Does the Three-Year Action Plan for Winning the Blue Sky Defense Battle implementation enabling the high-quality development of regional energy? A quasi-natural experiment from China

Energy is the lifeline of modern economy and industrial development. Promoting the high-quality development of regional energy is an important step to achieve high-quality economic and social development. This paper takes the energy policy of the Three-Year Action Plan for Winning the Blue Sky Defense Battle (the Blue Sky Defense Battle) in China as a quasi-natural experiment, and builds a two-way fixed effects difference-in-differences (DID) model to explore the impact of this policy on the high-quality development of regional energy based on the panel data of China's 31 provinces from 2015 to 2021. The results show that the Blue Sky Defense Battle has a significant positive effect on regional energy high-quality development, and this conclusion is robust under a series of robustness tests. Heterogeneity analysis indicates that the Blue Sky Defense Battle has a more promote effect on the high-quality development of regional energy in the western and eastern region, as well as in the low and middle income provinces. Mechanism analysis reveals that the Blue Sky Defense Battle promotes the high-quality development of regional energy by improving the level of scientific and technological innovation. Nonlinear analysis verifies that there is a single threshold effect of the level of scientific and technological innovation, the influence of the Blue Sky Defense Battle on the regional energy high-quality development becomes stronger when the scientific and technological innovation level above the threshold. The study provides a reference for policy makers to support the implementation of energy policies such as the Blue Sky Defense Battle and enhance the high-quality development level of regional energy.

Consumer Motivations for Solar Energy Adoption in Economically Challenged Regions

This study aims to investigate the factors contributing to and affecting consumer behavior toward renewable energy by following the theories of reasoned action and planned behavior. For this reason, a quantitative research method was employed and primary data were collected via a questionnaire, resulting in a random sample of 450 respondents. Structural equation modeling (SEM) revealed that concern for environmental commitment positively affects attitudes toward solar energy (β = 0.272, p < 0.001), positive subjective norms toward environmental commitment positively influence attitudes (β = 0.092, p < 0.001), perceptions of solar energy values significantly shape attitudes (β = 0.533, p < 0.001), social influence also plays a role in shaping attitudes (β = 0.047, p < 0.001), and that regulations (behavioral control) have a negative impact on attitudes (β = −0.204, p < 0.001). A positive attitude toward solar energy strongly predicts purchase intention (β = 0.944, p < 0.001). The overall model highlights the direct influence of attitude on buying intention and underscores the roles of environmental concern and functional utility in shaping consumer attitudes. This study contributes to the existing literature on renewable energy adoption by providing empirical evidence on the factors influencing consumers’ attitudes toward solar energy systems. By identifying key predictors, the study offers valuable insights into how these elements shape consumer attitudes and subsequent purchase intentions. Additionally, the study enhances the understanding of the role of positive attitudes in driving investment in solar energy, thereby contributing to both theoretical frameworks and practical applications in energy policy and marketing strategies.

Sustainable energy transition, knowledge co-creation and trade: the case of EU residential energy efficiency

ABSTRACT The European Union (EU) sustainable energy transition requires radical changes of economic, technological, societal and political systems. This paper empirically investigates the relationships among environmental policy, innovation and technological capabilities, and economic performances, in terms of country export competitiveness, focusing on residential energy efficiency goods, a core pillar of the EU energy and climate strategy. We combine network analysis with a gravity model to investigate the evolution of the EU bilateral trade and co-patenting activities from 1990 to 2015, based on a panel of 19 European countries. Our results show that the technological skills of the exporting country, related to the production of the households’ energy-consuming appliances, strongly enhance its export performances, and this effect is stronger when countries are EU members. Cooperation in knowledge creation and institutional proximities between trade partners are further key determinants of export performances of analysed countries.

