Few studies explored the interaction effect between policy instruments and the policy environment on environmental governance. Based on policy instrument theory, this paper conducts fuzzy set qualitative comparative analysis (fsQCA) to explore the combined effect of policy instruments and the policy environment on the environmental governance efficiency of local governance. This study found four effective configurations of local government environmental governance, which can be summarized as the mandatory mode and the cooperative mode, and three inefficient configurations that can be summarized as the out-of-control mode. The results show that the regions adopting the mandatory mode are economically underdeveloped, while the regions using the cooperative mode are developed. Besides, local government competition leads to the softening of policy instruments, while government-enterprise collusion exacerbates the failure of environmental policy instruments. This paper summarizes the effective modes and reveals the reasons for the low efficiency of local government environmental governance in China. The conclusions provide not only empirical evidence for the study of policy instrument theory but also beneficial insights for the selection of environmental policy instruments and environmental governance practice.

Solar energy is the powerhouse where all potential and classified renewable energies lug their sources. The energy transformation from the Sun to electricity requires an adequate control scheme to maximise the generated power and enhance the system efficiency. Besides, more than half of solar irradiation on conventional Photovoltaic (PV) panels is lost. The PV thermal (PV/T) modules have been introduced to convert the lost irradiation to heat. Thus, a systematic review of system components, development, and strategies for grid-connected solar PVs plants is presented. Two solar PVs, traditional PV and PV/T, are evaluated. Each grid-tied PV component is considered a subsystem to analyse the potential improvement of grid-connected PVs. This is from solar resources to grid-tied PV inverter techniques. An intensive assessment of the system improvements is presented to evaluate PV plants’ benefits, challenges, and potential solutions. The improvement trends for the novel generation of grid-connected PV systems consist of applying innovative approaches. It is also found that intelligent strategies optimally ensure the overall efficiency of grid-tied PVs using real-time control and measurement under innovative applications and technologies. These methods effectively assist in enhancing grid-tied diverse solar power approaches. Therefore, this paper would offer a significant foundation for advanced research into the subject of grid-tied PV and PV/T and their innovation and/or technology development.

Energy is very vital for the economic development and prosperity of any nation. Expanding a country's use of renewable energy sources can help it meet its current and future energy needs, as well as spur economic growth. Sustainable energy supply, electrification rate, population shifts, and per-capita power use affect economic development and prosperity. Electricity use is a key sign of a country's economic growth, and as the economy grows, so does the need for energy. Electricity generation relies on the availability of primary sources, implementation of technology as well as on policy imperatives. The South Asian Association for Regional Cooperation is the regional intergovernmental organization and geopolitical union of states in South Asia. Its member states are India, Afghanistan, Bhutan, Bangladesh, Nepal, Maldives, Sri Lanka, and Pakistan. SAARC countries are wealthy in natural resources, yet economic growth is a difficulty. This study aims to assess the solar energy potential of SAARC countries, which has received little attention. Prior research on solar energy possibilities in SAARC concentrated on one country or group. According to the study, SAARC countries rely heavily on imported fossil fuels and a single energy source. Renewable energy sources, especially solar energy, are important for their sustainable expansion, diversity of energy basket, energy security, and fulfilling rising electricity demand. The SAARC region has superior daily average horizontal sun irradiances than the UK and Germany, indicating untapped potential for solar photovoltaic systems. This study aims to encourage stakeholders to execute efficient solar energy governance planning for sustainable growth.

The incremental capital-output ratio indicates the extent of capital efficiency as firms gradually become technically efficient. Therefore, we aim to empirically assess the linkage between energy intensity and incremental capital-output ratio from a holistic point of view, the first of its kind, by analyzing data from select South Asian countries, lower- and middle-income, and high-income countries. We use standard and robust cross-sectional augmented econometric methodologies for the empirical analysis using data from 1990 to 2018. We reveal unidirectional causation from the incremental capital-output ratio to energy intensity in five South Asian countries and 52 high-income countries. However, bidirectional causality is found between the incremental capital-output ratio and energy intensity for the 34 lower- and middle-income countries. The elasticity of the incremental capital-output ratio to energy intensity for South Asian countries is 0.15 in the long-run. By contrast, the same elasticities for lower- and middle-income and high-income countries are 0.11 and 0.003, respectively. The effect of the incremental capital-output ratio on energy intensity is significantly lower in high-income countries than in the other two groups due to technical inefficiency. Our results are expected to guide the policymakers in developing and emerging economies in adopting optimal policies to achieve efficient and sustainable production and consumption.

Increased urban air temperature considerably affects the health, comfort and consequently the quality of life in urban spaces. Urban design and planning studies, therefore, face an increasing challenge as they aim to improve Outdoor Thermal Comfort (OTC) and microclimate conditions of urban environments. Analysing OTC is more challenging when compared to indoor thermal comfort since a wider range of interrelated parameters exists in outdoor environments. Therefore, this research aims to classify urban studies that investigate OTC by conducting a comprehensive review based on key metrics such as approaches taken, methodologies and spatial and temporal scales. By extracting the key findings, this research forms an integrated framework of these metrics that presents a thorough view of the OTC concept in the context of climate-sensitive studies. Furthermore, this research elaborates on the main two groups of parameters affecting OTC including environmental and human-based parameters. Exploring the intricate inter-relationships of these two groups of parameters clarifies their contribution to OTC. Results of this study help architects and urban planners to improve their climate-sensitive strategies and support the decision-making process by providing a comprehensive perspective about different aspects of OTC. Finally, recommendations for future research are outlined.

