The energy system is undergoing a fundamental transformation – from fossil to renewable energy, from central power plants to distributed, decentralised generation facilities such as rooftop solar panels or wind parks, from utilities to private residents as producers of energy, and from analogue to digital. This book looks at the energy transformation from two complementary angles: governance and business model innovation. On the one side, governance is a decisive factor for the success of the transformation because it can act as an accelerator, or it can delay the process. On the other side, entrepreneurs and corporate decision-makers provide new business models for a decentralised energy world. Based on best practices, country studies and interviews with CEOs and founders of startups from all over the world, the "Global Game Changer" suggests eight key principles for political decision-makers to successfully implement the transformation, and six core competencies for corporate decision-makers to thrive in the new marketplace.
