Two of the important topics concerning scientists and governments are blockchain and climate change. After the paper of Satoshi Nakamoto, blockchains became a global phenomenon. After its usage for cryptocurrencies, blockchain is starting to be used for digital protocols and smart contracts. Blockchain technology is used in many sectors, such as banking, finance, car leasing, entertainment, energy, etc. Climate change leads to global warming, which means the long-term warming of the planet. Therefore, governments have made an effort to decrease global warming or keep it stable. One of the mitigation ways of global warming is to use renewable energy. Solar energy is one of the most used types of renewable energy sources, and also blockchain technology is widely used in this sector. In this chapter, the authors investigate the use of blockchain technology in the solar energy sector.

This paper focuses on the use of renewable energy sources in Serbia and the Republic of Srpska and their impact on the environment and climate change. Renewable energy sources used in Serbia are hydropower, solar energy, wind energy, biomass, and biogas. Renewable energy sources used in the Republic of Srpska are hydropower, solar energy, biomass, and biogas. When using hydropower, the formed reservoirs often impact the microclimate of the environment in which they are located. Photothermal and photovoltaic solar radiation conversion installations are mostly stationary, do not emit harmful substances into the environment, and have no impact on climate change. The use of wind turbines has a certain influence on the flow of ambient air. When using biomass and biogas, combustion gases are released into the atmosphere, which has slightly negative impact on climate change. The paper concludes that the use of renewable energy sources in Serbia and the Republic of Srpska has a negligible negative impact on the environment and climate change.

The purpose of the article consists in the analysis of the norms of national and international legislation for the elimination of the discrepancies in the legal understanding of the definitions in the field of alternative energy, that is definition and scientific and theoretical substantiation of the notions «alternative sources of energy», «non-conventional sources of energy» and «renewable sources of energy», which will serve for the elimination of terminological discrepancies in national legislation, and will become a basis for uniform practical use of the latter in the field of alternative energy. Urgency of the research is conditioned by the reorientation of world energy sector in the direction of the substitution of conventional fuel sources for those alternative. Since global warming and increasing of the level of anthropogenic emissions as a result of human activity is one of the biggest ecological problems of the universe, international community, together with ecologists and climatologists of all the world are involved in the development and implementation of highly efficient international strategies, which are directed at the decrease of harmful impact of anthropogenic emissions on surrounding natural environment and human health. In order to prevent the climate change and to mitigate global warming the scientists of the entire world proposed a wide range of variants for the mitigation of climate changes of Earth. Among which the key place belongs to alternative and renewable energy sources, which have been identified as the main strategically successful directions of reducing anthropogenic emissions into the natural environment. Today, we can see a trend towards a reorientation of the global energy sector to more environmentally friendly, alternative and renewable energy sources and a departure from traditional fossil energy resources. At the same time, unambiguous interpretation and understanding of the conceptual and terminological apparatus is an important condition for the development and practical use of knowledge. Therefore, it is important to delineate the clear boundaries of the technologies included in the concepts of alternative and renewable sources of energy, as there are differences in the use of these concepts, both in national legislation and between national and international legislation. The article analyzes and systematizes the knowledge as to the categorial instrument in the field of alternative energy and proposes the definition of renewable and alternative energy sources in accordance with the rules of construction of conceptual and terminological apparatus taking into account international experience in this field. The proposed wording of these concepts serves to eliminate terminological inaccuracies in national legislation, and will address the gaps between national and international legislation in the field of application of the categorial instrument in the field of alternative energy.

One major problem in the world is global warming that is now in the concern of some countries. Most countries are working on the usage of renewable energy sources such as solar energy, clean fuels like hydrogen and also increasing the efficiency of fossil fuel plant to help the global warming effect. Countries having high potential of solar energy and also natural gas as a source of hydrogen can use the finding of this research by developing usage of the solar energy converters and natural gas fuel cells for electric power plants. This paper discusses hybridization of renewable solar energy source with high efficient and clean usage of natural gas fossil fuel. Other aspects of this hybrid power plant is using the renewable energy sources as a reliable power supply with stand alone and grid connected capability which can increase network power quality. This paper also discusses the hybridization of solar energy as a renewable energy source and natural gas fuel cells as a fossil fuel and also improvement of power plant efficiency by using power electronics technology and electric energy storages.

Over 90% of Uganda's power is generated from renewable sources. Standardised Implementation Agreements and Power Purchase Agreements create a long-term relationship between Generating Companies and the state-owned off-taker guaranteed by Government. The COVID-19 pandemic and measures to curb the spread of the virus have triggered the scrutiny and application of force majeure (FM) clauses in these agreements. This article reviews the FM clauses and considers their relevance. The authors submit that FM clauses are a useful commercial tool for achieving energy justice by ensuring the continuity of the project, despite the dire effects of the pandemic. Proposals are made for practical considerations for a post-COVID-19 future which provides the continued pursuit of policy goals of promoting renewable energy sources and increasing access to clean energy, thus accelerating just energy transitions.

In this study we aimed to determine the extent to which changes in the share of renewable energy sources, their structural complex, and the level of energy security in Eastern Europe, Caucasus and Central Asia (EECCA) countries in the medium- and long-term are interconnected. The study was performed through modeling and determination of the structural characteristics of energy security in the countries. The methodology of the approach to modeling was based on solving the problem of nonlinear optimization by selecting a certain scenario. For the study, the data of EECCA countries were used. The ability of EECCA countries to benefit from long-term indirect and induced advantages of the transformation period depends on the extent to which their domestic supply chains facilitate the deployment of energy transformation and induced economic activity. This study provides an opportunity to assess the degree of influence of renewable energy sources on the level of energy security of countries in the context of energy resource diversification. The high degree of influence of renewable energy sources on energy security in the EECCA countries has been proven in the implementation of the developed scenarios for its increase. Energy security is growing. At the same time, its level depends not only on an increase in the share of renewable sources but also on the structure of energy resources complex of countries, and the development of various renewable energy sources. Therefore, today the EECCA countries are forced not only to increase the share of renewable energy sources but also to attach strategic importance to the structural content of their energy complex.
