Causal interactions between environmental degradation,renewable energy,nuclear energy and real GDP: a dynamic panel data approach

Renewable energy as well as nuclear energy are low carbon power that presents the life cycle emissions of greenhouse gases than fossil fuel energy. However, analyzing the relationship between the consumption of renewable energy, consumption of nuclear energy, CO₂ emissions and economic growth is crucial for the economic and energy policy decision; we address this question for developed countries. This paper deals with the relationships between nuclear energy, environmental degradation, real GDP and renewable energy. We apply a panel data model for a global panel consisting of nine developed countries during the period 1990–2013. The group studied consists of Canada, France, Japan, Netherlands, Spain, Sweden, Switzerland, UK and the USA. The empirical findings suggest that: (1) a causal link between emissions and real income, (2) a unidirectional causality running from renewable energy to nuclear energy, (3) a unidirectional causal relationship running from capital to environmental degradation, (4) a unidirectional causal relationship running from income to nuclear energy consumption, since the growth hypothesis is valid, (5) a unidirectional causality running from capital to income, (6) no an outstanding role of renewable energy use in the contribution of CO₂ emissions.     

The effect of clean energy regulations and incentives on green jobs: panel analysis of the United States, 1998–2007

‘Green jobs’ are often presented as a simultaneous solution for the economic downturn and the environmental crisis, particularly as they relate to sustainable development in energy and climate change. Federal, state, and municipal authorities have employed a variety of policy tools to boost job creation within their jurisdictions. This study focuses on the role that state policies play in creating green jobs. It examines two generic policy tools – regulations and incentives – each of which can be aimed at advancing energy efficiency or renewable energy production, and assesses the relative impact they have had on generating green jobs. In order to measure this impact, we utilize panel data compiled by the Pew Charitable Trusts, which contain a state‐level count of green jobs from 1998 to 2007. The results of the analysis suggest that regulations, particularly those that mandate action on renewable energy, are likely to increase the number of private sector green jobs in states. Regulations with clear guidelines and targets tend to reduce uncertainty in business, and can lead to increased private sector investment and job availability. This study provides practical lessons regarding the type and design of policy instruments and regulations on renewable energy, which effectively encourage green job growth.     

Income,environmental considerations,and sustainable energy consumption in Africa

Evidence on income as a crucial driver of renewable energy consumption in Africa is mixed. But hydropower accounts for over 90% of renewable energy in sub-Sahara Africa alone. Yet, empirical evidence suggests that hydropower may not be as environmentally sustainable as believed and, as a legacy source of energy in Africa, may not accurately reflect attitudes on renewable energy motivated by environmental concerns. This paper examines the role played by economic performance in the rising sustainable energy consumption in Africa, focusing on the renewable energy sources that are compatible with sustainable development. The difference generalized method of moments, fully modified ordinary least squares, and dynamic ordinary least squares are employed to estimate the statistical significance of income, environmental sustainability proxy, and prices as important drivers of sustainable energy consumption in a panel of 10 African countries for the period 2000–2011—a time frame characterized by a rapid rise in renewables as a priority in environmental policy. With timing and measurement considerations on sources of renewables, results indicate that in contrast to recent literature, the rise in sustainable energy consumption in Africa is strongly driven by rising domestic incomes. In line with literature, however, there is a generally positive, albeit statistically insignificant relationship between sustainable energy consumption and levels of carbon emissions. Oil prices in real terms also correlate with sustainable energy consumption. Available data also show that countries with low energy security also coincidentally tend to have high small hydropower capacity, providing potential for sustainably reducing energy insecurity.     

