  1. 1. Renewable Energy in Energy-Efficient, Low-Pollution Systems

    Författare :Bengt Johansson; Miljö- och energisystem; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydrogen; ethanol; methanol; rape methyl ester; biomass; renewable energy; cogeneration; energy efficiency; scenarios; air pollution; carbon dioxide; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp;

    Sammanfattning : Energy use accounts for the dominating fraction of total sulphur dioxide (SO2), nitrogen oxide (NOx), volatile organic compounds (VOCs) and carbon dioxide (CO2) emissions. In this thesis, different strategies for reducing these emissions are evaluated, using a bottom-up approach. The thesis is divided in two parts. LÄS MER

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

    Författare :Kerstin Åstrand; Miljö- och energisystem; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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.

  3. 3. Energy analysis for sustainable mega-cities

    Författare :Aumnad Phdungsilp; Björn Palm; Ivo Martinac; Charles Heaps; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Asian mega-cities; energy demand; metabolism of cities; energy modeling; sustainable energy; energy planning; multi-criteria decision-making; Mechanical energy engineering; Mekanisk energiteknik;

    Sammanfattning : ABSTRACT Cities throughout Asia have experienced unprecedented economic development over the past decades. In many cases this has contributed to their rapid and uncontrolled growth, which has resulted in a multiplicity of problems, including rapid population increase, enhanced environmental pollution, collapsing traffic systems, dysfunctional waste management, and rapid increases in the consumption of energy, water and other resources.

  4. 4. 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 :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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

  5. 5. Small-Scale Decentralized Energy Systems : optimization and performance analysis

    Författare :Sara Ghaem Sigarchian; Viktoria Martin; Anders Malmquist; Erik Dahlquist; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Small-scale polygeneration energy systems; techno-economic optimization; renewable energy; operating strategy; particle swarm optimization; optimization algorithm; decentralized energy system;

    Sammanfattning : Small-scale polygeneration energy systems, providing multiple energy services, such as heating, electricity, cooling, and clean water, using multiple energy sources (renewable and non-renewable) are considered an important component in the energy transition movement. Exploiting locally available energy sources and providing energy services close to the end users have potential environmental, economic, and societal benefits. LÄS MER
