摘要

太阳能将成为最大的可再生能源,为实现全球碳中和做出贡献。除了众所周知的太阳能供应的时间间歇性之外,当地应对极端天气的能源需求也会进一步给能源网带来压力;供需双方都会受到未来气候变化的巨大影响。在此,我们通过考虑太阳能供需失衡来重新定义太阳能干旱事件。观测和多模型模拟显示,在过去三十年中,人为因素加剧了全球太阳干旱的频率。此外,与 SSP2-4.5 途径相比,碳中和途径 SSP1-2.6 可以在 2090 年代将太阳干旱频率和严重程度的增加分别减缓 60% 和 63%。我们的研究表明,太阳能的稳定性和安全性对实现碳中和具有共同效益,特别是在发展中国家,当地的供需失衡是一个主要问题。

Global Solar Droughts Due To Supply-Demand Imbalance Exacerbated by Anthropogenic Climate Change

Global Solar Droughts Due To Supply-Demand Imbalance Exacerbated by Anthropogenic Climate Change

Solar power will become the largest renewable energy source, contributing to global carbon neutrality. In addition to the well-recognized temporal intermittency of solar energy supply, the local energy demand to cope with extreme weathers can further stress the energy grid; both the supply and demand can be greatly influenced by future climate change. Here, we redefine solar drought events by considering supply demand imbalance in solar power. Observation and multi-model simulations reveal an anthropogenic exacerbation of global solar drought frequency in the past three decades. Moreover, compared to the pathway SSP2-4.5, the carbon neutrality pathway SSP1-2.6 can mitigate the increasing frequency and severity of solar droughts by 60% and 63% in the 2090s, respectively. Our study suggests a co-benefit of solar energy stability and security toward carbon neutrality, especially in developing nations where the local supply demand imbalance is a major issue.
