RESUMO No contexto das mudanças climáticas, iniciativas voltadas à adaptação e à mitigação e que também reduzam as vulnerabilidades são um desafio crescente. A transição energética emerge com força nas agendas de políticas climáticas. O presente artigo aborda tal desafio a partir da análise da evolução dos instrumentos de proteção social e apresenta uma proposta de integração de políticas públicas de enfrentamento da pobreza e desenvolvimento sustentável, fundado na proteção socioambiental. A proposta tem como foco as condições sociais e ecológicas do semiárido brasileiro, onde as secas são um fator limitante à economia e ao bem-estar social. O sol abundante passa de problema a solução, ao ser aproveitado na geração de energia limpa, que gera renda real para comunidades vulneráveis.

This article presents the modeling of a solar photovoltaic system connected to the grid in rural low-income communities living in the semiarid region of Brazil. The model is based on the premise that enough electrical energy will be generated locally to meet the household demand for electricity and to produce a surplus that can be sold on the grid. The main idea is that the sun, usually associated with severe droughts in the Brazilian semiarid region, can be transformed into social income while fostering energy autonomy. To model the system, the computational tools Photovoltaic Software (PVSyst7.3.1) and System Advisor Model (SAM) were used. Several configurations (cases) of systems were analyzed and associated with the evaluation of three commercial electricity scenarios, considering the local electricity rate (USD/kWh). A case study was conducted in the rural settlement of Jacaré-Curituba in the Brazilian semiarid region, where different estimated sale prices for the energy surplus were compared with traditional monthly cash transfers to poor families from the social welfare program “Bolsa Família”. The results indicate the viability of this model as an income alternative for low-income communities.

Imagination is more important than knowledge. For knowledge is limited to all we now know and understand, while imagination embraces the entire world, and all there ever will be to know and understand.
