This paper deals with how the “free” energy market works in Brazil and around the world in relation to the means of energy production used, seeking to show how the environment that defines the energy market adjusts to the evolution of energy generation technology and vice versa. The aim is to synthesize an understanding of the current energy commercialization scenario and present the main technological aspects of each means of energy generation to develop tools or paths to improve the performance of systems and machines belonging to the electrical area, thus making a scientific contribution to the Generation, Transmission, and Distribution of Electric Energy—GTD market. It is a fact that global energy demand has increased, and due to the high emission of gases that contribute to global warming in the energy generation process, it is necessary for renewable energy generation to increase to the detriment of the reduction in thermoelectric power plants. In this sense, there is a need to understand the regulatory requirements of the market for the distribution of renewable energy, its challenges and opportunities, and the influence of consumers on this distribution. This way, 10 base articles were chosen through a systematic literature review and visiting the regulatory framework in different countries (developed and developing). The aim was to synthesize the studied themes and topics, focusing on the differences between the regulatory requirements for wind and solar distribution and onshore and offshore wind. It was possible to notice that developed countries have an excellent energy transmission and distribution infrastructure, initially focusing on the quality of supply and later on energy policies to promote renewable sources. Thus, even if the energy matrix is mainly renewable, it is necessary to diversify it, as in the United States, invest in delivering quality to consumers, and then implement policies to promote renewables.
