Abstract<\/strong><\/p>\n\n\n\n The study aims to assess the alternatives to the diversification of energy carriers in the ASEAN member countries in the context of minimizing the risks associated with the creation of an energy portfolio. To determine the level of diversification of energy carriers, the indicator of the diversification of the energy carriers of the country based on the Shannon-Wiener index is used. In order to identify possible changes in the energy market of the ASEAN member countries, three scenarios are proposed based on an increase in the share of renewable energy sources. The analysis of the energy production in the ASEAN member countries showed that Indonesia is the leader in the production of energy from traditional energy sources and Thailand has the most developed energy production from renewable energy sources. According to the two developed scenarios for increasing the share of renewable energy sources, there is an increase in the level of diversification of the energy sector in all countries considered. The assessment of possible deviations from the expected results according to the described scenarios for an increase in the share of renewable energy sources made it possible to single out countries affected by positive and negative deviations. <\/p>\n\n\n\n
