The current state of international legal regulation of relations in the sphere of renewable energy is considered. The need to analyse the dynamics of the formation of states regulations which are enshrined in various sources, including those in Art. 38 of the Charter of the International Court of Justice, and others, which in international law has been called “soft law” is justified. It is shown that the countries of the world strive for cooperation within the framework of specialized international organisations designed to promote the implementation of RES production, but the advisory nature of these international organizations does not contribute to the revival of such cooperation. The main attention is focused on the activities of IRENA. The legal acts that regulate the activities of International organizations are analyzed. In legal doctrine, they primarily include international agreements, the main of which is the founding agreements, as well as headquarters agreements and agreements on such special issues as privileges and immunities, the procedure for concluding agreements, etc. It is noted that an important group of documents is acts of internal law of the organization, mainly acts adopted by the organization itself (decisions of its bodies), and the sources of international law are customs, court decisions, unilateral acts of states, etc. The need to supplement this list of sources with interstate political agreements, agreements on cooperation with international intergovernmental and non-governmental organizations, and some others is emphasised. It is noted that the legal status and activities of intergovernmental and non-governmental international organisations, including IRENA, are regulated by a complex of various international acts of a legal and non-legal nature. Multilateral treaties and conventions, resolutions of intergovernmental organizations, as well as acts of international organizations themselves form a system of norms designed to regulate the activities and legal status of international organizations. The legal nature and legal status of any international organisation are largely determined by its founding agreement, which serves as the legal basis for the creation and functioning of the organization. The regulation of the following issues by the statute has been analyzed, particularly the rights and obligations of member states, conditions and procedure for acquiring membership, termination and suspension of membership, structure of the organization, principles of adoption and legal nature of decisions, privileges and immunities of the organisation and its members, regulations on the headquarter, the principles of financing the activities of the organization and individual projects, general provisions on the procedure for the acquisition of legal force by the agreement, as well as the introduction of changes and additions to it, the official languages of the organisation and the depository. It is shown that, according to the charter, IRENA actively cooperates with the states, concludes special agreements with the relevant states regarding cooperation on projects. In addition, unlike other agreements with states, according to the statute, these agreements do not expire even after the termination of a state's membership in IRENA. As stated in Article XV of the statute, “withdrawal of a member from IRENA shall not affect its contractual obligations under Article V, Clause B.” It is shown that the structure of IRENA's central bodies is quite typical, as in many international organisations, it includes three main bodies: ruling, executive and administrative. These bodies, as a rule, are defined in the Charter and are considered the most important and mandatory in the structure of any organisation. And the IRENA Charter was no exception. The structure of the bodies of this international organisation is defined in paragraph A, Art. VIII, which is called “Organs”. In particular, it stipulates: “The main bodies of IRENA are established by this Statue: 1) the Assembly; 2) Council, and 3) Secretariat.” IRENA, like most international organizations functioning nowadays, has international legal status. The scope of such legal status is generally identical to the legal status of other international organizations, particularly specialized UN agencies.
