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

    Detta är en avhandling från Gävle : Gävle University Press

    Författare :Åsa Hadin; Högskolan i Gävle.; [2018]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

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

    Detta är en avhandling från Uppsala : Geotryckeriet

    Författare :Simon Davidsson; Uppsala universitet.; [2015]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 3. Renewable composites prepared from biobased thermoset resins

    Detta är en avhandling från Göteborg : Chalmers tekniska högskola

    Författare :Dan Åkesson; Högskolan i Borås.; [2009]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; natural fibres; composites; Energi och material; Renewable; natural fibre; composite; biobased thermoset resin;

    Sammanfattning : In our efforts to create a more sustainable society, several researchers have tried to prepare composites from renewable materials in recent years. The use of natural fibres for reinforcement of composites has been relatively well studied. LÄS MER

  4. 4. Biohybrid Polymer Electrodes for Renewable Energy Storage

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Fátima Nadia Ajjan Godoy; Linköpings universitet.; Linköpings universitet.; [2017]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : 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. LÄS MER

  5. 5. Entering renewable electricity production An actor perspective

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Ingrid Mignon; Linköpings universitet.; Linköpings universitet.; [2014]
    Nyckelord :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;

    Sammanfattning : 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.
