Electricity in Guam in 2022
In 2022, the electricity consumption in Guam was overwhelmingly dominated by fossil fuels, accounting for more than 90% of the total electricity generated on the island. Low-carbon energy, specifically solar power, contributed a small portion of just under 8% of the electricity generation. This minimal share of clean energy highlights a significant opportunity for Guam to diversify its energy mix and embrace more sustainable energy sources. This situation leaves much room for improvement, particularly in increasing the share of clean energy sources to reduce dependency on fossil fuels, which are responsible for air pollution and contribute to climate change.

Is Electricity Growing in Guam?
Despite the pressing need for clean energy growth, electricity consumption in Guam has seen a decline when considering long-term trends. The per capita consumption of electricity was 10,900 kWh in 2022, marking a reduction from the previous record-high of 12,123 kWh set in the year 2000. This represents a decrease of 1,223 kWh per person. On a more positive note, however, Guam has made strides in low-carbon electricity generation. The recent solar output, set at 848 kWh per capita in 2022, demonstrates an increase of 353 kWh per person compared to the previous record in 2019. These gains in solar electricity highlight Guam's capacity for growth in clean energy despite the overall decline in electricity consumption.
Suggestions
To expand low-carbon electricity generation, Guam can look to successful regions like Nevada and California, which significantly utilize solar power, offering frameworks for scale and efficiency. Nevada generates about 34% of its electricity from solar energy, serving as a testament to the potential for solar power to play a major role in regions with abundant sunlight, like Guam. Additionally, the example of nuclear energy in countries like France, where nuclear power constitutes 67% of the electricity mix, can provide another avenue for Guam's transition to low-carbon power. By investing in both solar and nuclear energy, Guam can create a more sustainable and secure electricity system, reducing its reliance on fossil fuels and enhancing its energy independence.
History
Historically, low-carbon electricity generation in Guam has been slow to progress until recent years. For the majority of the 2010s, from 2015 to 2021, solar power generation remained stagnant, showing no incremental growth annually. However, 2022 marked the beginning of a positive change, with an increase of 0.1 TWh in solar electricity generation. This shift signals the potential for further expansion and serves as an essential stepping stone for Guam to boost its clean energy capacity. Investing in solar and perhaps exploring nuclear options could guide Guam towards a cleaner, more adaptable energy future, crucial for meeting forthcoming energy demands and ensuring environmental sustainability.