Energy Diplomacy of Turkmenistan: Determining Factors and Legal Framework

Introduction. Energy diplomacy is an effective means of ensuring energy security (international and national) and, at the same time, an instrument for implementing the foreign energy policy of states. Since energy diplomacy is formed and implemented in the conditions of the state legal and international legal environment, the study of its legal component acquires not only theoretical, but also important practical significance. At the same time, the legal aspects of energy diplomacy (both in general and in relation to specific countries) have not yet been systematically developed in the legal literature, including in the science of international law. Based on the analysis of scientific and regulatory material, the article identifies the features of Turkmenistan's energy diplomacy and its legal support.Materials and methods. Within the framework of the study, the sources of international law related to the topic under consideration, political and legal policy documents and acts of national legislation of Turkmenistan are considered. The theoretical basis of the research was the scientific works of experts in the field of international law and energy law, as well as individual studies of the problem of energy diplomacy, including in relation to a chosen country. The methodological basis of the study was presented by general scientific and special legal methods.The results of the study. Factors of a resource-geographical nature, combined with factors of a political and legal nature (the status of Turkmenistan as a permanently neutral state) determine the originality of foreign energy policy and, significant from the point of view of international law, the features of Turkmenistan's energy diplomacy. The main strategic priority of Turkmenistan's energy diplomacy is to increase the export potential of oil and gas products and, in this regard, to create an extensive, modern and efficient infrastructure for transit and delivery of energy resources to foreign energy markets, comprehensive legal support for these processes. Reliance on the potential of multilateral diplomacy (primarily in the UN system) for the international legal legitimization of their national interests in the energy sector is combined with the development of bilateral international legal relations of energy cooperation on terms of mutual benefit, while respecting the basic principles of international law. The head of state plays a special role in the development and legal formalization of Turkmenistan's energy diplomacy. Embargoes, as well as unilateral restrictive measures, used in the practice of a number of States and individual integration associations, are not used as a means of economic pressure on other States. Special importance is attached to preventive diplomacy within the framework of the Central Asian region.Discussion and conclusion. Turkmenistan's energy diplomacy, being the main means of implementing its foreign energy policy, has an international and constitutional legal framework, in turn, including: the UN Charter and other fundamental international legal acts establishing the basic principles of international law and the provisions of the Constitution of Turkmenistan on adherence to these principles, taking into account its permanently neutral status; Resolutions The UN General Assembly and acts of the constitutional legislation of Turkmenistan relating to the legal formalization and implementation of its permanent neutral status; norms of international law and provisions of the constitutional legislation of Turkmenistan regulating the main forms of diplomatic activity; special principles of international energy law correlating with the norms of the constitutional law of Turkmenistan.

From Potential to Power: Advancing Nigeria’s Energy Sector through Renewable Integration and Policy Reform

Nigeria is a nation endowed with both abundant renewable and non-renewable energy resources. Despite its vast potential, Nigeria struggles with a consistent power supply due to various systemic issues, such as inadequate funding, infrastructural decay, corruption, technical skill shortages, and macroeconomic instability. These challenges hinder the effective harnessing and distribution of energy resources, particularly renewable ones like wind, solar, biomass, and hydropower. This study assesses the existing energy policies and their efficacy in promoting sustainable energy development towards achieving universal electricity access by 2030. It highlights the necessity for a just energy transition that integrates a substantial proportion of renewable energy into the national grid, aiming to meet up to 60% of the country’s energy demands with clean sources by 2050. This transition is critical not only for energy security and reducing the environmental impact but also for fostering socioeconomic equity. Recommendations include overhauling the legal and regulatory frameworks to support renewable energy growth, particularly in off-grid areas, to ensure clean, affordable, and secure energy access. Strategic investments, enhanced infrastructure, and robust public–private partnerships are essential to overcome the current barriers and realize Nigeria’s energy potential. This paper calls for a comprehensive approach that addresses both the technical and socioeconomic dimensions of the energy crisis, laying the groundwork for a sustainable and prosperous energy future for Nigeria.

Comparison of Trends in Sustainable Energy Development in the Czech Republic and Poland

The contemporary process of economic development necessitates a heightened focus on matters of sustainability, with a particular emphasis on sustainable energy policy. This is of paramount importance for the protection of the natural environment and the achievement of long-term economic growth. In the context of countries such as the Czech Republic and Poland, which have historically relied on high-carbon energy sources, the transition to a more sustainable energy system represents a significant challenge. The objective of this paper is to undertake a comparative analysis of the trends in energy sustainability in the Czech Republic and Poland from 2017 to 2021, with a particular focus on key performance indicators. The analysis, based on data from the OECD database, revealed notable discrepancies in the rate of change between the two countries, with Poland exhibiting a more pronounced surge in the proportion of renewable energy sources (RES). A Student’s t-test confirmed the existence of statistically significant differences in key indicators between the Czech Republic and Poland, thereby underscoring the diverse challenges that both countries encounter in their pursuit of sustainable energy development. The Granger causality test was employed to ascertain whether variables exhibit temporal relationships that may suggest potential correlations. However, it is important to note that this test does not prove direct causality, but rather indicates that the variables are related at a specific point in time. Interpretation of the results must be undertaken with caution, as the test does not account for the full complexity of relationships between variables, including external factors and structural changes in the economy. Meanwhile, the LMDI decomposition analysis identified the principal drivers of alterations in CO2 emissions. The findings indicate that, despite advancements in sustainable energy development, Poland and the Czech Republic are confronted with distinctive challenges that necessitate the implementation of tailored policy responses. It is therefore recommended that further investment in renewable energy and the modernisation of energy infrastructure be made in order to achieve long-term sustainability goals.

