  1. 1. 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 :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; 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.

  2. 2. Low-energy buildings : energy use, indoor climate and market diffusion

    Författare :Johannes Persson; Stefan Grönkvist; Svend Svendsen; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; building energy simulations; energy efficiency gap; energy use; indoor climate; low-energy buildings;

    Sammanfattning : Low-energy buildings have, in recent years, gained attention and moved towards a large-scale introduction in the residential sector. During this process, national and international criteria for energy use in buildings have become stricter and the European Union has through the Energy Performance of Buildings Directive imposed on member states to adapt their building regulations for ‘Nearly Zero Energy Buildings’, which by 2021 should be standard for new buildings.

    Sammanfattning : This thesis is a study of how energy use and air pollution in Poland, Estonia, Latvia and Lithuania have been affected by the economic transition after 1989. It consists of six articles, which examine three different aspects of these changes. LÄS MER

  4. 4. Improved Self-Consumption of Photovoltaic Electricity in Buildings : Storage, Curtailment and Grid Simulations

    Författare :Rasmus Luthander; Joakim Widén; Joakim Munkhammar; Ewa Wäckelgård; Nicholas Etherden; Uppsala universitet; []

    Sammanfattning : The global market for photovoltaics (PV) has increased rapidly: during 2014, 44 times more was installed than in 2004, partly due to a price reduction of 60-70% during the same time period. Economic support schemes that were needed to make PV competitive on the electricity market have gradually decreased and self-consumption of PV electricity is becoming more interesting internationally from an economic perspective.

    Sammanfattning : In the transition towards a sustainable energy system, building mounted solar photovoltaics (PV) have unique benefits; they require no additional land and the energy is generated directly at load centers. Within residential buildings, multi-family homes (MFH) are particularly interesting because of the economies of scale and their greater potential for emissions reductions. LÄS MER
