Fig. 5: Annual electricity system costs by scenario.
From: Increased energy use for adaptation significantly impacts mitigation pathways
a Total electricity system costs in trillion $, 2005 Purchasing Power Parity (PPP). b Additional electricity system costs in the mitigation scenarios with respect to the current policy, in trillion $(2005, PPP). c Variation in the cumulative electricity system costs associated to the more ambitious mitigation policy scenarios with respect to the current policy, in trillion $(2005, PPP). All projections are presented alternatively for the case with (solid lines) or without (dotted lines) adaptation. Operative fuel expenses for fossil-based power generation are included in the electricity system costs. Scenarios: Current policies (C.Pol), 2.5 °C and well-below 2 °C (W.b. 2 °C). Results presented in panel a and b for the scenario 2 °C are not shown to avoid clutter and can be fund in the Supplementary Material.
