Summary: We evaluate the absorptive capacity of renewable energy deployment in Africa and find significant regional heterogeneities between West Africa and East Africa. West Africa has a stronger capacity to embrace the adaptation of renewable energy, and renewable energy deployment exhibits path dependency in both regions. Our findings suggest significant potentials for both regions to benefit from renewable energy deployment, but without financial backing from policymakers, implementation is likely to be delayed, exposing these regions to long-term economic and environmental vulnerabilities.

Summary: Countries that are more vulnerable to climate change and have less carbon-intensive economies tend to deploy higher shares of renewable energy. However, the influence of carbon tax on renewable energy deployment is statistically insignificant. Supporting renewable energy development requires relevant policies and incentives in place to reduce reliance on fossil fuels.

Summary: This paper examines the impact of energy security and economic complexity on renewable energy in G7 countries from 1980 to 2017. The results show that energy insecurity is a driving force for renewable energy development, while economic complexity hampers it. Income has a positive effect on renewable energy, and the role of trade openness varies. These findings have valuable policy implications for G7 countries.

Summary: Utilizing renewable energy in wastewater treatment plants is a practical way to achieve energy self-sufficiency and reduce carbon emissions. This study focuses on the optimization of hybrid renewable energy in multiple plants, providing global optimal solutions and cost-effective resource management. The approach was applied to a city-scale wastewater treatment system in Guangzhou, China, showing that renewable energy can achieve energy self-sufficiency and reduce overall costs and greenhouse gas emissions.

Summary: A conflict over the reduction in development finance for fossil-fuel projects emerged between Western and African governments at both last year's COP26 and the recent COP27. This indicates the importance of understanding the role of politics and power in energy transitions in lower income African countries. This paper argues that while countries share concerns over energy security and domestic energy development, differences in resource endowments significantly influence the potential for energy transitions.

Summary: The study reveals that both non-renewable and renewable energy consumption have a significantly positive impact on economic growth, but this relationship varies across different income and regional classifications. Furthermore, capital and labor also play a significant role in driving economic growth. Therefore, promoting the renewable energy sector for efficient and environmentally friendly energy use is crucial.

Summary: This paper examines the relationship between renewable energy and energy efficiency in China using data envelopment analysis and panel threshold regression models. The results show that renewable energy generally improves energy efficiency, but there are heterogeneity and nonlinear characteristics in provinces with net electricity exporting and importing. Lower levels of renewable energy significantly improve energy efficiency and are more likely to achieve sustainable development goals. It is recommended to allocate more renewable energy quotas to economically developed and high energy-consuming provinces and provide comprehensive energy efficiency guarantees for optimal emission mitigation.

Summary: The study found that political barriers are the most significant obstacles to deploying mini-grids, accounting for 44.3%, while access to finance is considered to account for 11.7% of the importance share. Ghana's universal electrification still needs to overcome economic, technical, social, and environmental barriers.

Summary: As renewable energy production increases, the demand for energy storage and carrier systems becomes crucial. Hydrogen, with its low volumetric energy density and challenging storage conditions, is positioned as a powerful tool for this purpose. Liquid organic hydrogen carriers (LOHCs) are considered a promising option for hydrogen storage, but the reactor technology for LOHC processes has not been thoroughly assessed. In this study, a three-phase reactor analysis is conducted to evaluate the two most important reactors for three-phase reactions, trickle bed and slurry. The influence of operating and design variables is studied for two attractive LOHC systems. The results show that the resistance in hydrogenation slurry reactors is mainly gas-liquid in the first region and eventually transitions to kinetics control in the second region. Trickle bed reactors, on the other hand, are primarily controlled by mass transfer. Surrogate models are developed to optimize reactor performance and facilitate the deployment of LOHC systems.

Summary: The use of non-renewable energy sources increases environmental impacts. This article analyzes the trends in renewable electricity supply in the G20 countries and finds that Brazil and Canada have the largest renewable electricity matrices, while Saudi Arabia has the smallest. The countries with the highest GDP are not necessarily the largest producers of renewable electricity, and hydroelectric energy is still the dominant source. However, wind and solar energy are growing in their contribution to the electrical matrices, and other sources are showing a slow but steady increase in participation.
