Abstract
The EU is now considered as an actor in international relations in many ways. Considering that it is dependent on energy imports, it is interesting to watch the actorness of the EU in energy relations as well.
In this article, the external actorness of the EU in its energy relations is analysed and specified based on a set of predefined criteria of a modified concept: (i) the diplomatic apparatus and policy tools the actor uses in its energy relations; (ii) the consistency and specificity of the external energy policy and the goals and interests pursued by the EU in regard to it, and (iii) the actor's perception of a third party which is accepted and recognised as an autonomous actor in the energy field by other actors. The criteria are then applied to a case study focused on Algeria in order to demonstrate whether the EU can be considered as an actor.
