Sweden aims to become one of the first fossil-free welfare countries in the world. In 2009, specific energy and climate policy targets were announced for 2020, which exceed the ambition of respective EU targets in some areas. The overarching objective of the thesis is to understand the role of energy efficiency in Swedish energy and climate policy frameworks, and identify the gaps that need to be addressed. In this context, energy efficiency is recognized as a challenge to address. Yet, there are reasons to believe that it is not being pursued with the same dedication as other energy and climate-related targets. This hypothesis is tested using Mixed Methods research, with cases on different sectors of the Swedish economy, namely energy intensive industry and public bus transport, as well as comparisons with energy efficiency within the EU-28. With the help of abductive reasoning, the observations are inferred to an explanation, and common themes for Swedish energy efficiency policies emerge. The evidence indicates that energy efficiency has received lower priority than other energy and climate policies. This is demonstrated by the conflict between energy efficiency, emission reduction and renewable energy targets, for example in the case of public transport. There is generally a mismatch between targets and the instruments in place. Thus more attention should be given to energy efficiency and its potential benefits for the Swedish energy system. Opportunities for energy efficiency improvements are not being fully realized, but new policy initiatives could provide the necessary support to harness the potential. In-depth evaluation of new policy instruments should be integrated in the policy-making process, in order to provide a clear picture of costs versus benefits. An example is given with a Cost-Benefit Analysis for energy efficiency obligations targeting the Swedish energy intensive industry. Simplicity and transparency in the introduction and monitoring of new instruments need to be sought for. Energy efficiency should be given first priority in relation to other energy and climate targets. The basis for future policies should be grounded now in order for energy efficiency to become the key for successful Swedish energy policy. / <p>QC 20160914</p>

Life Cycle Assessment (LCA) is a widely used method for evaluating the environmental impacts of a product throughout its entire life cycle. As a decision-making tool, LCA allows decision-makers to identify the environmental hotspots in a product or process, and to explore opportunities for improvement. However, while LCA has many potentials, it also has several limitations that need to be considered. One of the main limitations of LCA is the difficulty in obtaining accurate data, particularly for the upstream and downstream stages of a product's life cycle. Another limitation is the challenge of interpreting the results, as LCA involves complex calculations and assumptions that can be difficult for non-experts to understand. Despite these limitations, LCA remains a valuable tool for informing decision-making, and efforts are being made to address these limitations through the development of standardized methods and improved data collection and interpretation techniques. This paper provides an overview of LCA as a decision-making tool in the context of vaccine manufacturing, its potential and limitations, and the current state of research in this field.

To make a difference among the energy intensive process industries, this dissertation addresses production planning and supply chain planning problems related to industrial energy management issues. The energy issue is turning more and more important from different angles, involving price as well as environmental problems due to climate change leading to political pressure on all energy users. The process industry sector is one of the largest users of energy, and thus important to analyse. Process industries are also capital intensive and operate on large and expensive process equipment, making it imperative to plan their production well in order to reach preferable capacity utilisation. Therefore this dissertation strives to locate the most important energy management issues for the long term profitability of process industries, and investigates the  symbiotic effects of including energy issues in production and supply chain planning. Three different studies at three case companies are carried out, analysed, and presented in five papers. The cases represent the process industry sectors: chemicals, pulp, and steel. Both qualitative case study methodologies as well as quantitative mathematical modelling and optimisation approaches have been practiced. The research questions are analysed from both an energy system and from a production process point of view, separately as well as combined. Energy is somewhat considered to be the main workforce for process industries and this dissertation exemplifies some of its most important dimensions in this context. Several prerequisites for putting energy management on the strategic agenda are located in a specialty chemical industry where the importance of introducing a strategic perspective on energy, the way energy is used, and the possibilities of increasing alternative revenue from utilising by- and/or co-products differently are pinpointed. Approaches for including energy issues in planning processes are also suggested in terms of a MILP model for the entire supply chain of a pulp company, including decisions on purchase and transportation of raw maerials, production allocation, energy mix, and distribution. Another example is presented based on the perspectives of economics of scale and lot sizing through economic order quantity principles in a steel company. By using real company data, energy smart approaches in planning and scheduling are developed with respect to the most important intersections between the production processes and their supporting energy system. The accumulated resource intensity and embedded energy could, and probably should, hence be more fairly  reflected in the product price. The research finally shows some possible impact with including energy issues in a production and supply chain planning model. By planning differently, production prioritisations can be done, and it is not only possible without any large investments, but also prosperous with savings on both energy and money within reach. To conclude, planning of production and supply chain has either a direct or an indirect impact on the energy cost-effectiveness of a company. This dissertation argues that such impact also exists in its mutual form, and is very important when the energy issues are large enough, as they often are in the energy intensive process industry sector. Decision makers should thus beware of the short end of the stick that might be  devastating in the long run, but also aware of all the possibilities that can bring success and prosperity when the future begins.

