This week we are Planeteers because we are going to chat about renewable energy technologies. You see, generating electricity from renewable energy rather than fossil fuels offers significant public health benefits. But there are barriers. This chicken-and-egg problem is especially difficult with technologies that have long lives. Enter...PowerLedger. They allow renewable energy asset owners to decide who they want to sell their surplus energy to and at what price. Using blockchain technology, they provide a transparent, auditable and automated market trading and clearing mechanism for the benefit of producers and consumers.