The decline of environmental degradation by renewable energy consumption in the MERCOSUR countries: an approach with ARDL modeling

The impact of consumption of renewable energy on CO₂ emissions was investigated, in five MERCOSUR’s countries from 1980 to 2014. The autoregressive distributed lag (ARDL) in the form of Unrestricted Error Correction Model to decompose the total effect of variables into it is the short- and long-run components. The results of preliminary tests showed the presence of cross-sectional dependence between the variables, the stationarity of all variables in the first differences, and the homogeneity in panel data. Moreover, the specification tests pointed to the presence of cross-sectional dependence, non-correlation between the crosses, serial correlation in the panel data model, and the existence of heteroskedasticity. The results of semi-elasticities (short run) and elasticities (long run) of ARDL model pointed that the economic growth and consumption of fossil fuels increase the CO₂ emissions in the short and long run, while the consumption of renewable energy reduces them. Despite the consumption of renewable energy reducing the environmental degradation in the MERCOSUR countries, its impact is small. Finally, this study proved that the consumption of renewable energy is able to reduce the CO₂ emissions, which is responsible for the environmental degradation in the MERCOSUR countries, and that the economic growth of these same countries increases the CO₂ emissions, along with the fact that all MERCOSUR countries are highly dependent of fossil fuels.

Heterogeneous effects of urbanization and environment Kuznets curve hypothesis in Africa

This work explores the heterogeneous effect of urbanization and nonrenewable energy consumption on the environment in 54 African nations. Panel data were used from 1996 to 2019. For estimation, panel quantile regression analysis, augmented mean group, panel threshold regression, and the environment Kuznets curve hypothesis were applied to check the relationship between income and carbon emissions. The study's outcome demonstrates that urbanization and nonrenewable energy consumption degrade the environment in Africa. Furthermore, an inverted U-shape relationship exists between economic growth and CO₂ emissions, confirming the environmental Kuznets curve hypothesis. The findings indicate that urbanization should be planned; otherwise, urbanization can cause environmental degradation. African countries must adopt green urbanization and use renewable energy and clean manufacturing technologies. The institutions are encouraged to execute the standard, regulatory environment, and policies to reduce carbon emissions. Countries throughout the African continent should actively respond to the issues by charting a separate and diverse route for urban development.     

U.S. Electric Utilities and Renewable Energy: Drivers for Adoption

Renewable energy can address rising demand for energy, environmental protection, energy security, and job creation. This paper assesses resource, economic, social, and political drivers for the adoption of renewable energy. Analysis of the data collected from over 100 interviews with utility managers reveals that production tax credits significantly influence the percent of renewable energy in a utility's portfolio. The availability of renewable energy resources, economic drivers, social influences, and political drivers such as renewable portfolio standards and government grants are not significant drivers. Understanding these drivers can help electric utilities, governments, and other stakeholders with their efforts to reap the benefits of renewable energy.     

How renewable energy and service growth influence environmental quality: Evidence from a sustainable development perspective

The present study inspects the relationships between the carbon dioxide (CO₂) emissions, real GDP, renewable and non-renewable energy consumption, as well as the service growth for top ten countries (TTC) in service activities. The empirical modeling used in the study involves the procedures of cointegration and tests of Granger causality to inspect the dynamic interaction between the variables during the period from 1980 to 2018. The results of the present study suggest that the variables are cross-sectionally dependent. In addition, the variables appear to be cointegrated based on several tests. The long-run outcomes revealed an inversed U-shaped form between emissions-GDP proving the validity of the environmental Kuznets curve assumption. The fully modified ordinary least squares and dynamic OLS estimates show that the non-renewable energy and economic growth contribute to the increase of CO₂ emissions, while service value-added leads to decrease emissions. Furthermore, the renewable energy coefficient comes through as negative but insignificant for the selected panel. The TTC in service should stimulate the usage of renewable energy in various service events for following the path of sustainable development. Devising the investment plans associated with the use of renewable energies is quite essential for the advancement of the service sector leading to mitigating emissions portion.     

A multi-criteria framework to assess the sustainability of renewable energy development in the Alps

A multi-criteria analysis (MCA) was implemented to assess the best solutions for enhancing the production of renewable energy in the Alps. A set of criteria were selected based on the impacts of four renewable energy sources (forest biomass, hydropower, ground solar photovoltaic and wind power) on the three spheres of sustainability (environmental, social and economic). Three different scenarios are presented, each with a different set of weights for the criteria: the first scenario considers equally all three aspects of sustainability; the second scenario foresees an environmentally-oriented perspective, while the third scenario is more focused on the socio-economic aspects related to the development of renewable energy. Results show that forest biomass and hydropower seem to be the most viable solutions for enhancing the share of renewable energy in the Alps. Ground solar photovoltaic and wind power, on the other hand, seem to be less attractive alternatives due to their high impacts on land use.     

