Systems, devices and methods for tracking authenticated clean energy with blockchains

Systems, devices and methods for managing a preferred energy supply chain are provided. A system including a specialized hardware- and software-based control system with access to a network including one or more distributed ledger(s) authorizes one or more energy distribution entity(ies) to reserve future right(s) to preferred energy for distribution to customers using new forms of promissory tokens (e.g., reserved preferred energy tokens). The system includes a secure metering device with a crypto-processor, holding an asymmetric cryptography key pair associated with preferred energy production hardware. The device is physically attached or integrated with the production hardware, and exclusively holds a unique private key of the asymmetric cryptography key pair, while publishing only the public key of the key pair through the network. The system authenticates production of, and transactions in, clean energy using new forms of smart contracts between buyers and sellers, with the aid of a governance body.
