National climate legislation and policymaking and energy security: International evidence

With the shift towards low-carbon economies, energy security has emerged as an increasingly vital concern for governments worldwide, particularly in recent years, because of ongoing conflicts and increased volatility in the international energy market. Both laws and policies are essential tools for mitigating climate change challenges; however, its role in energy security remains unexplored. Drawing on climate-related legislative activities in 127 countries from 2000 to 2021, this study examines the short- and long-term impact of climate laws and policies on energy security performance (ESP). The empirical results demonstrate that both recent and longstanding climate laws and policies have enhanced the national ESP on a global scale. Furthermore, we find that laws outperform policies regarding energy security improvement. Additional analyses indicate that the impact of climate laws and policies on ESP is more effective across high- and upper-middle-income countries, and less effective in low-income countries, especially those in Africa. Our findings highlight the significance of climate legislative efforts and provide important implications for global governments in securing their green transition.

Resource Potential of Socio-Economic Development in the Regional Sustainability Context: the Role of Energy Security and Environment

The current dynamics pose a number of primary tasks for society and the state, related both to the issues of accelerating economic growth and taking into account regional specifics in terms of increasing the requirements for ensuring the sustainability of socio- economic development strategies (SED). This requires ensuring the rational use of regional resources, including the need to maintain energy security (ES) of territories and environmental (EnM) protection. This article studies the interrelationships between the regions’ RP and the main factors of their sustainability: ES and the state of EnM. The purpose of the study is to analyze the impact of ES and the state of EnM on the RP regions in the process of their SED, taking into account the state of sustainability from the strategic perspective. The methodological basis of the study is based on the use of the comparativist approach, which allowed us to consider the factor states of regional sustainability through comparative analysis in order to select common characteristics that affect the RP state. As a result, the authors have formed models aimed at determining the relationship between sustainability factors and RP regions.

How environmental protection activities and industrial revolution contributes in the nexus of energy security and environmental sustainability?

The booming fintech industry seeks to revolutionize traditional financial practices, introducing new business models and innovative applications to enhance financial services. However, the widespread adoption of fintech may lead to increased energy consumption, posing environmental challenges. Comprehensive research is essential to understand the impact of fintech on economies, financial culture, and the environment, facilitating informed decision-making to foster sustainable growth in the sector. Therefore, the present research will explore how the fintech industry, green finance, and energy efficiency play their role in energy security and the achievement of a sustainable environment. The current study used data from 2000 to 2020 by employing Fourier autoregressive distributed lag (ARDL), fully modified least squares (FMOLS), and dynamic ordinary least squares (DOLS) econometric techniques to explore how the industrial revolution, environmental protection activities, and energy efficiency affect energy security and the environment across European countries. According to the findings, the fintech sector encourages the use of eco-friendly and energy-efficient technology, which assists in lowering carbon emissions and boosting energy security and efficiency. The outcomes of energy efficiency show a negative relationship with carbon emissions but a considerably positive relationship with energy security. This research shows that green financing has a favorable influence on energy security, and in European nations, green financing drives the majority of investments made for environmental conservation.

Hilbert Fractal Antenna for Abnormal Discharge Detection of Transmission Equipment

The safe and stable operation of the power system can ensure people’s basic electricity needs. It also plays an important role in energy security and economic development and can contribute to environmental protection and energy conservation. If there are problems in the power system, it will not only affect people’s normal life and work but also lead to power loss or waste, thereby exacerbating the impact on the environment. With the long-term operation of transmission equipment, insulation devices are aging, leading to frequent abnormal discharges and affecting the safety and stability of the power system. Therefore, timely detection and troubleshooting are necessary. When abnormal discharge occurs in transmission equipment, it will radiate radio frequency (RF) electromagnetic waves, which are mainly concentrated between 200 MHz and 300 MHz. RF antennas that can capture signals in this frequency band can be used for detection to determine whether abnormal discharge has occurred. This article uses the Hilbert fractal antenna as the research object to analyze the impact of different orders on antenna performance and optimizes the different feeding point positions of the antenna. Finally, the antenna structure for detecting abnormal discharge is obtained. By making an actual antenna and conducting experimental analysis, the discharge detection function of the designed antenna is verified.