Assessing Major Ecosystem Types and the Challenge of Sustainability in Turkey

In recent years, Turkey has experienced rapid economic and population growth coupled with both an equally rapid increase in energy consumption and a vast disparity in welfare between socioeconomic groups and regions. In turn, these pressures have accelerated the destruction of productive, assimilative, and regenerative capacities of the ecosystems, which are essential for the well-being of the people and the economy. This paper describes the structure and function of major ecosystem types in Turkey and discusses the underlying causes of environmental degradation in the framework of economy, energy, environment, and ethics. From a national perspective, this paper suggests three sustainability-based policies necessary for Turkey's long-term interests that balance economic, environmental, and energy goals: (1) decoupling economic growth from energy consumption growth through the development of energy-efficient and renewable energy technologies; (2) linking economic efficiency and distributive justice of wealth and power through distributive and participatory public policies; and (3) integrating the economic and ecological systems through the internalization of externalities and ecosystem rehabilitation.     

Nexus between renewable energy consumption,economic growth,and CO2 emissions in Algeria: New evidence from the Fourier-Bootstrap ARDL approach

Governments often impose new energy strategies to support new CO₂ emission-reducing technologies without affecting economic growth. Hence, this study aims to re-investigate the relationship between economic growth, renewable energy use, and CO₂ emissions in Algeria from 1990 to 2018. Motivated by the mixed findings of the existing literature, which ignore the Fourier function and bootstrap test and apply the newly developed Fourier bootstrap autoregressive distributed lag model (FARDL). Our findings indicate that renewable energy use and growth have a long-run relationship with CO₂ emissions and do not accept the existence of the Environmental Kuznets Curve (EKC) hypothesis for CO₂ emissions in Algeria. In the long term, the results show that renewable energy use has a negative and significant impact, and growth has a positive and statistically significant effect on CO₂ emissions. In the short run, the findings indicate that renewable energy use reduces CO₂ emissions, while both the growth and squared growth had positive and statistically insignificant impacts on CO₂ emissions, confirming the lack of evidence supporting the EKC hypothesis. Moreover, the causality test indicates a one-way causation from growth to renewable energy use, confirming the conservation hypothesis for Algeria and from growth to CO₂ emissions. Interestingly, we found one-way causality from CO₂ emissions to renewable energy use, attributing this to the fact that renewable energy usage has yet to reach a point that it can significantly cause a CO₂ emissions reduction. Based on the results, we recommend that policymakers design appropriate policies to decarbonize energy consumption, e.g., increasing fossil fuel costs and implementing a carbon tax. In contrast, Algeria should promote new CO₂ emission-reducing technologies without affecting economic growth, e.g., tax exemptions and reductions for enterprise owners in the renewable energy industry.     

The global partnership for sustainable development

This paper examines whether foreign aid, together with other economic, social and environmental factors, contributes to sustainable development. It starts with an illustrative theoretical growth model where foreign aid promotes sustainable development by protecting the environment. Using factor analysis and newly developed estimation methods for a dynamic panel data model with endogenous regressors, the empirical section of the paper finds evidence that foreign aid has had a significantly positive influence on sustainable development in aid recipient countries. This effect is very likely to go through channels related to growth and resources as well as a technology channel with respect to energy intensity. This research has important implications for a post‐2015 development framework on international collective action with regard to a sustainable future.

Indicators for sustainable energy development in Mexico

This article presents a summary of a study on the application to the Mexican energy sector of a core set of indicators for sustainable energy development (ISED), developed by the International Atomic Energy Agency (IAEA). The study focused on the elaboration of socio‐economic and environmental indicators related to energy production and use, and was aimed at assessing Mexico's existing energy policies and identifying strategies and possible policies that could bring about improvements in major priority areas: energy intensity, atmospheric emissions, energy import dependency and use of renewables. While positive trends have been observed in relation to energy intensity and atmospheric emissions, Mexico is becoming more dependent on imports of gasoline, natural gas and other high‐value secondary energy sources, while exporting significant amounts of primary fuels, such as crude oil. Also, no significant increase has been observed in the use of renewable sources of energy. Social, economic and environmental policies need to be formulated for the energy sector and related investments (public and private) reinforced so that all economic sectors have access to energy from cleaner and more diverse sources.     

