An analysis is conducted to assess the stability of energy systems so to implement cutting-edge energy production models at the national level, with a focus on a contemporary approach to energy modeling. Considering the energy transition and the existing constraints within the energy industry, the model assesses the feasibility of the practical advancement of renewable energy sources. The bottom-up energy model was used to determine how the components of energy development sustainability can be applied until the year 2050. To perform comparison testing with the reference state scenario, the LEAP energy model was used. This instrument was selected because of its ability to provide flexible and advanced options for selecting suitable parameters for energy transformation prediction. A progressive reduction in environmental pollution can be achieved by the deployment of current methods of energy generation by transformation until the year 2050 in Serbia, as indicated by the findings. The research highlights the significance of utilizing green energy sources for the continuing development of energy and the gradual reduction in environmental pollution through value co-creation.

Ultrafast laser technology has moved from ultrafast to ultra-strong due to the development of chirped pulse amplification technology. Ultrafast laser technology, such as femtosecond lasers and picosecond lasers, has quickly become a flexible tool for processing brittle and hard materials and complex micro-components, which are widely used in and developed for medical, aerospace, semiconductor applications and so on. However, the mechanisms of the interaction between an ultrafast laser and brittle and hard materials are still unclear. Meanwhile, the ultrafast laser processing of these materials is still a challenge. Additionally, highly efficient and high-precision manufacturing using ultrafast lasers needs to be developed. This review is focused on the common challenges and current status of the ultrafast laser processing of brittle and hard materials, such as nickel-based superalloys, thermal barrier ceramics, diamond, silicon dioxide, and silicon carbide composites. Firstly, different materials are distinguished according to their bandgap width, thermal conductivity and other characteristics in order to reveal the absorption mechanism of the laser energy during the ultrafast laser processing of brittle and hard materials. Secondly, the mechanism of laser energy transfer and transformation is investigated by analyzing the interaction between the photons and the electrons and ions in laser-induced plasma, as well as the interaction with the continuum of the materials. Thirdly, the relationship between key parameters and ultrafast laser processing quality is discussed. Finally, the methods for achieving highly efficient and high-precision manufacturing of complex three-dimensional micro-components are explored in detail. [ABSTRACT FROM AUTHOR]

This paper uses a bottom-up national energy technology model to study the optimization of China's energy transformation pathway. The model clarifies specific action plans for China's energy transformation pathway from 2020 to 2060, total carbon emissions, industry emission reduction responsibilities, and other dimensions. The results show that: (1) The proportion of renewable energy consumption in China's entire energy system from 2020 to 2060 will gradually exceed that of fossil energy under ideal circumstances, and the energy system will transition from traditional fossil energy to renewable energy. Meanwhile, the proportion of low-carbon energy sources, such as renewable energy, in primary energy demand will jump from 15.9% in 2020 to over 80% by 2060. (2) China's CO2 emissions will be approximately 3 billion tons, 2 billion tons, and 1 billion tons under three different socio-economic development scenarios of low, medium, and high speed in 2060. At that time, China will still need to absorb CO2 through carbon sinks in forests, oceans, and wetlands. (3) The electricity industry has the highest CO2 emissions compared to other industries. The electricity industry must bear significant responsibility for carbon reduction in future energy transformation and economic development. [ABSTRACT FROM AUTHOR]

The high consumption of fossil fuels and concomitant contamination of the environment have promoted the search for new, low‐cost, and cleaner energy sources to satisfy the current energy demand around the world, decreasing the levels of greenhouse gas emissions to the atmosphere. One of the promising strategies to facilitate the generation of renewable energy involves solar‐driven chemical reactions, by using photocatalysts with improved sunlight absorption and carrier transfer abilities. Lead‐free halide perovskites (LFHPs) are good candidates, showing mesmerizing optical features, modulable band structure, oxidizing/reducing capability, and less toxicity compared to their Pb‐analogous. However, the literature reporting the photo(electro)chemical (PEC) properties of the LFHPs‐based materials for solar energy production is scarce. This review describes the current state‐of‐the‐art exhibiting the influence of the dimensionality, chemical composition and the formation of heterojunctions based on LFHPs on their photo(electro)activity for conducting solar‐driven hydrogen evolution, carbon dioxide (CO2) reduction, and the degradation of recalcitrant pollutants to obtain added‐value chemicals. In this way, it is also included the main challenges to be faced. Furthermore, we address some potential LFHPs to be explored in PEC systems, opening up the gamut of possibilities to consolidate the solar‐to‐chemical transformation as an innovative alternative to favor environmentally friendly energy production.

