On December 10, the research team led by Professor Liu Kai from the School of National Safety and Emergency Management published a research paper titled Rising worldwide challenges to climate-induced extreme low-production events of photovoltaic and wind power in Nature Communications. The study systematically evaluates the evolution of risks associated with "Extreme Low-Production Events" in global PV and wind power under various future climate change scenarios. It provides a crucial scientific basis for promoting the construction of more resilient and secure new energy power systems.

Abstract:

The global shift toward solar photovoltaic (PV) and wind power is crucial to climate mitigation, yet climate change may intensify extreme low-production (ELP) events and affect power reliability. Here, we assess future ELP changes under low (SSP1-2.6), intermediate (SSP2-4.5), and high (SSP3-7.0) greenhouse gas and air pollutant emissions scenarios. Even under SSP1-2.6, rising ELP risks are projected to affect more than one-third of global regions, expanding to nearly two-thirds under SSP3-7.0, regardless of whether systems rely on PV, wind, or both. Increases in ELP for wind power are nearly inevitable, with over 75% of currently installed areas experiencing 14.0–24.5% greater production anomalies by the late century. PV power diverges strongly across scenarios, shifting from a 14.8% decrease in anomaly under SSP1-2.6 to a 26.4% increase under SSP3-7.0, particularly in East Asia. Additionally, climate-induced risks disproportionately narrow the benefits of PV development in low- and lower-middle-income economies, where ELP risks rise at 1.8 times the global rate under SSP3-7.0. Our results underscore the need for coordinated mitigation and adaptation to secure power reliability in a changing climate.
