Summary The growing energy demand in the world and the concern for environmentally damaging energy sources have led to an increased interest in seeking alternative renewable energy sources, such as wind energy. Furthermore, choosing effective locations for wind power plants has become a key issue in project planning. However, prior to implementation, such projects should be confirmed as economically viable. This article is a systematic review of the literature carried out with the aim to identify the main factors that impact the economic feasibility of wind energy investments. The search was performed in the ISI Web of Science (WoS) electronic database, from which 120 papers were extracted after a selection process, and were analyzed individually. As a result of the review analysis, 23 factors that have an impact on feasibility analysis were identified and organized in five categories: location (surface roughness, turbine location), economic (investment costs, operation and maintenance costs, avoided energy cost, depreciation, land rent), political (interest rates and taxes, energy sales price, inflation, financing conditions), climatic (wind speed, air density, temperature, air pressure), and technical (turbine height, installed wind power, lifetime, efficiency, rotor diameter, operation time, number of turbine blades, construction time). These factors can directly impact the cost of capital and/or energy production, affecting the economic viability of wind farms. In the last decade, there has been an exponential growth in publications about economic feasibility of wind investments. The wind investments growth has been accompanied by financial studies about this subject. This study provides insights on the main variables used in wind energy feasibility studies. The results may assist researchers and investors to identify the key parameters that are being examined in the literature, and to evaluate which ones should be considered in their study to ensure a sustainable development of power generation through the wind source.

“…From the analysis, the crisis resulted from reliance on the oil sector, with the nation's budget retrieving 50% of its revenues from the oil sector (Soltangazinov et al, 2020). The depreciation of the oil sector by up to 20% in payments in 2020 prompted the initiative in Kazakhstan to focus resources on non-oil sectors with recommendations to develop the sector and its exports (Yarova, et al, 2017). In the analysis by Atakhanova and Howie (2022), the authors follow the gender issue, which presents additional challenges in the energy sector.…”

Years of industrialization and reliance on energies such as oil and coal have resulted in global pollution on an unprecedented scale. Carbon footprint, destruction of forests, melting away of ice caps in the North Pole, and climate change have persuaded many to adopt a more sustainable growth. In the wake of this catastrophe, “green” energy is a phenomenon that takes a step toward sustained development. Green energy consists of innovative and cost-effective ways to address the global consciousness by switching to renewable energy, water resources management, waste reduction, etc. Green Fiscal Policy aims to align prices and mobilize resources for climate change and sustainable development. Many developed and developing countries like Kazakhstan are taking the initiative towards zero carbon emission and renewable energy. The challenges of implementing the required policies include overcoming the barriers of the status quo to establish a new Geo-political and economic system in Kazakhstan. Political and economic challenges persist despite its vision for 2050 that Green Economy influences. This report focuses on Kazakhstan's natural resources, topography, and renewable energy enterprises. The Green Fiscal Policy is closely examined over Kazakhstan's current investment efficiency scenario.

Among the scientific papers of a practical focus, it is possible to single out the research by I. V. Kolodiazhna and K. A. Bukrina, who analyzed and proposed the use of the main effective measures in the system of sustainable functioning of the enterprise [9].…”

Purpose. Formation of an economic and mathematical model as an economic platform for the protection of industrial enterprises in order to implement economic security in the frameworks of business process reengineering. Methodology. The following methods were used in the research process: methods of theoretical generalization and comparison, analysis and synthesis (to determine the meaning of the concept of “economic security of the enterprise”), statistical method (to analyze the initial data), economic and mathematical modeling of the compositional restructuring of an economic unit – an industrial enterprise (to determine conditions under which it is advisable to reengineer the business processes of an economic unit in order to form a platform of economic security). Findings. The results are determined by the fact that the theoretical provisions of the paper are brought to the level of specific proposals and have a form suitable for use in practical activities. An example of the practical application of the proposed economic and mathematical model is presented as illustrated by Pivdennyi Mining and Processing Plant (MPP) PJSC, where the essence of the given analysis is revealed. The obtained results proved their effectiveness and feasibility of use at the relevant domestic industrial enterprises. Originality. For the first time, an approach to the development of economic security of the enterprise on the basis of business process reengineering has been proposed. Economic-mathematical modeling has gained further development in determining the conditions for the feasibility of implementing structural transformations of an economic unit to obtain optimal values of indicators that reveal the essence of the economic security of an industrial enterprise. Practical value. The analysis of modeling results makes it possible to propose the implementation of imperatives – economic security of the enterprise on the basis of the implementation of its restructuring. Application of the proposed model provides a means to ensure rapid adaptability of industrial enterprises to changes, high flexibility and adaptability of all elements of the system, autonomy and economic functioning of enterprises as a whole and their structural subdivisions. The practice of using the developed economic and mathematical model based on reengineering confirmed the obtained theoretical results.
