  1. 6. Public intermediaries in the energy transition - A study of municipal energy advisors in Sweden

    Författare :Lisa Bastås; Chalmers tekniska högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy advising; public; intermediaries; solar photovoltaic; private; energy; Sweden; transitions; sustainability;

    Sammanfattning : To mitigate climate change, a transition toward more sustainable energy production and consumption is crucial. In particular, this requires widespread adoption of renewable electricity technologies, such as solar photovoltaics (PV). As the adoption of such technologies can be challenging for new adopters, support actors such as intermediaries (i.e. LÄS MER

  2. 7. Applicability of thermal energy storage in future district heating system - Design methodologies and performance evaluations

    Författare :Yichi Zhang; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; low-temperature district heating; demand-side management; low energy buildings; Thermal energy storage; district heating; variable renewable energy;

    Sammanfattning : District heating (DH) enables efficient and economical utilization of energy resources to satisfy the heat and hot water demands in buildings and is, thereby, well-established in Northern European countries. To achieve the future renewable energy system, the current DH systems are proved to undergo transitions towards the future DH systems, with major characteristics including renewable-based heat sources, low temperature networks, lower heating demands and smart controls.

  3. 8. Transition pathways for future district heating and cooling systems with thermal energy storage

    Författare :Yichi Zhang; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; transition roadmap; bidirectional system; uncertainty analysis; Thermal energy storage; district heating and cooling;

    Sammanfattning : Buildings’ heating and cooling account for more than 20% of the final energy use within the European countries and are dominated by non-renewable resources. Future district energy systems should enable efficient, fossil-free, and economical energy supply at operating temperatures that end users can directly utilize. LÄS MER

  4. 9. Energy consumption transition : final household energy consumption in the case of Sweden 1920-2010

    Författare :Mikael Levin; Lars-Fredrik Andersson; Ann-Kristin Bergquist; Thomas Pettersson; Bengt Kriström; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; economic history; households; energy transition; energy consumption; residential; electrical appliances; Carbon dioxide; emission; ekonomisk historia; Economic History;

    Sammanfattning : This licentiate thesis examines households’ final energy consumption over the long run by measuring their final energy use and examining how structural, institutional and economic factors affected the demand for energy in the residential sector during the period 1920-2010, a period covering the transition from traditional to fossil to renewable energy carriers. I believe that wider understanding of the historical energy transition and energy consumption within the residential sector might help us gain important insights into the long-run development and the factors affecting energy consumption among the households.

  5. 10. Heat decarbonization in municipalities - Accounting for the local spatial context in techno-economic modeling

    Författare :Hyunkyo Yu; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optimization; spatial analysis; Participatory modeling; local heat decarbonization; energy transition;

    Sammanfattning : In Europe, 57% of the energy used for space and water heating is derived from the combustion of fossil fuels, whereas only 24% comes from renewables. Compared to the wide-reaching transmission of electricity between countries, the supply of heat predominantly occurs at the local or individual level. LÄS MER
