Description
This study presents the energy system module of FRIDA, a feedback-rich integrated assessment model designed to represent the co-evolution of human and natural systems. The module is fully endogenous, linking energy demand, investment, supply, and climate impacts through dynamic feedbacks rather than optimization or exogenous allocation. It covers fossil, renewable, and nuclear technologies, capturing capital accumulation, learning effects, resource constraints, and climate-related infrastructure damage. We investigate the effects of the timing of ambitious carbon taxes and energy subsidies, nearly eliminating energy emissions and limiting warming, but also generating severe recessions and inflationary pressures.
