar energy witnessed no noticeable change in generation capacity, indicative of stagnation in expanding green energy infrastructure during that period. However, a positive shift occurred in 2022, with a modest increase of 0.1 TWh in solar energy generation, marking the beginning of a potentially positive trajectory toward diversified and clean electricity generation. This upward trend represents both a promising start and a call to action for continued investment and development in the realm of low-carbon electricity sources to safeguard Guam's energy future.
