When it comes to climate change, one of the most pressing challenges is energy production and consumption in society, from individuals to markets. From economic incentives, path dependence and risk perceptions of our society, actions and strategise need to become more adaptable towards change. The actions and strategise need to be impactful on behaviour and attitudes on such subject, and the authority responsible in this regard is the Swedish Energy Agency in Eskilstuna, Sweden. The purpose of this thesis is to understand the complicated transformation towards sustainable energy production and consumption in society, through the experience and knowledge of the Swedish Energy Agency. Economic growth desires, path dependence (in both societal behaviour and attitudes, as well as economic theorems) and risk perceptions are the subjects in discussion as they relate to the transformation.  The findings revealed that the Swedish Energy Agency is aware of societal behaviour and attitudes toward change to some extent; nonetheless, they must enhance the information provided to society. To have a greater impact on the majority of society, their action plans and strategies must become more adaptive to particular identities. Most policymaking in our culture is driven by economic incentives, but the Swedish Energy Agency believes that if they could raise knowledge, behaviour, and attitudes toward long-term change, the government (who is responsible for the agency's missions) would change. Because our government is a democracy, it reflects what our society desires.

The aim of this study was to see if the users identified principles for behavior change, and further investigate how users reflected on the implementation of these principles. The aim of this study was also to find out how users experienced that the effect of these principles contributed to the reduction of electricity consumption. There are persuasive technologies that aim to get people to save their consumption. There are many different applications that aim to get people to monitor behaviors and then change behaviors. The applications included in this study were Eon, Greenely and Tibber. PSD-principles, Oinas-Kukkonen and Harjumaa's design principles are used as quality checklists to be able to evaluate persuasive systems. The principles were divided into four main categories which were primary task support, dialogue support, system credibility and social support. These were used to answer the questions. A: What design principles for behavior change can be identified? B: How do users reflect on theimplementation of these principles? C: How do users feel that the effect of these principles contributes to reducing electricity consumption? The chosen method was qualitative and it was divided into 3 phases. The first phase was a heuristic evaluation. The second phase was a pilot diary study. In the third phase, semi-structured interviews were conducted and this interview template was based on the pilot diary study and on the heuristic evaluation. The results showed that all principles within the main categories where identified in the applications. When it came to the implementation of the principles, the reflections from the users were different. Verifiability within the system's credibility was for example perceived by respondent 1 as less convincing, while respondent 4 perceived the implementation as positive and good. The experiences here also varied concerning how the users experienced that the effect of the principles contributed to reducing electricity consumption. The motivation was positively affected to a small but limited extent for the principles within the main categories primary tasks support and social support. Conclusions drawn from the studies were as follows. Users would wish for expanding the possibility of direct reporting of electricity consumption. Better statistical data to better compare households with similar comparable conditions would be desirable. Being able to see how much money you could save on reducing your electricity consumption was an important driving force. It would be positive if the opportunity to see this improved. / Syftet med denna studie var att se om användarna identifierade principer för beteendeförändring samt se hur användarna reflekterade kring implementeringen av dessa principer. Syftet var också att ta reda på hur användarna upplevde att effekten av dessa principer bidrog till att minska elförbrukningen.Det finns övertygande teknik som syftar till att få människor att spara sin konsumtion. Det finns många olika applikationer som syftar till att få människor att övervaka beteenden för att sedan ändra dem. De applikationer som ingick i studien var Eon, Greenely och Tibber. PSD-principerna, Oinas-Kukkonen och Harjumaas designprinciper användes som checklistor på kvalitet för att kunna utvärdera övertygandesystem. De delades in i fyra huvudkategorier som var primärt uppgifts stöd, dialogt stöd, systemets trovärdighet och socialt stöd. Dessa användes för att svara på frågeställningarna. A: Vilka designprinciper för beteendeförändring kan identifieras? B: Hur reflekterar användare över implementeringen av dessa principer? C: Hur upplever användarna att effekten av dessa principer bidrar till att minskaelförbrukningen?Vald metod var kvalitativ och denvar indelad i 3 faser. Den första fasen var en heuristisk utvärdering. Den andra var en pilotdagboksstudie. I den tredje fasen gjordes semi-struktureradeintervjuer och i denna baserades intervjumallen på en pilotdagboksstudie och på den heuristiska utvärderingen. Resultatet visade att alla principer inom huvudkategorierna identifierades i applikationerna. När det gällde implementeringen av principerna var reflektionerna från användarna olika. Verifierbarhet inom systemets trovärdighet upplevdes exempelvis av svarsperson 1 som mindre övertygande medan svarsperson 4 upplevde implementationen som positiv och bra. När det kom till hur användarna upplevde att effekten av principerna bidrog till att minska elförbrukningen var upplevelserna även här varierande. Motivationen påverkades positivt i liten men begränsad omfattning för principerna inom huvudkategorierna primärt uppgifts stöd och social support. Slutsatser som drogs från studien var följande. Användarna skulle önska utökad möjlighet till direkt rapportering av förbrukning av elkonsumtion. Bättre statistiskt underlag för att bättre kunna jämföra hushåll med liknande jämförbara förhållanden skulle vara önskvärt. Att kunna se hur mycket pengar man kunde spara på att minska sin elkonsumtion var en viktig drivkraft. Det skulle vara positivt om möjligheten till att se detta förbättrades.
