[en] This report notably addresses the issues present in a bill project and concerning the introduction of a progressive energy pricing with the implementation of a bonus-malus principle in energy tariffs as well as some measures related to social tariffs. After having evoked this progressive pricing which aims at promoting a more moderate use of energy, the author refers to international examples (California, Italy, Minnesota, Japan, Quebec, South Korea, Belgium and Germany). He outlines that such a progressive pricing incites a reduction of energy consumption. He discusses the required accompanying policies: struggle against energy precariousness and promotion of energy performance. Other accompanying measures are presented and discussed which notably concerns wind farm implantation. Then, the report contains the text proposed to the Senate, the opinion of the Commission, a list of hearings, and a table comparing the present situation, the content of the bill project, the text adopted by the National Assembly, and the text issued by the Commission