L'augmentation des prix de l'énergie due à la raréfaction des énergies fossiles et la prise en compte des impacts environnementaux rend inéluctable l'engagement des industriels dans une démarche de maitrise de leurs consommations énergétiques et leurs émissions. L'Industrie Diffuse (ID), par opposition aux IGCE, est de plus en plus importante sur le plan économique, énergétique et environnemental. Elle devient ainsi une cible prioritaire d'autant plus que l'on constate qu'elle a été peu traitée dans les analyses énergétiques malgré l'intérêt des politiques en matière d'efficacité énergétique et le nombre considérable d'articles et de livres sur l'énergie. Comment quantifier alors l'implication de l'ID dans la contrainte réglementaire liée au changement climatique ? Quelles technologies et politiques à mettre en œuvre pour contribuer aux objectifs fixés par les plans d'actions pour l'efficacité énergétique ?Le travail de cette thèse repose ainsi sur une optimisation technico-économique de la chaine énergétique, à partir du modèle « bottom-up » de TIMES, dans une approche prospective pertinente des conséquences énergétique et environnementale de politiques MDE dans l'ID. Ce modèle s'appuie notamment sur une représentation par usages à l'inverse des IGCE du fait de l'inadaptabilité de l'approche produit/procédé. Dans ce cadre, l'analyse de la valorisation de la chaleur perdue en sortie des procédés à travers le déploiement de PAC dans l'agroalimentaire a été réalisée.Le recours à la modélisation prospective permet notamment d'observer le profil technologique et le timing des investissements des PAC en réponse à des contraintes énergétiques ou de mesures incitatives dans le cadre de Certificat d'Économie d'Énergie ou de valorisation des émissions de CO2. Il peut mettre aussi en lumière, d'une part, une possibilité d'étude sur un ajustement incrémentiel d'une taxe sur les émissions par les autorités de régulation pour atteindre leurs objectifs environnemental et énergétique sur le court, moyen et long-terme. D'autre part, il constitue un bon outil d'aide à la décision en déterminant des coûts différenciés d'économies d'énergie dans le cadre d'investissements de technologies MDE pour un meilleur criblage sectoriel. / The growing energy prices due to the rarefaction of the fossil fuels and the consideration of the environmental impacts makes inevitable the involvement of industrials to promote energy efficiency policy and emissions reductions. We notice that the Non-energy intensive industry (NEI), by opposition to the energy intensive industry (EI), is expected to play an important role because of their economic and energy importance and its relatively high growth rate. It becomes then a priority target especially since it has been neglected in energy analysis despite the continuing policy interest in energy efficiency and the many reports and book written on the topic. How can NEI contribute effectively to the reduction of the energy consumptions and the CO2 emissions? Which technologies and/or policies should be implemented to reach these objectives?This PhD work is then based on a technical economic optimization of the sectoral energy system, by using a “bottom-up” model with TIMES framework, in a relevant prospective approach of the energy and environmental consequences of MDE policies in NEI. This model relies on a representation by energy end-uses contrary to the EI because of the unsuitability of the approach product/process. As part of this, we analyzed the industrial heat recovery on processes through the deployment of HP in Food & Drink industry, the most important NEI's sector.Then, this prospective modelling allows observing the shape of investments of HP in response to energy constraints or incentive policies within the mechanism of Energy Savings Certificate or valuation of CO2 emissions. It can give, on one hand, a possibility of study which giving the different adjustment of a tax on gas emissions by the authorities of regulation to reach their environmental and energy objectives in NEI over a medium or long-term horizon. On the other hand, it is very useful as a good decision-making tool by determining differentiated costs for energy savings within the investments of efficient technologies at the highest level of disaggregation for a better sectoral screening

Cette thèse vise à analyser les enjeux et les conséquences la consommation énergétique dans les pays anciennement communistes d’Europe et d’Asie Centrale (EAC). Plus particulièrement, nous soulevons la question des politiques économiques à mettre en place afin d’améliorer l’efficacité énergétique dans cette région et analysons les conséquences en termes de pollution et de croissance de la spécialisation intensive en énergie de leurs économies.Le système d’économie planifié a profondément altéré les structures économiques et la trajectoire de consommation énergétique de ces pays. En effet, une des empreintes restantes de l’économie de type soviétique réside dans l’importante intensité énergétique et la forte spécialisation des pays EAC dans les industries intensives en énergie. Les récentes crises géopolitiques vis-à-vis de la Russie, l’épuisement des ressources énergétiques fossiles