1. 11. Energy from Ocean Waves : Full Scale Experimental Verification of a Wave Energy Converter

   Författare :Rafael Waters; Mats Leijon; Jan Sundberg; Jonny Hylander; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wave power; wave energy converter; sea trials; ocean energy; linear generator; point absorber; search coil; wave climate; utilization; Engineering physics; Teknisk fysik;

   Sammanfattning : A wave energy converter has been constructed and its function and operational characteristics have been thoroughly investigated and published. The wave energy converter was installed in March of 2006 approximately two kilometers off the Swedish west coast in the proximity of the town Lysekil. LÄS MER

3. 12. Building-related renewable electricity production with storage and energy-efficient buildings : Exploring barriers, drivers and quality assurance

   Författare :Anna-Lena Lane; Mathias Cehlin; Thomas Olofsson; Högskolan i Gävle; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy efficiency gap; energy performance gap; ByggaE; battery storage; barriers; drivers; Non-energy benefits NEB; questionnaire; quality assurance; PV; energieffektivisering; energieffektiva byggnader; kvalitetssäkring; byggprocessen; ByggaE; solel; batterilager; hinder; drivkrafter; enkätstudie; Hållbar stadsutveckling; Sustainable Urban Development;

   Sammanfattning : There is a need to reduce unsustainable use of fossil fuels. Increased usage of renewable energy by combined use of photovoltaic solar panels (PV) with battery storage is one way. Another way is to increase awareness of energy usage and reduce the energy performance gap by building energy-efficient buildings. LÄS MER

4. 13. Numerical approaches to droplet growth in atmospheric turbulence

   Författare :Xiang-Yu Li; Axel Brandenburg; Gunilla Svensson; Luca Brandt; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; turbulence; coagulation; condensation; rain formation; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

   Sammanfattning : The bottleneck problem of cloud droplet growth is one of the most challenging problems in cloud physics. Cloud droplet growth is neither dominated by con-densation nor gravitational collision in the size range of 15–40 μm in radius. Turbulence-generated collision has been thought to be the mechanism to bridge the size gap, i.e. LÄS MER

5. 14. Walking along the lines of power. A systems approach to understanding co-emergence of society, technology and nature in processes of rural electrification

   Författare :Helene Ahlborg; Chalmers tekniska högskola; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

   Sammanfattning : Many African governments, international and local organizations involved in development policy and practice consider rural electrification (RE) to be a priority. In the absence of electric grid infrastructure, rural populations rely on, for example, diesel generators, batteries and solar panels for their electricity supply and on kerosene, wood and charcoal for lighting and heating purposes.

7. 15. New methods and applications to explore the dynamics of least-cost technologies in geospatial electrification modelling

   Författare :Andreas Sahlberg; Francesco Fuso Nerini; William Usher; Mark Howells; James Morrissey; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Technology;

   Sammanfattning : Access to modern energy services is a pre-requisite for sustainable development. As such, Sustainable Development Goal (SDG) 7 aims to ensure access to affordable, reliable, sustainable and modern energy for all. However, as of 2021, 675 million people lack access to electricity, and 2.3 billion people lack access to clean cooking fuels. LÄS MER
