  1. 1. Energy Efficiency Improvements of Tumble Dryers : -Technical Development, Laundry Habits and Energy Labelling

    Författare :Lena Stawreberg; Lars Nilsson; Jonas Berghel; Roger Renström; Björn Palm; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; drying; domestic; energy efficiency; textile; energy labelling standard; Thermal energy engineering; Termisk energiteknik; Miljö- och energisystem; Environmental and Energy Systems;

    Sammanfattning : Tumble dryers are becoming more and more common in ordinary households as a complement to the washing machine. Tumble dryers offer a fast drying cycle independent on weather conditions and require small space. They do, however, considering the large number of units use a large amount of electricity. LÄS MER

  3. 2. Hydrogen in the European energy system - The cost dynamics and the value of time-shifting electricity generation

    Författare :Simon Öberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cost; energy systems modeling; Hydrogen; gas turbine; system dynamics; time-shifting;

    Sammanfattning : If the European Union is to become climate-neutral by Year 2050, as envisioned in the European Green Deal, the European energy system must undergo an unprecedented transformation towards eliminating its carbon emissions. For this transition, renewable electricity plays a central role, not only in replacing the current fossil-based electricity generation, but also in promoting the electrification of other sectors, such as transport and industry, sectors which are currently based on fossil fuels.

  4. 3. Designing Energy-Sensitive Interactions : Conceptualising Energy from the Perspective of Electric Cars

    Författare :Anders Lundström; Jan Gulliksen; Kristina Höök; Cristi Bogdan; Ron Wakkary; KTH; []
    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

  5. 4. What have residents got to do with it? : Variations in energy use and energy-related behaviours in single-family houses

    Författare :Carolina Hiller; Jesper Arfvidsson; Thorbjörn Laike; Avdelningen för Byggnadsfysik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; energy use variations; energy-related behaviour; single-family houses; households; residents; multi-disciplinary; field measurements; times-use diaries; energy use over time; load curves; power peaks; energy measurements; residential houses;

    Sammanfattning : To achieve global energy goals, energy use in residential buildings must decrease. The implementation of technical measures is crucial but alone it is not sufficient; residents need to change their behaviour as well. LÄS MER

  7. 5. Goda råd är inte dyra! : Om personlig energirådgivning i ett alltmer digitaliserat samhälle

    Författare :Are Kjeang; Venkatesh Govindarajan; Jenny Palm; Magnus Ståhl; Leif Gustavsson; Karlstads universitet; []
