The high penetration of weather-dependent renewable energy sources (WD-RESs) such as wind and solar has raised concerns about the security of electric power systems during abnormal weather conditions. The role of RESs has been discussed in worldwide blackout events, yet remains controversial. In this study, we find that although WD-RESs are non-dispatchable and weather sensitive, blackout intensities and extreme weather vulnerability are mitigated in high-penetration WD-RES grids. The causal effects of WD-RESs on blackouts generally decrease in high-penetration WD-RES power systems, and WD-RESs are not mainly responsible for the occurrence of blackouts in extreme weather conditions. The results of our research contribute to the debate on RES integration and power system security, offer a guide for the study of power system resilience and provide a reference for the ambitious high-penetration RES goals of the future. Renewable energy sources (RESs) are weather sensitive, raising questions about the vulnerability of high-penetration weather-dependent RES grids during extreme weather events. Here the authors find that blackout intensities and extreme weather vulnerability are mitigated in high-penetration weather-dependent RES grids.

Animals such as raccoon dogs, mink and muskrats are farmed for fur and are sometimes used as food or medicinal products1,2, yet they are also potential reservoirs of emerging pathogens3. Here we performed single-sample metatranscriptomic sequencing of internal tissues from 461 individual fur animals that were found dead due to disease. We characterized 125 virus species, including 36 that were novel and 39 at potentially high risk of cross-species transmission, including zoonotic spillover. Notably, we identified seven species of coronaviruses, expanding their known host range, and documented the cross-species transmission of a novel canine respiratory coronavirus to raccoon dogs and of bat HKU5-like coronaviruses to mink, present at a high abundance in lung tissues. Three subtypes of influenza A virus—H1N2, H5N6 and H6N2—were detected in the lungs of guinea pig, mink and muskrat, respectively. Multiple known zoonotic viruses, such as Japanese encephalitis virus and mammalian orthoreovirus4,5, were detected in guinea pigs. Raccoon dogs and mink carried the highest number of potentially high-risk viruses, while viruses from the Coronaviridae, Paramyxoviridae and Sedoreoviridae families commonly infected multiple hosts. These data also reveal potential virus transmission between farmed animals and wild animals, and from humans to farmed animals, indicating that fur farming represents an important transmission hub for viral zoonoses. Fur farming represents an important hub of cross-species transmission for viral zoonoses.
