Can we run the world on renewables alone? Various researchers have tried to model how a given country might run a grid using mostly renewables, oftentimes finding that carbon-negative technologies, advanced nuclear power, and even coal power plants equipped with CCS will be a part of the solution set. But no one has produced a comprehensive model that shows how we can run the world on renewables alone, while accurately modeling the weather and grid conditions at a very discrete scale, at hourly resolution, using data on the renewable resources in each region, and determining how that would work while selecting the least-cost resources… until now. In this episode we speak with a researcher from Lappeenranta University of Technology in Finland, one of an international team of 14 scientists who have spent the past four and a half years performing research, data analysis, and technical and financial modeling to prove that a global transition to 100% renewable energy is economically competitive with the current fossil and nuclear-based system, and could reduce greenhouse gas emissions in the energy system to zero even before 2050. This first-of-its-kind study outlines how the world could limit warming to 1.5°C with a cost-effective, global, 100% renewable energy system that does not use negative carbon technologies, and provides all the energy needed for electricity, heat, transport and desalination by 2050.
