The growing environmental challenges and the urgent need for an accelerated energy transition have intensified the European Union’s efforts to expand the use of renewable energy sources and reduce dependence on fossil fuels. This study estimates the impact of selected socioeconomic, political, and technological factors on the share of renewable energy in gross final energy consumption. This issue is of key relevance for EU energy and climate policy, particularly in the context of the ongoing transformation processes in Central and Eastern European (CEE) Member States. The analysis covers eleven CEE countries—Poland, the Czech Republic, Slovakia, Hungary, Romania, Bulgaria, Lithuania, Latvia, Estonia, Croatia, and Slovenia—over the years 2004–2023. Using panel data models in both static (fixed effects) and dynamic specifications, the study identifies the determinants of renewable energy development and captures inertia effects. The results reveal strong links between energy security and renewable energy deployment, where the pursuit of greater self-sufficiency often slows the expansion of renewable energy. Countries with high greenhouse gas emissions also show limited incentives to accelerate renewable energy integration. Based on the findings, this study proposes policy recommendations aimed at enhancing energy efficiency, strengthening energy security, and supporting the long-term sustainable growth of renewable energy in the region.
