“Energy transition is no longer a question of technical feasibility or economic viability, but of political will”, Christian Breyer

energywatchgroup.org/new-study-100-…
Existing renewable energy potential and technologies, including storage can generate sufficient and secure power to cover the entire global electricity demand by 2050.
Total levelised cost of electricity (LCOE) on a global average for 100% renewable electricity in 2050 is €52/MWh (including curtailment, storage and some grid costs), compared to €70/MWh in 2015.
Due to rapidly falling costs, solar PV and battery storage increasingly drive most of the electricity system, with solar PV reaching some 69%, wind energy 18%, hydropower 8% and bioenergy 2% of the total electricity mix in 2050 globally.
Wind energy increases to 32% by 2030. Beyond 2030 solar PV becomes more competitive. The solar PV supply share increases from 37% in 2030 to about 69% in 2050.
Batteries are the key supporting technology for solar PV. The storage output covers 31% of the total demand in 2050, 95% of which is covered by batteries alone. Battery storage provides mainly diurnal storage, and renewable energy based gas provides seasonal storage.
Global greenhouse gas emissions significantly reduce from about 11 GtCO2eq in 2015 to zero emissions by 2050 or earlier, as the total LCOE of the power system
The global energy transition to a 100% renewable electricity system creates 36 million jobs by 2050 in comparison to 19 million jobs in the 2015 electricity system.
The total losses in a 100% renewable electricity system are around 26% of the total electricity demand, compared to the current system in which about 58% of the primary energy input is lost.
