At South Start 2019, I got to sit down in our podcasting tent and chat with Dr Jemma Green. We found out exactly how Jemma went from working mainstream finance in a bank to finding a passion in sustainability. Jemma is the executive chairman at Power Ledger where renewable energy is at the forefront of their mission. Through the utilisation of blockchain, Power Ledger have enabled peer-to-peer trading of excess solar electricity. We discuss the importance of disruptive innovation in terms of leading to big change and exactly how her tech works.With the current nature of the climate, looking towards sustainable methods is a rising importance. This is a great listen for anyone interested in making a change to solar energy or for those interested in Power Ledgers operations. Enjoy!
