The study by Lappeenranta University of Technology (LUT) and the Energy Watch Group (EWG) shows that a 100% renewable electricity system would bring greenhouse gas emissions in the electricity sector down to zero, drastically reducing total losses in energy generation and create 36 million jobs by 2050.
The study was presented on November 8, 2017 during the Global Renewable Energy Solutions Showcase (GRESS) event on the sidelines of the United Nations COP23 Conference on Climate Change in Bonn.
The results of the study are revealing, EWG says in a statement: “A global electricity system fully based on renewable energy is feasible at every hour throughout the year and is more cost-effective than the existing system, which is largely based on fossil fuels and nuclear energy “.

Thus, they assure existing renewable energy potential and technologies, including storage, can generate sufficient and secure power to meet all the world’s electricity demand by 2050. Moreover, they state that with a 100% renewable electricity system, the total levelised cost of electricity (LCOE) on a global average in 2050 would be €52/MWh (including curtailment, storage and some grid costs), compared to €70/MWh on average in 2015.
” A full decarbonization of the electricity system by 2050 is possible for lower system cost than today based on available technology. Energy transition is no longer a question of technical feasibility or economic viability, but of political will”, Christian Breyer, lead author of the study, LUT Professor of Solar Economy and Chairman of the EWG Scientific Board said.
A transition to a 100% renewables electricity system would bring greenhouse gas emissions in the electricity sector down to zero and drastically reduce total losses in power generation. It would create 36 million jobs by 2050, 17 million more than today, this independent association of scientists and parliamentarians in Germany claims in the statement.
”There is no reason to invest one more Dollar in fossil or nuclear power production”, EWG President Hans-Josef Fell said. “Renewable energy provides cost-effective power supply. All plans for a further expansion of coal, nuclear, gas and oil have to be ceased. More investments need to be channeled in renewable energies and the necessary infrastructure for storage and grids. Everything else will lead to unnecessary costs and increasing global warming.”
[pullquote] “Wind energy would increase to 32% of total electricity by 2030. In 2050 it would only account for 18% while solar photovoltaic would increase from 37% in 2030 to approximately 69% in 2050” [/ pullquote]
The study predicts that while wind energy would increase to 32% of total electricity by 2030, in 2050 it would only account for 18% while solar photovoltaic would increase from 37% in 2030 to approximately 69% in 2050, year in which hydroelectricity would represent 8% and bioenergy 2%.
As is already known, batteries are the key backup technology for photovoltaic solar energy. Indeed, the report says that in 2050 31% of total demand will be covered with storage, and of this percentage, 95% will be covered only by batteries. “Battery storage will provide mainly diurnal storage, and renewable energy based gas will provides seasonal storage”, they explain.
In addition, they specify that greenhouse gas emissions will significantly decrease from approximately 11 GtCO 2 eq in 2015 to zero emissions in 2050 or before.
As for total losses, they would represent around 26% of total electricity demand, compared to the current system in which approximately 58% of the primary energy contribution is lost, the statement continues.
