The undoubtable need to implement circular production models requires a correct evaluation of the reliability and results of this implementation. For this, measurable, comparable and relevant indicators are needed that would take into account the multitude of aspects involved in the process. The purpose of this study was to identify and measure the circularity indicators of the energy sector in the Republic of Moldova and to compare these indicators with the average level of the European Union. To achieve the research objectives, the method of grouping indicators under technical, economic, social and environmental aspects was used. At the same time, the statistical data of international organizations (AIEA, OECD, AEE) regarding energy indicators at the global level were used. The research demonstrated that in the Republic of Moldova, the energy sector requires efficiency and a wide implementation of renewable technologies. These objectives can be achieved through investments, effective support mechanisms from the state, promotion of energy consumption reduction and demand management. This study was developed within the State Program 20.80009.0807.22 Development of the mechanism of formation of the circular economy in the Republic of Moldova.
