Energy audit: types, scope, methodology and report structure

Abstract

<span>The objective of this paper is to study various methods adopted during the energy audit. Many countries are focusing on energy, not only enhancing the tenable power generation sources but also on utilizing the power more proficiently for economic utilization. The energy audit is an important parameter for all the developing and developed countries and they focus on energy efficiency, energy quality, and energy intensity. In the industrial, residential, and commercial sectors the top operating expense is found to be are material, machine, manpower, and energy. Identification of the energy-consuming sector is the prior attention to look for the energy-saving potential and quality improvement. Implementation of an energy audit can enhance the efficiency, quality of power, reduce the tariff of bills, and reduces the wastage of energy. The need for energy audits, different types of energy audits, various types of software used, and the energy audit report structure were presented in this paper.</span>

Comprehensive analysis of current research trends in energy storage technologies

“…Applications of these batteries are consumer electronics and utility/telecom backup. The cost of a NiMH battery is 0.99 $/Wh and it is a matured technology [43]. The disadvantages of NiMH batteries are limited long-term potential for cost reductions, more expensive than lead-acid batteries, high degree of self-discharge, low cell voltage, very low coulombic efficiency and it requires complex charging algorithm.…”

Exploring the Landscape of Energy Audits: A Bibliometric Analysis

“…An energy audit is a thorough evaluation that pinpoints energy use across various services and makes recommendations for energy-saving measures (Hassan et al, 2022). Energy efficiency, energy quality, and energy intensity are the three main areas of attention for energy audits, which are crucial for both developed and developing nations (Sharma et al, 2021).…”

Energy audits in the tofu industry; an evaluation of energy consumption towards a green and sustainable industry

“…Therefore, the energy audit in the tofu industry as a method of achieving the SDGs 7 (affordable and clean energy), 11 (sustainable cities and communities), and 12 (responsible consumption and production) (United Nation, 2024). The energy audit in this study is a toll to distinguish and examine energy administration programme, it could be useful for industry to save the fundamental energy cost and provides some advantages such as increasing profits, better quality, and the most essential fulfilment of leading towards contributing to the global energy saving (Sharma et al, 2021). To complete the literature gap, this study aims to investigate audit energy in the tofu industry as preliminary data, to evaluate consumption energy in different energy sources, to determine the production of wastewater in the tofu industries, and to find the energy sources available in the tofu industry.…”

“…To complete the literature gap, this study aims to investigate audit energy in the tofu industry as preliminary data, to evaluate consumption energy in different energy sources, to determine the production of wastewater in the tofu industries, and to find the energy sources available in the tofu industry. The energy audit reveals how much energy is needed for industrial activities through the tofu production process, which allowed us to figure out how to reduce energy consumption and more effectively (Sharma et al, 2021). Thus, it can become a reference for industry to improve industrial activities toward sustainability for environmental protection, such as the development of environmental technology, because it restricts the discharge of waste into the environment.…”
