High energy costs and fossil fuel dependency contribute to dampening Caribbean competitiveness and potential growth. In this scenario, energy efficiency has the potential to reduce energy consumption, ensure an adequate supply of energy, increase energy security, reduce negative environmental impacts and, at the global level, reduce emissions of greenhouse gases. However, it is important to have a clear understanding of macro energy sector conditions before implementing energy efficiency policies. In this study, we describe and compare energy efficiency trends in four countries in the Caribbean subregion: Barbados, Guyana, Saint Lucia and Trinidad and Tobago. The report is based on data and indicators prepared for the Energy Efficiency Indicator Database (BIEE) project, carried out by the Natural Resources Division of the Economic Commission for Latin America and the Caribbean (ECLAC) under the umbrella of the Regional Observatory on Sustainable Energies, and in close cooperation with the French Environment and Energy Management Agency (ADEME).