Solar Energy Resource and Power Generation in Morocco: Current Situation, Potential, and Future Perspective

The world’s attention is currently focused on the energy transition to sustainable energy. The drive to reduce greenhouse gas emissions in order to limit global warming, energy security, and the generalization of access to energy have contributed to the adoption of the Moroccan Energy Strategy, with a strong focus on renewable energy (RE). Morocco is notoriously poor in conventional primary fossil energy resources, with energy dependence on the order of 90%. In addition, the energy crisis that resulted from the COVID-19 pandemic and geopolitical conflicts, compounded with steady increase in demand, has heavily affected the security and stability of the country’s energy situation. The transition to RE by strongly engaging in the implementation of several solar, wind, and hydro energy projects has made the country the leader in RE in Africa. These projects benefit from the country’s excellent solar and wind energy potential. As a consequence, by 2030, the share of RE in the installed capacity is expected to reach 52%. An overview of the current situation of RE (particularly solar energy) in Morocco is provided, including the potentials, obstacles, challenges, and future perspectives. Thanks to its high solar potential, it is predictable that Morocco’s effort will be focused on this field: the Erasmus plus INNOMED project is a virtuous example of international cooperation, aiming at promoting solar energy through capacity building and the creation of solar energy networks, in synergy with EU Partners.

The contribution of clean energy consumption and production to sustainable economic development: New insights from the PSTR model

Massive consumption of fossil fuels has posed significant threat to sustainable development. Therefore, clean energy is an urgent requirement for sustainable economic development (SED). There is no comprehensive assessment of the relationship between clean energy and the SED, signifying a research gap in understanding the non-linear effects between them. This study fills this gap by calculating the SED index for China and using a panel smoothed transformation regression model. The findings reveal that the impact of clean energy development and utilisation on SED is characterised by non-linearity, which manifests in two key aspects: (1) Clean energy consumption (CEC) positively influences SED, with its impact strengthening alongside improvements in industrial structure optimisation and economic growth. Notably, the threshold values for the industrial optimisation level, industrial structure level, and economic development are 1.0390, 0.4667, and 43730, respectively. (2) The relationship between clean energy production (CEP) and SED follows a U-shaped curve; once economic development surpasses 38,588 units, CEP transitions from a negative to a positive influence on SED. This study provides valuable insights into comprehensive measurement of SED, offering guidance for countries worldwide to formulate context-specific energy policies aligned with their respective industrial structures and stages of economic development to foster SED growth.

The Path Driving China’s Energy Structure Transformation from the Perspective of Policy Tools

Combing through Chinese energy-related policy texts and exploring the development path of energy restructuring are significant steps towards a better understanding of the history of energy restructuring in the process of building a moderately prosperous society in all aspects. To explore the various paths driving the transformation of China’s energy structure, the energy policies promulgated at the national level from 2001 to 2020 in China were systematically compiled. Based on the policy tool perspective, a theoretical framework for influencing China’s energy structure transition was proposed in three dimensions: objectives, tools, and intensity. A total of 39 national energy policy texts were analyzed using a fuzzy set qualitative comparative analysis method. The results show that (1) the consistency levels of individual preconditions were all below 0.9, which does not constitute a necessary condition for the transformation of China’s energy structure; (2) the sufficiency analysis identified three paths of China’s energy structure transformation, which can be described as models driven by “multiple objectives + information”, “single objective + information”, and “single objective”; (3) energy restructuring is a goal-oriented process; the clarity and certainty of the efficient and green objectives of energy policies have a facilitating effect on energy restructuring, and the support of information technology provides an important guarantee for energy restructuring; (4) compared with European and American countries, it was found that China’s energy policy tools were characterized by an emphasis on macro-planning, insufficient connectivity, and marked tendencies in practice.

Scalar orientation of policies and technology legitimacy: The case of decarbonization in Norway

This paper suggest that we need to better understand the relationship between policy rationales and their scalar orientation. The former refers to the underlying motivations for proposing policies. The latter refers to two dimensions: the geography of challenges that policy seek to address, and the geography of effects that policy seek to instigate. Such variations in the scalar orientation of national level climate and energy policy, may lead to differing rationales for (not) supporting technologies that can contribute to decarbonization, depending also on their alignment with broader context structures. In this way, scalar orientation of policy rationales may have significant implications for technology legitimacy. We develop a conceptual framework that distinguishes four types of scalar orientation in local/global challenges and effects. Empirically, we analyse how shifting scalar orientation of policy rationales in Norway has influenced legitimacy for LNG in shipping, offshore wind in the energy sector, and CCS for various user sectors.

