Managing Electricity Costs in Industrial Mining and Cryptocurrency Data Centers
Authors: Dzyuba Anatolyy , Solovyeva Irina , Konopelko Dmitry
Published: July 2023

2022 has seen a significant decline in global cryptocurrency ratings, especially bitcoin. As it is known, one of the key components of the cryptocurrency’s cost is the amount of electrical energy spent by the computing equipment of the mining data centers. In the context of declining bitcoin rates, the management of the data centers’ energy costs becomes critical for maintaining the profitability and investment return of the mining projects. Russia is among the top-3 leading producers of cryptocurrencies, providing 11% of the global primary bitcoin transactions. In this regard, the management of the data centers’ costs related to the purchase of electricity in the Russian wholesale and retail electricity (capacity) markets presents a high scientific and practical importance. This article analyzes the pricing mechanisms for the purchase of electricity in Russia’s wholesale and retail electricity (capacity) markets on an industrial scale given the specifics of the hourly demand-based pricing. This paper suggests a new metrics system, including a capacity demand management coefficient and a transmission cost management coefficient, which allow setting specific price parameters for the different components of the electricity price based on demand analytics. Simulation of different parameters of the energy cost management in mining data centers demonstrated that the ultimate electricity price can, on average, be reduced by 70% of the initial level across all regions of the Siberian Federal District of Russia. The suggested energy cost management model takes into account both internal and external factors of industrial data centers as well as monitoring of their operations along with the price factors of the wholesale and retail electricity markets. This material may be useful to specialists in the field of management of mining data centers who are involved in the operation and/or design of such facilities across various regions of Russia.

Published: July 2023

In this study, the nexus between the generated oil revenue in Nigeria from 1981 to 2021 and its possible influences on the relative growth of the economy on a sustainable basis has been investigated. Utilizing the Johansen Co-Integration test, Granger Causality Technique as well as the Error Corrections Mechanism (ECM) to analyze the sourced data from both the World Development Indicators and the Nigeria Centra Bank. The findings depict the occurrence of a long-run connection amongst the variables of the study as both the eigenvalue test and trace test depict two and three cointegrating equations respectively at a 5% level of significance. 34.8% of short-run errors are rectified annually, according to the error correction mechanism. As a result, the coefficient reflects the rate of adjustment at which the RGDP's short and long runs are tied together. Further findings reveal that economic growth (RGDP) granger caused oil revenue (OREV) and that the generated oil revenue in Nigeria (OREV) granger caused economic growth (RGDP) during the study period. This suggests that the generated oil revenue in Nigeria (OREV) and economic growth (RGDP) relationship is causally bidirectional. This study, therefore, recommends the creation and efficient implementation of policies that facilitate prudent identification, collection and utilization of the generated oil income and adequate deployment to critical underdeveloped and developing sectors of the economy.

Authors: Aslanova Afaq , Mammadova Simuzar
Published: July 2023

Petroleum and natural gas, which are among the most used energy sources in the world, have a significant impact on financial markets and macroeconomic indicators as they are used as raw materials in many fields. For this reason, Russia, Turkey, Brazil, and India, as energy importers and developing countries, may be affected positively or negatively by changes in energy prices. The main purpose of this research is to investigate the relationship between the exchange rates of Brent oil, crude oil (WTI), natural gas, the US dollar index, and the Russian ruble. In the study, weekly data between February 6, 2022, and December 25, 2022 were examined. A vector autoregressive model (VAR) was used to examine the relationship between the variables included in the analysis, and the direction of the relationship between the variables was determined by the Granger causality test. According to the results of the VAR model, the WTI price has a significant effect on the USD/RUB rate, but the USD/RUB rate does not have a significant effect on the Brent and crude oil prices. On the other hand, the results of the Granger causality test confirm the findings of the VAR analysis.

