Abstract [en]

Manufacturing industry has a large energy efficiency potential, yet to be utilized, known as the energy efficiency gap. This gap exists due to barriers that hinder industrial companies from making energy efficiency investments. Research also shows that the gap is even larger if energy management practices are included as well. One type of energy management practice for industrial companies is energy performance benchmarking, which deals with several organisational applications. For example, energy performance benchmarking can be used to compare a company’s degree of energy efficiency to its peers. A benchmarking approach can also be adopted on different levels of aggregation, including sector, site, and process level. Furthermore, continuous work with energy management also entails additional benefits beyond the energy effects, known as non-energy benefits. In an energy management context, these benefits might for instance be organisational or informational in nature. The aim of this paper is to study these aspects of energy management – benchmarking and non-energy benefits – within the Swedish pulp and paper industry.

These aspects of energy management have not, to the authors’ knowledge, been extensively investigated. The adopted method for data collection is a mixed method approach, where a questionnaire was sent to all operating pulp and paper mills in Sweden, and semi-structured interviews were carried out at six mills. The findings in this study show that the most common benchmarking method in the Swedish pulp and paper mills is external benchmarking within a company group. The benchmarking method with the highest perceived value for a mill’s energy management, however, is historical benchmarking of energy use. Furthermore, the pulp and paper mills have perceived a number of non-energy benefits from energy management practices, where top management’s interest in energy efficiency issues increasing more than expected was perceived as the most substantial.

Abstract [en]

Climate and environmental targets place significant requirements on energy efficiency and improved industrial energy efficiency is viewed as one of the most important means of reducing CO2 emissions and mitigating climate change. Even though efforts have been undertaken to improve energy efficiency there is still the potential for further improvements to be made. The potential is a result of that proposed energy efficiency improvement measures are not implemented, even if judged as cost-effective.

Besides improving energy efficiency, the implementation of energy efficiency improvements in industrial firms can generate additional beneficial effects: so-called non-energy benefits. Examples of non-energy benefits are: improved productivity, lower operation and maintenance costs, a better work environment, decreased waste and fewer external effects, such as lower emissions. This thesis has investigated the roles and potential of non-energy benefits in decisions on energy efficiency improvements from three perspectives: energy efficiency measures, energy efficiency investments and energy management activities.

The results of the studies presented in this thesis demonstrated that different types of non-energy benefits were observed in various areas within industrial firms due to the energy efficiency measures, energy efficiency investments and energy management activities they have implemented. Studying energy efficiency measures and investments revealed that implementing one single energy efficiency measure or investment can generate several non-energy benefits. The studies also uncovered a relationship between the non-energy benefits, i.e. chain reactions of primary, secondary and further effects, in which one benefit can generate other types of benefits. Consequently, some non-energy benefits were observed immediately after the implementation of energy efficiency measures, direct effects, while others were perceived later on, indirect effects. Furthermore, extending the perspective by including energy management activities led to the recognition of novel non-energy benefits.

The results of this thesis demonstrated that non-energy benefits were seldom acknowledged in decisions on energy efficiency improvements. However, the non-energy benefits’ character, diversity and relations among them enabled opportunities for the non-energy benefits to be included in decisions on energy efficiency in various ways. For instance, based on the results of these studies, monetised non-energy benefits could be included in investment calculations contributing to cost-effectiveness, while certain effects that are difficult to measure and quantify could be utilised qualitatively in investment evaluations as extra arguments, or, if important to the firm, as objectives for making the investment. Hence, depending on their type, non-energy benefits seemed to have different roles in decisions on industrial energy efficiency improvements.

This thesis contributed with a comprehensive approach by investigating energy efficiency improvements and the related non-energy benefits through three perspectives. By combining the results from each perspective, the view on industrial firms’ decisions on energy efficiency improvements was widened. In this thesis it is concluded that the potential of non-energy benefits in decision-making on industrial energy efficiency improvements lies in the utilisation of all types of non-energy benefits and to consider all the roles that non-energy benefits may have. By utilising knowledge on non-energy benefits along with their roles observed in relation to previous implementations of energy efficiency improvements, non-energy benefits can impact decisions on new implementations.

Abstract [sv]

Effektivisering av industrins energianvändning ses som ett av de viktigaste redskapen för att minska koldioxidutsläppen i syfte att mildra klimatpåverkan och nå uppsatta klimat- och miljömål. Konkurrens och resursbrist driver industrin till att effektivisera och kopplingen mellan energi och tillverkningsprocesser i företagen betyder att energieffektivisering är av vikt då den även bidrar till effektivisering generellt inom företaget. Trots detta genomförs inte alla föreslagna åtgärder även om de är kostnadseffektiva, vilket gör att det finns en potential till ytterligare industriell energieffektivisering.

Förutom energibesparing och energikostnadsbesparing kan implementering av energieffektiviserande åtgärder även ge ytterligare positiva effekter för företaget, så kallade mervärden (eng. non-energy benefits), exempelvis i form av ökad produktivitet, ökad livslängd för maskiner och utrustning, förbättrad arbetsmiljö samt minskad mängd utsläpp och avfall. Denna avhandling har studerat mervärdens roller och potential i beslut kring energieffektiviserande åtgärder och investeringar samt energiledningsaktiviteter.

Resultaten visade att implementering av energieffektiviserande åtgärder och investeringar samt energiledningsaktiviteter gav flera olika typer av mervärden observerade på olika nivåer och inom olika delar av verksamheten i industriföretag. Genom att studera mervärden ur flera perspektiv synliggjordes nya typer av mervärden samt att implementering av en enstaka energieffektiviserande åtgärd kan generera ett flertal mervärden av olika typ. Vidare sågs även samband mellan olika mervärden, dvs att ett mervärde gav upphov till ett flertal andra mervärden.

Resultaten av dessa studier visade att användningen av mervärden vid beslut kring energieffektivisering begränsas av att många mervärden är svåra att mäta och kvantifiera. Trots att många mervärden var svåra att värdera i pengar och inkludera i investeringskalkyler, visade resultaten att mervärden ibland användes kvalitativt i investeringsunderlag som extra argument. Om mervärdet var av stor vikt kunde det till och med anses vara del utav syftet med en energieffektiviserande investering. Detta visade på mervärdens olika roller beroende på deras karaktär samt hur viktiga de ansågs vara för företaget.

Denna avhandling har studerat energieffektiviseringar och relaterade mervärden ur tre perspektiv. Genom att kombinera resultaten från varje perspektiv erhölls en bredare syn på beslut kring energieffektivisering. Resultaten i denna avhandling visade att mervärden kan bidra på olika sätt i beslut kring energieffektiviseringar beroende på deras olika roller samt att mervärdens potential i sådana beslut beror på om och hur mervärdens olika roller beaktas och används. Genom att använda kunskap om mervärden och deras olika roller som observerats i samband med tidigare energieffektiviserande implementeringar, kan mervärden bidra till att påverka beslut vid planering av nya energieffektiviserande implementeringar.
