Achieving sustainable consumption of energy is an important issue due to the increasing demand for energy and its environmental impact. One of the biggest consumers of the global energy production is the residential sector. Factors determining pattern of energy consumption in this sector are firstly, characteristics of the buildings and equipment and appliances which are used inside them and secondly, people who are using the buildings. The former could be approached by using efficiency strategies; i.e. designing and using materials and utilities which are low energy demanding or reducing consumption of energy. The latter could be reached by adoption of demand side management strategies which could improve pattern of energy consumption by the end users. Combining these strategies bring out energy-smart buildings with energy-smart people as the users. This project aims at introducing potential approaches to strategies of promoting sustainable behavior regarding energy consumption in individuals, with the focus on the students of Linköping University living in the properties of housing company of the city, Studentbostäder. For fulfilling this purpose, literature review has been done for finding influencing factors on and strategies for shaping of pro-environmental behavior. In the next step, two projects with focus on demand side management for changing energy consumption of individuals have been studied. Afterward, a questionnaire based on the results of the literature review was prepared and used to gain an understanding of first: attitude, values, knowledge, and awareness of students of Linköping University regarding environmental issues, and second: point of view of the students toward the strategies for shaping pro-environmental behavior. Results of the above mentioned methods were used for identifying characteristics of a demand side management project based on provision of feedback on energy consumption for the users. It has been proposed that designing and implementing such project has the potential of affecting pattern of energy consumption by people and lead to its reduction, especially among students accommodating at housing company of city of Linköping, Studentbostäder. More studies are needed for finding feasibility of implementing such project.

The aim of this study is to compare the sustainable development perspective of Turkey with selected European Union countries in terms of Energy Indicators for Sustainable Energy between 1980-2008. The study is conducted in a comparative and descriptive way by using energy indicators. The common energy policy priorities of Turkey and European Union are determined in the light of recent literature. An energy indicator set is constructed according to energy priorities, namely, energy efficiency and energy intensity / energy security and fuel mix / and environmental concerns. The analysis of relevant indicators demonstrates that Turkey does not meet the sustainability criteria in terms of energy use. In general, findings of the study indicate that Turkey does not use energy efficiently and energy intensities in the economy do not decrease except for the industry sector, for the period 1980-2008. Import dependency has increased and fuel mix of energy sources is dominantly carbon based. Expectations about increasing renewable energy share do not exhibit a significant trend thus energy security and fuel mix are still important issues for Turkey. Lastly, environmental protection in terms of decreasing GHG emissions, air pollution and deforestation could not be achieved as GHG emissions, air pollution and deforestation have increased in Turkey during 1980- 2008 period.

<p>The risk for climate change is a growing concern for theglobal society. According to what is known as the Kyoto Protocol,developed countries have committed themselves to reduce theirgreenhouse gas (GHG) emissions. The purpose of this thesis hasbeen to analyse opportunities for CO2 reductions in Swedish pulpand paper mills. The pulp and paper industry accounts forsignificant shares of the Swedish utilisationof both electricityand, in particular, biomass fuels. In this thesis, it has been agoal to focus not only on the technical potential of alternativesfor CO2 reductions in the energy systems of pulp and paper mills,but also on analysing the costeffectiveness of the studiedmeasures. Moreover, the analysis has covered questions concerningthe capacity and willingness among the actors involved with thepulp and paper mills’energy systems to realise CO2reduction potentials.</p><p>A broad techno-economical evaluation of available technologiesfor increased power production as well as more efficient energyutilisation is carried out. Furthermore, a more indepth analysisof pulp mill-based biomass energy with CO2 removal and permanentsequestration (BECS) is presented. An evaluation is made of thepotential for pulp and paper production with a negative CO2balance through the implementation of BECS. In recent yearsoutside suppliers, mainly energy service companies (ESCOs), havebegun to operate energy facilities in some Swedish pulp and papermills. Based on interviews with managers from pulp and papercompanies and ESCOs, the main driving forces behind theincreasing co-operation as well as the opportunities and riskswith energy related co-operation are presented.</p><p>Furthermore, the technical possibility of carbon-negativitythrough the implementation of BECS is discussed in relation tocarbon management on both corporate and global levels. The extentto which CO2-reducing measures in pulp and paper mills arerealised will have an impact on Sweden’s capacity to reachCO2 reduction targets. Whether or not technologies for CO2capture and sequestration are developed and implemented inSwedish pulp mills has a very large impact on the size ofSweden’s long-term CO2 reduction potential. Moreover, thedevelopment of business and competence focus in pulp and papercompanies and ESCOs suggests that cooperation will become ofincreasing importance for future sustainable industrial energymanagement.</p><p><b>Keywords:</b>CO2 reduction, pulp and paper industry, energysystem, biomass, CO2 capture and sequestration, black liquor,gasification, power production, outsourcing, sustainable energymanagement</p>