Authors: Daly Saida , Abdouli Mohamed
Published: July 2023

In fact, this study endeavors to explore the relationship between CO2 emissions, trade, and economic growth using the simultaneous equation for Saudi Arabia over the period 1990–2017, using the VAR model and the impulse response functions to examine the relationship between these variables. Therefore, the obtained results showed that there is evidence of a bidirectional causality between CO2 emissions and economic growth. Moreover, the feedback hypothesis between trade openness and CO2 emissions is validated. Then, the retroaction hypothesis between economic growth and trade openness is identified.  Furthermore, our results indicate economic growth impede environmental quality, while our empirical results have established crucial relationships that have important policy implications. However, it is mandatory for policy makers to develop economic, environmental and outside policies to promote economic growth and trade and improve the environmental quality.

Published: July 2023

The potential for solar power is available in Indonesia because it is located on the equator, with good sunshine all year round. The Indonesian government is currently actively developing a solar power plant while still looking at the consequences of development, especially on the surrounding environment. It is necessary to pay attention so that it does not disturb the surrounding environment, which can also cause climate change. The city of Medan is one of the largest cities in Indonesia, which has direct exposure to sunlight which is quite promising for predicting solar power plants in the future. Solar energy generation in the last decade has continued to improve and develop in solar power predictions in a short period. Integration of solar power sources without accurate power predictions can hinder network operations and the use of renewable generation sources. To solve this problem, virtual power plant modeling can solve as a solution that manages to minimize the prediction error. This research studies methods that can efficiently generate significant daily Photovoltaic (PV) predictions at the locations studied using available data from the Meteorology, Climatology, and Geophysics Agency (MCGA). The approach of the two models based on RMSE (root mean square error) and MAE (Mean Absolute Error), can be virtual power plant modeling can solve it as a management solution to be minimal in its prediction error.

The approach of the two models based on RMSE (root mean square error) and MAE (Mean Absolute Error), can be taking into account the uncertainty of predictions that can provide additional information from virtual power plants. Verified prediction strategy performance against PV module power output and a set based on geographic meteorological station data have been used to simulate Virtual Power Plants (VPP). The power forecasting prediction refers to the LSTM (Long Short-Term Memory) network and gives an error close to that of other learning methods, based on the RMS characteristic of 4.19 W/m2 under lead time with different launch times. The application of the VPP model can reduce the global error by about 12.37% with the model RMSE, and shows great potential.

Authors: Muradzada Imangulu , Akbulev Nurkhodza
Published: July 2023

In the study, the short-term causality relationship between oil and natural gas prices, which are the main energy sources, and the XTRZM index was analysed with the Granger causality test. The DCC-GARCH model was used. Analyses were carried out over the monthly closing values between 02.01.1997 and 01.12.2022. According to the Granger causality test findings, the reason for both Brent oil and Crude Oil WTI in the XTRZM index is that Brent oil is the cause of Crude Oil WTI. It has been concluded that natural gas, Brent oil, and crude oil are not the causes of the XTRZM index and each other. Because Brent oil and crude oil are not included in the WTI XTRZM index, it has been determined that there is unidirectional Granger causality from the XTRZM index to Brent oil and crude oil WTI. According to the findings obtained from the DCC-GARCH model, there is a positive correlation between natural gas, Brent oil, crude oil, and the BIST tourism index.

Published: July 2023

This study examines the dynamic impact of financial development, trade openness, and economic growth on carbon dioxide (CO₂) emissions in Saudi Arabia. We applied the autoregressive distributed lag bound testing technique for the period of 1990–2019. The empirical results show a long-run cointegration relationship among the variables. The long-run estimation results, however, reveal that, economic growth, and trade openness have a positive and significant impact on carbon dioxide emissions, whereas all variables have a negative and significant impact on carbon dioxide emissions, in the short-run. The findings suggest that the government should emphasize programs and policies that reduce carbon dioxide emissions by opening the trade sector, considering the roles that openness plays in reducing environmental degradation in the country, which directly enhances environmental quality.

