1. 11. Improving Ship Energy Efficiency through a Systems Perspective

   Författare :Francesco Baldi; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; modelling; shipping; exergy analysis; energy systems; energy efficiency; energy analysis; systems analysis;

   Sammanfattning : The last years have been particularly challenging for the shipping industry. Fuel prices have increased to levels only seen during the oil crisis in the 70's, and environmental regulations have grown much stricter than in the past. Climate change, at a global level, is going to become a major threat to society. LÄS MER

3. 12. Applications of artificial neural networks for time series data analysis in energy domain

   Författare :Fan Zhang; Hasan Fleyeh; Stawomir Nowaczyk; Högskolan Dalarna; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Deregulated energy market; electricity prices; district heating; energy efficiency; neural networks; Complex Systems – Microdata Analysis; Komplexa system - mikrodataanalys;

   Sammanfattning : With the development of artificial intelligence techniques and increased installation of smart meters in recent years, time series analysis using historical data in the energy domain becomes applicable. In this thesis, microdata analysis approaches are used, which consist of data acquisition, data processing, data analysis and data modelling, aiming to address two research problems in the energy domain.

4. 13. Energy Efficiency through Thermal Energy Storage : Possibilities for the Swedish Building Stock

   Författare :Johan Heier; Viktoria Martin; Chris Bales; Signhild Gehlin; Högskolan Dalarna; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal energy storage; buildings; energy efficiency; energy savings; peak load reduction; Swedish building stock; termisk energilagring; byggnader; energieffektivisering; energibesparing; toppbelastningsutjämning; Sveriges byggnadsbestånd; Värmelagring i byggnader;

   Sammanfattning : The need for heating and cooling in buildings constitutes a considerable part of the total energy use in a country and reducing this need is of outmost importance in order to reach national and international goals for reducing energy use and emissions. One important way of reaching these goals is to increase the proportion of renewable energy used for heating and cooling of buildings. LÄS MER

5. 14. Energy Policy Instruments Perspectives on their Choice, Combination and Evaluation

   Författare :Kerstin Åstrand; Miljö- och energisystem; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy systems; policy instrument choice; socio-technical systems; policy instrument combination; Energiforskning; Energy research; Samhällsvetenskaper; Social sciences; Sweden.; evaluation; Environmental technology; pollution control; Miljöteknik; wind energy policy; green certificate trading scheme; market creation; wind power; Public policy instruments; wind turbine development; kontroll av utsläpp; renewable energy; energy policy;

   Sammanfattning : Abstract The thesis aims at providing a better understanding of public policy instruments used in policy-making within the energy sector, particularly regarding their role in the change towards an increased use of renewable energy sources for generation of electricity. The research was guided by an underlying assumption that a markedly higher proportion of the energy generated from renewable sources can be considerably enhanced by use of policy instruments that support the development and the market creation of new, renewable energy technologies.
