A SEGUNDA GUERRA DAS CORRENTES: UMA ABORDAGEM HOLÍSTICA PARA CASAS AUTOSSUFICIENTES E A DESVINCULAÇÃO DO SISTEMA INTERLIGADO NACIONAL

Abstract

This study investigates sustainable and autonomous energy methods. It explores how self-sufficient residences and innovative energy storage systems can reduce dependence on the National Interconnected System (SIN) and promote sustainability. The methodological approach encompasses qualitative and quantitative assessments, addressing case studies of on-grid photovoltaic systems in homes and commercial establishments, analyzing costs, financial returns, and environmental advantages. These systems were found to provide a return on investment in approximately three years, with considerable energy savings and a reduction in environmental impact. The results highlight the relevance of emerging technologies, such as high-efficiency batteries and microgrids, in driving energy decentralization. Innovative proposals, such as the creation of green condominiums and rapid battery replacement systems for electric cars, were discussed as ways to improve the resilience and sustainability of the current energy model. The conclusion is that the transition to self-sufficient housing, combined with the use of renewable energy, can not only mitigate climate effects but also offer economic and practical alternatives for the sustainable progress of society. The research also highlights the importance of government policies and investments in infrastructure to enable this energy transition.
