“…Energy efficiency was considered differently, adapted to the context of the thesis, than the particular way described by existing sets of indicators (see Proskuryakova & Kovalev 2015); however, it was not the intention of this study to develop new energy efficiency indicators. The physical level was included and covered in Articles I and II.…”

“…The industrial level was partly covered by Articles III and IV, although the economic indicators were limited to supply costs of supplying wood chips to a CHP plant typically involving several enterprises, including fuel supply sub-contractors comprising numerous machines, eventually a terminal operating enterprise and the enterprise operating the plant itself. The macroeconomic level in energy efficiency indicator sets (see Proskuryakova & Kovalev 2015) was considered to be outside the scope of the thesis.…”

“…In this regard, Ang (2006) notes, "Defining this manner, energy efficiency reflects factors other than 'true' energy efficiency given by thermodynamic indicators." Proskuryakova & Kovalev (2015) presented an analysis of existing energy efficiency indicators (EEI) showing a discrepancy between the engineering concept of energy efficiency based on the thermodynamic definition and macroeconomic understanding of energy efficiency, the energy intensity. The authors suggest a new set of EEIs following a consistent hierarchy of parameters ( Figure 2) defining various levels, starting at a physical level and reaching the macro-economic level, although the industrial and macroeconomic levels were not described in more detail (Proskuryakova In forest biomass supply, the state-of-the-art forest technology and available forest machinery effects directly the physical and technological levels, while indirectly also the enterprise level and industrial level through the existing biomass supply chains.…”

This thesis summarises the findings of four case studies focussing on the redesign of specific aspects of the forest chip supply chain, the use of alternative terminals for chip supply, the interdependencies of chipper and chip trucks and the performance of individual machines after machine alteration. The aim of the work was to analyse and improve the fuel economy and energy efficiency of the forest chip supply system by modifying the settings of CTL harvesters, investigating the performance of an innovative hybrid chipper, introducing alternative supply systems through the use of a feed-in terminal and an analysis of forest chip supply systems under selected operational and environmental conditions. The analysis of the case studies involved individual machines and the entire forest chip supply system. Two study methods were used: work study and discrete event simulation (DES). Work study carried out to investigate the performance of individual machines and their alteration; the DES method was used for investigating the organisational redesign of the forest fuel supply system. The study resulted in the following findings and conclusions: 1) extreme machine settings have a statistically significant impact on the fuel economy of CTL harvesting machines; 2) hybrid machine technology can improve the fuel consumption and energy efficiency of chipping operations in forest chip production; nevertheless the productivity of the analysed prototype was below that for compared traditional chippers; 3) as an alternative to the direct supply of forest chips, the effect of utilising terminal operations on the overall supply cost can be quantified; terminal use improves the annual use of the supply fleet and enhances fuel supply security to the plant thereby reducing the need for supplementary fuel and 4) applying different types of types of chipper and truck-trailer combinations, supply costs and efficiencies can be quantified and vehicles with increased carrying capacity can improve the cost competitiveness. In the study an integrated approach taking physical, technological, enterprise and industrial levels of energy efficiency into account is proposed. Thereby state-of-the-art forest technology and current biomass supply ideally can be upgraded to achieve new, improved levels of performance and energy efficiency.

“…It is the trade-off between a slower, but the more efficient process, and its faster, but less efficient alternative. It is one of the functions of energy efficiency indicators to ease the analysis of such a trade-off [26]. There are a variety of effects related to data availability and data reliability which hamper the precision which energy efficiency indicator analyses of the manufacturing industry can achieve.…”

Energy and its ramifications make up a large part of the discussions in the agendas of various countries. Along with the energy resource, energy efficiency is also being reported in studies on ways to improve its use in industries. In the food industry, in particular, its use is intensive in its manufacturing processes, and thus the indicators that measure the use of this feature have become important. The paper uses the method of a systematic literature review to search for data related to the food industry and what are the energy efficiency indicators adopted in the processes. The objective of the research is to report which are the indicators of energy efficiency adopted in the food industry and the advances achieved with its adoption. The results indicate a broad field of research in this industry sector because the indicators used in measuring process efficiency are still poorly understood and adopted.

The strategic business firm manages today's profitability and tomorrow's sustainability to achieve a comparative advantage in the emerging market economy. Considering India's ambitious emission reduction target and rapid economic development, this study explores the potential relationship between corporate social responsibility (CSR) and the energy efficiency of manufacturing firms in India. Using firm‐level data, the panel fixed effects model shows that CSR negatively explains energy intensity (EI). We observed a consistent negative relationship between CSR and EI for all models, with and without controlled firm‐specific variables. Firms that manufacture chemical and chemical products, pharmaceuticals, medical chemicals and botanical products are energy intensive without CSR; however, CSR activities helped these firms become energy efficient. Our result confirms that voluntary CSR is less efficient than mandatory CSR in contributing to environmental and energy‐related indicators at the firm level. Our empirical results indicate several policy implications: (1) CSR should also focus on sustainable business models related to energy efficiency and reduction in carbon emissions; (2) firms should be encouraged to use CSR related to environmentally friendly innovations. We conclude that CSR spending and environmental expenses will increase energy efficiency at the firm level, which will help achieve net‐zero targets and sustainable industrial development.
