  1. 1. Biogas in Sweden - Opportunities and challenges from a systems perspective

    Författare :Mikael Lantz; Miljö- och energisystem; []
    Nyckelord :Biogas; Policy Instruments; Techno-economic assessments; Environmental assessments;

    Sammanfattning : Addressing today’s challenges of reducing our dependence on fossil fuels and related emissions of greenhouse gases requires measures such as increased energy efficiency and replacement of fossil energy carriers with renewable ones. Biogas is one of the fastest growing renewable energy sources in the world and the overarching purpose of the research presented in this doctoral thesis is to explore the prospects of an increased production and utilization of biogas in a Swedish context.

    Sammanfattning : Energy use in the urban environment is vital for the proper functioning of our society, and in particular, comfort heating –or cooling– is a central element of our energy system often taken for granted. Within this context, district energy systems and especially, district heating (DH) systems must evolve to adapt to the upcoming decades-long transition towards a sustainable energy system. LÄS MER

  5. 5. Values Behind Welfare Technology and Their Possible Realization : Creation of a Technology Evaluation Method for Care Practices

    Författare :Annika Hasselblad; Leif Olsson; Katarina L Gidlund; Aron Larsson; Xiu Gu; Mittuniversitetet; []
    Nyckelord :Care; evaluation; technology; values; welfare technologies.;

    Sammanfattning : In 2018 the Swedish government approved a SEK 350 million grant to increase the municipal implementation and use of welfare technologies in areas such as health care, care, and social service. Welfare technologies have been criticized for their effects on care workers’ work environment, such as increased stress due to time and performance demands. LÄS MER
