The concept of Sustainable Development (SD) resonates throughout developing countries in order to link its key elements: the environment, society and the economy for the development of man’s well-being and stability. The goal for SD is to meet the needs of the present without compromising the ability of future generations to meet their own needs; a guarantee that is promised by energy services, production, availability and distribution. Sustainable Energy Development (SED), as the answer, is locked conceptually in the inclusion of all renewable sources and technology that can produce economic and safe energy resources for all without impacting the environment. Renewable energy sources are encouraged because they are replenishable within a human lifetime and causes no long-term damage to the environment; adequate technologies, on the other hand, are essential for energy security, improving energy efficiency, reducing dependence on fossil fuel resources, and providing opportunities for mitigating the emission of greenhouse gases. This thesis aims at analyzing the interrelationship between energy and the three dimensions of SD: social, economic and the environment. Itexplores the concept of SED in Belize, presenting the best assessment for the Nation through the utilization of Energy Indicators (EI) as a tool to measure SED. The end result should establish an idea of Belize’s ecological carrying capacity, energy-related environmental impacts, economic efficiency and socio-political equity.
