Social capital is currently perceived as one of the basic factors of economic development and economic success of enterprises. However, while there is already much research on social capital in enterprises, there has been little such research in the energy industry. The aim of the publication is to fill the gap in this regard. The basic question that the authors try to answer is whether there is a higher level of capital in energy companies compared to other industries, and if so, what the reasons are for this. Apart from answering this question, the authors present their own method of measuring the level of this capital. The first part of the article presents the results of a study on the level of social capital in Polish energy companies, whereas the second part compares the levels of social capital in energy companies and industrial companies in other sectors. According to the study, energy companies generally have higher levels of social capital than companies in other industries. It has been found, however, that individual forms of capital that comprise social capital differ. The most significant differences were observed in relational capital, followed by cognitive capital at a lower value and structural capital at the lowest. The survey also revealed that there is a difference in social capital levels among the researched professional groups: management, administration, and production.

Vietnam became the world’s third largest market for solar photovoltaic energy in 2020. Especially after the Vietnamese government issued feed-in tariffs for grid-connected solar photovoltaic systems, the installed capacity of solar photovoltaic applications exploded in 2019. From studies carried out in the relevant literature, it can be said that support policies are highly important for the initial development of the renewable energy industry in most countries. This is especially true in emerging countries such as Vietnam. This paper reviews the feed-in tariffs issued and deployed in different regions of Vietnam for grid-connected solar photovoltaic applications. Moreover, the paper takes a closer look at the costs of electricity production from these systems in relation to the feed-in tariffs issued in Vietnam. The results show that the gap between the levelized cost of electricity and the feed-in tariff for solar photovoltaic electricity is relatively high, particularly in regions with a lower irradiation potential.

This paper uses the 5-five-minute high-frequency data of energy-listed companies in China's A-share market to extract the jump of energy stock prices and build a dynamic stock price jump complex network. Then, we analyze the clustering effect of the complex network. The research shows that the energy stock price jump is an important part of stock price volatility, and the complex network of energy stock jump risk has obvious time-varying characteristics. However, the infection problem of stock price jump risks needs specific analysis. China's coal industry has an important influence on the development of China's energy industry. According to the clustering analysis results of the network community, the clustering effect of the network community has time-varying characteristics. After October 2017, the clustering effect of the jumping risk of the coal industry and the new energy industry is obvious. The risk contagion within the new energy industry community is a key point for the development of the new energy industry.

The current energy transition from a fossil-fuel-based economy to a zero-carbon has significantly accelerated in recent years, as the largest emitters have committed to achieving carbon-neutral goals in the next 20-30 years. The energy industry transition is characterized by modernization through digital technologies, increased renewable energy generation, and environmental sustainability. Blockchain technology can play a significant role in providing secure digital distributed platforms facilitating digitization, decarbonization, and decentralization of the energy systems. Several promising blockchain applications in the energy sector are under research and development, including peer-to-peer energy trading; carbon monitoring, management, and trading; and IoT-enabled electric grid management. However, several challenges are slowing down the commercialization of these applications, including outdated legislation and regulations, slow pace of adaptation from the traditional energy industry, and risks associated with the new, untested technology.

The issue of cybersecurity of the domestic energy industry has been studied. The strategic principles of increasing the level of cyber resilience of communication and technological systems of energy industry enterprises are considered. The positive experience of the United States and the United Kingdom on the organizational and legal framework for preventing and minimizing encroachment on critical energy infrastructure is highlighted. The methodology of cyber threat analysis and risk assessment of cybersecurity violations of energy infrastructure facilities is detailed. The issue of cybersecurity of energy facilities and automated systems is generalized. The initiatives and directions of activity of the National Security and Defense Council of Ukraine for the purpose of development of cybersecurity of power systems are opened. The directions of the improvement to the formation of conceptual foundations for cybersecurity in the energy sector of Ukraine are identified.

The paper presents the degree of accumulated depreciation of fixed assets in Polish energy companies against the background ofglobal energy companies. The coal-fired energy units used in the Polish energy industry are outdated and require replacement. Inthe course of the energy transformation, they will be replaced with energy from renewable sources, natural gas and nuclear fuel. Thetransformation of the energy sector will allow the achievement of climate and environmental goals. Depreciation charged to expenseis an internal source of financing for processes of restoration of the production capacity. However, the Accounting Act and the IncomeTax Act provide for different methods of calculating depreciation, which means that not all depreciation is tax-deductible and that itdoes not reduce the tax base. Reducing the discrepancies in legal solutions regarding the calculation of depreciation in companies maystimulate the implementation of the processes of energy transformation.
