In this episode, our guest is Mike Westerman, who leads the hydropower team at GHD, a global consultancy with deep expertise in water, dams, and geotech. Mike shares fascinating insights on the evolution of hydropower—from its origins at Niagara Falls to today’s high-efficiency, computer-modeled turbines. He explains why pumped hydro remains the dominant form of energy storage globally and how it's now essential for supporting low-cost solar. Mike also explores the challenges of large hydro development in modern times and the increasing appeal of off-stream and mine-repurposed pumped hydro. From micro-hydro in remote villages to pumped storage in decommissioned mine pits, he paints a picture of a diverse and sustainable future for hydroelectric energy. The episode closes with a powerful reflection on climate change, catchment management, and the crucial role of young engineers in this energy transition.
