Renewable Energy Consumption: Guam

Analysis# Guam Renewable Energy Consumption Guam's renewable energy consumption reached 6.7% of total energy in 2022, matching its all-time peak and representing a dramatic shift from the 0.4% recorded in 1993. Over the 32-year span from 1990 to 2022, renewable energy consumption grew 1,240%, reflecting sustained investment in clean energy infrastructure despite the territory's geographic isolation and reliance on imported fossil fuels. The most significant acceleration occurred between 2014 and 2016, when renewable consumption jumped from 0.7% to 4.4%—a sixfold increase in just two years. Since 2016, growth has moderated but remained steady, with consumption hovering between 4.5% and 6.7%. The 2022 peak suggests Guam has solidified its renewable energy foundation, though the 6.7% figure indicates substantial room for further expansion toward higher sustainability targets.
