  1. 1. Natural resources and sustainable energy Growth rates and resource flows for low-carbon systems

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Simon Davidsson; Uppsala universitet.; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; low-carbon technology; renewable energy; energy transitions; critical materials; energy metals; material flows; net energy; EROI; life cycle assessment; LCA; growth curves; curve fitting; resource depletion; Natural Resources and Sustainable Development; Naturresurser och hållbar utveckling;

    Sammanfattning : Large-scale deployment of low-carbon energy technologies is important for counteracting anthropogenic climate change and achieving universal energy access. This thesis explores potential growth rates of technologies necessary to reach a more sustainable global energy system, the material and energy flows required to commission these technologies, and potential future availability of the required resources.

  2. 2. Designing Energy-Sensitive Interactions Conceptualising Energy from the Perspective of Electric Cars

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Anders Lundström; KTH.; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Interaction design; Electric vehicles; Range anxiety; Energy management; Battery management; Intergy; Exergy; Anergy; Energy-Sensitive Interactions; Energy dynamics; Energy compromises; Empowerment; Resourceful interaction; Människa-datorinteraktion; Human-computer Interaction;

    Sammanfattning : As technology is increasingly used in mobile settings, energy and battery management is becoming a part of everyday life. Many have experienced how quickly a battery can be depleted in a smartphone, laptop or electric cars, sometimes causing much distress. LÄS MER

  3. 3. Tracking Emissions Reductions and Energy Efficiency in the Steel Industry

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Johannes Morfeldt; KTH.; [2017]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy efficiency; greenhouse gas emissions reductions; indicators; iron and steel industry; systems analysis; energieffektivitet; växthusgasutsläppsminskning; indikatorer; järn- och stålbranschen; systemanalys; Energiteknik; Energy Technology;

    Sammanfattning : The iron and steel industry has become increasingly globalised. Market conditions are also changing and de-carbonisation of production is challenging.The objective of this thesis is to assess how energy efficiency and greenhouse gas emissions reductions can be promoted and effectively monitored in the steel industry.

  4. 4. Improved building energy simulations and verifications by regression

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Jimmy Vesterberg; Umeå universitet.; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Calibrated simulations; Energy signature; Regression; BES; IDA ICE; Multifamily buildings; EUI;

    Sammanfattning : It is common with significant differences between calculated and actual energy use in the building sector. These calculations are often performed with whole building energy simulation (BES) programs. In this process the analyst must make several assumptions about the studied building and its users.

  5. 5. Spatially explicit electrification modelling insights Applications, benefits, limitations and an open tool for geospatial electrification modelling

    Detta är en avhandling från Stockholm, Sweden : KTH Royal Institute of Technology

    Författare :Dimitris Mentis; KTH.; [2017]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Technology;

    Sammanfattning : Developing countries confront the challenge of generating more electricity to meet demands in a sustainable manner. According to the World Bank’s 2015 Global Tracking Framework, roughly 15% of world population (or 1.1 billion people) lack access to electricity, and many more rely on poor quality electricity supplies.
