Summary: This study investigates the nonlinear relationship between household composition and residential electricity consumption using threshold models. It finds that the effects of household composition and household size on electricity use differ based on specific household size and level of electricity use. Policymakers should focus on improving residential electricity efficiency and developing strategies for small households.

Summary: The design, structure, and materials of a solar dish concentrator system have a significant impact on its performance and cost. This paper introduces an economic solar paraboloidal concentrator (ESPC) that features innovative design and achieves a stagnation temperature of around 400°C. A new optical performance parameter based on the stagnation temperature is proposed. Comparative tests with a commercial solar paraboloidal concentrator (CSPC) show that ESPC has a longer heating cycle period but costs 58% less than CSPC. Consequently, ESPC has a shorter payback period.

Summary: This study evaluates the lifecycle of hydrogen-driven power generation using total efficiency. Two case studies find a significant difference in total efficiency between hydrogen produced from fossil fuels and green hydrogen derived from excess renewable energy, with green hydrogen achieving higher total efficiency. The use of natural gas as the primary source for hydrogen has a critical impact on total efficiency, especially in cases where the gas needs to be transported from far away. The study highlights the importance of considering the impact of fuel preparation stages in thermodynamic analyses and evaluations.

Summary: This study examines the nonlinear impact of non-renewable and renewable electricity consumption on the economic development of Thailand. The results show that renewable electricity consumption has a negative influence on economic growth during the expansion regime, but a positive influence during recession regime 2. Non-renewable electricity consumption has a positive impact on growth only during the expansion regime. Importantly, the effects of non-renewable and renewable electricity consumption on economic development are asymmetric between the two regimes.

Summary: Improving energy efficiency is crucial for sustainable economic development and environmental protection. This study uses the TOPSIS method to monitor the energy efficiency of Turkey and analyzes the effects of several contextual variables. The results show that increasing renewable energy consumption and capital stock-labor force ratio enhance energy efficiency, while increasing carbon emissions-total energy consumption ratio decreases it. The nonlinear model also indicates asymmetric effects in the long run but not in the short run.

Summary: The purpose of this research is to analyze the impact of various factors such as innovation, economic growth, financial development, trade, foreign direct investment (FDI), electricity consumption, and urbanization on environmental degradation in Pakistan. The study uses the dynamic autoregressive distributed lag model (ARDL) and graphs to examine the changes in the independent variables and their effects on carbon emissions. The findings show that energy consumption, GDP growth, urbanization, and trade have negative short-term effects on carbon emissions. In the long term, only GDP growth, trade, and urbanization significantly impact emissions. Financial development and FDI contribute to reducing environmental degradation in both the short and long term, while innovation has a positive effect on carbon emissions. Policy recommendations are provided based on the findings.

Summary: This paper examines the impact of renewable energy use on the output elasticities of capital and labor, and subsequently, the factor shares in seven European Union countries from 1986 to 2015. The analysis reveals the presence of thresholds in renewable energy consumption, with significant consequences for factor shares. The study also finds changes in output elasticities for other threshold variables, such as oil and gas or coal production. These findings highlight the complex and non-linear relationship between energy sources and economic growth, emphasizing the importance of promoting renewable energy in national energy systems.

Summary: Despite the increasing research on the causes of environmental degradation, the uniqueness of nations emphasizing resource depletion has been largely overlooked. This study examines the impact of natural resource rent (NRR), GDP, and their interaction on environmental degradation in India, controlling for urbanization and energy use. Using data from 1970 to 2018 and applying dynamic autoregressive distributed lag (DARDL) simulation and frequency domain causality (FDC) approach, the study finds heterogeneous yet significant impacts of economic activities on environmental quality and validates the existence of an N-shaped Environmental Kuznets Curve (EKC) hypothesis with CO2 emission as the dependent variable.

Summary: This study explores the impact of innovations in sustainable energy technologies on decarbonization in the 20 most innovative nations globally. Using the Panel Non-linear Autoregressive Distributed Lag (P-NARDL) technique, the assessment of cause-and-effect relationship revealed a long-term relationship between variables. Positive asymmetric shock in innovations in sustainable energy technologies positively affects decarbonization, while the negative asymmetric effect is insignificant. The findings indicate that clean energy has a negative consequence on carbonization, whereas economic growth is significantly and favorably associated with it. Furthermore, the study suggests bidirectional causation among all variables except for the unidirectional causality from the usage of sustainable energy technology to CO2 emissions. In a global context, the research recommends governments to reform patenting regulations to identify the roles of new sustainable energy technologies and rectify environmental damages.

Summary: This study examines the effects of economic and financial disruptions caused by the COVID-19 pandemic on food sales in the United States from January 2020 to January 2021. The researchers use the US weekly economic index (WEI) as a measure of economic disruptions and the Chicago Board Options Exchange volatility index (VIX) to capture broader stock market disruptions. Testing a range of models, including autoregressive distributed lags (ARDL), new emerging autoregressive distributed lags (NARDL), and quantile autoregressive distributed lags (QARDL), the researchers validate the NARDL model. The study suggests that an increase in WEI has a significant negative long-term impact on food sales, while a decrease in WEI has no statistically significant (long-run) effect. Therefore, policy responses that neglect asymmetric effects and hidden cointegration may hinder food security during pandemics.

Summary: This study evaluates and compares the growth of green finance through green bond issuance in different countries, and also assesses the impact of this growth on the dependence on fossil fuels. By using the entropy technique and constructing empirical models, it is found that there is a negative correlation between green finance growth and dependence on fossil fuel consumption. The results suggest that the proliferation of green finance instruments can reduce reliance on fossil fuels and facilitate the transition towards a carbon-negative world.
