  1. 21. PV water pumping systems for grassland and farmland conservation

    Författare :Pietro Elia Campana; Jinyue Yan; Bengt Perers; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : Grassland degradation is considered as one of the worst environmental and economic problems in China because of the negative impacts on water and food security. The application of the photovoltaic water pumping (PVWP) technology for irrigation is an innovative and sustainable solution to curb the progress of grassland desertification and to promote the conservation of farmland in remote areas.

  3. 22. Optimisation of Local and National Energy Systems : Development and Use of the MODEST Model

    Författare :Dag Henning; Carl-Johan Fogelholm; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Energy may be supplied by a multitude of components. Computer simulation helps in finding a beneficial system design. The energy-system optimisation model MODEST has been developed, and it has been applied to municipal, regional, and national energy systems. LÄS MER

  4. 23. Makten över energin : policyprocesser i två kommuner 1977–2001

    Författare :Jenny Palm; Jane Summerton; Mats Bladh; Agneta Blom; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Policy; power; system; energy; municipalities; supply; energy conservation; environment; agenda 21; Sweden; Linköping; Norrköping; Energi; Kommun; Linköping; Norrköping; Policy; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Sammanfattning : Municipalities have traditionally played key roles in the Swedish energy system as suppliers of gas, electricity and district heating to the public sector and end-use consumers. Sweden has a tradition of strong local self-government, and the municipalities are expected to play important roles in implementing national energy strategies and formulating municipal ones. LÄS MER

  5. 24. Design Beyond Interventions – Supporting Less Energy-reliant Activities in the Everyday

    Författare :Anneli Selvefors; Chalmers tekniska högskola; []
    Nyckelord :HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Activities; Energy use; Enabling preconditions; Design for Sustainability; Everyday life; Energy conservation;

    Sammanfattning : This thesis addresses challenges and opportunities for product design to contribute to domestic energy conservation. The overall aim of the thesis is that of increasing the understanding of people’s energy use and their use of energy-reliant artefacts in the everyday in order to propose ways of supporting energy conservation through design.
