My research project is focused on unraveling the role of business in a sustainable energy transition, focusing on how heterogenous firms respond to societal, competitive, regulatory, and legislative pressures for a sustainable energy transition. The focal point is how trade-offs in terms of different types of sustainable technologies and alternative fuel sources, digitalisation, legal challenges driven by civil society, and citizen engagement for transformative change are impacting the energy transition and the relations among the involved actors, possibly making it more decentralised and regionalised.
