The significance of clean energy, education, and environmental management in fostering a sustainable future

Abstract

BACKGROUND AND OBJECTIVES: In Santa Cruz del Islote, an island located in the Colombian Caribbean, the lack of access to reliable electricity significantly affects the quality of life and educational opportunities of its inhabitants. The ongoing dependence on diesel generatorpowered polygeneration systems is financially unsustainable, detrimental to the environment, and unstable in operation. The island experiences an average energy autonomy of only 11 hours. Consequently, this study intends to assess the viability of introducing renewable energy systems, particularly solar and wind energy, designed to suit the island’s specific climatic and geographic characteristics, with the objective of boosting energy self-sufficiency and encouraging equitable educational access METHODS: The study focused on the assessment of meteorological and energy data obtained from Santa Cruz del Islote to evaluate the viability of solar and wind energy. Solar irradiance levels were evaluated using historical data and the application of atmospheric transmittance models. Another approach to understanding wind behavior involved examining historical meteorological data, developing wind rose diagrams, performing frequency analysis, and utilizing probability density functions. The study also included an assessment of the island’s available renewable energy resources. FINDINGS: The results indicate that Santa Cruz del Islote receives high levels of solar irradiance throughout the year, with average daily values around 4,290 and peak values exceeding 5,780 watt-hours per square meter. The wind behavior analysis revealed predominant directions toward the north and north-northeast, with average wind speeds ranging from 2.6 to 4.7 meters per second, suggesting the feasibility of harnessing this available renewable resource. Wind energy potential, however, changes with the seasons, experiencing diminished availability between May to November. These findings support the design of hybrid renewable energy systems tailored to local conditions. CONCLUSION: The findings demonstrate that Santa Cruz del Islote is equipped with enough renewable energy resources to enable a move away from fossil fuels. Implementing clean energy technologies would not only reduce environmental impact and operational costs but also enhance educational infrastructure and digital access. The merging of sustainable practices, technological progress, and social fairness is vital for the enduring resilience and advancement of insular communities including Santa Cruz del Islote.
