  1. 21. 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.

    Författare :Tina Lidberg; Louise Ödlund; Thomas Olofsson; Erik Dahlquist; Högskolan i Gävle; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; building simulation; combined heat and power; district heating; domestic hot water; energy efficiency; greenhouse gas emission; low-temperature; multi-family building; primary energy; refurbishment; byggnadsimulering; energieffektivitet; flerfamiljshus; fjärrvärme; kraftvärme; lågtemperatur; primärenergi; renovering; tappvarmvatten; växthusgas; Hållbar stadsutveckling; Sustainable Urban Development; Reesbe företagsforskarskola;

    Sammanfattning : Improving energy performance of existing buildings is an important part in decreasing energy use and in turn reducing greenhouse gas emissions and primary energy use. To be able to evaluate how energy refurbishment influences greenhouse gas emissions and primary energy use a wider system perspective is needed which puts the building in its context. LÄS MER
