Worldwide, global warming has become a major issue for humanity. The increased use of fossil fuel linked to human activities contributes to the emission of greenhouse gases in the atmosphere. Many governments have decided to turn to cleaner energy sources, commonly known as renewable energy. These energies come from natural sources, which are available, sustainable and great alternatives to fossil energy. As a result, different types of renewable energy have been aggressively developed and used. Despite this keen interest in renewable energy, only a small percentage of the world’s total energy production is generated from renewable sources compared to fossil fuels. By opting for renewable energy, government leaders have embarked on the path of energy transition, with the prospect of integrating the goal of sustainable development for environmental protection. While some countries have a head start regarding energy transition, others, such as the Caribbean region, are struggling to replace diesel or fuel oil with renewable energy, which include geothermal power. Many years ago, the volcanic islands were the subject of numerous geological studies to assess their geothermal potential. Although the results obtained showed great potential, the development of geothermal energy has been a slow process, prolonging the continued use of imported fossil fuel. Firstly, we will analyze hindrances to this transition. Secondly, we will draw attention to different geothermal projects in the region.