Authors: Gutiérrez Raúl De Jesús , Gutiérrez Lidia E. Carvajal , Salgado Oswaldo Garcia
Published: July 2023

This paper estimates a variety of CGARCH and FIGARCH models with normal distribution to capture salient features of Mexico’s Isthmus crude oil return series such as fat tails and volatility clustering as well as asymmetry and long memory; this to obtain independent and identically distributed standardized residuals series. Furthermore, extreme value theory is applied to model the tail behavior of the innovation distribution of the volatility models in estimating one-day-ahead VaR and Expected Shortfall (ES). In- and out-of-sample forecasting performance is evaluated by the unconditional coverage test of Kupiec and the Dynamic Quantile test of Engle and Manganelli. Backtesting results show strong and consistent evidence confirming that FIGARCH-EVT, ACGARCH1-EVT and CGARCH-EVT approaches yield the most accurate out-of-sample VaR and ES forecasts, for both short and long trading positions at quantiles ranging 95% to 99.9%. Findings provide useful tools for producers, consumers and portfolio investors who need sophisticated models for sound risk management and optimal hedging strategies to mitigate price risk exposure for the Isthmus crude oil.
Technical and Financial Assessment of Photovoltaic Solar Systems with Bifacial Technology Comparing Four Scenarios with Different Albedos with Respect to the Base Scenario with Monofacial Technology, in a Tropical Location in Colombia
Authors: Muñoz Yecid , De La Rosa Miguel , Acevedo Leidy Carolina , Velandia Wilmer
Published: July 2023

In photovoltaic system installations worldwide, the use of bifacial technology has begun to be more frequent due to the reduction of the cost gap associated with the manufacture of photovoltaic modules with bifacial technology compared to monofacial, encouraged by the technological maturation of bifacial modules. This research focuses on assessing the technical and financial viability of a photovoltaic solar system with bifacial technology, comparing 4 scenarios with different albedos (0.15, 0.2, 0.3 and 0.4) with respect to a base scenario that uses monofacial technology, the financial viability was evaluated according to three financial goodness criteria (NPV, IRR and Payback Time), where only in the scenario with albedo 0.4 were the costs associated with this land adaptation considered. The results of the research indicate that the most technically and financially viable scenario is the scenario with albedo 0.4, with an investment of $ 37,872 MCOP (3.71% more than the base scenario), an energy generated per year of 21,687 GWh/year (4.83% more than the base scenario), a net present value of $46,425 MCOP (8.42% more than the base scenario), an internal rate of return of 18.31% (1.78% more than the base scenario) and a payback time of 5.21 years (3.52% less than the base scenario).
Sustainability Analysis of Electricity Generation in Colombia through the Projection of Energy Efficiency Indicators
Authors: Valencia-Duque Melissa , Zapata-Mina Juan , Tibaquirá Juan E. , Castillo Juan Carlos
Published: July 2023

The objective of this study is to determine whether current electric power generation practices in Colombia will cover future electricity demand in a sustainable manner. For this purpose, a projection of a current trend scenario was made using the Autoregressive Vectors model, and the results were compared with the projected electricity demand for the country to the year 2030. An analysis of generation efficiency as a technical indicator, of primary energy intensity as an economic indicator, and of carbon emission intensity as an environmental indicator was carried out. It was identified that starting in 2025, electricity generation will not be able to cover the country's electricity demand at its upper limit, and by 2030 demand will exceed generation in its medium scenario. Therefore, it is advisable to implement energy efficiency strategies that will either reduce end-user electricity demand or increase electricity generation by 2025. On the other hand, the country's electricity generation process tends to increase its η and reduce both its IEP and IEC by 2030, which indicates that the rate of improvement of electricity generation practices in Colombia, which is implicit in the historical data analyzed, will be sufficient to achieve sustainable generation in the future.
Harnessing Group-Level Influence to Boost Energy-Savings Behavior in the Office Building
Authors: Do Tuan Anh , Nguyen Tung Thanh , Duong Kien Trung
Published: July 2023

