Renewable electricity by the numbers gets thumbs-up in new study

(Tech Xplore)—Conclusions that we can reach a stage where renewable electricity runs the world may not sit easily with skeptics but a study contends that it is feasible by 2050.

Climate News Network said the researchers believe 100% renewable electricity is attainable by mid-century, or even earlier.

The study is titled “Global Energy System based on 100% Renewable Energy – Power Sector” The study was carried out by Finland’s Lappeenranta University of Technology (LUT) and the Energy Watch Group (EWG).
The Energy Watch Group (EWG) is described as “an independent, non-profit global network of scientists and parliamentarians.”

The study was presented earlier this month during a renewable energy showcase event on the sidelines of the United Nations Climate Change Conference COP23 in Bonn.

The authors spelled out the extent to which they say this is feasible: A global electricity system fully based on renewable energy is feasible at every hour throughout the year. It is said to be more cost effective than the existing system, largely based on fossil fuels and nuclear energy.

“There is no reason to invest one more dollar in fossil or nuclear power production,” said EWG president Hans-Josef Fell.”
The study pointed out benefits accompanying such a transition to renewables—bringing greenhouse gas emissions in the electricity sector down to zero and reducing total losses in power generation. It would create 36 million jobs by 2050, 17 million more than the sector has today.

Total levelized cost of electricity (LCOE) on a global average for 100% renewable electricity in 2050 is given as €52/MWh (including curtailment, storage and some grid costs), compared to €70/MWh in 2015.

Their model, said Alex Kirby in Climate News Network, “simulates the most efficient energy supply with an optimal mix of technologies and locally available renewable resources.”