The dilemma of choosing between conventional energy and renewable energy sources is a topic of discussion in various economic and social sectors. This problem is not only a matter of the country's energy security but is also an important element of sustainable development that affects the functioning of future generations. The analysis of this process must cover all aspects of operation, with particular emphasis on tourism, including ski resorts. The aim of the work is to assess the current state of ski infrastructure in terms of the possibility of using green energy to power these types of devices, with an indication of the profitability of implementing this project. This analysis will cover the types of renewable energy sources and how they are used in winter sports resorts around the world, whilst additionally focusing on the energy structure of Poland and the European Union, as well as on energy transformation plans in Poland. An important aspect of this analysis is to understand the barriers to the development of the unconventional energy sector and the ski resorts themselves. The impact of ski resorts on the natural environment was also examined. When analyzing the profitability of introducing green energy to power ski slopes, the costs of traditional energy sources in a Polish ski resort were analyzed. The benefits of introducing green energy were indicated by comparing SWOT analyses of the Polish coal sector with renewable energy sources. In the economic context, the profitability of the proposed renewable energy installation was presented, using the NPV, IRR and payback period methods. The analysis of the cost structure of traditional energy sources allowed for the identification of a potential investment in renewable energy technologies, showing the share of electricity costs in the structure of energy carriers used on the ski slope. As a result, the profitability of the installation project was indicated as photovoltaic with specific power and parameters. Although the presented considerations refer to the realities and legal regulations applicable in one of the selected European Union countries—Poland, a country where energy from photovoltaic panels is developing the fastest among all renewable energy sectors in Europe—these considerations can be used in practice to indicate further directions and development prospects for other regions of the world. At the same time, the content of the considerations creates the basis for further development of research on these processes in order to popularize Poland's energy policy. [ABSTRACT FROM AUTHOR]

With increasing local conflicts worldwide, studying the impact response of body armor is crucial for enhancing soldier survival rates. However, there is still insufficient understanding of the back bulge expansion patterns, the impact waves transmission features, and blunt injury assessing method of body armor. To investigate these problems deeply, the three-dimensional digital image correlation method and numerical models were employed to reveal the ballistic response mechanism of ceramic/ultra-high-molecular-weight polyethylene (UHMWPE) composite body armor impacted by 7.62 mm rifle bullet. This study built theoretical function for the bulge expansion, revealed the wave transmission mechanism and fractures in both materials and their interaction. Firstly, the experiment revealed that the back-face bulge transverse expansion velocity exhibits a double exponential decrease. Secondly, the contour of back-face bulges consistently demonstrated excellent hyperbolic characteristics at various moments. Thirdly, the average Viscous Criterion (VC) and Blunt Criterion (BC) values were 5.37 and 0.95, corresponding to Abbreviated Injury Scale (AIS) values of 6 and 4. Fourthly, the simulation revealed that the ceramics transverse and radial cracks seems primarily induced by shear stress xy; ceramics conical cracks occurring at the boundaries of equivalent stress seems primarily induced by stress in x and y directions. Fifthly, numerical results revealed that the velocity of compression waves within the laminate increases over time in the impact direction and consistent with ceramic velocity impacted on the laminate. These findings lead to experimental and theoretical advances in the impact response mechanism of composite body armor and provide index for improving the protective performance.

Abstract The coordinated development of intelligence and greening is an intrinsic demand for high-quality economic and social development. Intelligentization and greening are the leading directions of sustainable development of the power industry. This paper directs of sustainable development of the power industry. This paper empirically analyzes the effect and mechanism of intelligence on the green environmental friendliness of electric power substations by using a panel fixed-effects model and instrumental variable regression, using substation engineering data from China southern power grid during 2013–2022. It is found that the level of intelligence significantly promotes the green performance of substation projects, and this conclusion still holds after a series of robustness tests. Intelligence can reduce material waste and pollutant emissions by improving the engineering environmental monitoring capability and the refinement of engineering resource control, thus improving the environmental friendliness of the project. The research in this paper helps to promote the integrated development of intelligent and green power engineering, to better achieve economic and green goals.