ainsi que la problématique environnementale mettent en exergue l’importance de la question énergétique dans ces pays.La présente thèse s’intéresse plus spécifiquement à deux problèmes fondamentaux. Comment améliorer les performances énergétiques des pays Est-Européens ? Et quel est l’impact de la spécialisation dans les industries structurellement intensives en énergie sur la croissance des pays EAC ?Dans le premier chapitre, nous analysons les fondations microéconomiques de la demande énergétique en se focalisant sur les déficiences de marché qui peuvent contraindre l’efficacité énergétique des firmes. Nous nous intéressons en particulier à l’effet relié au développement financier. L’inefficience des marchés financiers est une des principales explications du « paradoxe d’efficience énergétique », mais n’a pour l’instant pas été empiriquement démontré. Les résultats empiriques de ce chapitre montrent que les marchés financiers locaux jouent un rôle important dans la consommation énergétique des firmes.Le chapitre 2 examine dans quelle mesure la réglementation environnementale de l’Union Européenne (UE) impacte la spécialisation des pays est-européens dans les industries polluantes. En ce sens, ce chapitre traite de la question centrale du développement de havres de pollution en Europe de l’Est. Nos résultats indiquent que les exportations des pays EAC vers un pays de l’UE sont relativement plus importantes dans des secteurs polluants lorsque ce pays a dû mettre en place des mesures environnementales. Cet effet est rendu robuste au biais de variables omises grâce à l’inclusion d’un ensemble d’effets fixes. De plus, le problème potentiel de causalité inverse est traité grâce à l’utilisation d’un instrument exogène de politique environnementale basé sur les conditions climatiques des pays.Au-delà des problèmes liés à l’environnement, le chapitre 3 analyse les conséquences économiques de la spécialisation dans des industries énergivores dans la région EAC. En effet, cette spécialisation est un héritage direct de l’ancien système d’économie planifiée. L’économie planifiée de type soviétique a façonné une spécialisation dans des secteurs industriels très énergivores, et ce indépendamment des caractéristiques structurelles spécifiques des différents pays de l’ancien bloc de l’Est. La volonté idéologique et les distorsions de marché dans ces économies ont été les principaux moteurs d’un surdéveloppement des industries extrêmement énergivores. L’effet de la sur-spécialisation dans les industries intensives en énergie est strictement négatif et significatif dans toutes nos estimations. Ce résultat est robuste et met en exergue des symptômes de « maladie soviétique ». Les pays anciennement communistes qui maintiennent des distorsions de spécialisation dans les secteurs industriels développés sous le système d’économie planifiée font face à de moins bonnes performances économiques. Ainsi, maintenir une spécialisation industrielle intensive en énergie est inefficace aussi bien d’un point de vue environnemental que d’un point de vue économique. / The current thesis raises important issues about the drivers able to improve energy intensity of the Eastern Europe and Central Asia (ECA) region from both an efficiency point of view and in terms of structural specialization in energy-intensive sectors. In particular, we question about the rationale of keeping a high degree of specialization in energy-intensive sectors, given that this specialization was primarily based on the mechanisms of the former planned economy system. This dissertation consists of three empirical essays studying these issues.We focus on two main questions. How to improve energy and pollution performances of the ECA countries? And how the over-specialization in energy-intensive sectors affects their economic growth? The first question is examined in Chapters 1 and 2, whereas the second question is discussed in Chapter 3.To address these issues there is a need to analyze the two components of the energy intensity, namely the energy efficiency and the structural specialization in energy intensive sectors, with the adequate levels of investigation. To cover the scope of the different problems raised by the legacy of high energy intensity in the ECA countries, I thus rely on micro-, sector- and macro-level analysis. Chapter 1 considers the market constraints to firm-level energy efficiency and examines whether the financial development explains the firm-level energy efficiency. Then, using bilateral export flows at the industry-level, Chapter 2 studies how environmental policy inside the EU influences the energy- and pollution- intensive specialization in ECA countries that are not EU members. More specifically, this chapter aims to exhibit to what extent the EU environmental stringency fosters the pollution havens in the ECA region by stimulating exports in energy-intensive sectors. And finally, Chapter 3 seeks to provide macroeconomic evidence about the growth consequences of the maintaining of a specialization highly oriented towards energy-intensive sectors. This ultimate chapter tries to identify whether over-specialization in energy-intensive sectors is negative for growth performances in this region.