Using energy saving and effectively is one of the measures to ensure energy security in urban areas. Research on energy-saving behavior in buildings is one of the approaches to improving energy usage efficiency. This study explores the mechanisms that influence the energy-saving intention (EI) and energy-saving behavior (EB) of individuals in shared spaces, including the Self-transcendence group Values (SV), Descriptive Norm (DN), Group Interaction (GI), and Energy management board (MB). The research model proposed ten hypotheses based on the theory of Dynamic group, and data was collected through a direct survey questionnaire from 295 samples and analyzed using Structural Equation Modeling (SEM). The results show that descriptive norms, i.e., the actions of other members in the group, have the highest impact on the energy-saving behavior of individuals in shared spaces. Group interaction helps to increase the likelihood of acting and, therefore, reinforces the intention to save energy. The Energy management board indirectly influences the energy-saving behavior of individuals through their intention to save energy. These findings can contribute to the development of energy-saving strategies in shared spaces, focusing on descriptive norms, rather than the current approach based on instructions. Furthermore, the experimental research results can provide guidance for policymakers in developing strategies to change energy-saving behavior in buildings in urban areas in Vietnam.

This study systematically reviews the journey of carbon accounting research published in international journals ranging from 2011-2022 to provide future directions of research. This paper aims to provide an overview of key themes in carbon accounting development over the past 12 years. This study analyzed 62 articles from Scopus database research journal from 9 countries published in 21 journals. This bibliometric study uses content analysis with QSR Nvivo software. Carbon accounting research development starts from counting to accounting field, but no one studied the accountability of carbon emission. Most of the samples studied carbon emission in corporate level compared with city, national, product, or project level. More than half of the samples use qualitative method, especially case study. Research on Carbon Accounting still allows a lot of development, especially in the measurement and disclosure of carbon emission. The accountability of carbon accounting also needs further analysis. This study contributes to the existing literature of carbon accounting research stream and provides suggestions for future research. Accounting standards setter can start to regulate the recognition, measurement, presentations, and disclosure of carbon emissions. Auditing standards setter also can start to regulate the auditing procedure of carbon accounting.
The Natural Resource Curse: Is It Really a Curse?
Authors: Algharabali Barrak Ghanim , Al-Thaqeb Saud Asaad
Published: July 2023

The Natural Resource Curse literature started with a clear consensus that dependence on natural resources have clear direct negative effects on economic growth and levels of democracy. However, the literature today reflects that the debate is still going where several papers reflects evidence that is against the consensus of the Natural Resource Curse hypothesis, which provides many open avenues for further research. This paper surveys the literature of the natural resource curse and identifies the main arguments and findings of both streams (curse stream and blessing stream). The main point that this paper highlights is that the literature is still not clear 100% whether the natural resource is a curse or a blessing. The econometric technique and the way how you define natural resources could lead to different or opposite results.
How do Climate and Macroeconomic Factors Affect the Profitability of the Energy Sector?
Authors: Joaqui-Barandica Orlando , Manotas-Duque Diego F.
Published: July 2023

This research identifies the significant relationships between climate and macroeconomic variables with the financial profitability (ROA) of energy sector companies in Germany, Norway, France and Spain. We work under the hypothesis of the existence of non-linear relationships for which we fit a Generalized Additive Model (GAM) for each country. We find that macroeconomic variables are often considered more important for modeling profitability than climate variables. This is because general economic conditions, such as interest rates and commodity prices, can have a broader and deeper impact on a firm's financial performance than local climate variations. However, climatic conditions are relevant if the specific industry consists of renewable energy companies. The results of this study can be very useful for financial analysts and investors, as they can adjust their business strategies to improve their financial performance.
The Relationship of Energy Generation from Fossil Fuels, Low Carbon Resources, and Renewable Resources and Inflation within the Framework of Taylor’s Rule: The Case of Kazakhstan
Authors: Niyetalina Gaukhar , Balapanova Elmira , Kuralbayev Almas , Lukhmanova Gulnar , Bolganbayev Artur
Published: July 2023

