Researchers at the Universidade Federal da Paraíba (UFPB) developed an innovative model that links solar power generation in vulnerable communities to the creation of local digital currencies operated by community banks and enabled by blockchain technology. The initiative transforms photovoltaic plants installed in these territories into assets that not only provide electricity but also generate direct economic value within the community. Energy produced by the solar systems is converted into digital credits that fuel a social currency, which can be used for local transactions, service payments, or accessing credit, creating an ecosystem where distributed energy generation directly connects to local economic dynamics. The project leverages blockchain to record and validate transactions in a decentralized, transparent, and secure manner, enabling traceable and auditable conversion of generated energy into monetary units while automating currency issuance based on energy production to reduce operational costs and enhance system reliability. Aligned with the concept of just energy transition, the initiative directs the benefits of renewable generation to populations in vulnerable situations, positioning solar energy not just as an environmental solution but as a tool for socioeconomic development.