Biomass-fuelled proton exchange membrane fuel cells (PEMFCs) offer asolution for replacing fossil fuel for hydrogen production. Through using thebiomass-derived hydrogen as fuel, PEMFCs may become an efficient andsustainable energy system for small and medium-sized enterprises. The aim ofthis thesis is to evaluate the performance and potential applications of biomassfuelledPEMFC systems which are designed to convert biomass to electricity andheat. Biomass-fuelled PEMFC systems are simulated by Aspen plus based ondata collected from experiments and literature.The impact of the quality of the hydrogen-rich gas, anode stoichiometry, CH4content in the biogas and CH4 conversion rate on the performance of the PEMFCis investigated. Also, pinch technology is used to optimize the heat exchangernetwork to improve the power generation and thermal efficiency.For liquid and solid biomass, anaerobic digestion (AD) and gasification (GF),respectively, are relatively viable and developed conversion technologies. ForAD-PEMFC, a steam reformer is also needed to convert biogas to hydrogen-richgas. For 100 kWe generation, the GF-PEMFC system yields a good technicalperformance with 20 % electrical efficiency and 57 % thermal efficiency,whereas the AD-PEMFC system only has 9 % electrical efficiency and 13 %thermal efficiency. This low efficiency is due to the low efficiency of theanaerobic digester (AD) and the high internal heat consumption of the AD andthe steam reformer (SR). For the environmental aspects, the GF-PEMFC systemhas a high CO2 emissions offset factor and the AD-PEMFC system has anefficient land-use.The applications of the biomass-fuelled PEMFC systems are investigated on adairy farm and an olive oil plant. For the dairy farm, manure is used as feedstockto generate biogas through anaerobic digestion. A PEMFC qualified for 40 %electrical efficiency may generate 360 MWh electricity and 680 MWh heat peryear to make a dairy farm with 300 milked cows self-sufficient in a sustainableway. A PEMFC-CHP system designed for an olive oil plant generating annual 50000 m3 solid olive mill waste (SOMW) and 9 000 m3 olive mill waste water(OMW) is simulated based on experimental data from the Biogas2PEM-FCproject1. After the optimization of the heat exchanger network, the PEMFC-CHP  system can generate 194 kW electricity which corresponds to 62 % of the totalelectricity demand of the olive oil plant.The economic performance of the PEMFC and biogas-fuelled PEMFC areassessed roughly including capital, operation &amp; maintenance (O&amp;M) costs of thebiogas plant and the PEMFC-CHP, the cost of heat and electricity, and the valueof the digestate as fertilizer. / <p>QC 20151109</p>

Automotive industry is facing fundamental challenges due to the rapid depletion of fossil fuels, energy saving and environmental concerns. The need of sustainable energy development has motivated the research of energy reduction and renewable energy sources. Efficient use of energy in vehicle manufacturing is demanded, as well as an alternative energy source to replace gasoline powered engines. In this thesis, we introduce a case study at an automotive paint shop, where the largest amount of energy consumption of an automotive assembly plant takes place. Additionally, we present a summary of recent advances in the area of hybrid and electrical vehicles battery manufacturing, review commonly used battery technologies, their manufacturing processes, and related recycling and environmental issues. Our study shows that energy consumption in paint shops can be reduced substantially by selecting the appropriate repair capacity, reducing the number of repainted jobs and consuming less material and energy. Also, it is seen that considerable effort needs to be devoted to the development of batteries for hybrid and electric vehicles in the near future, which will make this area challenging and research opportunities promising.