Over the past two decades, the Taiwan government promulgated some regulatory measures and promotional actions on energy efficiency promotion and renewable energy development. In March 2022, the "Taiwan's Pathway to Net-Zero Emissions in 2050" was announced to respond to the Paris Agreement. In order to achieve the goal, the Climate Change Response Act (CCRA) was passed on February 15, 2023, requiring the de-carbonization measures and adaptation strategies. The main aim of this paper was to analyze the changes in GHG emissions and renewable energy supply by using the updated data from the official statistics in connection with the trends of environmental and energy sustainability since 2000. The findings showed that total installed capacity of renewable power (especially in solar power and wind power) showed an amazing increase over the past decade, leading to the inclined GHG emissions and thus supporting the environmental and energy sustainability toward a low-carbon society. Furthermore, this paper summarized the development history and main differences concerning the carbon neutrality policy and legislation in Japan and South Korea. For achieving the staged targets of GHG emissions by 2030 and 2050, this paper finally addressed the technological approaches for achieving carbon neutrality by 2050 in Taiwan, focusing on the transformation of energy and industry, and the policy implications by all levels of government.

In light of China's rapid growth and increasing engagement in the global climate regime, the authoritarian regulatory model has attracted attention from researchers and policymakers alike. This paper examines the question of to what extent and in what way state authoritarianism leads to (un)successful environmental policy implementation in China, with particular attention to energy transformation. This study inter-connects macro and micro inquiries through a case study of nuclear energy policy in China. An examination of the extended policy cycle as a comprehensive process that brings a policy to fruition shows that authoritarian regulatory environmental policy intervenes in each stage, resulting in a particular path of the evolution of environmental policy in nuclearising energy transformation in China. Adding to commonly accepted tenets of authoritarian environmentalism in general, the explanations of Chinese distinctiveness in materialising environmental policy enhances the understanding of the merits and challenges of authoritarian mechanisms of environmental policy.

In this paper, we propose new Metropolis–Hastings and simulated annealing algorithms on a finite state space via modifying the energy landscape. The core idea of landscape modification rests on introducing a parameter c , such that the landscape is modified once the algorithm is above this threshold parameter to encourage exploration, while the original landscape is utilized when the algorithm is below the threshold for exploitation purposes. We illustrate the power and benefits of landscape modification by investigating its effect on the classical Curie–Weiss model with Glauber dynamics and external magnetic field in the subcritical regime. This leads to a landscape-modified mean-field equation, and with appropriate choice of c the free energy landscape can be transformed from a double-well into a single-well landscape, while the location of the global minimum is preserved on the modified landscape. Consequently, running algorithms on the modified landscape can improve the convergence to the ground state in the Curie–Weiss model. In the setting of simulated annealing, we demonstrate that landscape modification can yield improved or even subexponential mean tunnelling time between global minima in the low-temperature regime by appropriate choice of c , and we give a convergence guarantee using an improved logarithmic cooling schedule with reduced critical height. We also discuss connections between landscape modification and other acceleration techniques, such as Catoni's energy transformation algorithm, preconditioning, importance sampling, and quantum annealing. The technique developed in this paper is not limited to simulated annealing, but is broadly applicable to any difference-based discrete optimization algorithm by a change of landscape.

