The paper defines the directions of improving turbogenerators as the basis for ensuring the energy independence of Ukraine. The analysis of the state, problems and prospects for the development of modern electric power industry. Goal of the work is to identify promising directions for sustainable development of the national electric power industry in order to ensure energy security of Ukraine, to conduct a comparative analysis of electricity sources, to confirm the need to improve the main sources – turbogenerators. Methodology. During the research, an analytical analysis of the electricity sources, which are installed at power plants in Ukraine and the world, was carried out, taking into account the growth of the planet's population and its energy activity. Cyclic theory was chosen as the theoretical basis for forecasting. On the basis of this theory, global development trends, advantages and disadvantages of currently used sources of electricity - thermal (including nuclear) power plants and stations that operate from renewable energy sources - have been established. A review of literary sources on the methods of the energy sector forecasting the development, including the development of the energy sector in Ukraine, has been carried out. Originality. It has been established that due to the active growth of the planet's population, with the increase in its energy activity, obtaining electricity from renewable energy sources is not enough, that for the next 20-30 years nuclear power plants will be the main sources of electricity. The internal and external threats to the energy security of Ukraine, directions of development of turbogenerator construction, ways to improve turbogenerators, to increase their energy efficiency, power per unit of performance, to increase the readiness and maneuverability factors, and overload capacity have been identified. Practical significance. The need to continue the modernization and improvement of the turbogenerators of nuclear power plant units, as the main sources of electricity, has been proved. The directions of their improvement are established: increasing the power in the established sizes, making changes to the design of the turbogenerators inactive elements, replacing the cooling agent to keep Ukrainian turbogenerators at the world level, improving auxiliary systems, improving and increasing the reliability of the excitation system, introduction of automatic systems for monitoring the state turbogenerators. Possible limits of use, advantages, disadvantages and problems of using renewable energy sources for Ukraine have been established.

The main purpose of this paper is to analyze and address the challenges of implementing green energy in Ukraine, in particular, to identify its advantages and disadvantages. The implementation of solar renewable sources—stations, panels, and batteries—is emphasized. The results of sociological surveys of Ukrainian public opinion on environmental issues, in particular, energy issues, are presented. The existence of public demand for renewable energy and the readiness of the population to use renewable energy sources are identified. A strategy for strengthening the country’s energy independence in the face of new globalization challenges is defined. General scientific methods as well as special methods were used in this paper: statistical analysis, secondary analysis of data from sociological studies of public institutions, and desk analysis of documents and reports from public services. In this paper, it is concluded that Ukraine is geographically and territorially attractive for green energy development and investment. It is important that there is a public and state demand in the country to strengthen the country’s energy security, in particular, through the introduction of renewable energy sources. Therefore, despite drawbacks and obstacles, green energy in Ukraine has great prospects.

Technology roadmaps are critical for decisions pertaining to technology development. They have been utilised in the renewable energy sector to assist in filtering alternative technology options in order to support energy policy formulation, energy security and energy independence, among others. However, solar aided power generation is a recent concept and no roadmap has been developed for the technology as yet. This paper thus reviewed the literature related to roadmapping with the aim of understanding the methods and tools that have been utilised in other settings. Informed by the literature, a conceptual framework was developed, which was further utilised for the initial analysis for developing a roadmap for solar aided power generation in South Africa. Generally, it would be beneficial for South Africa to integrate solar aided power generation within its current Renewable Energy Independent Power Producer Procurement Programme (REIPPPP) or the National Treasury Public-Private Partnership (PPP) programme. However, it should be noted that this is only feasible in the short- and medium-term. In the long-term, there is a need to support stand-alone solar thermal technologies.

The objective of the paper was to identify the potential of rural areas in Lithuania for the development of renewable energy. The research material and source of information were legal acts of Lithuania regarding the Programme of Rural Development for 2014-2020 of the Ministry of Agriculture of the Republic of Lithuania and National Energy Independence Strategy of 2018 Ministry of Energy, statistical data of the Department of Statistics of Lithuania and reports of institution related to renewable energy. The research covers the years 2007-2018 with a perspective up to 2050. The analysis shows that the share of renewable energy in the energy sector will continue to grow mainly due to the policy chosen by the state regarding energy security and environmental protection. Rural areas have a chance to take advantage of the state policy in order to improve their economic situation, including implementing innovations, reducing agricultural production costs, improving the local labor market and broadening and diversifying economic activity in general. The analysis shows that the largest share in RES will be played by wind and solar energy, and the share of biomass production will decrease.

Renewable energy, such as solar and wind, has been increasing in popularity for over a decade. This is especially true in rural, underdeveloped areas, and urban households that desire energy independence. Renewable energy sources, such as solar, provide enhanced environmental benefits while simultaneously minimizing the carbon footprint. One popular technology that can capture solar energy is solar panels. The demand for solar panels has been on the rise due to increases in energy conversion efficiency, long-term financial advantages, and contributions to decreasing fossil fuel usage. However, solar panels need a steady supply of sunlight. This can be challenging in many situations, geographies, and environments. This paper uses multiple machine learning (ML) algorithms that can predict future values of solar radiation based on previously observed values and other environmental features measured without the use of complex equipment with methods that are computationally efficient so that forecasting can be done on consumer premises.

During the current economic growth and the global climate crisis, energy supply is a pressing concern. Local energy sources are an essential part of sustainable development, and they also provide workplaces and energy independence. Various biding legislative documents oblige prioritising renewable energy sources (RES) and focus on green, local energy. Society cannot do such a transition without estimating the available resources and understanding the links among various factors influencing the energy market. The study aims to visualise system dynamics (SD) model parameters using the interactive cartography tool to analyse the potential of renewable energy in Latvia. Data gaps in the model were filled using statistical estimations and ArcGIS Pro spatial analysis. A JavaScript library for interactive maps Leaflet and HTML were used for the graphic user interface. The coupling presented in this paper is not dynamic but provides an insight into the potential implementation of the spatial data into models.
