In this work is in concise form shown the development of European Union law in the sphere of energy. The major accent was placed on the genesis of the development of primary EU law in this area and basics which it is set, in purpose of a better understanding of contemporary processes in the energy sector on the European continent. Particularly attention is given to the issues of the regulation of energy sector under the EU’s founding treaties, as well as issues of common European energy policy. In addition, an important place is taken by considerations related to the development of the EU aquis communautaire in this fled, with particular accent to the analysis of “First energy package”, as a kind of basis for the modern instruments of legal regulation of the energy sector in the EU.

Osnovni akcenat je stavljen ne genezu razvoja primarnog prava EU u ovoj oblasti i osnovama koje je ono postavilo, u cilju boljeg razumevanja savremenih procesa u oblasti energetike na evropskom kontinentu.

Pored toga, važno mesto zauzimaju i razmatranja, vezana za osnove razvoja sekudarnog prava EU u predmetnoj oblasti, pri čemu je poseban akcenat dat analizi „Prvog energetskog paketa EU“, kao svojevrsne osnove potonjeg i savremenog instrumentarija pravnog regulisanja energetike u EU. Sva pitanja o kojima se raspravlja u radu, posmatrana su kroz prizmu, trenutno najaktuelnijih pitanja energetike, izgradnje međunarodnih infrastrukturnih objekata namenjenih transport energenata
