The trading of energy is done through a secure platform, often using a technology like blockchain. Blockchain is a database technology that processes and stores information, such as transactions of assets. These assets can be in the form of renewable energy credits, which can be traded through the database. Peer-to-peer energy trading platforms such as blockchain will allow consumers to share their excess energy amongst one another and control how it’s distributed through microgrids. Users who both sell and consume energy are called ‘prosumers’. Even if you don’t have solar panels, you can still purchase energy from others.
