Assessing the region's energy provision

Abstract

This paper considers the task of ensuring the energy and environmental security of regions under the conditions of shortage of traditional energy resources. The method of expert assessments has been applied to justify the choice of types of acceptable energy resources that provide an increase in the relative energy supply of the territories of the regions. A list of factors from 6 groups has been devised and compiled that includes 27 indicators characterizing the technological, environmental, and other consumer characteristics of energy resources available for use. The maximum and minimum values of the indicator scores, the permissible intervals for their change, and the weighting coefficients that assess the importance of the indicator in the list have been determined. The method of expert assessments is supplemented by a random number generator for the formation of an information field on the values of the characteristics of energy resources and statistical processing of data on acceptable energy resources under the conditions of the considered regions. A quantitative comparative analysis of available energy resources and technologies based on them was carried out. It is proposed to use the acceptability index and the environmental conservation index as a criterion for the preference of a resource. Index values equal to or greater than 1 indicate resource preference. It is shown that for the base region under consideration, such resources are nuclear, solar, wind, and hydropower. The method of expert assessments makes it possible to get an objective idea of the acceptability of using a certain energy resource to ensure energy security, taking into consideration its environmental impact in a particular region of the country. A quantitative comparative analysis of the state of the existing structure of energy resources in the region and their availability has been carried out. To conduct a comparative analysis of acceptability by indicators and types of resources, a graphical and analytical methodology was used. The reliability of the results obtained was assessed using a concordance coefficient. The results could be useful for devising projects for the development and ensuring the energy security of the regions in the context of reforms

Assessment of the impact of the industrial enterprise on the environment by determining the integrated (generalized) energy efficiency performance indicator

“…If the enterprise provides electricity using only renewable energy sources, since the electricity is obtained without using primary energy resources, 𝑊 . 0 it will be in the expression (3), and the energy efficiency indicator is determined from the following expression: It is electric energy obtained from renewable energy sources, and this energy is considered as a primary energy resource at the same time; 𝑊 .…”

“…E.Evseev and T. Kisel studied energy efficiency indicators to ensure the integrity of the assessment of the activity of heat supply enterprises and summarized them in the section of the following indicators, i.e. technical efficiency, ecological efficiency, social efficiency, economic efficiency [3]. The system is complicated by dividing these indicators into several indicators for the state, managers and workers, enterprise owners and consumers.…”

Analysis of the season effect on energy generated from hybrid PV/WT in Malang Indonesia

“…Using indicators when developing the energy supply strategy, including utilization of renewable energy will promote systemic saving of fossil fuel, reducing the harmful effects of energy systems on the environment and energy supply stabilization [14]. Indonesia also needs to map hybrid PV/WT renewable energy by region as done like by [15], with this research it is possible to start mapping in Indonesia. Indonesia has a lot of cloves, so that fluctuating PV/WT hybrid energy is well used to dry cloves in an oven, such as the oven made by [16].…”
