This study seeks to estimate energy poverty using a multidimensional and wide-ranging category of indicators via the GRA-SRA approach. The study entails a case study analysis of the N-11 nations utilizing data from 2000 to 2017. Thus, a formulation of multidimensional energy poverty indexes of multidimensional indicators crosswise three dimensions is carried out. Energy availability, energy affordability, and energy cleanability, with regard to the N11 nations, are taken into account. The findings reveal that total energy poverty has progressed. We discover that Bangladesh (0.65) and Pakistan (0.47) are at risk concerning energy poverty, whereas the Philippines (0.36), Indonesia (0.33), and Vietnam (0.28) are less exposed to energy poverty. The relative changes in energy poverty are discovered among the N11 nations, where South Korea witnessed a consistent advancement in energy poverty, whereas Iran displayed a reduced trajectory and a vacillating trend. The findings indicate that the energy sources utilized for warming homes are essential within the scenario of energy poverty and inequality. Contrary to traditional steps, we assess the multidimensional energy poverty at the national level instead of the depths of gravity of energy poverty specifically for the energy-poor as against the whole population.

Renewable energy technologies play a crucial role in solving global energy and environmental issues, and the pace of the energy transition directly depends on improving their efficiency. Presently, the development and implementation of renewable energy systems are ensured mainly through state funding, the possibilities of which are limited. The potential of attracting private investments depends directly on their impact on companies’ profitability indicators, and the uncertainty regarding the return on investments is one of the main barriers affecting investors’ decision-making. Based on a vector autoregressive model for analysing the stationary time series, the paper explores the impact of long-term investments and research and development costs in renewable energy technologies on the financial performance of ten of the largest companies operating in this field. The study’s results showed that investments and spending on research and development positively affect such companies’ profitability indicators as earnings before interest, taxes, depreciation and amortisation, earnings before interest and tax, net income, and return on investment. The obtained results can be used to substantiate the economic effectiveness of investments in developing and improving renewable energy technologies when forming the companies’ financial policies to support them.

The agro-industrial complex (AIC) is becoming one of the main in the economy of Uzbekistan. In recent years, work has been carried out to reform it fundamentally. The normative and legal framework for its functioning has been formed, public administration has been improved. The market mechanism of management is being introduced. Investments are attracted. The structure of acreage is optimized by reducing cotton crops and placing fruit and vegetable crops on them. New intensive gardens and vineyards are being created, innovative greenhouses are being built. Work is carried out on construction and reconstruction of collectors and hydraulic structures, refrigeration chambers for fruit and vegetable products’ storage, introduction of new equipment and technologies in it. The processing industry is developing, the volume and range of products is increasing, including innovative and its export. Integration of producers and processors of agricultural products is intensifying. At the same time, there are still significant reserves in the agro-industrial complex of Uzbekistan. The efficiency in natural resources’ use is low. The irrigated agricultural land are is small. The technical and digital equipment of personal subsidiary farms and labor productivity in them are low. Uzbekistan is implementing a course for innovative development. The President of the Republic approved the Strategy for the agriculture development of the republic for 2020-2030. It sets the tasks of significant increase in the production and processing of agricultural products, expanding its range due to new types of products and its exports. The strategy is successfully executed. Nevertheless, it is necessary to improve the state management of the agro-industrial complex, the introduction of the market management mechanism, the development of interactions between the complex’s branches, strengthening export potential of the complex, introduction of innovations, digitalization of enterprises’ activities.

This paper is occasioned by the current events in the crude oil markets throughout the Covid pandemic time. The study analyzes the evolving nature of crude oil cost unpredictability caused by the variations that influence the crude sector throughout the current contagion. Every day's dataset is within the first month of 2020 and December 30, 2021 were measured by applying VAR and GARCH models. The results corroborate that the current contagion has adverse effects on the crude sector, primarily in two ways. It resulted in the headwinds for demand and cut international demand for crude oil, increasing uncertainty for major advanced and developing nations. Next, it resulted in output headwinds as the pandemic caused hydrocarbons conflicts among the leading crude supplying countries. The two headwinds seem to have caused the more than necessary crude unpredictability. Moreover, it was found that the United States output, total requirements, and crude-leaning demand shocks adversely affect the supply unpredictability of the United States and the extractive sectors. The findings depict that crude price instability responded significantly to the contagion caused by crude headwinds. Specifically, the study recorded the effect of uncertainty because of these headwinds beyond financiers' concerns about crude price instability. This study indicates that spillovers do not have meaningful forecast data, igniting critical debates concerning the relevance of the spillover indicator for predicting at minimal sampling occurrence.

Current study aimed to explore the nexus between energy and economic growth in post-communist nations during 1995-2014. As an empirical model, the growth model is employed including economic complexity indicator as a measure of capabilities for exporting sophisticated products. We employ Pedroni's (1999) panel cointegration tests and Panel Dynamic OLS estimation to assess the long-term link between the variables. At 1% significance level, we confirm cointegration between energy consumption and economic growth. Panel Dynamic OLS results revealed that economic growth positively influences energy consumption in Post-Communist states. The Dumotrescu and Hurlin (2012) panel Granger causality test results discovered unidirectional causality running from economic growth to energy consumption. Economic growth causes energy consumption in post-communistic countries, confirming the conservation hypothesis.

This paper examines for the first time the relationship between CO2 emissions and the consumption of renewable and non-renewable energy in Uzbekistan, spanning the period 1985-2020. The analysis uses the Autoregressive Distributed Lags (ARDL) model to estimate the long-run dynamic multipliers and short-run elasticity coefficients of energy consumption variables. Economic factors, such as GDP, are excluded in the analysis as they may cause multicollinearity problems. The empirical results document that in the short- and long-run, hydropower (renewable) energy consumption negatively impacts CO2 emissions per capita, showing a unidirectional causal effect. As regards with non-renewable energy consumption, natural gas and oil energy consumption have a positive impact on CO2 emissions per capita both in the short and long run. Coal consumption positively impacts CO2 emissions in the short run, while it is negative in the long run. Policy measures to enhance the collection of energy from additional renewable energy sources, in particular hydropower, should be taken into account in order to increase the share of renewable energy, and thus, to compensate non-renewable energy consumption which is the main contributor to CO2 emissions. Moreover, solar and wind energy should be explicitly taken into consideration as an additional renewable energy source, which has the lack of attention by policymakers. Furthermore, policy actions, such as the involvement of the private sector into renewable energy projects and the implementation of effective carbon tax policies, could be further options to reduce CO2 emissions.

Abstract In addition to the reliability of power supply quality of electricity consumers are one of the most important characteristics of the electrical systems. It has a significant impact on the efficiency of electrical receivers and the technical and economic performance electric networks. In the modern developed networks providing quality indicators of energy acceptable for consumers, requires significant cost of funds and materials, as well as the collection and processing of more information. This explains the importance of the questions of power quality in the complex problem of the design and operation of electrical systems. If the provision in the electrical systems normalized values of the frequency is mainly due to the balance of active capacity and characteristics of the appropriate equipment on the electrical stations, the quality of the voltage at the consumer is determined mainly by cost distribution networks. For consumer’s rural areas referred to the costs are most of the total production costs and electricity transmission, so questions quality assurance voltage networks always were in the focus of research, design, and operational organizations. Particular attention these questions acquire at present in connection with the rapid growth of electricity consumption in agriculture and the relevant development of rural networks. The huge positive effect electrification to fully manifest only when consumers are delivered electricity is quite high quality. Reduction of the quality of significantly impairs performance electrical receivers and leads to marked electro receivers damage.