The role of energy security and economic complexity in renewable energy development: evidence from G7 countries.

The development of renewable energy is receiving more attention as a result of environmental degradation and energy instability. Despite a large literature on the nexus between energy security, economic complexity, and energy consumption, there are few attempts to analyze the impact of energy security and economic complexity on renewable energy. This paper examines the heterogeneous impacts of energy security and economic complexity on renewable energy in G7 countries from 1980 to 2017. The estimated results obtained from quantile regression show that energy insecurity is a driving force of renewable sources although its impact is heterogeneous across the distribution of renewables. In contrast, economic complexity hampers the development of renewable energy with the size of impact decreasing as the renewable energy sector progresses. In addition, we find that income positively affects renewable energy while the role of trade openness varies across the distribution of renewable energy variable. These findings lead to valuable policy implications for G7 countries to develop renewable energy.

A comprehensive mechanism for monitoring and preventing threats to sustainable development and energy security of the fuel and energy complex is proposed. Evidence-based proposals have been developed for the efficient and safe sustainable development of the sectors of the energy sector of the national economy.

The causes of risk in fuel supply chains and their role in energy security

Managing risk is of central importance in achieving energy security, yet a methodology for identifying and assessing all relevant risks has previously been lacking. From an extensive review of risk and the operation of fuel supply chains, 34 distinct generic causes of risk have been recognised. These risks were analysed for the UK's energy system, considered as 19 fuel supply chains (each with six stages), and scored by likelihood and impact on the supply chain (accounting for resilience). A risk matrix was constructed recording the risks encountered at each stage for each fuel. For the UK, the three causes with the greatest total score were ‘lack of access to capital’, ‘changing policy or regulatory framework’ and ‘significant public concern’, all of which were amongst the eight causes of risk noted as most significant at an expert verification workshop. This methodology yields a credible and direct quantification of risk for a national energy system – an indicator of energy security. It does not require the assignment of weighting factors to various contributory characteristics, often arbitrarily chosen in other approaches. It is suggested that the seven most prevalent causes of risk, that occur for nearly all fuels and all stages, may be systemic in nature. The method offers sufficient flexibility to make it readily applicable to other nations, regions, or sites, and other types of supply chain.

Georgia and Energy Security

Energy security means the continuous availability of energy, inadequate amounts at a reasonable price. It means when local and imported resources at a reasonable price meet the country's growing demand for energy. Energy Security impact depends on Environmental challenges, liberalization, deregulation, and the liquidity and competitiveness of the market; besides, the most affecting role in energy security plays the government. Global tensions, as well as regional conflicts, are the most challenging for today’s world. Adequate attention to environmental challenges and diversification of sources can be the solution to Energy security. Georgia entered the Energy Community Treaty on 1 July 2017. Membership in the Energy Community has a wider political consequence for the country as the membership shows its pro-European orientation. It’s worth mentioning that Georgia is the first Contracting Party not to have a border with the EU internal market or with any other Energy Community Party. Besides, membership of the Energy community redefines also the energy security questions. Georgia made an important improvement in the energy sector by replacing the energy market framework with the Third Energy Package. Georgian Energy law and policy mainly depend on better energy partnerships between the European Union and Georgia.

The attitude of the local community towards investments in lignite before transitioning to the post-lignite era: The case of Western Macedonia, Greece

In Greece, lignite has played a key role in energy security and has delivered notable social benefits such as local employment. Since mining projects affect profoundly the life of residents living in the vicinity of these projects, the understanding of residents' attitudes to lignite mining assumes a great importance as it can guide the design of policies. Hence, this study investigates the attitudes towards new investments in lignite mining among residents living near Greece's largest lignite center which is located in Western Macedonia. Results showed that a considerable share of residents desired new lignite projects and categorical regression analysis revealed that men desired new lignite plants more than women while, in terms of occupation, workers, undergraduate students, unemployed and private employees desired new lignite investments more than public employees and farmers. In addition, this study segmented survey respondents into three attitude groups (positive, neutral and negative) based on their desire for new lignite plants in their vicinity to indicate how the views of each attitude group on various topics related to resource extraction differentiate. As lignite phase-out is approaching in Greece, the findings of the present study may be particularly useful to policymakers in order to design a more socially acceptable decommissioning plan.

