The pressing concern over greenhouse gas emissions has spurred the adoption of renewable energy, yet challenges persist, including the installation of microgrids for energy trading. Peer-to-peer (P2P) energy trading has emerged as a solution, but ensuring its security and transparency remains a challenge. To address this, blockchain technology is proposed. This study introduces a mobile app-based blockchain system to track electricity energy transactions in real time. It monitors power generation, load, and financial aspects, offering a secure environment for energy trading. By leveraging blockchain, direct energy trading between renewable energy providers and customers is facilitated, promoting energy decentralization. This innovative approach underscores the potential of renewable energy and blockchain technology in reshaping the energy sector. For further details, visit here.
