Summary: Solar photovoltaics have the potential to replace fossil fuels and contribute to lower-cost zero-emission energy systems. The initial benefits of providing solar power to the electricity system are significant, especially in deep decarbonization scenarios. However, the value of additional solar power decreases as cumulative solar capacities increase. Taking full advantage of low-cost solar energy requires the development and deployment of low-cost approaches to energy supply or electricity load shifting.

Summary: 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.

Summary: This study investigates the impacts of climate change on offshore wind resources in Northern Europe over the 21st century, using the most up-to-date narratives of societal development and land use, the Shared Socioeconomic Pathways (SSPs). Three scenarios are considered: high-emissions (pessimistic) scenario SSP5-8.5, intermediate scenario SSP2-4.5, and low-emissions (optimistic) scenario SSP1-1.9. The results indicate an overall decline in wind power density, particularly in the high-emissions scenario and certain regions, while slight increases are projected in some areas of the Baltic Sea. Reducing emissions as advocated by current climate objectives not only weakens the declining trend but also leads to a more stable resource.

Summary: This study analyzes the opportunities and challenges faced when using machine learning methods to improve circularity in management of solid waste in Latin America and the Caribbean (LA&C). The authors conducted a systematic literature review and bibliometric analysis and found that the challenges in improving solid waste management in LA&C include lack of reliable data, low waste utilization rate, need for changing consumption patterns, social inclusion of informal waste collectors, and limited knowledge of decision makers about the potential of machine learning methods. Hybrid models, improved Internet-of-Things (IoT) applications, and integration of Geographic Information System (GIS) data with machine learning methods are identified as potential ways to accelerate the transition to circular economy in LA&C.
