88% of New Zealand’s electricity is renewable, but that’s only part of the picture. The reality is that our total energy system — including heat and transport — is only around 30% renewable. So how do we bridge that gap? Isabelle takes us through a range of groundbreaking projects aimed at decarbonizing our entire energy system. In this episode, we’re joined by Isabelle Chambefort, Energy Futures Science Lead at GNS Science, to explore groundbreaking projects tackling every angle of the energy crisis. From carbon-negative concrete to supercritical geothermal, geological energy storage and better home appliances, Isabelle explains the bold innovations shaping a cleaner, more resilient energy future. Discover how New Zealand science can drive change in hard-to-decarbonize sectors like agriculture, construction, and transport, and why energy efficiency and alternative storage solutions are key to unlocking a truly renewable energy system.
