The electrical power sector plays an important role in the economic growth and development of every country around the world. Total global demand for electric energy is growing both in developed and developing economies. The commitment to the decarbonization of economies, which would mean replacing fossil fuels with renewable energy sources (RES) as well as the electrification of transport and heating as a means to tackle global warming and dangerous climate change, would lead to a surge in electricity consumption worldwide. Hence, it appears reasonable that the electric power sector should embed the principles of sustainable development into its functioning and operation. In addition, events such as the recent European gas crisis that have emerged as a result of the massive deployment of renewables need to be studied and prevented. This review aims at assessing the role of the renewable energy in the sustainable development of the electrical power sector, focusing on the energy providers and consumers represented both by businesses and households that are gradually becoming prosumers on the market of electric energy. Furthermore, it also focuses on the impact of renewables on the utility side and their benefits for the grid. In addition, it identifies the major factors of the sustainable development of the electrical power sector.

Adopting a new paradigm for social development implies a transition to a circular economy. The above requires the reduction of greenhouse gas emissions, the utilization of wastes, and the use of renewable energy sources. The most promising way is the use of methanol for industrial and transport applications. China is experiencing a boom in methanol production and its use in almost every sector of the economy. The purpose of this study was to reveal economic benefits, carbon dioxide emissions and the potential production of green methanol. Fuel price history, energy costs and fuel economy were used for economic assessment. Life cycle analysis to evaluate carbon dioxide emissions was applied. It was revealed that only the use of green methanol as a fuel results in decreases in well-to-wheel CO₂ emissions compared to fossil fuels. The potential methanol production by using recycled waste and wind power was determined. Its annual production can range from 6.83 to 32.43 million tones. On this basis, a gradual transition to a circular and methanol economy is possible. Policymakers are recommended to support green methanol production in China. It can result in boosting the application of vehicles fueled by methanol and can control CO₂ emissions.

Recently, the approaches of the Corporate Social Responsibility (CSR) in the renewable energy development have changed with the new global approach to sustainability. Today, CSR is an evolving and dominating business practice that integrates sustainable development into a company’s business model. The main focus of our paper is on the public relations of corporate social responsibility in renewable energy development. We show that a proper approach to public relations and resulting communication and dissemination of products and results should be sustained. This paper assesses the new pathways for executing public relations for CSR with relation to the renewable energy projects. The study analyses the impact of corporate social responsibility on energy companies, which are expected to make a positive contribution to the development of sustainable energy. We use both the overview of the theoretical concepts and literature as well as analyze the case of the “old” and “new” European Union Member countries represented by the Baltic States that yield many similarities but differ in their economic development to show the best practices of promoting CSR in sustainable energy development. Our results demonstrate that the implementation of corporate social responsibility can help to create more ethical and conscious sustainable companies and to build better relationships with the environmentally engaged citizens and loyal customers who are also concerned about the environment, health and well-being of their communities.

Currently the "green" economy is an important part of positioning in the international arena as an environmental component of sustainable development. Russia, as an active party in the international arena, supports resolutions on the "green" economy development and "green" financing tools for resolving issues of climate-resistant economic growth. Factors and trends in the Russian "green" economy development are radically different from most developed countries. At the same time, Russia has undeniable advantages in terms of preserving natural landscapes and the ecosystem services' potential. Russia also has huge and almost unused opportunities for "green" growth. Our article is devoted to these problematic economic issues related to the "green" investment development. It is a basis for environmentally sustainable evolution. We discuss the latest trends and facts in the the"green" economy development of Russia. In addition, we describe possible promising directions for its growth in the future. Our results can be interesting and useful for researchers and experts working in the field of strategic management, spatial development and innovation economics. It is attractive for stakeholders and politicians involved in the economics and environment issues.