Supporting energy policy research with large language models: A case study in wind energy siting ordinances

The recent growth in renewable energy development in the United States has been accompanied by a simultaneous surge in renewable energy siting ordinances. These zoning laws play a critical role in dictating the placement of wind and solar resources that are critical for achieving low-carbon energy futures. In this context, efficient access to and management of siting ordinance data becomes imperative. The National Renewable Energy Laboratory (NREL) recently introduced a public wind and solar siting database to fill this need. This paper presents a method for harnessing Large Language Models (LLMs) to automate the extraction of these siting ordinances from legal documents, enabling this database to maintain accurate up-to-date information in the rapidly changing energy policy landscape. A novel contribution of this research is the integration of a decision tree framework with LLMs. Our results show that this approach is 85 to 90 % accurate with outputs that can be used directly in downstream quantitative modeling. We discuss opportunities to use this work to support similar large-scale policy research in the energy sector. By unlocking new efficiencies in the extraction and analysis of legal documents using LLMs, this study enables a path forward for automated large-scale energy policy research.

The European Green Deal and turbulence for non-member states

The European Green Deal (EGD) has had a significant impact on EU member states. In this article, we examine the extent to which it can also have large consequences for non-members. Based on a qualitative approach comparing Norway and the UK, and drawing on a burgeoning literature on ‘turbulence’, we ask whether the EGD creates turbulence in non-member states, what the nature of this turbulence is, and whether the extent and nature of turbulence varies with how closely affiliated a non-member is with the EU. Despite the ambitious climate policies of both countries, we identify a significant amount of turbulence generated by the EGD. Interestingly, we also find that turbulence increases with a closer EU-affiliation. However, our analysis also reveals an impressive capacity in both countries to adapt to their turbulent conditions, and a surprising durability of climate and energy policy in the face of turbulence.

Template-synthesized CdWO4/Cd0.5Zn0.5S hollow microsphere photocatalyst for high-efficient hydrogen evolution under visible light

Photocatalytic water splitting for hydrogen production is a promising strategy for renewable energy. While Cd1-XZnXS catalysts display high photocatalytic hydrogen evolution efficiency in pure water, they are limited by severe photocorrosion and rapid recombination of electron–hole pairs. In this study, HGM (hollow glass microspheres) was used as the support template, Cd0.5Zn0.5S and CdWO4 were successively coated on the template by hydrothermal method. The tightly packed heterojunction interface between the coatings ensures efficient electron transport and suppresses the recombination of electron-hole pairs. Under visible light irradiation, when the theoretical mass ratio of Cd0.5Zn0.5S to CdWO4 is 4:1, the Cd0.5Zn0.5S/CdWO4-25% hollow microsphere photocatalyst exhibits the highest hydrogen evolution rate, reaching 41.40 mmol g−1 h−1, which is approximately 3.4 times higher than the hydrogen evolution rate of pure Cd0.5Zn0.5S (12.31 mmol g−1 h−1). This research provides a novel approach for the design and synthesis of efficient and stable photocatalysts.

Impact of urbanization, economic growth, FDI, and trade openness on energy demand in Ireland: An ARDL approach

Abstract This research study uses an autoregressive distributed lag (ARDL) paradigm to examine the effects of trade openness, urbanization, economic growth, and foreign direct investment (FDI) on energy demand in Ireland. This thorough theoretical framework anticipates a relationship between energy demand and trade, foreign direct investment, and urbanization. This study demonstrates both short- and long-run cointegration among the variables employing an ARDL (autoregressive distributed lag) bounds-testing method for the data set period from 1972 to 2021. Additionally, Fully Modified Ordinary Least Square (FMOLS), Dynamic Ordinary Least Square (DOLS), and Canonical Cointegrating Regression (CCR) were utilized in the study to verify the results' robustness. Nonetheless, this analysis discovers that trade openness and rising GDP (Gross Domestic Product) per capita increase energy consumption. The results show that for every 1% increase in GDP, energy consumption increases by 0.967%. On the flip side, energy consumption in Ireland is declining due to increased urbanization and foreign direct investment. The results show that for every 1% increase in urbanization, energy usage decreases by 1.738%. The investigation shows that Ireland's energy usage is strongly impacted by trade liberalization, FDI, urbanization, and economic expansion. Findings like these can help policymakers and stakeholders manage and optimize energy usage in the context of urbanization, economic expansion, foreign direct investment, and global trade. The report recommends sustainable energy planning and policy initiatives to strike a healthy balance between meeting the increasing demand for energy and protecting the environment.