Ensuring military and police personnel protection is vital for urban security. However, the impact response mechanism of the UHMWPE laminate used in ballistic helmets and vests remains unclear, making it hard to effectively protect the head, chest, and abdomen. This study utilized 3D-DIC technology to analyze UHMWPE laminate's response to 9 mm lead-core pistol bullets traveling at 334.93 m/s. Damage mode and response characteristics were revealed, and an effective numerical calculation method was established that could reveal the energy conversion process. The bullet penetrated by 1.03 mm, causing noticeable fiber traction, resulting in cross-shaped failure due to fiber compression and aggregation. Bulge transitioned from circular to square, initially increasing rapidly, then slowing. Maximum in-plane shear strain occurred at ±45°, with values of 0.0904 and −0.0928. Model accuracy was confirmed by comparing strain distributions. The investigation focused on bullet-laminate interaction and energy conversion. Bullet's kinetic energy is converted into laminate's kinetic and internal energy, with the majority of erosion energy occurring in the first four equivalent sublaminates and the primary energy change in the system occurring at 75 μs in the fourth equivalent sublayer. The results show the damage mode and energy conversion of the laminate, providing theoretical support for understanding the impact response mechanism and improving the efficiency of protective energy absorption.

Nonlinear energy sink (NES) is a device used for structural vibration reduction, which can not only achieve targeted energy transfer, but also has many advantages such as wide working frequency band, high reliability and strong robustness. In a fractional-order differential system, the historical memory of fractional-order differential operators enables us to more accurately simulate and study physical phenomena in actual systems. With this in mind, the vibration suppression performance of the fractional-order damping system coupled with NES is considered. However, random vibrations are everywhere and systems are susceptible to random excitations. Therefore, this paper conducts a numerical and analytical investigation into the dynamic response mechanism of a fractional-order damping system excited by random excitation, which coupled with a NES. Firstly, The Fokker–Planck–Kolmogorov equation and stationary probability density function expression are derived by using stochastic averaging method. Secondly, The effectiveness of this approach is confirmed by the concurrence between the analytical solutions and the numerical solutions obtained through Monte Carlo simulation. Subsequently, the effects of system parameters and noise intensity on the stationary response of the system are discussed, as well as stochastic P-bifurcation caused by system parameters. Ultimately, the time histories of displacement and the energy transformation of the primary structure with changes in system parameters under the condition of coupled with NES and without NES are analyzed to verify that NES can achieve the desired goal of vibration reduction.

The structure and operating principle of a four-stroke internal combustion engine are usually demonstrated using the cut-away model of an internal combustion engine or its computer animation. However, by observing the operation of the engine mechanism, the understanding of the main essence, which consists of the transformation of thermal energy from the combustion of gasoline into the mechanical energy of the piston movement is lost. This work describes the demonstration of the ignition and combustion of the fuel mixture and the transformation of thermal energy generated by the combustion of gasoline into the mechanical energy of the piston. A paper rocket is used instead of a piston for the spectacle of the experiment. This demonstration does not leave anyone from the audience indifferent. The dependence of rocket flight height on the mass of burned gasoline was established. [ABSTRACT FROM AUTHOR]

The climate challenges posed by the European Union are particularly difficult for emerging and developing economies. This causes reluctance to undertake them and even denial of their validity. For this reason, this article seeks to answer the question of whether it is possible to carry out an effective transformation of energy resources in the developing economies of the Visegrad Group. Analyses in this area are conducted in a long-term, 58-year research perspective (1965–2022) and concern the Czech Republic, Hungary, Poland, and Slovakia. The effectiveness of the examined transformation is assessed in two dimensions as follows: (1) resource and (2) emission, which are then synthesized using a multi-criteria analysis. This research shows that an effective resource transformation aimed at a zero-emission economy is possible even in emerging and developing economies, although it undoubtedly requires time and consistency in the implementation of the once-chosen energy policy. Hungary—a leader in assessed climate effectiveness—has systematically decarbonized while reducing the use of total non-renewable resources. The Hungarian resource transition strategy assumed the use of nuclear energy and an increase in the share of renewable resources. The result of these activities is a quite diversified energy mix, which is greater resource self-sufficiency and low carbon dioxide emissions. The Czech Republic also achieved a similar strategy and results. Poland and Slovakia coped much worse with the climate challenge: although they gave up coal, they replaced it largely with other non-renewable resources. It is worth emphasizing that Poland has managed to significantly increase the use of renewable resources, and nuclear energy and hydropower have also appeared in the Slovak mix. Nevertheless, this did not allow for achieving good climatic results. [ABSTRACT FROM AUTHOR]