This study analyzes the relationship between energy production from fossil fuels, low-carbon sources, and renewable sources and inflation in Kazakhstan from 2000 to 2021, using the VAR method within the framework of the Taylor rule. Energy production is categorized under two headings, namely from fossil fuels and from other sources. While examining the relationship between energy production from fossil fuels and inflation, the interest rate and GDP growth rate, which affect inflation, were also included in the model as control variables following Taylor's rule. Thus, the relationship between energy production from fossil fuels and inflation can be analyzed more realistically. Energy production data are obtained from Our World in Data, GDP data from the World Bank site, and interest and inflation data from the ADB Data Library. The study showed that the interest rate affects inflation following the Taylor rule. We found a significant relationship between energy production and inflation in Kazakhstan. The relationship is that energy production from fossil sources increases inflation, while energy production from other (renewable and low-carbon) sources reduces inflation. This result once again proved the importance of energy production from renewable and low-carbon sources for Kazakhstan. Furthermore, the relationship between inflation and energy production proved not to be a causal one.
The Local Impact of Mining in Peruvian Districts: Evidence of a Subnational Resource Curse?
Authors: Bahlburg Fridtjof
Published: July 2023

In the early 2000s, Peru experienced a major mining boom as global prices skyrocketed. At the same time, the country implemented a revenue-sharing arrangement between the national government and subnational governments, to redistribute the newly gained financial windfalls. Using census as well as survey data, we compare producing and non-producing districts in order to determine the effects of mining transfers on local development. We find evidence that producing districts were characterized by better development than non-producing districts before the establishment of a transfer of mining rents (the so-called Canon Minero). These effects persist when comparing districts over time. Concerning the effect of Canon Minero transfers on local development, we find that these transfers, through district governments’ expenditures, contribute to a reduced poverty rate and increased per capita consumption when comparing producing as well as non-producing districts in producing provinces to non-producing districts in non-producing provinces.
Does Globalization Cause Environmental Degradation in Developing Economies? Evidence from Cote d’Ivoire Using Ecological Footprint
Authors: KEHO Yaya
Published: July 2023

This research examines the effects of globalization on environmental degradation in Cote d’Ivoire using data from 1970−2018. Previous studies in this area mostly focused on carbon emissions as indicator for environmental degradation. However, this study uses ecological footprint to cover different aspects of environmental degradation. Using the autoregressive distributed lag approach, the results disclose that globalization worsens the environmental quality by increasing ecological footprint. Furthermore, the results demonstrate a positive and monotonic relationship between economic growth and ecological footprint. The decomposition of globalization into different dimensions reveals that economic, social and political globalization contribute to environmental degradation. On the basis of the findings, some recommendations are suggested to tackle environmental degradation.
The Place of Gulf Basin Energy Resources in EU Energy Security
Authors: Sarkhanov Teymur , Muradzada Imangulu
Published: July 2023

The article discusses the importance of Gulf Basin energy resources in ensuring energy security for the European Union (EU). The Gulf region is a major source of oil and gas for the EU, which is heavily dependent on imports to meet its energy needs. The article highlights the various challenges faced by the EU in securing its energy supply from the Gulf region, including geopolitical tensions, price volatility, and the need to diversify its energy mix. It also discusses the role of renewable energy sources in reducing the EU's dependence on Gulf energy resources. Overall, the article argues that the Gulf Basin will continue to play a critical role in meeting the EU's energy needs, and that efforts must be made to ensure the security and stability of this energy supply. However, the article also suggests that the EU should explore alternative sources of energy and reduce its reliance on Gulf energy resources. It notes that the EU has made significant progress in promoting renewable energy and energy efficiency, and that these efforts should be continued and expanded. Another important point raised in the article is the need for cooperation between the EU and Gulf countries to ensure energy security. The EU must engage in dialogue with these countries to address common challenges and promote mutual interests. In conclusion, the article provides a comprehensive overview of the role of Gulf Basin energy resources in EU energy security. While acknowledging the importance of these resources, it also emphasizes the need for diversification and cooperation to ensure a stable and sustainable energy supply.
Public Funding for Energy Innovation and Decarbonization Goals: A Coherence Challenge
Authors: Ratner Svetlana , Gomonov Konstantin , Revinova Svetlana
Published: July 2023