Nuclear energy has sparked international attention as one of the most important strategies for reducing emissions thanks to its ability to provide low-carbon power. Based on this interesting fact, the current research explores the effect of nuclear energy on CO2 emissions in the leading countries by nuclear power consumption using a quarterly dataset from 1990 to 2019. The study employs the quantile-on-quantile (QQ) estimator, which accounts for both non-parametric and conventional analyses and enhances the provision of unbiased and consistent estimates. In addition, the Granger causality in quantiles approach is adopted to assess the causality in quantiles between the variables of investigation. The outcomes from the QQ estimator reveals that in the majority of the quantiles, nuclear energy contributes to decreased degradation of the environment in the USA, France, Russia, South Korea, Canada, Ukraine, Germany, and Sweden. Contrawise, the feedbacks from Spain and China expose that Nuclear Energy Consumption (NUC) contributes to the deterioration of the environment. Moreover, the outcomes of the causality test disclose that nuclear energy and CO2 emissions can predict each other in the majority of the quantiles. The findings above provide profound ramifications for policymakers planning nuclear energy and CO2-emission policies towards achieving sustainable environment in the sample countries and beyond..

As a new approach, biodegradable solid polymer blend polymer electrolytes are prepared using a synthetic polymer Poly [vinyl pyrrolidone] (PVP) and a biopolymer Starch with constant amount of Ammonium ceric nitrate. The Biopolymer starch is used to enhance the biodegradability of the polymer membranes. The polymer electrolytes are prepared by solution casting method using deionized water as solvent. The prepared electrolytes are analyzed with structural, vibrational, electrical and electrochemical behavior by using different characterization techniques. The amorphous nature of the blend polymer electrolytes has been confirmed by X-Ray diffraction (XRD) analysis. PVP/cassava starch/ammonium ceric nitrate polymer electrolyte shows high amorphous nature. In FTIR study, polymers-salt complexation and molecular vibrations are observed in the electrolytes. The ionic conductivity and dielectric measurement of the electrolytes are carried out by impedance spectroscopy. The maximum ionic conductivity of 8.1 × 10−6 S/cm is observed at room temperature for 80% PVP: 20% cassava starch: 2% ammonium ceric nitrate (ACN) system. The dielectric properties of the prepared polymer electrolytes are also analyzed. The electrolyte having higher ionic conductivity is tested with cyclic voltammetry (CV) and linear sweep voltammetry (LSV) studies that reveal the electrochemical properties and range of potential window of the polymer electrolyte.

There has been an increasing effort to promote renewable energies as climate change mitigation measures in Japan. Yet, the installation of wind turbines and solar photovoltaic (PV) power plants is being contested in several parts of the country. There is a need to understand these oppositions to reduce the number of delayed projects or overcome future barriers. Thus, in this study, we investigated cases of opposition movements and legal proceedings against wind and solar PV power development. Results indicated that landscape elements and socio-ecological factors motivate local oppositions. For instance, there were cases filed due to landscape view obstruction caused by wind turbines and solar panels. In terms of socio-ecological barriers, examples of cases scrutinized showed opposition caused by the potential impact on recreational activities such as climbing and hiking trails. Additionally, we observed that there were differences in the scope and scale of opposition movements and legal proceedings between wind and solar PV power projects. These differences were related to the scale (project size) and duration (construction to operation) of the project coupled with the renewable energy-related legal system changes in Japan. We observed that the overall legislative framework is frequently designed at the national level while challenges in project site selection are dealt with at the municipal- and prefectural-level. The findings of this study can help policymakers to revise and/or develop legal systems that minimize impacts on landscape and social elements while satisfying the demand for renewable energy transitions.

By developing the mathematical model of a serial multi-stage reverse electrodialysis reactor (REDR) system for wastewater treatment, this paper numerically simulates the degradation process of azo dye (methyl orange) dyeing wastewater. The operation performances of the serial system with an anode and cathode synergetic degradative circulation mode are explored by numerical simulation. The influences of operation parameter variations on key performance indicators are investigated and discussed. Results indicate that the serial system can achieve excellent electricity conversion efficiency and degradative performance under an appropriate output current condition. A high initial MO concentration and electrode rinse solution (ERS) flowrate are helpful to improve the treatment performance of the system. A low concentrated solution (CS) concentration is beneficial for raising the electricity conversion efficiency and reducing the total energy consumption (TEC).

In this paper, a genetic algorithm is applied to optimize the sizing of an autonomous renewable energy multi-source system for reliable and economical supply of energy. The multi-source system is composed of a photovoltaic generator, a pumped storage hydropower system and a battery. The system will power public lighting and operate a garden fountain in the Botanical Garden, located in the Alexandre Aibéo Park in Covilhã (Portugal). Solar irradiance is initially simulated for a reference photovoltaic capacity (25 kWp) over one year by the PVsyst software for the city of Covilhã. Two objective functions are used for sizing optimization: the loss of power supply probability (LPSP) and the levelized cost of energy (LCE). The LCE takes into account the capital cost, the replacement cost and the cost of operation and maintenance. The genetic algorithm is used to determine the best configuration of the different subsystems (photovoltaic generator capacity, upper water reservoir capacity and battery capacity). The originality of this work lies in the combination of two storage elements with different dynamics, the introduction of an adapted energy management strategy (EMS) allowing to manage energy flows between the different subsystems and to control the process of charging/ discharging storage elements, and multi-objective optimization (considering technical and economic criteria) of the sizing of the autonomous photovoltaic/pumped storage hydropower/ battery hybrid system using genetic algorithm.