Accelerating the transformation of the rural energy structure is an indispensable part of energy transformation in developing countries. In this novel study, the transformation effect of China's rural energy structure from 2001 to 2020 was evaluated. Further, this paper also identified the decoupling state between the rural energy structure transition and carbon emissions, and decomposed the spatial–temporal effects of rural carbon decoupling through efficiency measures. According to the survey, the dual substitution index of the rural energy structure in China increased from 0.466 to 1.828, and showed a decreasing trend in spatial distribution from the east to the central and western regions. Economic development and climate characteristics have become important influencing factors for the dual substitution of the rural energy structure. The decoupling relationship between the dual substitution of the rural energy structure and carbon emissions was mainly characterized in the strong decoupling, expansion negative decoupling, and strong negative decoupling states. Regional imbalances have deepened as the efficiency of rural energy carbon decoupling has gradually increased. The annual average efficiency of rural energy carbon decoupling in a dynamic perspective has increased by 10.579%, and the dual substitution of the energy structure has a significant driving effect on rural carbon reduction.

Manifestations of energy transformation are visible throughout the developed world. As the threat to the survival of humanity arises, the countries of the world are starting to take faster and more specific actions to transform the energy sector. One of the energy transformation strategies is the decentralized development of the energy system in the regions. This concept is especially relevant at this time, when centralized sources of energy production and supply are becoming the target of physical and cyber attacks. The purpose of this article is to form theoretical assumptions for the smooth implementation of the decentralization of the energy system. This article aims to remove obstacles to short-term energy transformation. The novelty of this article is related to emphasizing the role of biomass cogeneration in achieving energy system efficiency and greening. Mathematical modeling based on RSM is used in the article. The established factors of the market structure revealed that the efficiency of energy production is based on the use of cogeneration and the markets for raw materials and energy can be attributed to different types. The results of this study showed that the optimal combination of biomass cogeneration can ensure competitive energy production. This article is relevant because it offers transitional solutions until adequate hydrogen utilization and energy storage solutions are developed. [ABSTRACT FROM AUTHOR]

This paper provides a legal analysis of the direct line in the legislation of the European Union. The direct line, serving as a legal instrument to implement off-grid solutions, plays a crucial role in amplifying competition within the energy market. Compared to other instruments introduced by the First Liberalization Package in 1992, the direct line is not a subject commonly brought about by legal literature. The core part of legal analyses is divided into two parts, which focus on different approaches of direct line, i.e., European Union and selected Member States (Estonia, Latvia, Lithuania, and Poland). The motives of the Union in establishing the direct line instrument was to support opening the energy market to increase energy generating units. During the transposition of the direct line into national laws, analysed countries have directed the usage of this mechanism to promote renewable energy sources. The presented case studies create a rare pattern of how the Member States form their own interpretations and hence use the Union law in practice, which differs from the direction established in the Union forum. The research focused on legal dogmatic examining of regulations at both European and national levels, with a particular emphasis on the definition part while figuring a crucial role in shaping the direct line concept. The paper also presents other convoluted legal schemes, such as the permit issuance process for direct line construction. The conclusions assess the modifications in the European Union regime, but also their impact on electricity prices and green investments. [ABSTRACT FROM AUTHOR]

The abundant natural resources and rapidly falling prices to generate and store renewable energy create a remarkable opportunity for a new group of manufacturing industries to emerge. These technology pathways use abundant or waste resources to produce green chemicals and fuels like green hydrogen (H2), green ammonia (NH3), and green synthetic hydrocarbons (HCs). Integrating chemical processes and renewable energy can complete the carbon loop and bring substantial decarbonization along with economic opportunities around the globe. An evidence‐based and industry‐focused critical review of technologies to produce green chemicals and fuels from renewable energy is presented. It also discusses the market size and applications for these emerging industries and presents their development status, benefits, and challenges to commercialization. Green hydrogen production from renewable energy turns out to be the initial and key stage for all these technological advancements and is indispensable for their techno‐economic viability. Other environmentally friendly feedstocks, such as nitrogen (from the air) and wastes such as CO2 (from industrial flue gas), can produce green chemicals. Besides environmental benefits, several other benefits of producing green chemicals from renewable energy are identified. These include but are not limited to (i) accelerating the economy for renewable energy and hydrogen generation, (ii) savings in energy, costs, and natural resources, and (iii) creating millions of jobs. A perspective on opportunities to develop the green chemical industry and assist academia, industry, and policymakers is provided. [ABSTRACT FROM AUTHOR]