This study is devoted to assessing the impact of public spending on research and development in the field of energy efficient technologies on achieving the goals of decarbonization and improving the energy efficiency of the economy. Using the two-stage Data Envelopment model, the study identifies countries with the highest and lowest efficiency of the national energy efficiency innovation support system. It was revealed that the most noticeable reduction in the carbon intensity and energy intensity of the economy in the medium term is demonstrated by countries that pay more attention to the introduction of organizational and social innovations related to changing consumer behavior (Brazil, Spain). Countries that are accumulating knowledge in radically new technological areas demonstrate the low efficiency of the innovation system at the implementation stage in the medium term (Japan, South Korea, US).
A Systematic Review on Nexus Between Green Finance and Climate Change: Evidence from China and India
Authors: Shah Shangram Bahadur , Sopin Jirakiattikul , Techato Kua-Anan , Mudbhari Bibek Kumar
Published: July 2023

The efforts of developing economies are mainly concerned with integrating different socio-economic requirements. In contrast, those economies only concentrate on the immediate impact to be resolved instead of focusing on efforts to mitigate long-run effects such as climate change: a global challenge due to long-term shifts in weather and temperature pattern. Climate change has resulted in global warming, severe storms, and increased droughts, including risks to human health, loss of biodiversity, poverty, and displacement, whereby green finance is considered a primary solution to mitigate such problems that can ensure sustainable environmental outcomes while promoting the agenda of, decarbonization, green tech innovation, green financial innovation, and green growth. This systematic review paper studies the nexus between green finance and climate change in China and India. This article follows Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines and reviews Scopus and Web of Science indexed peer-reviewed articles of five years published from 2018 AD to 2022 AD and 58 full-text articles were reviewed. The paper's significant findings reveal that innovation in finance and technology are the major frontiers of green financing that are critical in addressing the problems of climate change. It is environmental regulations that accentuate the process of green financial innovation and green technology innovation. However, green financial innovation is also a catalyst for green technology innovation. Green financial innovations are related to developing and innovating green financial products such as green bonds or loans, green insurance or securities, ESG rating, perception of environmental issues, and carbon drifting. On the other hand, green tech innovations are innovations in energy, transport, construction, and buildings. Innovations in technology and finance backed by environmental regulations strengthen the effort toward decarbonization. Regulatory interventions in green financing have more pronounced effects on emission reduction. Such actions are oriented towards green growth where the desired sustainable outcomes are realized regarding climate change adaptation, mitigation, or carbon neutrality.
Energy and Agricultural Development in the Red River Delta Provinces, Vietnam
Authors: Thuy Duyen Dang Thi
Published: July 2023

Agriculture is a traditional industry in Vietnam in general and the Red River Delta in particular. Agriculture has created many jobs and incomes for laborers in the locality and neighboring provinces over the past time. However, the production and consumption of energy such as gasoline, gas, petroleum and fuel in the Red River Delta are concerned and focused by local authorities and people. In particular, they emphasize green agriculture. This study investigates the long-term cointegration relationship between energy production and consumption on agricultural development and local economic growth. The author used long-term data of eleven provinces for calculation. The experimental results demonstrate that the independent variables explain 53.5% of the variation of the dependent variable and the rest (46.5%) can be explained by other causes. The research results show that 4 factors are agricultural labor (La), agricultural revenue (output) (REV), agricultural investment capital (Ia) and production and consumption of petroleum and gas (PE) has a positive impact on agricultural production value. The factor of energy production and consumption (EG) has a negative impact on the value of agricultural production in the Red River Delta. From there, the study proposes ways to use more efficiently the existing energy sources in the Red River Delta.