About a third of the energy in Sweden is used for production in industry, where a few energy-intensive industries account for a large proportion of the energy use. When energy efficiency takes place here, the positive environmental effects will be substantial. Therefore, there is often great potential to reduce energy use in these industries. The purpose of this study is to investigate the company's energy use in order to be able to present proposals for cost-effective improvement measures that lead to a reduction in the company's energy consumption, which in turn leads to a reduced environmental impact. The study has used sustainable development, total quality management and Kotter’s 8-step process for leading change as a theoretical background. The study is a qualitative and quantitative case study and the data collection was done using semi-structured and unstructured interviews, observations and document analysis. The study’s results show that the company uses unnecessary energy in three energy consumption areas: compressed air, heating and electricity. To reduce energy use, the company needs to put in place a shut-down management, appoint an energy coordinator, prioritize preventive work, repair broken equipment and introduce preventive maintenance, optimize the ovens, involve employees in continuous improvement and to have a committed leadership. By reducing energy consumption, the company can reduce its impact on the environment, and by implementing the improvement measures, the company can save several million SEK each year. / Ungefär en tredjedel av energin i Sverige används för produktion inom industrin, där ett fåtal energiintensiva branscher står för en stor andel av industrins energianvändning. När energieffektivisering sker här blir de positiva miljöeffekterna stora. Därför finns det ofta stor potential att minska energianvändningen i dessa branscher. Syftet med denna studie är att undersöka företagets energianvändning för att sedan kunna presentera förslag på kostnadseffektiva förbättringsåtgärder som leder till en minskning av företagets energiförbrukning, vilket i sin tur leder till en minskad miljöpåverkan. Studien har använt sig av hållbar utveckling, hörnstensmodellen och Kotters 8-stegsmodell för förändringsledning som teoretisk bakgrund. Studien är en kvalitativ och kvantitativ fallstudie och datainsamlingen gjordes med hjälp av semistrukturerade och ostrukturerade intervjuer, observationer och dokumentstudier. Studiens resultat visar på att företaget använder energi i onödan inom tre energiförbrukningsområden: tryckluft, värme och el. För att minska energianvändningen behöver företaget införa avstängningsrutiner, utse en energikoordinator, prioritera förebyggande arbete, reparera trasig utrustning och införa förebyggande underhåll, optimera ugnarna, involvera medarbetarna i förbättringsarbetet och ha ett engagerat och delaktigt ledarskap. Genom att minska energiförbrukningen kan företaget minska sin påverkan på miljön och genom att implementera förbättringsåtgärder kan företaget spara flera miljoner kronor varje år.