Background: Bioenergetic remodeling of core energy metabolism is essential to the initiation, survival, and progression of cancer cells through exergonic supply of adenosine triphosphate (ATP) and metabolic intermediates, as well as control of redox homeostasis. Mitochondria are evolutionarily conserved organelles that mediate cell survival by conferring energetic plasticity and adaptive potential. Mitochondrial ATP synthesis is coupled to the oxidation of a variety of substrates generated through diverse metabolic pathways. As such, inhibition of the mitochondrial bioenergetic system by restricting metabolite availability, direct inhibition of the respiratory Complexes, altering organelle structure, or coupling efficiency may restrict carcinogenic potential and cancer progression. Scope of Review: Here, we review the role of bioenergetics as the principal conductor of energetic functions and carcinogenesis while highlighting the therapeutic potential of targeting mitochondrial functions. Major Conclusions: Mitochondrial bioenergetics significantly contribute to cancer initiation and survival. As a result, therapies designed to limit oxidative efficiency may reduce tumor burden and enhance the efficacy of currently available antineoplastic agents.

The captivating surge of energy transitions in the major industrialized nations has elevated the global demand for critical minerals. The demand pattern has enabled mineral-abundant emerging economies like Indonesia to enter the international market by exporting mineral goods. Accordingly, we investigate the Indonesian mineral export supply's response to the renewable energy production of the 18 clean energy-generating countries, considering crude oil and mineral prices, exchange rates, and economic growth of the resource and importer countries from 1990 to 2020. In doing so, we apply the Poisson Pseudo-maximum Likelihood (PPML) approach to measuring the panel gravity model for mineral exports in Indonesia. As a result, we observe a significant response of Indonesia's mineral export supply to the renewable energy generation of the 18 mineral importing countries. Besides, mineral and crude oil prices are insignificant, whereas the importer countries' exchange rates and income growth positively influence Indonesia's mineral export growth. However, Indonesia's income factor negatively affects its mineral export supply. Finally, we validate our results using an alternative estimator, the Driscoll-Kraay robust standard error estimation technique. Therefore, our findings suggest implementing Indonesia's existing mineral policy to produce finished mineral goods to materialize the worldwide vision of energy transitions toward a crossroad of net-zero emissions by the middle of the current century.

To reach the climate goals set by national and international institutions, a vast transition of the legacy power system is unavoidable. The necessary integration of distributed, renewable generation devices, which are often interfaced with power electronic converters, has a non-negligible influence on the characteristics of the power grid. This is particularly visible during abnormal grid conditions such as faults. For rotating machines, the fast-timescale reaction to these events is mainly determined by physical properties. However, power electronic devices lack this strong coupling and their behavior is generated by the control and automation system, making them a major field of interest during this transition. The present paper provides a survey of real-world incidents, as for example blackouts or oscillatory incidents, that are discussed with respect to the implications for future converter dominated power grids. For typical cascading outages it is shown, where the increasing penetration of distributed, renewable generation and smart grid technologies can be leveraged to increase the system resilience, e.g. by providing grid services through adequate control design or by enabling microgrid concepts. Further, real-world examples of newly emerging challenges driven by power electronic devices are presented. The mechanisms of control system interactions with the neighboring grid and its inherent complex dependency on various factors is illustrated. Lastly, resulting structural developments such as the changed resonance properties of low voltage grids and the increase of harmonic emissions are exemplified.

