Summary: Solving the problem of photovoltaics abandonment and power limitation and improving resource utilization is crucial for the sustainable development of the PV industry. This research focuses on the synergistic management of PV power generation and proposes a complex value chain system called photovoltaics energy storage system (PVESS) with PV power generation subsystem and energy storage subsystem. A value co-creation analysis framework for capacity allocation of PVESS under the Energy Internet is analyzed, and a hybrid energy storage system (HESS) combining battery energy storage system (BESS) and superconducting magnetic energy storage system (SMES) is proposed. A multi-objective collaborative decision model is established for HESS, and optimal system configuration is determined using the hybrid particle swarm algorithm (HPSO) and Vlsekriterijumska Optimizacija I Kompromisno Resenje (VIKOR) method. The validity and feasibility of the model are proved through collaborative decision making and sensitivity analysis.

Summary: This study analyzed the energy consumption of two masjids in Saudi Arabia and found opportunities for energy rationalization. A photovoltaic system was used to achieve nearly zero bill or nearly zero energy building conditions. The energy use intensities of the masjids were 111 kWh/m2 and 121 kWh/m2, respectively. Cooling accounted for the highest energy consumption, followed by lighting. Improving the building envelope saved about 60% of AC energy load, while increasing ambient temperature resulted in a 30% increase in electricity requirement for ACs. Changing the set-point temperature allowed for a 27% electrical energy savings on a summer day. The environmental benefits of using solar energy were also identified.

Summary: Given the challenges in grid expansion, access to reliable electricity, and climate and development priorities in low-income countries, microgrids and off-grid solar projects present a viable solution for rural electrification. This study proposes a spatial framework for off-grid solar energy planning, using Geographic Information System and decision-making methods, to identify optimal locations for solar microgrid projects in Mozambique. The results show that certain criteria, such as climatology, orography, and social factors, significantly influence the selection of suitable sites. Considering geographical constraints, around 49% of the study area is suitable for off-grid solar microgrids, while 51% falls into not feasible and restricted areas due to conservation and high-risk factors.

Summary: This paper examines the impact of social capital (SC) on subjective quality of life to address the limitations of current observable indicators in informing public policy. The study analyzes a large-scale survey of 100,956 respondents from 37 countries, encompassing both developed and less developed nations. The empirical findings reveal that SC has a stronger association with improved subjective health and higher satisfaction in low-income countries compared to high-income countries. Additionally, low-income countries perceive lower levels of economic inequality at the community level when SC is higher, while high-income countries exhibit higher levels. The study also highlights the positive impact of higher levels of educational attainment on the perception of economic inequality, which decreases with SC. Enhancing SC may contribute to enhancing quality of life in most low-income countries, with lifestyle and cultural factors also playing a significant role. These findings emphasize the importance of non-economic factors in promoting better lives, necessitating further research into the social aspects of life.

Summary: Acquiring and absorbing knowledge at different geographic levels is crucial for firms' technological learning and innovation processes. This study discovers localized learning in citation networks within the solar photovoltaic balance-of-systems (PV BOS) sector, with the extent of localized learning varying based on the relevance of technologies to local contexts. Therefore, this research suggests that the impact of local and non-local knowledge on patent quality depends on technological characteristics. By examining the different levels of local dependence on four types of technologies in the PV BOS industry, it is found that local knowledge has a greater influence on innovation quality for technologies more rooted in local contexts, while non-local knowledge has a greater influence for technologies less relevant to local contexts.

Summary: Household solid fuel use is detrimental to health and the environment. The Indian government's PMUY subsidy has successfully promoted the adoption of LPG by millions of households. However, there is limited understanding of the decision-making process to reduce solid fuel use after transitioning to cleaner fuels. This study found that factors such as household wealth, social status, education level, and the prevalence of LPG use in the village are positively associated with LPG consumption and the discontinuation of solid fuel use. On the other hand, factors such as distance to LPG refill delivery, household size, and the PMUY subsidy are negatively associated with the share of LPG use.
