The Cost

From early 2019, South Africa and Russia have planned to increase their energy trade. Russia can become one of the world’s five largest energy exporters. This study examines of the cost of a kilowatt of electricity generated by coal power projects in South Africa and compares nuclear electricity with other types of green energy. This method must help to improve the management decision-making process in South Africa for energy exporta. Reasons for this persistence include the marketing strategies of Russian companies for seeking new markets in industrialised and postindustrial countries where, due to intensive competition, sales of Russian high-tech products are often unsuccessful. Renewable energy gives a chance to potentially reduce poverty in South Africa. The study concludes that imported crude oil is more suited to the needs of the refining industry of South Africa. The consumption for this type of energy in areas not concerning industry is insignificant and its increase is unlikely to be observed in the future. Highlights• Nuclear energy is popular energy source in South Africa now.• Provision of sustainable energy services helps to find the sources for economic growth. • Renewable energy technologies have opportunity for reduce nuclear production in South Africa.• Bio-energy can become the main source of energy in South Africa.

Energy Projects

Small green energy projects are considered an important tool to help poor people achieve sustainable development goals. However, green projects' economic results do not always compete with the traditional energy business. The main reason is the imperfection of the existing renewable energy technologies and the comparatively high energy generation cost with their help. The example of Ukraine, which significantly depends on fossil fuel import and develops renewable energy with state support, shows that green energy competitiveness problems exist within the overall energy market, i.e., convenient energy technologies. The key barriers to increasing the competitiveness of small green energy projects are the lack of available financial resources, the inconsistency of state energy policy, energy pricing gaps, etc. These factors significantly inhibit the spread of green energy technologies in the domestic economy. The competitiveness assessment of the renewable energy business model on the example of a private rooftop solar photovoltaic power plant has proved that green energy generation is available to every household and small business owner and is economically profitable due to existing government support mechanisms. Today, there is no competition in the Ukrainian renewable energy market, so creating a business in this field is relevant. In the long run, competitive green energy projects will provide reasonable electricity prices for consumers and profits for energy producers and stimulate the energy sector's decarbonization. Further directions for improving public policy in the green energy industry are continuing energy pricing reforms, expanding energy efficiency programs focusing on demand management, creating new jobs, and increasing investment in renewable energy sources to ensure energy security and greenhouse gas emission reduction.

The Impact

Magnetic materials specifically permanent magnets are critical for the efficient performance of many renewable energy technologies. The increased reliance on renewable energy sources has accelerated research in energy-related technologies the world over. The use of rare-earth (RE) metals in permanent magnets continues to be a source of greater concern owing to the limited RE supply coupled with dwindling reserves on the globe. This review focuses on how this has impacted on the state-of-the-art magnetic materials that continue to play a pivotal role in driving renewable energy technologies. Magnetic materials are perceived as key in driving the 21st century industrial revolution, and the participation of South Africa in this energy paradigm is critical in driving a new industrial revolution within the African continent. A number of opportunities are highlighted, and clarity is given on the several ubiquitous misconceptions and the risks on the heavy reliance on a single source for RE magnetic materials.

AbstractRenewable energy technologies (wind turbines, solar cells, biofuels, etc.) are often referred to as ‘clean’ or ‘green’ energy sources, while jobs linked to the field of environmental protection and energy efficiency are referred to as ‘green’ jobs. The energy efficiency of clean technologies, which is likely to reduce and/or eliminate reliance on fossil fuels, is acknowledged. However, the potential contribution of green technologies and associated practices to ill health and environmental pollution resulting from consumption of energy and raw materials, generation of waste, and the negative impacts related to some life cycle phases of these technologies are discussed. Similarly, a point is made that the green jobs theme is mistakenly oversold because the employment opportunities generated by transitioning to green technologies are not necessarily safe and healthy jobs. Emphasis is put on identifying the hazards associated with these green designs, assessing the risks to the environment and worker health and safety, and either eliminating the hazards or minimizing the risks as essential elements to the design, construction, operation, and maintenance of green technologies. The perception that it is not always economically possible to consider all risk factors associated with renewable energy technologies at the beginning without hampering their implementation, especially in the poor developing countries, is dismissed. Instead, poor countries are encouraged to start implementing environmentally sound practices while transitioning to green technologies in line with their technological development and overall economic growth.

The assessment of impact of oil production economic activities on land pollution in Russia contributes to evolutionary management decision making. Oil industrial pollution affects negatively flora and fauna. Thus, its important to identify the level of its exposure and danger, the site of contamination. A system approach is needed. When studying the environment, its necessary to consider the presence of risk situations and stochastic irreversible changes. Its essential to identify the nature and type of soil contamination with petroleum products using high-tech tools, intellectual procedures. The work considers modeling of such situation, forecasting and identification of oil contaminants. The submodel of optimal termination of monitoring is also considered. Ending monitoring of environmental optimization will result in lower monitoring costs, since monitoring oilcontaminated environments is an expensive and complex technological mechanism, often requiring satellite data. The proposed algorithm for modeling and system analysis is based on situational modeling. Evolutionary modeling allows to adapt the procedure (methodology) of forecasting and assessment to environmental risk factors. It increases the accuracy (formalization and evidence) and completeness of conclusions, the efficiency of situation analysis, which affects manageability of risk both for the oil complex and for individual enterprise in the industry. The results of the research may be used for development of software tools, in particular expert and predictive systems. Situational models are needed when oil companies are solving multi-criteria and multifactor problems.

As many programs of scientific and technical cooperation of various fields are being successfully implemented between Ukraine and the EU, the author has set the goal of intensifying relations between Ukraine and Chile in the field of green energy. The cooperation Ukraine has had with the EU serves as an example of future cooperation between Ukraine and Chile. The text explores Chile’s experience in the field of green energy and, through the comparative example of such cooperation between Ukraine and the EU countries, shows that such interaction is a worthwhile endeavor. Based on an analysis of research materials, one of the priority areas of scientific and technical cooperation is the use of non-traditional renewable energy technologies. In Ukraine, and the EU, as well as Chile, there are objective factors (natural, resources, socio-economic, environmental- technological) that concern their development. It is interesting to note Ukraine’s scientific experience and implementation of these technologies and the organizational and economic support of them as priorities in the context of national and regional policy. All aspects of international scientific and technical cooperation, including through the exchange of intellectual products, make it possible to increase the effectiveness of forms of state support, the innovation, production and business activities of Ukraine and the corresponding development of producers and consumers' motivation towards using non-conventional forms of renewable energy technology.

Generating Matrix

Electricity is an essential basic need that the South African government needs to pay special attention. A continuous or uninterrupted supply of electricity is essential for industrial production and economic growth and development. Since South Africa is overly reliant on coal fired electricity generating technologies which are environmentally damaging, the move towards green energy technologies to form part of the electricity generating matrix is highly desirable not only to reduce environmental pollution, but also to increase the supply of electricity to meet rising demand. However, the adoption and implementation of green energy projects has not been that easy and progress has been far from satisfactory. This study was therefore consummated to assess the effectiveness of installed green technology in the area of Pinetown in Kwazulu-Natal. The study also investigated the technological challenges affecting the implementation of green energy projects in SME sector in Pinetown Kwazulu-Natal. Furthermore, the study also examined as to what extent technological challenges are affecting the use of installed green technology in the selected area of Pinetown in Kwazulu-Natal. This was followed by exploring strategies that could be implemented to improve effectiveness of installed green technology in Pinetown. A quantitative research approach was adopted. Data collection for this study was performed by distributing and collecting a structured survey questionnaire to respondents. Data analysis for this research was performed using SPSS.