The challenges of climate change encourage immediate solutions by creating the conditions for energy transformation. This process is significantly related to capital investments and the conversion of existing assets to clean energy sources. Due to the need to save resources, workplaces, and public favor, specific studies involving different data groups are necessary. This article presents key data sources for analyzing the impact of energy transformation on Lithuanian regions—governance, potential, and existing power indicators. The economic, social, and governance data combined in the article will allow us to determine the perspectives of sustainable energy transformation in the regions. The article showed that in certain regions there may be major, complex problems that hinder the breakthrough of the energy system. Cluster analysis and a generic system diagram were used for the research, which showed that municipalities have a wide potential for energy transformation. The research emphasizes the governance component as a key success factor. After reorganizing the management of municipal enterprises, further actions can be initiated, since emerging competences allow progress to be made efficiently and with less time spent. The asset analysis methodology presented in the article allows for the identification of the main groups of assets that can be converted in the short term for the purpose of energy transformation, according to sustainable development principles. These decisions provide an opportunity for decision-makers to consistently implement energy transformation decisions. [ABSTRACT FROM AUTHOR]

Exploring the formation mechanism of farmers' behavioral intention to adopt electricity to replace coal (INT-CE) is important for adjusting energy policies in the context of passive energy transition. Based on the integrated framework of Theory of Planned Behavior (TPB) and Normative Activation Model (NAM), taking farmers in Yulin City, Shaanxi Province as the research sample, the formation mechanism of INT-CE is empirically analyzed using partial least squares structural equation modeling (PLS-SEM). INT-CE was influenced by both self-interested and altruistic motives, with self-interested motives having a greater impact. The results show that: (1) Subjective attitudes and perceived behavior control have significant positive effects on low-income farmers' transformation intention, the influence coefficients are 0.170 and 0.331, respectively. (2) Perceived behavior control has a significant positive impact on the transition intention of middle - income farmers, the coefficient is 0.155. (3) Subjective norms have significant positive impacts on the energy transition intention of high-in- come farmers, the coefficient is 0.261. Attitude has the greatest influence on INT-CE. The effect of past habits on INT-CE was not significant, but was controlled by attitudes and perceptual behaviors. Outcome awareness and responsibility attribution indirectly enhance INT-CE through personal norms. The government should consider farmers' self-interest and altruistic motives when motivating INT-CE. On the one hand, positive concepts of energy conservation should be fostered and farmers' knowledge of energy conservation should be enhanced. On the other hand, the education of farmers should be strengthened to make them realize the ecological damage caused by non-clean energy. At the same time, the influence of relevant groups on INT-CE should be further emphasized to play the role of demonstration and leadership, to enhance farmers' environmental awareness and to cultivate a sense of social responsibility to protect the ecological environment.

The formulation of long-term step-by-step emission reduction plan is an important step for effective scientific emission reduction. This paper takes Shanghai as the research object, constructs PSO-LSTM model on the basis of STIRPAT model, and further constructs three dynamic policy scenarios combined with China's actual situation and makes short-, medium-, and long-term multivariate predictions for them. The study finds that only the improvement of energy consumption structure has a promotion effect on carbon emission reduction, and urbanization, industrial structure, technology level, population, and economic level all have an increasing effect, and secondly, the carbon emission reduction path of Shanghai basically achieves the core objective of steady decrease under the three scenarios. Secondly, under the three scenarios, Shanghai's carbon emission reduction path basically achieves the core objective of steady decline, but the decline in the GU scenario is more significant. It is recommended that Shanghai further adjusts its industrial structure, optimizes its energy consumption structure, promotes technological innovation and progress, and promotes the development of the circular economy model.

After joining the globalization initiative, countries from the Association of Southeast Asian Nations (ASEAN) have experienced an exponential growth in carbon emissions. The high carbon lock-in of the energy consumption structure and lagged energy infrastructure construction have led to high carbon emissions, which has put great pressure on ASEAN countries to reduce their carbon emissions. To achieve the goal of carbon neutrality by the middle of this century, ASEAN countries have successively formulated strategic guidelines for energy transformation and green development, focusing on the structural transformation of energy development and utilization, a coal decommissioning plan, grid interconnection, the electrification of urban transportation patterns, energy conservation, consumption reduction, and international technological cooperation. ASEAN countries still face many challenges in achieving their carbon neutrality targets, including unstable policies, poor environmental awareness among residents, poor guarantee for energy transformation, disconnection between technology and capital, and difficulties in regional coordination. These are reflected in the obvious carbon lock-in effect and the strong dependence on carbon in traditional industries. ASEAN countries are seeking a balance of interests in the Sino–US infrastructure game. In this context, China, as an advocate of South–South cooperation, is committed to expanding the cooperation with ASEAN countries on carbon neutrality in the following aspects: the development and utilization of renewable energy resources, formulation of a progressive grid interconnection plan, establishment of the green financial system, and research and development of green technologies. The purpose is to help ASEAN countries achieve their goals of carbon neutrality. [ABSTRACT FROM AUTHOR]