The role of energy security in the element base of the industrial region innovative development

The article examines the peculiarities of the relationship between energy security and innovation processes in the industrial region. Systemized approaches to the methodology for calculating the level of financial security have been consolidated. It is concluded that it is appropriate to use an indicative method of energy security analysis as a classic epistemological variant of the study of the energy security phenomenon. As a result of the assessment of the energy security level of the Kemerovo (Kuzbass) region it is concluded that all indicators of energy security except a certain degree of depreciation of the fixed assets of the fuel and energy complex enterprises have acceptable pre-crisis values. According to the share of own sources in the balance of electricity, the disposable capacity of power plants and the capacity of the largest power plant in Kuzbass region is in the pre-crisis zone, which determines its energy independence. It is noted that the share of coal as the dominant fuel resource in the structure of fuel consumption is at the pre-crisis level. The energy supply is emphasized to cover not only the issues of production, supply of energy resources and availability of energy sources, but also the aspects of the ecology and energy resources accounting. This determines the necessity to adjust the methodology for determining the energy security. It is proposed to supplement the methodology of assessing the level of energy security with indicators that take into account the diversification of sources of electricity generation both as a main resource and the possibility of commercial accounting of electricity consumption. The statement about the impact of the innovation level of energy on the level of region energy security and the pace of innovation process is justified.

Teorijski dometi izučavanja energetske bezbednosti kao globalnog izazova u međunarodnim odnosima

From the first discoveries of fossil fuels in the late nineteenth century to the present, the importance of energy resources has been gaining global proportions, not only in economic, political and social terms, but has become an indispensable aspect of national and international security. Energy has become an important factor in international cooperation (gas pipelines, oil pipelines), but also of open and covert conflicts and tensions (oil shocks, gas crises, economic sanctions). The work analyzes the development of theoretical directions for post-Second World War security studies and its weaknesses in understanding the importance and role of energy security in complex international relations. The aim of the work is to analyze and explain energy resources as an important factor of national and international security and its interdependence and complexity of economic, military, political, social and ecological phenomena with the aid of sector theory and global sociological approach.

A Downdraft Fixed-Bed Biomass Gasification System with Integrated Products of Electricity, Heat, and Biochar: The Key Features and Initial Commercial Performance

Biomass, as a renewable and clean energy resource, plays a vital role in energy security and greenhouse gas reduction across the world. This paper reports on our newly established technology: a downdraft fixed-bed biomass gasification system using nut shells (mainly apricot kernel shells) for electricity generation, heating and partially activated carbon production at the same time. Particularly, the key features of the gasification reactor will be presented in detail. In the commercial plant (3 MW scale) located in Hebei province, China, the typical energy conversion from apricot kernel shell gasification is as follows: 47% syngas, 44% char (partially activated carbon), 5% hot water, and 4% energy loss. The main gasification temperature is 600–800 °C, while the activation zone is 850–900 °C. The commercial system has currently been in operation for 4 years. Considering the partially activated carbon as a stable carbon carrier, the whole system features negative CO2 emissions.

Contextualizing hazard mitigation policy for electricity grids in the Sudan Sahel Region of Nigeria

Electricity grid resilience in the face of unending hazards plays a crucial role in energy security of a nation. Based on hazard impact variability across different regions of Nigeria, formulating and implementing a contextualized environmental hazard mitigation policy to reduce grid vulnerability to the multiple effects of hazards and disasters is a strategic imperative that can result to longevity of grid networks, with increased probability of critical success factors such as safety, reliability of electricity supply and electricity access in the Sudan Sahel region of Nigeria. Policies outlined in the Nigeria's National Disaster Management Framework (NDMF) and the scope of its National Disaster Response Plan (NDRP) takes no cognizance of the peculiar environmental hazards and disasters that impinges on sustainability of electricity grid infrastructures, and the mitigation strategies to reduce their risks, with reference to the Sudan Sahel region. This paper provides insight on the Sahelian hazards, overview shortcomings of the NDMF and NDRP, and advocates for the contextualization of hazard mitigation policy for electricity grids in the Sudan Sahel based on international best practices and findings of field surveys of the Zamfara Sahel.