Governments and policy-makers are currently dealing with some key issues as energy security in countries dependent on oil imports; global economic development, including increased food production; and controlling global climate change and greenhouse gas emissions. The perception that biofuel could solve these challenges simultaneously has led to the implementation of policy and regulatory mechanisms on the mandatory use of biofuels, resulting in a sharp increase in biofuel production and consumption. Serious concerns about large-scale ethanol production have been raised regarding loss of biodiversity and competition for land between food and ethanol production. It is also suggested that sugarcane-based ethanol increases GHG emissions due to indirect land use change. Furthermore, sugarcane harvesting has been criticised for causing air pollution and bad working conditions for cutters. These criticisms have mostly been denied by Brazilian actors. This thesis seeks to clarify these divergent views and conflicts concerning Brazilian ethanol. It was carried out within a KTH research programme that uses frames in the analysis of conflicts emerging from the development and implementation of new technologies. Frame analysis can help improve understanding of such conflicts, which derive from differences in values, world views and beliefs and can be difficult to resolve. Frame analysis seeks to identify the particular factors determining the actions taken by different stakeholders, giving equal treatment to all actors. The results showed that the international views expressed in the media captured the attention of the public and policy-makers, and led them to frame ethanol as a destructive for nature fuel. The analysis identified that the ethanol as a threat to food security frame combined with the ethanol as a destructive for nature frame led the public and policy-makers to frame ethanol as a brown fuel. However, Brazilian actors frame ethanol differently: as a green and safe fuel. These differences have raised the conflicts that are analysed in this thesis. Furthermore, the analysis identified that the changes in the harvesting system, from manual to mechanised –besides decreasing air pollution- will cost the job of hundreds of thousands of cane cutters. Values and beliefs orientating such changes are analysed in the thesis. / QC 20110912

National access to modern energy is deemed by Malawi government as the driving force to attain social-economic development. To achieve this, optimal decisions in energy planning and investment are considered important. This study evaluates potential pathways that will inform better policy design and investment option in energy sector. The Integrated Assessment Modelling method has been used to integrate social, economic and environmental variables that affect energy systems, and further analyses potential energy pathways in relation to these earth systems. The Long-range Alternatives Energy Planning system (LEAP) has been used to run a continuous time series from 2008 to 2063 of the three energy policy pathways (scenarios) using: (1) the current Malawi National Policy and Strategies on Energy (MwNEP) (2) the United Nation’s Sustainable Energy for All strategy (SE4ALL) and (3) Business as Usual (REF) scenario. The analysis indicates an exponential growth in energy demand for both MwNEP and SE4ALL scenario with a slight higher demand in SEAll over MwNEP Scenario. In both cases Biomass remains an important energy source beyond the 2030. Thus, the SDG 7 will not be achieved by 2030. Similarly, energy demand trends in MwNEP and SE4ALL scenarios continue to grow beyond available energy stocks and generation capacity which will lead to a shortfall in energy supply. Environmentally, the GHGs emissions in MwNEP are higher than the SE4ALL scenario. This is reflected in the pro-environment policy objective pursued by SE4ALL scenario. In the medium-term LEAP analysis favours advancement of alternative renewable energies at household level like solar photovoltaic (PV) for lighting and sustainable biomass energy for cooking. In the long-run, scaling up the adoption of renewable energy in form of solar, wind and hydro-electricity to meet the energy gap. At the same time, designing and adhering to implementation of sustainable energy plans that cuts energy sources from fossil fuels and allow easy accesses to affordable renewable energies will result in a success of Malawi’s energy system.

