Abstract
This study critically examines the dynamics of energy demand and its environmental implications within the Dominican Republic's energy sector, using the MARIO model for a comprehensive multisectoral analysis. Key findings indicate that despite the integration of renewable energy sources, the surge in energy demand under the Business As Usual (BAU) scenario leads to a significant increase in greenhouse gas emissions. This underscores the urgent need for enhanced energy efficiency and the implementation of robust decarbonization strategies across all sectors to mitigate the adverse effects of rising demand.
