Fundamental Duty to Sustainable Development in the Brazilian Federal Constitution of 1988 and Solar Energy (Sdg 7) as an Energy Policy in the Current Brazilian Conjuncture

Energy policies are in a moment of transition due to the emergence of the new energy system, based on a decentralized model and coming from renewable sources, which seeks energy self-sufficiency with energy production by the consumers themselves – prosumers. The Brazilian energy model is still heavily centralized and solar energy, an example of a decentralized model, represents only 1.4% of the national energy matrix. The article is divided into three topics, dealing with fundamental duties; sustainable development, green economy and accessible and clean energy matrix, in line with objective 7 of the 2030 Agenda; and solar energy as a renewable source in Brazil, demonstrating the challenges that the country faces to diversify its energy matrix, which is still very dependent on the hydraulic matrix
