A transparent and secure renewable energy exchange system that directly connects consumers with producers: this is the system developed by UrbanChain. The advantages of this direct exchange, also referred to as "Peer-To-Peer Exchange", are innumerable: for the final consumer, it translates into savings of up to 50% on their energy bills; for the producer, instead, it means greater profits over the medium to long term. Naturally, biogas energy producers are also among the producers.
