This article aims to evaluate the relations between Central Asian countries and EU countries to ensure the functionality of the European Union energy policies in the context of energy security. The diversity of energy resources and market needs of Central Asia may be a way to meet the increasing energy needs of the European Union, especially after the Russia-Ukraine war. In the context of energy security, in the recent period, when a new, more global dimension of the policies followed by the democratic European institutions from the past has been implemented in foreign policy, it has been discussed that the energy resources of Central Asia can be used more efficiently to the regional and global interests and power of Europe and to reduce the dependency on a single country. The basic assumption in this article is that the current energy needs of the European Union should be discussed with the Central Asian countries to provide energy security, to reduce foreign dependency. Considering all these limitations and inferences, this article consists of three parts. The first part examines the energy potential and current opportunities of Central Asian countries are explained in the context of energy resources. In the last part, the place and importance of Central Asia in the energy policies of the European Union are justified, and some analyses and inferences about the importance of energy are made to improve the relations between the two regions.
