A new report by LUT University in Finland and the Energy Watch Group (EWG) in Germany outlines a cross-sector, global 100% renewable energy system, backing up the version it released last year. The full modelling study simulates a total global energy transition in the electricity, heat, transport and desalination sectors by 2050. It claims that a transition to 100% renewable energy would lead to a system that was economically competitive with the current fossil and nuclear-based system. It could also, the study says, reduce greenhouse gas emissions in the energy system to zero by 2050, or perhaps earlier, without relying on negative CO2 emission technologies.

LUT/EWG have also developed a range of national roadmaps for the transition to 100% renewable power. The new global 100% renewable study builds on that work, and earlier global studies, covering all sectors.

“The study’s results show that all countries can and should accelerate the current Paris Climate Agreement targets,” said Christian Breyer, professor for solar economy at LUT. “A transition to 100% clean, renewable energies is highly realistic – even today, with the technologies currently available.”

Hans-Josef Fell, former member of the German Parliament and president of the Energy Watch Group, added: “The report confirms that a transition to 100% renewables is possible across all sectors, and is no longer more expensive than the current energy system. It shows that the whole world can make the transition to a zero emission energy system. That is why all political powers around the world can and should do much more to protect our climate than they currently envision.”