When solving open-region electromagnetic scattering problems using the standard finite element method, the infinite region exterior to the scatterer must be truncated with an artificial outer boundary. In the interior or finite part of the domain, finite elements can be used, but a boundary condition must be introduced at this artificial boundary to obtain a unique finite element solution. One class of boundary conditions designed for this purpose is called absorbing boundary conditions (ABCs). Several ABCs have been reported in the literature. These can be broadly classified into two categories: local and non-local. In this paper, we present new closed-form expressions for Nth-order local ABCs, equivalent to the well-known sequences of the Bayliss, Gunzburger, and Turkel boundary operators. To the best of our knowledge, these expressions have not yet been reported in the literature. Two- and three-dimensional problems are considered in this study. We also discuss the problem of incorporating custom ABCs into commercial finite element method programs, which are usually closed-source software packages. Two 2D electromagnetic scattering and radiation problems with known analytical solutions are analyzed. [ABSTRACT FROM AUTHOR]

China’s energy transformation is at a critical stage, and virtual power plants are also in full swing. It is of great theoretical value and practical significance to identify whether virtual power plants can promote energy transformation. First, the concept of virtual power plant and energy transformation is defined, and the theoretical logic of interaction between virtual power plant and energy transformation is expounded. Then, the attribute model of the energy transition index is constructed from the attributes of energy system performance and energy transition maturity, and a double difference model is established. Finally, nine pilot provinces are taken as examples for empirical testing, and the results show that the implementation of virtual power plant pilot can promote energy transformation, but there are differences among provinces. The resource endowment and the degree of marketization and openness will have a differentiated effect on the promotion of energy transformation by virtual power plants.

The article presents a proposal for a comprehensive methodology for the design of the process of local production of alternative energy fuel. The goal of the methodology is to ensure a local source of renewable fuel (biomass) for the needs of covering the supply of thermal energy to citizens in rural areas. In the first part, the methodology deals with the issue of sustainable cultivation of energy crops, namely short rotation coppice and its appropriate placement on soil blocks which are threatened by erosion or degraded by intensive agriculture. Subsequently, the local energy community independently produces alternative pellet biofuel, from the initial cultivation of young woody plants to the final production of ecological wood-based fuel with a calorific value of 16 MJ/ kg. The proposed innovative method of heat production leads to environmental benefits, energy savings, reduced payments for energy supply, and overall modernization of the technologies used.

Objectives The aim of the work is to analyze the extremely dynamic changes in the perception of the information society. On the one hand, we are dealing with enormous technical and technological progress, which is caused by automation and robotization in the context of the 4th industrial revolution (Industry 4.0), and on the other hand, the rapid development of interpersonal and corporate communication in the era of a knowledge-based society, using various sources of information from the connectivism. Material and methods The applied method of in-depth analysis of information sources, through a comparative analysis of publications by Polish and foreign authors, as well as an analysis of speeches and publications at the Citizens' Congress in 2022. The published materials and legal acts of the European Commission were used as an auxiliary. Results The comparative analysis of various sources of information has shown that the development of the information society takes place on many levels, with the directions of this dynamic development mainly relating to the use of new applications of ICT technologies, as well as a significant development of the use of solutions in the field of virtual and augmented reality and artificial intelligence and the Internet of Things. Conclusions Many authors have already tried to answer the question: where are we going by implementing the ideas of a knowledge-based society. The reports of the World Bank and IBM indicate that as a result of rapid economic changes, the following will most likely occur: the development of various forms of verbal and visual communication between employees, workers and machines (humanoid and industrial robots - automatons), as well as the replacement of existing forms of interpersonal communication by communication with virtual employee avatars.
