  1. 1. Dynamics of Energy Systems - Methods of analysing technology change

    Author : Lena Neij; Internationella miljöinstitutet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy research; evaluation; market transformation; PV modules; wind power; experience curves; air-distribution; lighting; vintage models; sustainable energy; renewable energy; energy efficiency; Energy; energy system; Energiforskning; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp;

    Abstract : Technology change will have a central role in achieving a sustainable energy system. This calls for methods of analysing the dynamics of energy systems in view of technology change and policy instruments for effecting and accelerating technology change. In this thesis, such methods have been developed, applied, and assessed. READ MORE

  2. 2. Global energy transitions : Renewable energy technology and non-renewable resources

    Author : Simon Davidsson; Mikael Höök; Kjell Aleklett; Björn Sandén; Uppsala universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy transitions; natural resources; renewable energy; sustainable development; growth curves; Natural Resources and Sustainable Development; Naturresurser och hållbar utveckling;

    Abstract : The global energy system is dominated by the use of fossil fuels. This system suffers from several problems, such as different environmental issues, while the long-term energy security is sometimes questioned. READ MORE

  3. 3. Energy Use, Efficiency Gains and Emission Abatement in Transitional Industrialised Economies: Poland and the Baltic States

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

    Author : Kerstin Åstrand; Miljö- och energisystem; []
    Keywords : 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;

    Abstract : 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.

    Abstract : Energy from solar photovoltaic (PV) are generated as direct current (DC) and almost all of today’s electrical loads in residential buildings, household appliances and HVAC system (Heating Ventilation and Air-conditioning) are operated on DC. For a conventional alternating current (AC) distribution system this requires the need for multiple conversion steps before the final user-stage. READ MORE