Sustainable operation-oriented investment risk evaluation and optimization for renewable energy project: a case study of wind power in China

Renewable energy is playing an increasingly important role in energy security and environmental protection. As China has a huge demand for renewable energy and also has abundant wind resources, it is vital that government, investors and operators work together to ensure the sustainable development of the wind energy industry. Even though China is already a leader in wind power generation with the largest installed wind power capacity in the world, it has continued to build new wind power facilities. However, due to industrial immaturity and the need for significant investment, wind power investors and operators are faced with uncertainty about the attendant risks. To achieve risk mitigation and sustainability, this paper proposes an investment risk evaluation and optimization process for Chinese wind power projects. The Monte Carlo method is first used to evaluate the investment risks, after which a multi-objective programming model is built for the optimization. A specific case in western China is examined to demonstrate the proposed methodology, with the evaluation results indicating that the project has high investment risk. Based on the case study, the key risk factors are identified and optimization suggestions given for China’s wind power projects. The proposed methodology and findings contribute to research on the planning, investment and sustainable operation of renewable energy power generation projects in other areas in China.

Energy security and potential supply disruption: A case study in Japan

This paper provides new quantitative perspectives on energy security. We conduct an analysis in the event of energy resource supply disruption in exporting countries for Japan. The study showed that oil stockpiling by the government and firms plays an important role in energy security; the analysis shows that oil supply disruption does not cause latent demand of oil products — except naphtha — after the supply disruption. However, we found that the supply interruption of town gas caused by liquefied natural gas supply disruption is a possible weak point in Japan's energy security. This would mainly impact a variety of non-energy intensive sectors such as the customer sector. We also show that the energy security of the supply is degraded by the unplanned outage of nuclear power stations, as seen from the disaster at the Fukushima Daiichi Nuclear Power Station. Nuclear power generation and renewable energy power generation can mitigate the impact of energy resource supply interruption in the power generation sector.

Microalgae biorefineries: The Brazilian scenario in perspective

Biorefineries have the potential to meet a significant part of the growing demand for energy, fuels, chemicals and materials worldwide. Indeed, the bio-based industry is expected to play a major role in energy security and climate change mitigation during the 21th century. Despite this, there are challenges related to resource consumption, processing optimization and waste minimization that still need to be overcome. In this context, microalgae appear as a promising non-edible feedstock with advantages over traditional land crops, such as high productivity, continuous harvesting throughout the year and minimal problems regarding land use. Importantly, both cultivation and microalgae processing can take place at the same site, which increases the possibilities for process integration and a reduction in logistic costs at biorefinery facilities. This review describes the actual scenario for microalgae biorefineries integration to the biofuels and petrochemical industries in Brazil, while highlighting the major challenges and recent advances in microalgae large-scale production.

The Role of Energy Security in China's Foreign Policy: A Maritime Perspective

Energy, particularly oil and gas, has become a strategic component of China's foreign and security policy in recent times. Beijing's search for resources for its economic success has created a notion of “scramble for energy” that portrays China's increasing activity in the energy sector worldwide through investment and equity stake considered as a political strategy by the Chinese elites. In this energy hunt foreign policy option, China faces increasing security problems as its energy passes through the Malacca Strait and also the Indian Ocean region. As a result China pays significant attention to secure the sea-lanes of communication and for that Beijing applies a combination of diplomatic and military mechanisms in its overall foreign policy arena. In this scenario, its energy security could lead to some kind friction with other countries of the Indian Ocean littoral area, including India. In this regard this work attempts to analyse different aspects of China's energy security policy and its implication for India.