Energy for sustainable development: Review of national and international energy policies

This article presents an assessment of the effectiveness of national and international energy policies directed toward the objectives of sustainable development contained in Agenda 21. Following a brief overview of energy and transport sector trends over the past ten years, the article discusses whether and to what extent energy policies for sustainable development have impacted on poverty reduction, energy security, equitable access to energy, and transition to a more efficient and environmentally sound energy system.
The impact of policies is assessed considering that such a transition involves appropriate combinations of energy efficient technologies and usage patterns, wider use of renewable energy, and gradual induction of advanced energy technologies. The article then examines the extent to which such policies have been based on integrated assessments of the needs and priorities in economic growth, social development and environmental protection and identifies some of the main constraints and barriers hampering the implementation of energy for sustainable development. The article also examines whether decision-making processes ensure multi-stakeholder participation in policy development and support a fair sharing of commitments, responsibilities and benefits among the participating stakeholders in policy implementation. Selected case studies of policies that have made a tangible difference in promoting energy for sustainable development are outlined.
Finally the article discusses the challenges facing energy for sustainable development and discusses various options to accelerate the implementation of its goals.     

Evaluation of energy policy in Cuba using ISED

This article discusses the development of Cuba's energy sector in the last half century, especially the last 25 years, emphasizing social, economic, environmental and institutional aspects. Energy use is evaluated with the indicators for sustainable energy development (ISED) developed by the International Atomic Energy Agency (IAEA) and applied by the authors, based on data series from Cuba's National Office of Statistics. Cuba's economy and energy sector have undergone important changes, particularly in the 1990s during the crisis that resulted from the termination of the country's special trade relations with former socialist countries. Based on an analysis of Cuba's economy and energy situation, a number of policies were selected for evaluation, including those aimed to reduce energy import dependence, increase the share of renewable energy sources and improve energy efficiency. The effects of these policies are evaluated in view of sustainable energy development. The article concludes with an evaluation of recent progress towards sustainable energy development in Cuba, and outlines future options for the country.     

Disaggregated energy consumption,environment, and economic growth nexus of emerging South and East Asian Countries: An ARDL approach

This study examines the nexus between disaggregated energy consumption (EC), CO₂ emissions, and economic growth in emerging South and East Asian countries over the period of 1994 to 2019. The long-run equilibrium relationship is determined by using the “Autoregressive distributed lag (ARDL) model” and the “Generalized least square (GLS) technique.” The panel causality test developed by “Dumitrescu and Hurlin, 2012” determines the direction of causation between variables. Disaggregated EC and CO₂ emissions positively affect economic growth in the research. The PMG estimate also validates the GLS findings, which produce the same results as the PMG estimation. To check the robustness, we also use FMOLS and DOLS estimators. The results confirm the feedback hypothesis for South and East Asian nations regarding energy uses, CO₂ emissions, and economic growth. In contrast, there is unidirectional causality between industrial development and economic growth. These findings will help governments in South and East Asia craft effective energy policy regulations for their financial institutions.

The relationship among economic growth,CO<Subscript>2</Subscript> emissions,and energy use in the APEC countries: a panel VAR approach

The aim of this paper is to analyze the relationship among economic growth, carbon dioxide emissions, and energy use for 19 APEC countries over the 1960–2013 years. Using a panel VAR technique, a three-variable VAR is estimated. Empirical findings illustrate that no causal relationship emerges between real GDP and energy use. Thus, our empirical evidence is in line with the “neutrality hypothesis.” Moreover, panel cointegration tests show that a long-run equilibrium relationship is questionable for the APEC countries. Granger causality analyses confirm our previous results, since in nine countries any causal relationship between GDP and energy is found.
