Nexus among green energy consumption, foreign direct investment, green innovation technology, and environmental pollution on economic growth

An assessment on the new impetus of green energy development and its impact on climate change: a non-linear perspective

The purpose of this article is to investigate the new driving forces behind China's green energy and further assess the impact of green energy on climate change. The existing literature has used linear methods to investigate green energy, ignoring the non-linear relationships between economic variables. The nonparametric models can accurately simulate nonlinear relationships between economic variables. This paper constructs a nonparametric additive model and uses it to explore green energy. The empirical results show that the impact of green finance on green energy is more prominent in the later stage (a U-shaped impact). Fiscal decentralization also exerts a positive U-shaped impact, meaning that expanding local fiscal autonomy has contributed to green energy growth in the later stage. Similarly, the impact of oil prices and foreign direct investment demonstrates a positive U-shaped pattern. However, the nonlinear impact of environmental pressure displays an inverted U-shaped pattern. Furthermore, this article explores the impact of green energy on climate change and its impact mechanisms. The results exhibit green energy generates a positive U-shaped impact on climate change, meaning that the role of green energy in mitigating climate change gradually becomes prominent over time. Mechanism analysis exhibits that industrial structure and energy structure both produce a nonlinear influence on climate change.

Sectoral foreign direct investment and environmental degradation: new insights from diversification of energy mix containing fossil fuels and renewable energy

The objective of the study is to extend the existing literature by investigating the effects of foreign direct investment, gross domestic products and per capita and energy diversification on the nitrogen oxide emissions in Brazil, Russia, India, China and South Africa (BRICS) by using annual data during the period 1992-2019. As per our knowledge, the present study is a first of its kind to examine the impact of a new energy diversification index, based on Herfindahl-Hirschman framework on pollution. This study has adopted a new quantile regression augmented method of moments, which is capable of producing the total impacts of the independent variables across the entire distribution of nitrogen oxides emissions. The findings suggest that an increase in foreign direct investment leads to a decrease in nitrogen oxides emissions at the aggregate level and in both manufacturing and service sectors. We observe that foreign direct investment leads to an increase in nitrogen oxides emissions in the agricultural sector in most of the quantiles. Diversification towards renewable energy causes a decrease in nitrogen oxides emissions in most quantiles at aggregate level, agricultural and manufacturing sectors, whilst diversification leads to an increase in nitrogen oxides emissions in the service sector. The findings also suggest that GDP per capita leads to an increase in NOx emissions in all the quantiles. The study suggests the policy to use and attract more clean energy through foreign direct investment for towards the achievement of sustainable development.

Does environment quality affect the health care spending? Nexus among CO2 emissions, non-renewable energy production, financial development, and health care spending

This study investigates the dynamic associations among carbon dioxide (CO₂) emissions, non-renewable energy production from petroleum derivatives, financial development, and healthcare expenditures to improve environmental quality. This research has employed the balanced annual panel of thirty (30) Organizations for Economic Co-operation and Development (OECD) countries' data set and applied panel vector autoregression (VAR) method depending on the generalized method of moments (GMM). Furthermore, the empirical findings reveal that health spending and CO₂ emissions have a favorable bidirectional link, but there is no indication that health spending promotes power generation. The results demonstrate that increased energy consumption and productions affect pollution, and higher CO₂ emissions increase healthcare costs. Whereas, energy consumption, financial development, and healthcare expenditures have a positive toward environmental quality.
