The article is devoted to an urgent problem in the field of environmental safety – the legal regulation of renewable energy in Russia at the level of federal legislation, as well as trends in the field of program normative regulation in the context of long-term planning until 2050. The method of special normative regulation in the field of renewable energy chosen by the legislator is determined by the directions of state regulation in the area under consideration. The basis for long-term programmatic legal regulation is the combination of traditional and renewable energy, which is necessary for the country’s energy security. On the other hand, a serious problem of legal regulation has been identified: at the level of federal legislation, there is a legal gap in the issue of the relationship between the concepts of “energy resource” and “non-renewable energy sources”, which is the reason for finalizing the current legislation. The result of the study is recommendations to reflect in the legal regulation of renewable energy, which is programmatic and long-term in nature, not the principle of priority of renewable energy sources (RES), but the principle of combining traditional and renewable energy and its development, taking into account the interests of the country’s energy security. Thus, the actual preservation of the priority of traditional energy and the development of energy based on renewable energy sources within the framework of regulatory long-term planning based on state support determine the main direction of developing the country’s environmental safety system for the coming decades.
