In this article, EU energy policies are discussed within the context of energy supply security, focusing firstly on how the general lines of the EU’s energy profile will unfold along with their strengths and weaknesses. It will then continue by discussing the historical process energy policies of the Union will be determined. In the following section, this article will attempt to ascertain the degree of energy supply security in the EU as well as examine the policies of the Union within the context of increasing security in energy supply.
