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.
Dmitrii Bogdanov is a researcher and doctoral student at the Solar Economy Laboratory at LUT – the Lappeenranta University of Technology in Finland. For the past 5 years he has worked on renewable energy systems and energy transition. His focus is on optimal transition pathways and the role of the emerging technologies (PtX, battery storage, HVDC, electric vehicles) and new concepts (prosumers, vehicle-to-grid) in energy transition. At the Solar Economy Laboratory, he is responsible for study methodology and model development, regional studies, and global studies along with his colleagues and their professor, Christian Breyer.
