Subject. The article considers issues of energy security in Russia. Objectives. The aim is to compare Russia with other countries in terms of energy security. Methods. To calculate the level of energy security, we applied the fuzzy logic method, enabling to evaluate both qualitative and quantitative variables. Results. The study revealed that the level of energy security of Russia is 0.557. This indicator is between the subset of "energy security level above average" and the subset of "average energy security level". In general, the level of energy security in the countries with the highest index of sustainable development is above average. Among the countries with the highest index of sustainable development, according to the results of 2019, Denmark has the highest level of energy security. Conclusions. The level of energy security of Russia turned out to be lower as contrasted with the studied countries. It is important to develop recommendations for improving the level of energy security based on foreign experience.
Keywords: energy security, fuzzy logic, sustainable development goal
