  1. 1. From waste problem to renewable energy resource exploring horse manure as feedstock for anaerobic digestion

    University dissertation from Gävle : Gävle University Press

    Author : Åsa Hadin; Högskolan i Gävle.; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; horse manure; environmental systems analysis; energy systems; renewable energy; environmental impact; anaerobic digestion; biogas; biofertilizer; systems perspective; bedding; incineration; composting; horse manure utilization;

    Abstract : A sustainable energy system requires, according to energy policies, reduced emissions of greenhouse gases, increased ratio of renewable sources of energy and more efficient use of energy. Horse manure could be regarded as waste, but also as a resource for renewable energy and plant nutrients. READ MORE

  2. 2. Global energy transitions Renewable energy technology and non-renewable resources

    University dissertation from Uppsala : Geotryckeriet

    Author : Simon Davidsson; Uppsala universitet.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy transitions; natural resources; renewable energy; sustainable development; growth curves; Natural Resources and Sustainable Development; Naturresurser och hållbar utveckling;

    Abstract : The global energy system is dominated by the use of fossil fuels. This system suffers from several problems, such as different environmental issues, while the long-term energy security is sometimes questioned. READ MORE

  3. 3. Renewable composites prepared from biobased thermoset resins

    University dissertation from Göteborg : Chalmers tekniska högskola

    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Daily and seasonally fluctuating energy supply and demand requires adequate energy storage solutions. In recent years electrochemical supercapacitors have attracted considerable attention due to their ability to both store and deliver electrical energy efficiently. READ MORE

  5. 5. Entering renewable electricity production An actor perspective

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Ingrid Mignon; Linköpings universitet.; Linköpings universitet.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Renewable electricity production; new entrants; energy transition; energy policy; innovation; entrepreneurship; institutional theory; innovation-­adoption; implementation;

    Abstract : Although energy transition is considered one of the main challenges of our time, little attention has traditionally been paid to the actors participating in this transition, such as the producers of renewable electricity. Previous energy policy literature and policy- makers have assumed that these producers are incumbent actors of the current energy system, that is to say, large utilities producing both renewable and fossil-fueled electricity.