Thus, the regulation of the energy sector should consider one trilemma involving low costs, energy security (continuity and independence) and environmental preservation. In this line, this study aims to determine the level of regulatory importance of the principle of environmental protection established in the constitutional chapter of economic order, through the Program of Incentives for Alternative Electricity Energy Sources (PROINFA), for this it was studied most theories of regulation and the economics tools used in the international arena to stimulate alternative energy sources. To facilitate a strategic analysis, game theory has been used to integrate international and domestic relations in regulating the electricity sector. Thus, it was concluded that the Brazilian regulatory model does not prioritize environmental preservation, but it is a good choice to solve the games of energy, stimulating a sustainable energy matrix. / O padrão de vida da sociedade moderna exige um contínuo aumento do uso de energia, seja para a esfera da produção ou do consumo, tendo um grande impacto no meio ambiente devido à poluição gerada pela produção energética. Desta forma, a regulação do setor energético deve ponderar um trilema que envolve o baixo custo da energia, a segurança energética (continuidade e independência) e preservação ambiental. Nesta linha, o presente estudo objetiva averiguar o nível de importância regulatória do princípio da preservação ambiental disposto no capítulo constitucional da ordem econômica, através do Programa de Incentivo às Fontes Alternativas de Energia Elétrica (PROINFA), para isto, foram abordadas as teorias da regulação e as ferramentas econômicas utilizadas no cenário internacional para estimular fontes alternativas de energia. Para facilitar a análise estratégica, foi utilizada a teoria dos jogos para integrar as relações internacionais e do mercado interno na regulação do setor elétrico. Desta forma, concluiu-se que o modelo regulatório brasileiro não prioriza a preservação ambiental, mas é uma boa escolha para resolver os jogos de energia, estimulando uma matriz energética sustentável.

Human misuse of environmental assets especially energy is causing environmental degradation, which hampers social and economic welfare for present as well as for future generations. A worldwide shift to sustainable energy sources is one of the required actions to solve the problem. Electricity from sustainable energy sources is called green electricity and has arose as one of the most motivating tools for developing the sustainable energy market. This has resulted in the restructuring of Germany&apos;s energy industry with a dramatic change in energy use in electricity. The change has been aided by the German renewable energies act (EEG), which is been criticized for its resulting high green electricity prices which consumers have to pay. Green electricity prices seem to call for more consumers&apos; attention than threats posed by conventional energy because only a small fraction of energy is sold as green electricity neccesitating the rethinking of the energy market. Due to the need for future research on more factors influencing consumers buying behavior in the green electricity market, this thesis seeks to investigate the following research questions: Is green electricity price the major influencing factor for its market unattractivess? Does the concern about price really calls for more attention than environmental concerns? It specifically aims to describe German consumers&apos; perceptions of factors influencing their green electricity buying behavior. The research methodology involves the use of secondary and primary data. The secondary data gives a background knowledge of Germany and its energy historical development, Germany&apos;s sustainable energy strategies and strategies for market development (electricity feed-in-tariffs, the renewable energy act and problems), green electricity marketing, consumers&apos; purchasing behavior and factors influencing this behavior. The primary data is gotten through a questionnare survey and analysed using both excel and the statistical package for social sciences. Evidence is taken from Germany because of its ambitious goals of 20-30% green electricity by 2020 and 80-100% by 2050. The result of the study shows that, although price is the most influencing factor in choosing an electricity supplier and also calls for more attention than environmental concerns, it&apos;s not the major hindering factor for the green electricity market unattractivess. Most German electricity consumers (42%) have no idea about green electricity prices. In comparison to competitors, 27% of them assume the prices are higher while 31% say the prices are thesame and even lower. All green electricity consumers confirm the prices are moderate and even cheaper. Even when prices are the same, most respondents gave other reasons like conviniences before environmental friendliness as the first motive for their electricity choice. Despite Germany&apos;s ambitous goals, consumers selfinterest and ignorance about green electricity prices remain a problem for the market.