Authors: Gogolova Martina , Vartiak Lukas , Kovalova Erika
Published: July 2023

Nowadays, the problem of environmental pollution and damage extends beyond the borders of individual countries. Thanks to progress in the scientific and technical field, the impact of human activity on the environment has been significant, which has caused damage and reduced the overall value of the surrounding environment. The paper aims to point out the environmental responsibility of companies in the field of public passenger transport as one of the possible forms of obtaining a better competitive position. An essential step in processing this issue was obtaining theoretical knowledge regarding the environmental responsibility of companies. We gained theoretical knowledge by studying domestic and foreign literature, emphasising scientific works devoted to the solved problem and published in impact journals. We applied the theoretical knowledge to a specific company in Slovakia's public passenger transport field, making it easier to understand the problem. As a result, more ecological and economic measures in the business to prevent environmental damage and reduce costs are to be introduced. To conclude, the analysed company could use saved funds for marketing activities to acquire new and retain current customers or improve its current competitive position.

Published: July 2023

This study analyzes the causal relationship between the highest price formation and trading volume in Energy Company stocks traded on KASE. In addition, Granger causality analysis is strengthened with frequency domain causality analysis to determine the concentration points of the causality relationship. This aspect provides vital decision support, especially in investment decisions. Three different relationships are identified for the causality between the highest price formation and the transaction volume. There is a two-way causality relationship for KEGC and a one-way for KZTO. No causal relationship was found for KZAP. These results can be interpreted as an indication that the Kazakhstan stock market offers a rich portfolio for investors. The causality structure of the investment climate in Kazakhstan can be analyzed by similar studies on the composite index and other companies traded in KASE. The time interval of the study was determined as between 01.01.2021 and 31.01.2023 and the data used were retrieved from the investing.com website.

Authors: Shakharova Aliya , Alamanova Chinara , Olshanska Oleksandra , Kafka Sofiia , Tuts Ilona , Dugalova Gulnar
Published: July 2023

The disruption of the energy system at the global and local levels requires an intensification of public policy in this area to respond quickly to changes. Strategic planning and public policy changes are needed to ensure the sustainability of the energy sector. In the short term, Ukraine's priority should be improving energy security. Natural gas will be essential in balancing electricity on the road to decarbonization. The transition to renewable energy sources can achieve natural gas self-sufficiency. The article analyzes the directions of energy security and normative and legal regulation in the energy sector. It is established that the main direction of transition to decarbonization in an unstable external environment is public-private partnership mechanisms. The introduction of this mechanism provides benefits for all interested parties. In order to choose the most effective form of public-private partnership, a flowchart of analysis and evaluation of environmental and economic efficiency was developed. This flowchart applies to decarbonization projects and considers regional features of the energy sector and differences in readiness for the transition to the decarbonization of different countries. Limitations of the model application are the imperfect regulatory framework and the high instability of the external environment. The main objective is to simplify the procedures for attracting investment in the energy sector and reduce the time for project preparation and submission, which will help to implement the most effective projects in the short term and make the transition to decarbonization in the long term.
Renewable and Non-renewable Energy Consumption, CO2 Emissions, and Responsible Economic Growth with Environmental Stability in North America
Authors: Mendoza-Rivera Ricardo Jacob , García-Pérez Luis Enrique , Venegas-Martínez Francisco
Published: July 2023