Studien undersöker hur Porjus vattenkraftverk påverkade den industriella utvecklingen i Norrbottens län mellan 1915–1938. Syftet med uppsatsen var att undersöka om elintensiva industrier etablerades efter vattenkraftverkets invigning samt hur industristrukturen i Norrbottens län påverkades under perioden 1915–1938. För att svara på frågorna blev undersökningen en fallstudie som utredde hur och om elektriciteten från Porjus vattenkraftverk bidrog till ekonomisk utveckling i Norrbottens län. Att utvecklingen av elektricitet och elinfrastruktur ska gynna den ekonomiska utvecklingen genom en ökad etableringstakt av industrier samt att industrierna blir mer elintensiva har visats i tidigare forskning. Samtidigt som andra studier demonstrerat hur elektrifiering inte nödvändigtvis leder till ekonomisk utveckling om inte priserna är lönsamma. Slutsatsen av undersökningen är att Porjus vattenkraftverk gav upphov till ökad industrietablering i Norrbottens län, där de elintensiva industrigrupperna gynnades till störst del. Slutligen drogs slutsatsen att industristrukturen i Norrbotten primärt stärktes snarare än ändrades efter att vattenkraftverket invigdes år 1915. / This thesis analyzes how Porjus hydropower plant affected the industrial development in Norrbotten county between 1915-1938. The purpose of the study was to investigate if electricity-intensive industries arose after the inauguration of the hydropower plant, and how the industrial structure in Norrbotten county was influenced during the period 1915-1938. To answer those questions a case study was performed to investigate if and/or how the electricity from Porjus hydropower plant contributed to economic development in Norrbotten county. Previous studies have shown that the development of electricity and electricity infrastructures will benefit economic development through an increased number of industries and that the industries will become more electricity-intensive. At the same time, other studies have demonstrated how electrification does not necessarily lead to economic development unless prices are profitable. The conclusion of the thesis is that an increase of industrial establishments in Norrbotten county appeared after the inauguration of Porjus hydropower plant. At the same time the electricity-intensive industrial groups where the ones that benefited the most from the increased electricity the hydropower plant generated. Finally, it was concluded that the industrial structure in Norrbotten primarily was strengthened rather than changed after the hydropower plant was inaugurated in 1915.

S tím, jak se neustále vyvíjejí nové technologie pro energeticky náročná průmyslová odvětví, stávající zařízení postupně zaostávají v efektivitě a produktivitě. Tvrdá konkurence na trhu a legislativa v oblasti životního prostředí nutí tato tradiční zařízení k ukončení provozu a k odstavení. Zlepšování procesu a projekty modernizace jsou zásadní v udržování provozních výkonů těchto zařízení. Současné přístupy pro zlepšování procesů jsou hlavně: integrace procesů, optimalizace procesů a intenzifikace procesů. Obecně se v těchto oblastech využívá matematické optimalizace, zkušeností řešitele a provozní heuristiky. Tyto přístupy slouží jako základ pro zlepšování procesů. Avšak, jejich výkon lze dále zlepšit pomocí moderní výpočtové inteligence. Účelem této práce je tudíž aplikace pokročilých technik umělé inteligence a strojového učení za účelem zlepšování procesů v energeticky náročných průmyslových procesech. V této práci je využit přístup, který řeší tento problém simulací průmyslových systémů a přispívá následujícím: (i)Aplikace techniky strojového učení, která zahrnuje jednorázové učení a neuro-evoluci pro modelování a optimalizaci jednotlivých jednotek na základě dat. (ii) Aplikace redukce dimenze (např. Analýza hlavních komponent, autoendkodér) pro vícekriteriální optimalizaci procesu s více jednotkami. (iii) Návrh nového nástroje pro analýzu problematických částí systému za účelem jejich odstranění (bottleneck tree analysis – BOTA). Bylo také navrženo rozšíření nástroje, které umožňuje řešit vícerozměrné problémy pomocí přístupu založeného na datech. (iv) Prokázání účinnosti simulací Monte-Carlo, neuronové sítě a rozhodovacích stromů pro rozhodování při integraci nové technologie procesu do stávajících procesů. (v) Porovnání techniky HTM (Hierarchical Temporal Memory) a duální optimalizace s několika prediktivními nástroji pro podporu managementu provozu v reálném čase. (vi) Implementace umělé neuronové sítě v rámci rozhraní pro konvenční procesní graf (P-graf). (vii) Zdůraznění budoucnosti umělé inteligence a procesního inženýrství v biosystémech prostřednictvím komerčně založeného paradigmatu multi-omics.
