Chris Adams is joined by special guest Dr. Tom Brown from TU Berlin to explore how modelling can help build a fossil free internet and power grid. They discuss Google's 24/7 carbon free energy goals, the growing impact of data centres on electricity systems, and how investments in clean energy technologies could accelerate global decarbonisation. Along the way, Tom shares why open source energy modelling is helping shape a more transparent and sustainable energy future.
