/1 Latest @UniLUT research shows that #100RE in global power sector in 2030s is the least cost case: sciencedirect.com/science/articl…. Comparison to #WEO scenarios of #IEA and @SvenTeske /DLR scenarios. Modelling in 1-h temporal and 9 global regions resolution. 
/2 The @UniLUT scenarios reveal that #100RE anytime in 2030s is a least cost solution. Solar PV-battery is the inner core of least cost supported by wind power and other renewables. Sector coupling was not investigated but would further reduce system cost.
/3 Comparison to @SvenTeske /DLR reveals an interesting societal choice: low-cost with PV-wind-battery in the core vs higher resource/technology diversity for higher cost (+10-20%). Finally, different paths lead to #100RE and societies have the choice what feature to rate higher.
/4 Lack of transparency blocked NZE2050 inclusion. WEO-SDS & WEO-STEPS show worst case features: high system cost for low CO2 reduction. High cost options (fossil CCS, nuclear) are pushed and low cost options as PV are downplayed. Much better policy recommendations required.
/5 Key conclusion: “Thanks to low-cost electricity from solar PV and wind power, which can be complemented by other RE sources, the electricity sector can run on #100RE and energy storage 24/7, all year round, without relying on FFs (w or w/o CCS) & nuclear power.” ... in2030s.