Identification of optimal waste-to-energy strategies for sustainable development in Iran: SWOT analysis, hybrid MCDM methods, and game theory

The growing global focus on environmental sustainability and the pressing need for efficient waste management and energy crisis mitigation have prompted extensive investigations into sustainable waste management strategies. Given Iran's economic development and population growth, the country faces challenges in energy supply and waste management, making waste-to-energy (WtE) applications a promising solution for sustainable waste management. This study employs a combination of SWOT (Strengths, Weaknesses, Opportunities, and Threats) analysis, Multi-Criteria Decision-Making (MCDM) approaches, and game theory to explore WtE technologies and processes, evaluate their applicability within Iran's context, and identify the most effective WtE strategies for the country. Furthermore, game theory and fuzzy Shapley value analysis were utilized to determine the optimal combination of WtE development strategies. The strategy player “SO” held the highest position of power, with a fuzzy Shapley value of (0.391, 1.744, 3.264), resulting in the identification of the optimal strategy combination of SO2ST2WO1WT2, with a value of (0.429, 0.679, 0.893). The recommended combination emphasizes landfill with gas capture, development of incineration power plants, and integrated resource recovery through residue-derived fuel (RDF) implementation. Achieving these objectives necessitates energy policy reforms, pricing adjustments, improvements in the energy subsidy system, and infrastructure and market development.

Natural Gas Consumption Forecasting Based on Homoheterogeneous Stacking Ensemble Learning

Natural gas consumption is an important indicator of energy utilization and demand, and its scientific and high-accuracy prediction plays a key role in energy policy formulation. With the development of deep neural networks and ensemble learning, a homoheterogeneous stacking ensemble learning method is proposed for natural gas consumption forecasting. Firstly, to obtain the potential data characteristics, a nonlinear concave and convex transformation-based data dimension enhancement method is designed. Then, with the aid of a stacking ensemble learning framework, the multiscale autoregressive integrated moving average (ARIMA) and high-order fuzzy cognitive map (HFCM) methods are chosen as the base learner models, while the meta learner model is constructed via a well-designed deep neural network with long short-term memory (LSTM) cells. Finally, with the natural gas energy consumption data of national and 30 provinces (where the data of Xizang are unavailable) of China from 2000 to 2019, the numerical results show the proposed algorithm has a better forecasting performance in accuracy, robustness to noise, and sensitivity to data variations than the seven compared traditional and ensemble methods, and the corresponding model applicability rate could achieve more than 90%.

Nuclear Energy as a Sustainable Source? Examining Media Discourses Surrounding the EU-Complementary Delegated Act

This paper contributes to the understanding of media discourses surrounding the sustainability of nuclear energy, particularly within a crisis context. The study examines the implications of the adoption of the Complementary Delegated Act on EU taxonomy by the European Commission on July 6, 2022, which officially categorises nuclear energy as sustainable. Employing a critical discourse analysis (CDA) methodology, the research explores the discourse strategies–nomination, predication, and argumentation– utilised across 695 news articles. The findings reveal the intricate representation of nuclear energy’s sustainability across the media. The Russian-Ukrainian conflict amplifies favourably the nuclear energy view as a reliable and sustainable energy source. However, the media discourse on nuclear energy’s sustainability reveals a variety of viewpoints. These varying outlooks provide essential insights for shaping effective energy policies. This research contributes valuable insights into understanding how media shapes and influences public perception of sustainability energy policies, amplifying specific actors’ voices and steering discourse toward distinct trajectories. Such insights are crucial in crafting energy policies.

The anchoring policy perspective on policy change: mechanisms, applications and analytical challenges

ABSTRACT How functional relationships between policies influence policy design and policy change has received relatively limited attention within public policy scholarship despite the importance of policy coordination. This article contributes to addressing this gap by introducing the Anchoring Policies Perspective (APP), a framework for analysing interactions between policies in functional policy hierarchies. The APP examines how formal links between anchoring policies (AP) and functionally subordinate policies (SP) generate anchoring effects, whereby the provisions codified in APs generate alignment pressures that channel the design of SPs towards the norms and goals of the AP. In the article, we examine the analytical contribution of the APP by analysing the distinguishing characteristics of APs, the mechanisms through which APs influence SP introduction and design, and political strategies for managing situations where resistance occurs to the alignment of SPs with their APs. Examples from environmental and energy policy are used to illustrate key features of the AP-SP relationship, following which the APP’s contribution to public policy scholarship is discussed. We conclude by arguing that the APP has the potential to bring important new insights to the analysis of policy change while building connections with established theories of policy change to develop the APP framework further.