This paper examines the impact of the consumption of non-renewable energies (gasoline and gas), as well as the consumption of renewable energies (solar and wind) and CO2 emissions (one of the main pollutants) on Economic Growth (EG) in North America. The data comes from the public sources of the World Bank and British Petroleum annually from 1966-2020. A Vector Autoregressive (VAR) model is estimated to analyze relationships among the variables under study. Likewise, tests to confirm the non-presence of serial correlation in the residuals of the VAR are carried out. Subsequently, Granger causality tests and an analysis of impulse-response functions are performed. The EG for Canada is explained by a lag from the previous year with a small positive effect. Likewise, the Consumption of Non-Renewable and Renewable Energies (CNRARE) similarly affects EG in a slightly negative way and CO2 emissions are not significant to explain EG. The US and Canada share similar dynamics concerning CNRARE, but the CO2 emissions that accompany the industry do positively affect growth. Mexico differs from Canada and US in that the consumption of non-renewable energy (NRE) has a positive effect on economic growth, although it is not significant, and CO2 emissions negatively affect EG. This is due to a timeless change in industrial development that US and Canada went through previously in their process of industrialization and technological modernization. Finally, in Mexico and Canada, unlike US, a positive response from the EG is observed due to a shock from renewable energy. This investigation differs from current literature in the following: 1) many studies have been carried out on the subject in many countries and regions, but none have addressed the case of North America, to the extent that the authors are aware, 2) conducts an assessment of responsible growth with environmental stability in North America, and 3) provides public policy recommendations to promote the use of renewable energy in all sectors of production while respecting the environment in the long term.

The stock price plays an important role in a financial market. In this research, the natural relationship of the daily stock prices of two energy companies, namely the daily stock price of ADRO and PTBA, from January 2018 to December 2022 will be discussed. The purpose of this research is to obtain the best model that fits the data of the daily share price of the two companies, ADRO and PTBA. The analysis used to model the data is the multivariate time series method. From the results of the analysis, it was found that the best model is VAR(3)-CCC-GARCH)(1,1). Based on this VAR(3)-CCC-GARCH(1,1) model, further analysis: impulse response function (IRF), granger causality, the proportion of prediction error covariances, and forecasting for the next 30 days are discussed. The granger causality test found that the ADRO and PTBA have mutual granger causality (bidirectional). The results of the IRF analysis explain: If there is a shock of one standard deviation in ADRO, ADRO and PTBA have a response. ADRO's response is positive for the next 24 days with a downward trend, while PTBA's response is positive with an upward trend; If there is a shock of one standard deviation in PTBA, PTBA itself and ADRO respond. ADRO's response is negative and weak and has a downward trend in the next 24 days, while PTBA's response is quite large and positive with a downward trend. From the forecasting results for the next 30 days (period), ADRO's closing price has decreased, and PTBA data has a downward trend for the next 30 days.

Shaping energy-saving behavior in education system plays huge and obvious role in economic and social development. While there is a large amount of literature covering the issues of technical advancements in implementation of energy-saving technologies, organizational and technical aspects of world experience, there is still a lack of publications exploring the scale and features of energy-saving behavior in education system. This paper analyzes features of shaping energy-saving behavior at three levels: school, university, and communities. It systematically reviews 119 WoS and Scopus studies, which allowed us to determine influence factors and prospects of shaping energy-saving behavior for the younger generation and community reps. The paper sets four research questions aimed at data analysis. The results showed (a) the lack of research on issues related to shaping of energy-saving behavior at the school and university levels; (b) that mainly, literature focuses on a comprehensive study of individual and socio-demographic factors affecting energy-saving behavior of communities; (c) that at the university and school levels, situational and individual factors have the greatest impact on energy-saving behavior of students; gaps in socio-demographic factor research; and d) as prospects of shaping energy-saving behavior of students, development of educational programs, implementation of state policy on energy conservation, information on energy conservation issues can be highlighted – all from the beginning of the COVID-19 pandemic to the present. The paper is intended for researchers, education and energy experts interested in possibilities of educational technologies in shaping energy-saving behavior.
