    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

  4. 3. Island-based Polygeneration Systems : On the Feasibility of Solar-Biomass-driven Distributed Concepts

    Författare :Moritz Wegener; Anders Malmquist; Andrew R. Martin; Antonio Isalgué; Natasa Nord; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polygeneration; Distributed energy systems; Biomass; Solar energy; PV-Battery; Small-scale energy systems; techno-economic analysis; Island-based systems; Energy Technology; Energiteknik;

    Sammanfattning : The colossal risks and challenges posed by climate change require innovative solutions that must fulfil energy service demands sustainably. The concept of small-scale, biomass-based polygeneration (SBP) is one such technological approach, which optimizes locally supplied fuels to provide several energy services like electricity, heating, cooling, potable water, and/or bio-chemical products.

  5. 4. PV water pumping systems for grassland and farmland conservation

    Författare :Pietro Elia Campana; Jinyue Yan; Bengt Perers; Mälardalens högskola; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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.
