As costs for renewable electricity keep falling and emerging markets lead in green energy investments, a global power system fully based on renewable energy is no longer a long-term vision, but a real option.
The Lappeenranta University of Technology and the Energy Watch Group are working on a new unprecedented study, which models the global energy system fully based on 100% renewables across four energy sectors of electricity, heat, mobility and industrial demand.
The research explores new scientific territory, as it is the first study that models the global 100% renewable energy system on an hourly basis. But it also has major political implications: It shows that energy transition is no longer a question of technical feasibility or economics – it is purely a question of political will.
The preliminary results show: 100% renewable electricity worldwide is not only feasible at every hour throughout the year, but also economically more cost-effective than the fossil or nuclear energy systems. The results will be presented for the first time at COP23, on the occasion of the Global Renewable Energy Solutions Showcase event (GRESS) in Bonn on November 7-8, 2017.
The project is co-funded by the German Federal Environmental Foundation (DBU) and Stiftung Mercator.
