7/ Reliance on fossil fuels (gas, oil) still creates unprecedented vulnerability for power systems. The more energy requirements needed in the natural gas and oil upstream production; the more dramatic decline is observed in #EROI trends.

6/ The sustainability risk of the systemwide #EROI is reanalysed through the provision of annual energy investment flows (AEF). The integration of large-scale capacities leads to greater fluctuations in AEF trends. The AEF trends of #100RE scenarios do not fall below 6 even in extreme cases.

5/ #EROI trends of #100RE are heavily influenced by storage expansion and the ratio of PV and wind. Diversification of RE technologies ensures more consistent #EROI trends, with the exception of large geothermal power plants due to energy-intensive processes.

4/ Accelerating the energy transition temporarily causes a significant decline in #EROI due to the introduction of new capacities. However, as the system moves closer to #100RE the #EROI trends begin to stabilise.

3/ Key findings signify that 9 energy transition scenarios remain at the upper limit of the net energy cliff (above 10), and they are feasible from a techno-economic perspective. #100RE systems do not result in any significant disruption to #EROI trends.

2/ Methods: The energy quality discrepancy of #EROI analyses was overcome with alignment to the energy quality level of electricity (bsky.app/profile/chri...) and analysing #EROI on system level instead of technology level.

1/ New research @UniLUT @hasretshn.bsky.social doi.org/10.1038/s414... examines the net energy performance of 9 #decarbonisation global energy transition scenarios until 2050 by applying the systemwide #EROI at the electricity level.
