The TranSim modelling work shows that the negative effects associated with the transition—recession, stagnation, stagflation, increasing inequality and asset stranding—are positively related to the capital intensity of green energy production and reductions in EROI. Policy makers should pay close attention to the overall EROI of the entire energy system when determining energy policy. If significant reductions in EROI are unavoidable, then policy could be used to mitigate some of its negative economic effects.
