Ensuring the energy security is currently one of the EU’s top priorities. The EU energy policy, after the entry into force of the Treaty of Lisbon, is regulated by Article 194 TFEU, which guarantees a solid legal basis for European Union actions in this area on the basis of the Community method. The European Parliament, within the scope of its Community competences, as a participant in the decision-making process, contributes to shaping the face of the EU energy policy. Furthermore, by adopting nonlegislative resolutions, the EP expresses its position on the most crucial issues included in this policy and has an indirect influence on its shape. The aim of this article is the analysis of the content of these resolutions and presentation of the EP’s opinion on the challenges facing the EU in the field of energy. It should be highlighted that the European Parliament is the EU body with a strong emphasis on a supranational approach to energy security. The European Parliament prefers the view that all Member States, in a spirit of solidarity, must take actions to guarantee the EU’s common energy security. In favour of a common, integrated European energy market, the EP puts great emphasis on the necessity to implement ambitious climate policy objectives within its framework, the key element of which is the reduction of greenhouse gas emissions.
