Uwagi na tle pojęcia „energii ze źródeł odnawialnych” w prawie Unii Europejskiej

The objective of Directive 2009/28/EC of the European Parliament and of the Council of 23 April 2009 (as well as its replacement Directive 2018/2001 of 11 December 2018) on the promotion of the use of energy from renewable sources, is to increase the use of renewable energy sources. The starting point for any further considerations in terms of issues regulated by those legal acts should be systematizing the terminology related to the concept of energy from renewable sources. It should be noted that these issues remain largely unexplored in greater death by literature. Therefore, the subject of this article is not only the analysis of how the concept of energy from renewable sources is defined in EU law, but also how this term is interpreted in the case law of the Court of Justice.
