Inter-provincial power transmission in China solved the problem of electricity production and consumption spatial mismatch, which also facilitated Chinese green energy transition and sustainable development. Aiming to understand the spatial patterns and main driving factors, this paper accounted the aggregate carbon intensity per electricity produced by each province, built the inter-provincial Out–Destination matrixes of carbon emission embodied in power transmission among 27 provincial areas of 2006 and 2019, and quantitatively analyzed the change in spatial patterns of carbon flow and carbon intensity difference between power inward and outward provinces. We found that the inter-provincial power transmission has led to the reduction in the national average carbon intensity per electricity produced from 0.855 kg/kWh in 2006 to 0.628 kg/kWh in 2019 and the green energy transition of all provinces. The spatial morphology characteristics of carbon flow show the ‘three corridors of West-East Power Transmission (WEPT)’ pattern, in which power is transmitted from some main thermal power-dominated provinces in central and north-west China to the eastern coastal provinces. Further, it resulted in the carbon leakage from electricity consumption of the coastal provinces and carbon overload of the hinterland provinces. Despite natural resource endowment, the location of the provinces in the national power grid, the national low-carbon energy transition strategy, as well as advances in long-distance ultra-high-voltage power transmission technologies were the main factors to the formation and evolution of Chinese electricity green transition.

Visegrad Group

The aim of the research is to analyse the energy transition in the Visegrad Group countries, because they depend on the production of energy from the burning of fossil fuels, and transition is a huge challenge for them. The diversity of the energy transformation in the V4 countries was examined by using two qualitative methods, including literature analysis and comparative analysis. The timeframe of the study was set for the period from 2020 to 2030, as these years are crucial for the implementation of the European Green Deal Programme. Four diagnostic features were taken into account in the analysis: the share of RES in final energy consumption, reduction of CO2 emissions in the non-Emissions Trading System (ETS) sector, date of withdrawal of coal from the economy, and energy efficiency. The analysis shows that the V4 countries have different approaches and levels of energy transformation in their economies. Poland is in the most difficult situation, being the most dependent on the production of electricity from coal, as well as having the largest number of employees in the coal and around coal sector. The other countries of the group can base their transformation on nuclear energy, as each of them has at least four such power units. The increased use of biomass for energy and heat production is the most important stimulus for Renewable Energy Sources (RES) growth in the analysed countries. The ambivalent attitude of the political elite to unconventional sources in the four analysed countries significantly hinders the development of certain forms of green energy. However, it has been observed that an increasing proportion of the population, especially those living in regions of the country where there is no fossil fuel mining industry, has a positive attitude towards energy transformation. The study is the first that shows the state of involvement in the process of systemic change of the Visegrad Group countries. The results can serve as a starting point for understanding the reticence of this group of European countries towards the transformation phenomenon, as well as contributing to further research on the implementation of closed-circuit economies in the Visegrad Group countries.

AbstractHigh-voltage direct current (HVDC) transmission is known as green-energy transfer technology and has recently become an attractive alternative of high-voltage alternating current (HVAC) due to its high-power transmission capability and lower power loss. Use of composite insulators on direct current (DC) transmission lines experienced rapid growth in recent years due to their high hydrophobicity and better performance in contaminated environment than conventional ceramic insulators. During their service operation on DC lines, insulators are prone to more accumulation of contaminants due to unidirectional electric field. The contaminants under wet conditions allow leakage current to flow on the insulator surface. Being organic in nature, polymeric insulators have a tendency to age under the combined effects of electrical and environmental stresses. To fully understand the long-term aging performance of DC composite insulators, a detailed survey was considered necessary. Towards that end, this paper critically summarizes worldwide experience of aging performance of composite insulators in the field as well as in laboratory conditions.

