Can You Run a Grid on 100% Wind + Solar? South Australia Shows Us How

Welcome to South Australia, a place where the winds of change are quite literal and the sun doesn’t just warm our homes but also powers them. I recorded this video in beautiful Adelaide when I visited recently, because South Australia is leading the world in several key aspects of the energy transition. South Australia has gone from a coal powered electricity grid with virtually no renewables in 2008 to 70% renewables with zero coal power plants today, a mere 15 years later. And, they’ve done it the hard way, with none of the “easy“ clean energy sources (hydro, geothermal, nuclear). They’ve done it with variable renewables wind and solar. If you look at any of the large net zero scenarios you will see that the bulk of the future world’s electricity generation is expected to come from wind and solar. It is simply not possible to expand hydro everywhere so that each country can follow Iceland or Norway’s lead. Geothermal, biomass and nuclear each have their own issues with location, scalabi
