This study explores the impact of climate change on global solar energy potential, finding a decrease in photovoltaic potential in the Indian subcontinent and China in the autumn due to increased post-monsoon cloud cover. There is a consistent decrease in North America and Australia, while in Europe, the decrease in photovoltaic potential is restricted to the winter season. However, there is a mild decrease in photovoltaic potential in Africa during the southern summer and a consistent decrease in concentrated solar power worldwide.
Sustainable Development Goals (SDGs) of the United Nations (UN) underline the importance of harnessing renewable energy sources for enhancing access to clean energy without compromising the global emission goals. This study explores the impact of climate change on global solar energy potential in the near-(2015-2040) and far-future (2041-210 0). Simulated energy variables from five General Circulation Models (GCMs) participating in the Coupled Model Intercomparison Project phase 6 (CMIP6) for three different Shared Socioeconomic Pathways (SSPs) -SSP1-2.6, SSP2-4.5 and SSP5-8.5 are used for the assessment. It is found that there is a 6-10% decrease (with respect to 1981-2014 climatology) in Photovoltaic (PV) potential in the Indian subcontinent and China in the boreal autumn that is possibly linked to increased post-monsoon cloud cover. A consistent decrease is noticed in North America and Australia, whereas in Europe, the projected decrease in PV potential, even for the worst emission scenario (SSP5-8.5), is restricted only to the boreal winter season, thereby posing no real threat to future PV power planning. However, a mild decrease in PV potential in Africa during austral summer and a consistent decrease in Concentrated Solar Power (CSP) all over the world contradict earlier studies.(c) 2022 Elsevier Ltd.