The article discusses the main results of two major international summits held in October-November 2021, the key topics of which were the issues of the global fight against climate change and environmental protection. The decisions taken at these conferences, with the broad participation of world leaders, reflect the fundamental trends of the global environmental agenda. Within the framework of this agenda, Japan and the countries of Southeast Asia are building their modern energy and environmental cooperation. In this context, the article examines the main urgent tasks of energy-environmental interaction and sustainable development of Japan and the states of Southeast Asia. These countries are located in the Asia-Pacific region, which remains until now the main emitter of greenhouse gases in the world. However, the indicators of environmental pollution by Japan and the Southeast Asian countries are relatively not so high, compared to some other states in the region and the world. The article discusses the most relevant and significant examples of bilateral and multilateral cooperation between these countries in areas related to curbing global warming and climate protection. It has been revealed that with all the efforts made, since the 1990s, the indicators of reducing harmful emissions into the atmosphere in Japan remain modest and even lag behind some of the Western countries. The Southeast Asian countries show a serious attitude to the development of renewable energy, but their intention to abandon coal still raises some doubts about the methods of implementing this ambitious plan. In particular, it is currently not entirely clear whether these countries are preparing to make a full-fledged "energy transition" in the coming decades, or whether they just intend to replace their coal-fired thermal power plants with gas ones.

Significance Aluminium smelters are being hampered by high power prices and shortages amid the switch towards green energy sources. China has been forced to start importing aluminium at record levels to tackle domestic shortages. Impacts The green energy transition will strain power markets, increasing the challenge of producing energy-intensive aluminium. Supply will gradually diversify as outputs stagnates in China but looks set to rise in Argentina, Brazil, the Middle East and Russia. Consumers and governments in importing nations will increase aluminium recovery and recycling to cut pressure on the supply chain.

Received 13.01.2021. The coronavirus pandemic has accelerated global economic, technological and social transformation, including the energy sector, and has given the impetus to energy transition from organic fuels to clean energy sources. Though oil will remain an important energy resource in the global energy balance, in the long run renewables will become the leading energy. The European Union and China are the leaders in implementation of energy transition strategies from fossil to clean energy. The transformation in the energy market has affected dramatically the relations between producers and consumers, who now actively determine the consumption trends (for example, green energy, electric vehicles, etc.). Distributed generation and blockchain in power industry enable the consumers to play an active part in the electricity production and distribution chains. Digital transformation and climate agenda are changing the structure of energy business from vertically integrated companies to knowledge-intensive networks. Investors almost unanimously vote for renewable energy. The largest oil and gas companies change their long-term strategies and transform into energy holdings with the prevailing share of renewables in the business structure. Hydrogen attracts particular attention as a promising energy source. The EU plans to develop hydrogen transport infrastructure. For its part, Russia has the ability to supply hydrogen to the European market through the existing gas pipelines. Coronacrisis accelerated the development of online services, artificial intelligence, and distant work. Education and telemedicine received a powerful impetus for further development. Еducation becomes continuous process in the digital world. New educational ecosystems in which skills and competencies are worked out on an interdisciplinary basis are formed. Digital transformation meets the expectations of the generation Z, which in the coming decades will become economically active and will dominate in social and economic agenda. Digitalization, adaptive nature-like technologies, environmentally friendly energy resources, flexible horizontal network between market participants are already a post-COVID reality.

Clean energy transition is one of major transformation processes in the EU. There are different approaches among EU countries to decarbonization of their energy systems. The article deals with clean energy transition in France with the emphasis on power generation. While this transformation process is in line with similar developments in the EU, the Franch case has its distinct nature due to nuclear power domination in electricity production there. It represents a challenge for the current model as the transition is linked to a sharp drop of nuclear share in the power mix. It is important to understand the trajectory of further clean energy transition in France and its ultimate model. The article reviews the historical roots of the current model (which stems from Messmer plan of the 1970-es) and its development over years, as well as assesses its drawbacks and merits in order to outline possible future prospects. The conclusion is that the desired reduction of nuclear energy is linked not solely to greening process but has a complex of reasons, the ageing of nuclear reactors being one of them. Nuclear power remains an important low-carbon technology allowing France to achieve carbon neutrality by 2050. A desired future energy model in France can be understood based on the analysis of new legislation and government action plans. The targeted model is expected to balance of nuclear and green energy in the generation mix in 50% to 40% proportion by 2035, with the rest left to gas power generation. Being pragmatic, French government aims at partial nuclear reactors shut down provided that this will not lead to the rise of GHG emissions, energy market distortions, or electricity price hikes. The balanced French model is believed to be a softer and socially comfortable option of low-carbon model.
