The World Bank estimates that approximately 1.2 billion people in the world still live without electricity. The UNs Sustainable Development Goals (SDG) seek to provide universal access to electricity services by 2030. In Brazil, with the implementation of social programs such as “Light for All,” access to electricity has been extended to more than 15 million people in recent years. However, many residential areas, mainly in the Brazilian Amazon, still lack access to the electricity supplies due to factors such as low population density, topography, long distances, lack of infrastructure, among others. This paper intends to elaborate and analyze hypothetical scenarios to investigate ways that allow planning and electrification strategies in the municipality of “São Gabriel da Cachoeira” located within the Brazilian Amazon. The OnSSET – a set of modeling tools based on QGIS – was applied with open access data. The aim was to identify an ideal combination of electrification options by considering network extensions, mini-grid and/or autonomous, solar, wind, hydroelectric and diesel solutions depending on the availability of resources. Our results show that photovoltaic solutions are the most adequate for the region, mainly because of the region’s high solar radiance, associated with low wind speeds and high diesel costs.

Poverty reduction is a complex global challenge where renewable energy emerges as a promising solution, particularly in resource-rich countries like Brazil. Renewable energy can enhance conditions in vulnerable communities without exacerbating climate change. This paper reviews the scientific literature on the role of renewable energy in alleviating energy poverty, focusing on Brazil and its global partnerships. Using the Web of Science database with the keywords poverty, renewable energy, and Brazil, this study analyzes 38 articles. The inclusion criteria were broad, focusing on the relationship between poverty in Brazil and renewable energy use. Keywords such as specific types of renewable energy (e.g., solar, wind) were excluded to avoid omitting important renewable sources. This review encompasses theoretical models, discourse analyses, case studies, and systematic reviews, addressing topics from rural electrification to socio-economic factors influencing sustainable energy adoption. Despite growing interest and international collaboration, research gaps remain, highlighting the need for increased academic engagement. The objective of this study is to address the existing gap in the literature concerning the impact of renewable energies on energy poverty in Brazil. Through a comprehensive review, this work maps current knowledge, identifies gaps, and highlights trends by integrating socio-economic analyses with technical assessments for a holistic perspective.

This article discusses the relationship between urban slums and the management of the urban infrastructure network (electrification). An extensive survey of the scientific literature on the subject points out the main challenges and possible solutions for fixing precarious electrical infrastructure in urban slums through the promotion of public policies and the establishment of new arrangements based on distributed generation technologies and smart grid. A dialogue was also developed involving topics such as sustainable development and electrification of slums; relationship between communities and modernization of electrification; and emerging and sustainable technologies in the context of urban slums. Thus, a design was constructed that triggered a discussion of the relationship between this work and several other works found in the literature. This research indicates the need to strengthen local governance and the participation of urban slums for the technological modernization of the local electrical network, mainly with the implementation of smart grid and photovoltaic generation systems.
