Exploring the Roles of Renewable Energy, Education Spending, and CO2 Emissions towards Health Spending in South Asian Countries

The effect of environmental degradation on self-reported health: the role of renewable energy consumption

Although there are a number of studies in the literature that have explored the effect of environmental degradation on the subjective well-being and life satisfaction, no previous study has addressed the role of renewable energy consumption in examining the effect of environmental degradation on self-reported health. To this end, we employ a conditional mixed process (CMP) model, using a unique dataset that combines both micro-level data from the 6th (2010-2014) and 7th (2017-2022) Waves of the World Values Survey (WVS) database and macro-level data from the World Bank. Our study has several important empirical findings. First, while environmental degradation deteriorates self-reported health, social capital and health expenditure have a positive impact on self-reported health. Second, the share of renewable energy consumption in total final energy consumption has a statistically significant negative impact on environmental degradation. Third, urbanization has a deteriorating effect on environmental quality and the total number of people increases environmental degradation.

Defining the roles of socio-economic factors and bureaucratic quality to minimize the impacts of fossil fuels consumption on CO2 emissions in G-20 countries

G-20 nations are committed to reducing CO2 emissions considering their commitments to the United Nations. Therefore, this work investigates the associations between bureaucratic quality, socio-economic factors, fossil fuel consumption, and CO2 emissions from 1990 to 2020. To counter the problem of cross-sectional dependence, this work applies to cross-sectional autoregressive distributed lag (CS-ARDL). The valid second-generation methodologies are applied, and the results cannot be found in the environmental Kuznets curve (EKC). Fossil fuels (coal, gas, oil) exert a negative impact on environmental quality. The direct impact of bureaucratic quality and socio-economic factors are suitable to lower CO2 emissions. A 1% increase in bureaucratic quality and socio-economic factors will lower CO2 emissions by 0.174% and 0.078% respectively in the long run. The indirect effect of bureaucratic quality and socio-economic factors is significant in reducing the CO2 emissions created by fossil fuels. The wavelet plots also validate these findings that bureaucratic quality is important to lower environmental pollution in 18 G-20 member countries. Considering the findings, this research presents important policy instruments that there is a need to bring clean energy sources into the total energy mix. For this purpose, it is important to improve bureaucratic quality to speed up the decision-making process for clean energy infrastructural development.

Role of household waste, governance quality, and greener energy for public health: Evidence from developed economies

In the current times, the global economies and international organizations declared that pollution is one of the prominent causes of declined human health. Still, most literature is biased toward economic sustainability and ignores such vital issues. The current study tends to identify the factors affecting public health in the Group of Seven economies except for Italy (G6). Specifically, this study aims to investigate the influence of household waste (HHW), bureaucratic quality (BQ), democratic accountability (DA), urbanization growth (URP), GDP per capita, and renewable energy use (EPR) on public health, throughout 1996-2020. This study uses advanced panel data approaches and finds the heterogeneity of slope coefficients, the dependence of cross-sections, and the persistence of cointegration between the variables. The asymmetric distribution of data leads to employing the novel method of moment quantile regression. The estimated results reveal that URP, GDPPC, and EPR significantly increase domestic general government health expenditures, improving public health. However, HHW and BQ adversely affect public health by reducing health expenditures. The robustness of the results is tested via utilizing the panel quantile regression. Based on the empirical findings, this study suggests policies regarding the improvement in public health expenditure, R&D investment, spending in renewable energy sector, and strengthening of the institutional quality.

Economics of Implementing Solar Thermal Heating Systems in the Textile Industry

This paper analyzes the potential of solar thermal systems for being employed for process heating in cotton-based textile industries. The technological capability of a flat plate collector (FPC) to meet the solar industrial process heating (SIPH) requirement in yarn production is assessed. Moreover, the usability of a parabolic trough collector (PTC) in meeting the technological mandates of SIPH in fabric processing units is critically examined. Further, this paper reports the findings of a study on the potential cost advantage of solar process heating over the conventional process heating practices in cotton-based textile industries. The approach involves the selection of the locations of sample textile industries and the employable solar collector technologies, as well as assessment of financial reward, if any. Eight different cotton-based textile industries located in different geographical domains (in India) are selected. The selected textile industries are situated within the textile hubs existing in different states across India. Analysis of technoeconomic benefit derivable in selected textile industries using FPC for hot water generation and PTC for steam generation is presented. In the case of FPC-based SIPH systems, the maximum value of solar fraction is estimated to be 0.30 and the corresponding estimation for the levelized cost of useful thermal energy (LCUTE) delivered comes out as INR 790/GJ to INR 1020/GJ. On the other hand, in case of parabolic-trough-solar-concentrator-based SIPH systems, LCUTE is estimated in the range of INR 1030/GJ to INR 1610/GJ. From a critical analysis of financial viability in consideration of related factors such as payback time and return on investment in SIPH, it appears that the SIPH systems for hot water generation may be a good choice, whereas SIPH systems for steam generation are seen to have longer payback periods and lower returns on investment, and, therefore, it seems that adequate financial support from central and state governments with additional supports from bilateral or multilateral organizations may enable them to become a sustainable technology option.
